SECTION IV: INSTALLATION INSTRUCTIONS

INSTALLATION OF THIS WATER HEATER SHOULD BE DONE BY A TRAINED AND QUALIFIED PROFESSIONAL.
PLUMBING, AIR SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK ARE REQUIRED.
DO NOT ATTEMPT TO LIGHT ANY GAS APPLIANCE IF YOU ARE NOT CERTAIN OF THE FOLLOWING:
•
Liquefied petroleum gases/propane gas and natural gas have an odorant added by the gas supplier that aids in
detection of the gas.
•
Most people recognize this odor as a "sulfur" or "rotten egg" smell.
•
Other conditions, such as "odorant fade" can cause the odorant to diminish in intensity, or "fade", and not be as
readily detectable.
•
If you have a diminished sense of smell or are in any way unsure of the presence of gas, immediately contact
your gas supplier from a telephone in another building.
•
Gas detectors are available. Contact your gas supplier or plumbing professional for more information.
Liquefied petroleum gases/propane gas is heavier than air and will remain at floor level if there is a leak. Basements,
crawl spaces, closets and areas below ground level will serve as pockets for accumulation of leaking gas. Before lighting,
smell all around the appliance area for gas. Be sure to smell next to the floor.
IF YOU SMELL GAS:
•
DO NOT try to light any appliance.
•
DO NOT touch any electric switch; DO NOT use any telephone in your building.
•
Immediately call your gas supplier from a telephone in another building. Follow the gas supplier's instructions.
•
If you cannot reach your gas supplier, call the fire department.
DO NOT OPERATE THE APPLIANCE UNTIL THE LEAKAGE IS CORRECTED!
This water heater must be located in an area where leakage of the tank, water line connections, or the combination
temperature and pressure relief valve will NOT result in damage to the area adjacent to the water heater or to lower floors
of the structure. When such locations cannot be avoided, a suitable drain pan must be installed under the water heater.
The drain pan depth must be suitable for draining and collecting water and have a minimum diameter of at least
4 in (10.2 cm) measured from the jacket of the water heater. The drain pan can be purchased from your plumbing
professional. The water heater may need to be placed on blocks inside drain pan to fit in a standard size pan. The drain
pan must be piped to an adequate drain. The piping must be at least ¾ inch (2 cm) in diameter and pitched for proper
drainage.
Water heaters are heat producing appliances. To avoid damage or injury there must be no materials stored against the
water heater and proper care must be taken to avoid unnecessary contact (especially by children) with the water heater
components. UNDER NO CIRCUMSTANCES SHOULD FLAMMABLE MATERIALS, SUCH AS GASOLINE OR PAINT
THINNER BE USED OR STORED IN THE VICINITY OF THIS WATER HEATER, VENT-AIR INTAKE SYSTEM OR IN
ANY LOCATION FROM WHICH FUMES COULD REACH THE WATER HEATER OR VENT-AIR INTAKE SYSTEM.
Failure to adhere to these Installation and Operation Instructions may create a hazard to life and property and will nullify
the warranty.
The National Fuel Gas Code (ANSI Z233.1- latest edition) or in Canada The Natural Gas Installation Code
CAN/CGA (B149.1 - latest edition), expressly prohibits the following:
a. Installation of a water heater in a bathroom, bedroom, or any occupied room normally kept closed.
b. Installation of a water heater in a garage, unless the unit is installed so that the burner and ignition devices are at
least 18 in (45.8 cm) above floor level and protected to avoid damage by a moving vehicle.
If the building's cold water supply has a back-flow preventer, check valve, or water meter with check valve, provisions for
thermal expansion of water in the hot water system must be provided.
Note: For California installation this water heater must be braced, anchored, or strapped to avoid falling
or moving during an earthquake. See instructions for correct installation procedures. Instructions may
be obtained from DSA Headquarters Office, 1102 Q Street, Suite 5100, Sacramento, California 95811.
