DANGER!

NATURAL GAS AND LIQUEFIED PETROLEUM MODELS

Both LP and natural gas have an odorant added to aid in detecting a gas leak.

Some people may not physically be able to smell or recognize this odorant. If you

are unsure or unfamiliar with the smell of LP or natural gas, ask the gas supplier.

Other conditions, such as “odorant fade”, which causes the odorant to diminish in

intensity, can also hide or camouage a gas leak. Always check with commercial

leak detector or soapy water.

• Gas detectors are recommended in LP and natural gas applications and

their installation should be in accordance with the detector manufacturer’s

recommendations and/or local laws, rules, regulations or customs.

• Water heaters utilizing LP gas are dierent from natural gas models. A natural

gas water heater will not function safely on LP gas and vice versa.

• No attempt should ever be made to convert the water heater from natural gas

to LP gas. To avoid possible equipment damage, personal injury or re, do not

connect the water heater to a fuel type not in accordance with the unit data

plate; propane for propane units and natural gas for natural gas units. These

units are not certied for any other fuel type.

• LP water heaters should not be installed· below grade (for example, in a

basement) if such installation is prohibited by federal, state and/or local laws,

rules, regulations or customs.

• Propane or LP gas must be used with great caution. It is heavier than air and

will collect rst in lower areas making it hard to detect at nose level.

• Before attempting to light the water heater, make sure to look and smell for

gas leaks. Use a soapy solution to check all gas ttings and connections.

Bubbling at a connection indicates a leak that must be corrected. When smelling

to detect a gas leak, be sure to sni near the oor also.

• It is recommended that more than one method, such as soapy solution, gas

detectors, etc., be used to detect leaks in gas applications.

Notice: If a gas leak is present or suspected:

• DO NOT attempt to nd the cause yourself.

• DO NOT try to light any appliances.

• DO NOT touch any electrical switch.

• DO NOT use any phone in your building.

• Leave the house immediately and make sure your family and pets leave

also.

• Leave the doors open for ventilation and contact the gas supplier, a

qualied service agency or the re department.

• Stay away from the house (or building) until the service call has been

made, the leak is corrected and a qualied agency has determined the

area to be safe.

• No valve of any type should be installed between the

relief valve and the water heater.

• Discharge from the relief valve should be piped to a

suitable drain to eliminate potential water damage. Piping

used should be of a type approved for the distribution of

hot water.

• Hot and cold water lines should be insulated up to the

water heater.

• The discharge line must be NO SMALLER than the outlet

of the valve and must pitch downward to allow complete

drainage (by gravity) of the relief valve and discharge line.

• The end of the discharge line should not be threaded or

concealed and should be protected from freezing. No

valve of any type, restriction or reducer coupling should

be installed in discharge line.

NOTICE: Local codes govern the installation of relief valves. If local codes require that a temperature

and pressure relief valve should be installed the manufacturer recommends a type 40XL Watts T&P

relief valve or an equivalent model be used.

NOTICE: Manual operation of relief valves should be performed at least once a year. Turn o the

electrical power and gas shuto valve. Lift and release lever on the relief valve and check the manual

operation of the relief valve. You should take precaution to avoid contact with the hot water coming

out of the relief valve and to prevent water damage.

NOTICE: If the relief valve on the system discharges periodically, this may be due to thermal expansion

in a closed water supply system. Contact the water supplier or local plumbing inspector on how to

correct theis situation. Do not plug the relief valve.

A new pressure relief valve, complying with the Standard for relief Valves and Automatic Gas Shut-O

Devices for Hot Water Supply Systems, ANSI Z21.22, must be installed at the hot water outlet connection of

the water heater at the time of installation. Local codes shall govern the installation of relief valves.

For safe operation of the water heater, be sure that:

NOTICE: The above illustrates

a pressure only relief valve.

If local codes require a

combination temperature

and pressure relief valve be

installed, an extension piece

may be needed.

Pressure Testing the Gas Supply System

WARNING: Install a gas pressure regulator, in the gas supply line, which does not exceed the

maximum supply pressure.

DO NOT use an industrial type gas regulator.

Failure to isolate heater during pressure test can damage internal components voiding warranty. The water heater

and its individual shuto valve must be disconnected from the gas supply piping system during any pressure

testing of that system at testy pressures in excess of 1/2 psi. The water heater must be isolated from the gas

piping system by closing the manual gas shut-o valve during any pressure testing of the gas supply piping at test

pressures equal to or less than 1/2 psi (14’w.c.).

• To supply hot water to upper oors,

additional water pressure (0.44 psi/ft)

must be ensured.The measurement should

be calculated by the distance between the

water inlet of the water heater (ground

level) to the hot water faucet (upper oor level).

• Well water systems should be set at a

range of 50-60 psi.

• When the water is supplied from a water

supply tank, the height of the tank and the

diameter of the pipes and their relation to

water pressure, should be taken into

consideration. Gravity water pressure is

not recommended.

NOTICE: If the water ow resistance of a shower

head is too high, the burner in the water heater

will fail to ignite. Keep the shower head clean from

debris that could cause additional pressure drop.

NOTICE: If using mixing valves on the outlet,

choose one which prevents cold water pressure

from overcoming hot water line pressure.

IMPORTANT: Do not apply heat to the HOT or

COLD water connections. Any heat applied to the

water supply ttings will permanently damage the

internal components of the water heater.

Water Supply Connections

Plumbing should be carried out by a qualied

plumber in accordance with local codes.

Use approved plumbing materials and tools only.

To conserve energy and to prevent freezing,

insulate both cold and hot water supply lines. DO

NOT cover the drain valves.

To ensure proper operation of the water heater,

the following water pressure guidelines should be

followed:

• Operation of the water heater requires the

minimum water pressure of 14 psi and a

minimum water ow rate of 0.75 gpm.

• Additional water pressure is required for

long pipe runs and outlet tting(s) water

pressure drops.

• To maintain proper performance, ensure

sucient water supply pressure. The

Required Water Pressure = Min. Operating

Water Pressure (14 psi) + Pipe Pressure

Loss + Faucet and Shower Pressure Loss +

Safety Margin (more than 5 psi).

Mounting the EL22 Water Heater

Make sure the location of the water heater allows for easy access

and operation. The water heater should be located in an area where leakage of the

tank or connections will not result in damage to the area adjacent to the water heater

or to lower oors of the structure. When such locations cannot be avoided, it is

recommended that a suitable drain pan, adequately drained, be installed under the

appliance. The pan must not restrict combustion air ow.

In case of dry wall or concrete wall use dry wall anchors or lag bolts.

The water heater requires 120VAC/ 60Hz. Have a receptacle with

ground terminal near the water heater. The length of the power

supply cord is 5 feet.

Drill the holes as per the sizes in the gure to the left, put 2 expansion screws into the

top holes, and 2 rubber screws into the bottom holes.

Proper operation of the water heater requires air for combustion and ventilation. Provisions

for combustion and ventilation air must comply with referenced codes and standards.

Combustion and Ventilation Air

Installing the EL22-I water heater continued....

A conned space is one having a volume of less than 50 cubic feet per

1,000 BTUH of the aggregate input of all appliances within that space.

The air must be supplied through two permanent openings of equal area. One is

to be located within 12” above the oor and the other is to be located within 12”

below the ceiling.

The minimum net free area of each opening must not be less than one

square inch per 1,000 BTUH of the total input rating of all the appliances in the

enclosure (but not less than 100 square inches), if each opening communicates

with other unconned areas inside the building.

Buildings of unusually tight construction shall have the combustion and

ventilation air supplied from outdoors, or a freely ventilated attic or crawl space.

If air is supplied from outdoors, directly or through vertical ducts, there must be

two openings located as specied above and each must have a minimum net free

area of not less than one square inch per 4,000

BTUH of the total input rating of all the appliances in the enclosure.

If horizontal ducts are used to communicate with the outdoors, each opening must have a minimum net

free area of not less than one square inch per 2,000 BTUH of the total input rating of all the appliances in the

enclosure. If ducts are used, the minimum dimensions of rectangular air ducts shall not be less than 4”

Inspect Shipment

Inspect the water heater for possible damage. Check the markings on the rating plate of the water

heater to be certain the type of gas supplied corresponds to the water heater requirements. Verify

all included parts are present (see below).

NOTICE: If the water heater is installed in an unconned space within a building of

conventional frame, masonry or metal construction, inltration air is normally adequate

for proper combustion and ventilation. If the water heater is installed in a conned space,

provisions for combustion and ventilation air must be made.

NOTICE: If the duct openings which supply combustion and ventilation air are to be covered

with a protective screen or grill, the net free area (openings in the material) of the covering

material must be used in determining the size of the openings. Protective screening for the

openings MUST NOT be smaller than 1/4” esh to prevent clogging by lint or other debris. .

Corrosive Atmospheres

The air in beauty shops, dry cleaning

establishments, photo processing labs, and

storage areas for liquid and powdered bleaches

or swimming pool chemicals often contain such

halogenated hydrocarbons.

An air supply containing halogenated

hydrocarbons may be safe to breathe, but when

it passes through a gas ame corrosive elements

are released that will shorten the life of any gas

burning appliance.

Propellants from common spray cans or gas

leaks from A/ C and refrigeration equipment are

highly corrosive after passing through a ame.

The water heater warranty is voided when failure

of the heater is due to operation in a corrosive

atmosphere.

NOTICE: The water heater should not be

installed near an any air supply containing

halogenated hydrocarbons.

Water Supply Connections....

To conserve energy and to prevent freezing, insulate both cold

and hot water supply lines. DO NOT cover the drain valves.

Install a shuto valve near the inlet of the water heater for service

and draining purposes. Before connecting the water supply pipe to

the water heater, open the shuto valve ·and clean out sand, debris,

air, caulking material, etc. inside the pipe. Connect to the water

inlet, then check water ow. Close the shuto valve and clean the

water lter.

If a water heater is installed in a closed water supply system, such

as one having a backow preventer in the cold water supply line,

means shall be provided to control thermal expansion. Contact

the water supplier or local plumbing inspector on how to control

this situation.

CAUTION: This water heater must only be used with the following water supply system conditions:

• With clean, potable water free of corrosive chemicals, sand, dirt, or other contaminates.

• With inlet water temperatures above 32°F, but not to exceed 90°F.

• Free of lime and scale deposits.

• DO NOT reverse the hot and cold water connections. The water heater will not operate.

To ensure proper operation of the water heater, the following water pressure guidelines should

be followed:

• Operation of the water heater requires the minimum water pressure of 14 psi and a minimum

water ow rate of 0.75 gpm.

• Additional water pressure is required for long pipe runs and outlet tting(s) water pressure

drops.

• To maintain proper performance, ensure sucient water supply pressure. The Required

Water Pressure = Min. Operating Water Pressure (14 psi) + Pipe Pressure Loss + Faucet and

Shower Pressure Loss + Safety Margin (more than 5 psi).

• To supply hot water to upper oors, additional water pressure (0.44 psi/ft) must be ensured.

The measurement should be calculated by the distance between the water inlet of the water

heater (ground level) to the hot water faucet (upper oor level).

• Well water systems should be set at a range of 50-60 psi.

• When the water is supplied from a water supply tank, the height of the tank and the diameter

of the pipes and their relation to water pressure, should be taken into consideration. Gravity

water pressure is not recommended.

IMPORTANT: Do not apply heat to the HOT or COLD water connections. Any heat applied to the

water supply ttings will permanently damage the internal components of the water heater.

NOTICE: If the water ow resistance of a shower head is too high, the burner in the water heater will

fail to ignite. Keep the shower head clean from debris that could cause additional pressure drop.

Notice: If using mixing valves on the outlet, choose one which prevents cold water pressure from

overcoming hot water line pressure.

DO NOT use pipes with smaller diameters than the water supply connection of the water heater.

Be sure to connect the water inlet and the hot water outlet as shown on the water heater. If reversed,

the water heater will not function.

Installation of unions or exible copper connections are recommended on the HOT and COLD water

lines, so that the water heater may disconnect easily for servicing if necessary.

Plumbing should be carried out by a qualied plumber in accordance with local codes. Use approved

plumbing materials and tools only.

Install a Check Valve between the water heater and the water shuto valve. (See illustration below).

In regards to the HOT WATER OUTLET:

• Connections between the water heater and point(s) of use

should be as short and direct as possible.

• DO NOT use lead or non-approved plastic pipe.

• To conserve energy and minimize heat loss, insulation of hot

water piping is recommended.

NOTICE: The ow rate of hot water may vary when more

than two faucets (appliances, xtures, etc.) are being used

simultaneously.

NOTICE: The pipes MUST be completely drainable. If the hot

water faucets are located at a point higher than the water heater,

place a drain valve at the lowest point (see diagram to the left).

Pressure Testing the Gas Supply System

WARNING: Install a gas pressure regulator, in the gas supply line, which does not

exceed the maximum supply pressure. DO NOT use an industrial type gas regulator.

The water heater must be isolated from the gas piping system by closing the manual gas

shut-o valve during any pressure testing of the gas supply piping at pressures equal to or

less than 1/2 psi (14’w.c.) .

High Altitude

Ratings of gas appliances are based on sea level operation and need not be changed for installations

at elevations up to 2,000 feet. Unit not recommended for elevations in excess of 2,000 feet

Leak Testing

EL22-I

A new pressure relief valve, complying with the Standard for relief Valves and Automatic Gas Shut-O

Devices for Hot Water Supply Systems, ANSI Z21.22, must be installed at the hot water outlet connection of

the water heater at the time of installation. Local codes shall govern the installation of relief valves.

For safe operation of the water heater, be sure that:

• The pressure rating of the relief valve must not exceed 150 psi, the maximum working pressure of

the water heater as marked on the rating plate.

• The BTUH rating of the relief valve must equal or exceed the BTUH input of the water heater as

marked on its rating plate.

• No valve of any type should be installed between the relief valve and the water heater.

• Discharge from the relief valve should be piped to a suitable drain to eliminate potential water

damage. Piping used should be of a type approved for the distribution of hot water.

• Hot and cold water lines should be insulated up to the water heater.

• The discharge line must be NO SMALLER than the outlet of the valve and must pitch downward to

allow complete drainage (by gravity) of the relief valve and discharge line.

• The end of the discharge line should not be threaded or concealed and should be protected from

freezing. No valve of any type, restriction or reducer coupling should be installed in discharge line.

NOTICE: The diagram below illustrates a pressure only relief valve. If local codes require a combination

temperature and pressure relief valve be installed, an extension piece may be needed.

Relief Valve

NOTICE: Local codes govern the installation of relief valves. If

local codes require that a temperature and pressure relief valve

should be installed the manufacturer recommends a type 40XL

Watts T&P relief valve or an equivalent model be used.

NOTICE: Manual operation of relief valves should be

performed at least once a year. Turn o the electrical power

and gas shuto valve. Lift and release lever on the relief valve

and check the manual operation of the relief valve. You should

take precaution to avoid contact with the hot water coming out

of the relief valve and to prevent water damage.

NOTICE: If the relief valve on the system discharges periodically,

this may be due to thermal expansion in a closed water supply

system. Contact the water supplier or local plumbing inspector

on how to correct this situation. Do not plug the relief valve.

Venting Lengths

MAXIMUM VENT LENGTH

Owner must refer to vent manufacturer’s instructions and specications. Z-Flex information can be

found at www.novaex.com, please refer to page 19 for additional links.

The system will not operate if there is excessive restriction

(pressure drop) in the venting system. A maximum of 32 feet of

vent pipe may be used provided there is only one 90° elbow in

the system. If additional elbows are required: two elbows can be

used with 27 feet, and three elbows can be used with 22 feet of

vent pipe.

A 90° elbow is equivalent to 5 feet of straight pipe. A 45° elbow

is equivalent to 2 feet 6 inches of straight pipe .

The termination elbow does not count as an elbow when

determining total vent lengths.

The vent must be installed with a slight downward slope of 1/ 4”

per foot of horizontal run toward the vent terminal (see diagram

below). This ensures that any condensate formed during

operation of the unit is evacuated from the water heater.

A 1/4” per foot upward slope is acceptable when it is not

possible to vent with a downward slope, however, a UL approved

Category III Stainless Steel condensate trap MUST be installed

at the beginning of the horizontal run (See page 20 “Typical

Horizontal Termination w/ 1/4” per foot UPWARD Slope” or

page 14, “Standard Vertical Vent Termination” for examples).

in the installation, and the wall

thimble is installed.

NOTICE: Make sure that the seam

of the vent pipe in horizontal runs

is toward the top of the installation

(see illustration to the left)

Draining the Condensate

In certain conditions, installations in unconditioned space or having long horizontal or vertical

runs may accumulate condensate.

Condensate is known to be acidic; refer to local, state (provincial) or federal codes for proper

handling methods.

In order to prevent condensate from draining back into the water heater, we recommend a

condensate trap and drain to be installed in a horizontal vent section as close as practical to

the water heater vent connection.

Not following proper condensate procedures will void warranty.
