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.
Notice: If a gas leak is present or suspected:
● Do not attempt to find the cause yourself.
● Do not try to light any appliance.
● 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.
● Do not touch any electrical switch.
● Do not use any phone in your building.
● 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
● Leave the building immediately and make
sure your family and pets leave also.
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.
● Leave the doors open for ventilation and
contact the gas supplier, a qualified service
agency or the fire department.
● Stay away from the building until the
service call has been made, the leak is
corrected and a qualified agency has
determined the area to be safe.
● 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.
● 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.
● It is recommended that more than one
method, such as soapy solution, gas
detectors, etc., be used to detect leaks
in gas applications.

Installing the water heater:
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 (Indoor Water Heater Only)
NOTICE: If the water heater is installed in
an unconfined space within a building of
conventional frame, masonry or metal
construction, infiltration air is normally
adequate for proper combustion and
ventilation. If the water heater is installed in
a confined space, provisions for combustion
and ventilation air must be made.
Buildings of unusually tight construction
shall have the combustion and ventilation
air supplied from outdoors, or a freely
ventilated attic or crawl space.
Air openings
minimum 1 in2
(6.5 cm2) per
1000 Btuh of
total input
If air is supplied from outdoors, directly or
through vertical ducts, there must be two
openings located as specified above and
each must have a minimum net free area
of not less than one square inch
(6.5 sq cm) per 4000 Btuh of the total
input rating of all the appliances in the
enclosure.
A confined space is one having a volume
of less than 50 cubic feet (1.4 cubic
meters) per 1000 Btuh of the aggregate
input of all appliances within that space.
Min. 3”
(7.6 cm)
The air must be supplied through two
permanent openings of equal area. One
is to be located within 12” (30 cm) above
the floor and the other is to be located
within 12” (30 cm) below the ceiling.
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
(6.5 sq cm) per 2000 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 3” (7.6 cm).
DANGER: OUTDOOR
water heaters must not
be installed indoors or
in a confined space.
The minimum net free area of each opening
must not be less than one square inch (6.5
sq cm) per 1000 Btuh of the total input
rating of all the appliances in the
enclosure (but not less than 100 square
inches [650 cm2]) if each opening
communicates with other unconfined areas
inside the building. The above
requirements shall be used unless:
national, provincial, or local codes govern
the requirement for these air openings.
Install outdoor water
heaters outdoors only.
NOTICE: If the duct openings which supply
combustion and ventilation air are to be
covered with a protective screen or grille,
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” (0.64 cm) mesh to
prevent clogging by lint or other debris.
NOTICE: The water heater
should not be installed near
an air supply containing
halogenated hydrocarbons.
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 contains such halogenated
hydrocarbons.
Propellants from common spray cans
or gas leaks from A/C and refrigeration
equipment are highly corrosive after
passing through a flame.
The water heater warranty is voided when
failure of the heater is due to operation in
a corrosive atmosphere.
An air supply containing halogenated
hydrocarbons may be safe to breathe,
but when it passes through a gas flame,
corrosive elements are released that
will shorten the life of any gas burning
appliance.
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).

● To supply hot water to upper floors,
additional water pressure (0.44 psi/ft
[10 kPa/m]) must be ensured. The
measurement should be calculated by the
distance between the water inlet of the
water heater (ground level) to the hot

To ensure proper operation of the water
heater, the following water pressure guidelines
should be followed:
● Well water systems should be set to ensure
a minimum system pressure of 40 psi (276
kPa). The pressure should remain stable
during the operation of the water heater.
● Operation of the water heater requires the
minimum water pressure of 14 psi (97 kPa)
and a minimum water flow rate of 0.66
gpm (2.5 lpm).
● When the water is supplied from a water
supply tank, the height of the tank and the

water pressure should be taken into
consideration. Gravity water pressure is
not recommended.
● A water pressure of 40 psi (276 kPa) is

Water Temperature Setting…
Maximum water temperature occurs while
the burner is on. To determine the water
temperature, turn on a hot water faucet and
place a thermometer in the water stream.
Water temperature at the faucet may vary
depending on season and length of pipe
from the water heater.
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.
The factory setting of the remote control
temperature range is between 100°F (38°C)
and 120°F (49°C).
The water heater is equipped with a device
that will shut off the gas supply to the burner
if the water heater exceeds normal operating
temperatures. Refer to the “Before You Call
