Qualified Installers Only!
Be sure to read and understand the entire Use and Care Manual before attempting to install or operate this
water heater. It may save you time and money. Pay particular attention to the Safety Instructions. Failure to
follow these warnings could result in serious bodily injury or death. Should you have problems understanding
the instructions in this manual, or have any questions, STOP, and get help from a qualified service technician,
or the local gas utility.
Failure to install and properly vent the water heater to the outdoors as outlined in the
Venting Section of the Installation Instructions in this manual can result in unsafe operation
of the water heater. To avoid the risk of fire, explosion or asphyxiation from carbon
monoxide, never operate this water heater unless it is properly vented and has an adequate
air supply for proper operation.
Be sure to inspect the vent outlet for proper installation at initial start-up; and at least
annually thereafter. Refer to the Care and Cleaning section of this manual for more
information regarding vent system inspection.
Gasoline, as well as other flammable materials and liquids ( which include, but are not
limited to adhesives, solvents, paint thinners etc.), and the vapors they produce are
extremely dangerous. DO NOT handle, use or store gasoline or other flammable or
combustible materials anywhere near or in the vicinity of a water heater or any other
appliance. Be sure to read and follow the labels on the water heater, as well as the warnings
printed in this manual. Failure to do so can result in property damage, bodily injury or
death.
DANGER
FLAMMABLES
Flammable Vapors
Water heater has a main
burner flame.
The main burner flame:
1. which can come on
at any time and
2. will ignite flammable
vapors.
Vapors:
1. cannot be seen,
2. are heavier than air,
3. go a long way on the
floor and
4. can be carried from
other rooms to the
main burner flame by
air currents.
Vapors from flammable
liquids will explode and
catch fire causing death or
severe burns.
Do not use or store flammable
products such as gasoline,
solvents or adhesives in the
same room or area near the
water heater.
Keep flammable products:
1. far away from heater,
2. in approved containers,
3. tightly closed and
4. out of children's reach.
Installation:
Do not install water heater
where flammable products will
be stored or used unless the
main burner flame is at least
18" above the floor. This will
reduce, but not eliminate, the
risk of vapors being ignited
by the main burner flame.
Read and follow water heater warnings and instructions. If
owners manual is missing, contact the retailer or manufacturer.

HOT
Water temperature over 125°F can
cause severe burns instantly or
death from scalds.
Children, disabled and elderly are
at highest risk of being scalded.

setting temperature at water
heater.
Feel water before bathing or
showering.
Temperature limiting valves are
available, see manual.

Safety and energy conservation are factors to be considered when selecting the water
temperature setting of a water heater’s remote control. Water temperatures above
125°F (52°C) can cause severe burns or death from scalding. Be sure to read and follow

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.
● 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.
● 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.
Notice: If a gas leak is present or suspected:
● Donotattempt to find the cause yourself.
● Donot try to light any appliance.
● Donot touch any electrical switch.
● Donot use any phone in your building.
● Leave the building 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 building until the
service call has been made, the leak is
corrected and a qualified agency has
determined the area to be safe.
!
For your safety, the information in this manual must be followed to minimize the risk
of fire or explosion, electric shock, or to prevent property damage, personal injury or
loss of life.
California Law requires that water heaters must be braced, anchored or strapped to resist
falling or horizontal displacement due to earthquake motions. For 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 or tankless-style, consult the local building jurisdiction
code for acceptable bracing procedures.
Have the installer show you the location of the gas shut-off valve and how to shut it off
if necessary. Turn off the manual shut-off valve if the water heater has been subjected
to overheating, fire, flood, physical damage or if the gas supply fails to shut off.
● Read this manual entirely before installing
or operating the water heater.
● Use this appliance only for its intended
purpose as described in this Use and Care
Manual.
● Be sure your appliance is properly installed
in accordance with local codes and the
provided installation instructions.
● Do not attempt to repair or replace any
part of your water heater unless it is
specifically recommended in this manual.
All other servicing should be referred to a
qualified technician.
Installing the water heater:
This water heater must be installed in accordance with these instructions, local codes, utility company
requirements and/or in the absence of local codes, use the latest edition of the American National Standard/
National Fuel Gas Code. A copy can be purchased from either the American Gas Association, 400 North
Capitol Street Northwest, Washington, DC 20001 as ANSI standard Z223.1 or National Fire Protection
Association, 1 Batterymarch Park, Quincy, MA 02269 as NFPA 54. In Canada, the latest edition of the CSA
B149.1 Natural Gas and Propane Installation, and the Canadian Electrical Code, CSA C22.1 Part 1, in the
absence of local codes.
Location of the water heater
This water heater is for OUTDOOR
installation ONLY!
This water heater is an outdoor model
and must be mounted vertically. It
must not be installed indoors or in an
enclosure.
The water heater should be installed
close to the most frequently used outlet
and its position chosen with safety and
service in mind.
Make sure people (particular children,
disabled, and elderly) will not touch the
hot water outlet or the flue terminal.
The flue terminal and air inlet must be
clear of obstruction and shrubbery.
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 floors of the structure.
