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 camouflage 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 fire, 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 certified 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 first 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 fittings 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 floor 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 find 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
qualified service agency or the fire department.
• Stay away from the house (or building) until the service call has been
made, the leak is corrected and a qualified agency has determined the
area to be safe.

• 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 flow 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 fittings will permanently
damage the internal components of the water
heater.
Water Supply Connections
Plumbing should be carried out by a qualified
plumber in accordance with local codes.

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 flow rate of 0.75 gpm.
• Additional water pressure is required for
long pipe runs and outlet fitting(s) water
pressure drops.
• To maintain proper performance, ensure
sufficient 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 floors,
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 floor level).
• Well water systems should be set at a
range of 50-60 psi.

shutoff
valve. (See illustration to the top left).
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.
NOTICE: The flow rate of hot water may vary when more than two
faucets (appliances, fixtures, 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 illustration to the bottom left).
Gas Supply
WARNING: Do not attempt to convert this water heater for use with a different type of gas
other than the type shown on the rating plate. Such conversion could result in hazardous operating
conditions. Please have a professional connect the gas pipe.
A Manual Gas Appliance Shutoff
Valve must be installed at the gas
connection of the water heater at the
time of installation (see diagram to
the left). The branch gas supply line to
the water heater should be clean black
steel pipe or other approved gas piping
material.
A ground joint union or ANSI design
certified semi-rigid or flexible gas
appliance connector should be
installed in the gas line close to the
water heater. The National Fuel Gas
Code (NFGC) mandates a manual gas
shut-off valve: See (NFGC) for complete
instructions.
If flexible connectors are used, the
maximum length shall not exceed 36”.
If lever type gas shut offs are used,
they shall be T-Handle type.
Compound used on the threaded
joints of the gas piping must be of
the type resistant to the action of LP
gas. Use compound sparingly on male
threads only.
A sediment trap should be installed
at the bottom of the gas line.
Do not use excessive force (over
31.5 ft lbs.) in tightening the pipe,
particularly if pipe-tape compound
is used, as the unit may be damaged.
The inlet gas pressure to the water
heater must not exceed 10.5 “ w.c.
for natural or 14” w.c. for LP gas. For
purposes of input adjustment, the

• 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 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 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-Off 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.

(see illustration):
• Twelve (12) inches above grade level and above normal snow levels.
• Four (4) feet below, or four (4) feet horizontally from any door,
window, soffit, under eave vent or gravity air inlet to the building
or other appliances, or from gas or electric meters. Do not locate
vent above walkways, doors, windows, air inlets, gas or electric
meters or other equipment.
• Ten (10) feet from any forced air inlet to the building. Any fresh or
make-up air inlet such as for a dryer or furnace area
is considered to be a forced air inlet.
• Eighteen (18) inches from an inside corner formed by two exterior walls.
• DO NOT install vent terminal under any patio or deck.
• To help prevent moisture from freezing on walls and under eaves,
do not locate vent terminal on the side of a building
with prevailing winter winds.
• DO NOT locate vent terminal too close to shrubbery, as flue
gases may damage them.
• Caulk all cracks, seams and joints within six (6) feet of vent terminal.
• All painted surfaces should be primed to lessen the chance of
physical damage. Painted surfaces will require maintenance.
Additional Considerations
WARNING : Moisture in the flue gas will condense as it leaves the vent terminal. In cold weather
this condensate can freeze on the exterior wall, under the eaves and on surrounding objects.
Some discoloration to the exterior of the building is to be expected. However, improper location
or installation can result in severe damage to the structure or exterior finish of the building. Code
requirements are subject to change and may vary by location.
