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 different 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 appliances 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 sniff 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 appliance.

• 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.

Installing the water heater

Indoor Location

• Installation distances may vary by local code. It is the installer’s responsibility to verify

installation requirements.

• Make sure before installation that the gas type you will use is the same type on the data plate.

• The water heater unit should be installed by professionals. Improper installation may cause

failure or dangerous conditions such as gas leaking or explosion.

• Water Heater cannot be installed in an UN-VENTED bathroom, bedroom, basement, living room,
closet, outdoor, stairway or an exit area. If installed in an exit area, it must be at least 16.5 ft. or

more away from the exit.

• Vent pipe should extend from the wall at least 2”. The terminal must be at least 1.64 ft. away

from obstruction, and must be well vented.

• Vent pipe should slope 3° downward, to avoid condensing water and protect from rain entering.

• Vent pipe should avoid direct, strong wind because the downdraft will cause malfunction.

• The unit should be installed far from any blockage, and with plenty of enough space for

installation and maintenance. Adequate clearances for servicing must be provided.

• The unit should not be installed in the same room with a gas stove .

• When determining the oor clearance, a clearance of 6 inches must be maintained between the

vent pipe and combustible material. A side wall clearance of 6 inches and a top clearance of 12
inches must be maintained.

• The vent pipe can be up to 32 ft. in length with one elbow.

• The vent pipe should be installed with a ame retardant wall thimble. Owner must refer to vent

manufacturer’s instructions and specications.

• The power socket connecting the water heater should be grounded properly with a GFCI circuit
protector.

• The water heater should not be located in an area where leakage of the heat exchanger or
connections will result in damage to the area adjacent to it or to lower oors of the structure.
When such areas cannot be avoided it is recommended that a suitable catch pan, adequately
drained, must be installed under the water heater. The pan must not restrict combustion
airow.

• The water heater should be installed as close as practical to the vent termination to minimize
vent length and the number of elbows required for venting.

• A gas red water heater or any other appliance should not be installed in a space where liquids
which give off ammable vapors are to be used or stored. Such liquids include gasoline, LP gas
(butane or propane), paint or adhesives and their thinners, solvents or removers.

• The unit should be installed far from heat sources, ammable and dangerous materials.
Because of natural air movement in a room or other enclosed space, ammable vapors can
be carried some distance from where their liquids are being used or stored. The open ame of
the water heater’s main burner can ignite these vapors causing an explosion or re which may
result in severe burns, death or property damage.

Installing the water heater continued....

• Raising the water heater will reduce, BUT NOT eliminate the possibility of lighting the vapor of
any ammable liquids which may be improperly stored or accidentally spilled .

• If the water heater is installed in a garage, it should be installed so that the direct ignition
system and main burner are no less than 18 inches above the garage oor.

• Hot and cold water lines should be insulated to conserve water and energy.

• The water heater must be located so it is not subject to physical damage, for example, by

moving vehicles, area ooding, etc.

• The water heater should be installed with the proper venting materials and termination suitable
for Category III venting. Failure to install and properly vent the water heater to the outdoors as
outlined in the Venting Section of this manual can result in unsafe operation. Owner must refer
to vent manufacturer’s instructions and specications.

• For other than a direct vent appliance, the appliance must be located as close as practicable to a
chimney or gas vent.

• DO NOT install water heater where subject to vibrations or on the road use.

• DO NOT install the water heater in Recreational Vehicles, Mobile Homes, Boats and other
Watercraft.

• DO NOT install the water heater near vents for heating or cooling. A minimum of 4 feet should

Installing the water heater continued....

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

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

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.

must be two openings located as specied above and each must have a minimum

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”

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.

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).

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.

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

To conserve energy and to prevent freezing, insulate both cold and hot
water supply lines. DO NOT cover the drain valves. Install a shutoff
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 shutoff valve ·and clean out sand, debris, air, caulking
material, etc. inside the pipe. Connect to the water inlet, then check

water ow. Close the shutoff 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 suf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.

10

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.

• 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).

Relief Valve

A new pressure relief valve, complying with the Standard for relief Valves and Automatic Gas Shut­Off 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.

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 off the electrical power
and gas shutoff 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

Venting

The installation of venting must
comply with national codes, local
codes, and the vent manufacturer’s
instructions.

The water heater must be vented
to the outdoors as described
in these instructions. DO NOT
connect this water heater to an
existing Vent or Chimney, it must
be vented separately from all other
appliances.

All vent components (adapters,

pipe, elbows, terminals, etc.) should

be UL 1738 Certied Stainless Steel
Venting Material (e.g. AL29-4C).

The specied vent termination

must be used. The termination
should be a 90° elbow type with

screen. (Refer to page 19).

Use a vent pipe with an anti­disconnection structure.

The use of a High Temperature

Silicone (500’ F) may be required

to seal vent connections. To
prevent accidental gas exhaust

leakage, apply a 1/4” wide bead
approximately 1/4” from the end

and another bead against the joint
side of the stop bead.

Follow vent manufacturer’s
installation instructions.

The unit can be vented either
horizontally or vertically.

Vent pipe runs must be adequately
supported along both horizontal
and vertical runs.

The maximum recommended
unsupported span should be no

more than ve (5) feet. Support

isolation hanging bands should
be used. DO NOT use wire. (See
diagram below).

WARNING:

Refer to pages 17-

18 for clearances to

combustible material.

Venting Through Closed Spaces

If the vent piping passes through a closed space, wrap the vent pipe with inammable insulation material
that is at least 3/4” thick. DO NOT let the insulation material make contact with ammable materials. A
minimum clearance of 6” between the vent pipe and ceiling should be maintained. Follow local codes.

For maintenance and inspection purposes, the following holes are required to be made:

• Two (2) inspection openings that allow access to venting. One

(1) of these openings should be close to where the vent pipe

enters the ceiling. The other opening should be near the vent
termination.

• A ventilation hole with a 16 sq. in. opening should be made at
least every 10 feet.

NOTICE: Vent pipes must be completely insulated with

inammable material when installed in alcoves, closets, and

garages and must not touch any ammable material.

22’

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 appliance

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).

MINIMUM VENT LENGTH

The venting may be as short as 12”,

provided one vent termination is
installed to the outdoors through a
sidewall, one 90°elbow is included in

12 in. minimum

the installation, and the wall thimble
is installed.

16

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.

Set Temperature Memory:

• This water heater contains an electronically controlled
thermostat. From the factory, the temperature range
is between 90°F and 140°F.

• The remote control is factory preset to 110°F.

• To turn the remote control ON or OFF, press the
POWER button for more than 3 seconds.

• To adjust the temperature to a required setting,

in“priority” mode, press the UP or DOWN temperature

button. Press and hold UP or DOWN to raise or lower
the temperature continuously.

• When the unit is in use, the set temperature can
increase to 122°F, but there is no limit to temperature
decrease. To increase the temperature more than

122°F, the water will need to be shut off rst.

NOTICE: If inlet water temperature is high, and set temperature
is low, the actual temperature might be higher than the set
temperature, and vice versa..

Safety factors should be considered when selecting
the water temperature setting of the water heater’s
remote control. The remote control was set at 110°F
before the water heater was shipped from the factory.
This is the recommended starting point.

Water temperatures above 120°F can cause severe
burns or death from scalding. The thermostat is
adjusted to its lowest temperature position when
shipped from the factory.

Be sure to read and follow the warnings outlined in this
manual and on the label located on the water heater.
Mixing valves are available for reducing point of use
water temperature by mixing hot and cold water in
branch water lines.

Procedures for adjusting the thermostat for energy
efcient operation at the minimum water temperature
setting consistent with the consumer’s needs.

Contact a licensed plumber or the local plumbing
authority for further information. See page 4 for

details.

• The display will read the set temperature if the water

heater is not in use or there is no water ow. If the
water heater is in use or has water ow, the display

will read the actual temperature. To view the set
temperature in this condition, press UP or DOWN and

the set temperature will ash for 3 seconds.

• The hottest temperature water will be at the hot water
faucet closest to the water heater

• Always remember to test the water temperature with
your hand before use and remember that hotter water
increases the risk of scald injury.

• Always supervise young children or others who are
incapacitated.

• If the water heater has been subjected to re, ood
or physical damage, turn off the manual gas shut-off

valve(s), and do not operate the water heater again

Care and cleaning of the water heater.

Routine Preventative Maintenance

DANGER: Before

manually operating
the relief valve, make

certain no one will

be exposed to the
danger of the hot
water released by
the valve. The water
may be hot enough to
create a scald hazard.
The water should be
released into a suitable
drain to prevent injury
or property damage.

DANGER: Hotter
water increases the

potential for Hot Water

Scalds.

DANGER: Failure

to perform the

recommended

Routine Preventative

Maintenance can harm

the proper operation

of this water heater,
which can cause

carbon monoxide
dangers, excessive hot
water temperatures
and other potentially
hazardous conditions.

Properly maintained, your water
heater will provide years of
dependable trouble-free service.
It is recommended that a periodic
inspection of the burner, relief

valve, water lter and venting

system should be made by service

valves in automatic water using
appliances can cause a banging
noise heard in a water pipe.
Strategically located risers in
the water pipe system or water
hammer arresting devices can be
used to minimize the problem.

Inspect the area around the
water heater to ensure a safe
operating environment. Keep
appliance area clear and free from
combustible materials, gasoline,

and other ammable vapors

and liquids. Ensure the unit has
not been damaged. If damage
or denting is present, contact a
service personnel to verify proper
operation.

Check for any abnormal sounds
during normal operation of the
water heater.

All piping should be checked for gas
and/or water leaks. Refer to page
12 of this manual for instructions
on leak testing.
