Safety and energy conservation are factors to be considered when selecting the water
temperature setting of a water heater’s gas control. Water temperatures above 125°F
can cause severe burns or death from scalding. Be sure to read and follow the warnings
outlined on the label pictured below. This label is also located on the water heater.
Notice: Mixing valves are available for reducing
point of use water temperature by mixing hot and
cold water in branch water lines. Contact a licensed
plumber or the local plumbing authority for further

DANGER: Hotter
water increases the
potential for Hot Water
SCALDS.
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.


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. LP for LP units. 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.
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
& 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.
!
DANGER: 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.

California Law requires that residential water heaters must be braced, anchored or
strapped to resist falling or horizontal displacement due to earthquake motions. For
residential water heaters up to 52-gallon capacity, a brochure with generic earthquake
bracing instructions can be obtained from: Office of the State Architect, 1102 Q Street,
Suite 5100, Sacramento, CA 95814 or you may call 916-445-8100 or ask a water heater
dealer.
However, applicable local codes shall govern installation. For residential water heaters
of a capacity greater than 52 gallons, consult the local building jurisdiction for acceptable
bracing procedures.

Installing the water heater.
Combustion and Ventilation Air
Ventilation (ambient) air temperature
must be 100°F or less. 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.
DO NOT block or obstruct any of the
combustion air inlet openings located
around the perimeter of the water
heater. A minimum of 1” is required
between these combustion air inlet
openings and any obstruction.
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.

DANGER: Failure to
install the blower assembly
and properly vent the water
heater to the outdoors as
outlined in the Venting
section of this manual will
result in unsafe operation of
the water heater causing
bodily injury, explosion,
fire or death.
To avoid the risk of fire,
explosion, or asphyxiation
from carbon monoxide,
NEVER operate the water
heater unless it is properly
vented and has adequate air
supply for proper operation
as outlined in the Venting
section of this manual.
The vent pipe must overlap
a minimum of ½” on each
connection. It is important
that the vent pipe engages
fully into any pipe fitting
and be kept in that position
until the adhesive has fully
cured. DO NOT drill or
punch holes in the plastic
pipe or fittings.
NOTICE: This unit is
equipped with a Flammable
Vapor Sensor. Do not
apply power until enough
time has passed to allow the
vapors from the primer and
cement to dissipate.

WARNINGMoisture in the flue gas will condense as it

freeze on the exterior wall, under the eaves and on
surrounding objects. Some discoloration to the exterior of

NOTICE: Stir the solvent cement
frequently while using. Use a natural
bristle brush or the dauber supplied
with the can. The proper brush size is
one inch.
NOTICE: This unit is equipped with a
Flammable Vapor Sensor. Do not apply
power until enough time has passed to
allow the vapors from the primer and
cement to dissipate.
Cementing Joints
WARNING: DANGER
OF FIRE OR BODILY
INJURY - Solvent cements
and primers are highly
flammable. Provide
adequate ventilation and do
not assemble near heat
source or open flame. Do not
smoke. Avoid skin or eye
contact. Observe all cautions
and warnings on material
containers.
CAUTION:
For proper installation:
DO NOT use solvent cement
that has become curdled,
lumpy or thickened.
DO NOT thin solvent
cement. Observe shelf
precautions printed on the
containers.
For applications below 32°F
use only low temperature
type solvent cement.
Appropriate solvent and
cleaner must be used for the
type of vent pipe used (PVC,
CPVC or ABS).
NOTICE: All pipe, fittings, solvent cement, primers and procedures must conform to American
National Standards Institute and American Society for Testing and Materials (ANSI/ASTM) standards.
