The location of this water heater is of the utmost importance. Before installing this water heater, you should read the
Installation section of these instructions. After reading these Installation and Operating Instructions, select a location for
the water heater where the floor is level and is easily accessible to water lines, gas supply (type identified on the rating
plate), an adequate open drain, and within the maximum specified venting distance to an outside wall or roof for the direct
vent terminal. DO NOT locate the water heater where water lines could be subjected to freezing temperatures.
Make sure the cold water pipes are not located directly above the gas control so that condensate during humid
weather does not drip or accumulate on the controls.
This installation must allow access to the front of the water heater and adequate clearance must be provided for servicing
and operating this water heater. The water heater may be installed on either a combustible or non-combustible floor. If
the water heater is to be installed directly on carpeting, it must be installed on top of a metal or wood panel (or equivalent)
extending beyond the full width and depth of the appliance by at least three (3) inches (7.6 cm) in any direction or, if the
appliance is to be installed in an alcove or closet, the entire floor must be covered by the panel. The panel must be
strong enough to support the weight of the water heater when full of water.
This water heater MUST be installed indoors out of the wind and weather.
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.
Water heater corrosion and component failure can be caused by the heating and breakdown of airborne chemical
vapors. Examples of some typical compounds that are potentially corrosive are: spray can propellants, cleaning solvents,
refrigerator and air conditioning refrigerants, swimming pool chemicals, calcium and sodium chloride, waxes and process
chemicals. These materials are corrosive at very low concentration levels with little or no odor to reveal their presence.
UNPACKING
INSPECT SHIPMENT carefully for any signs of damage.
1. All equipment is carefully manufactured, inspected and packed.
2. Any claims for damage or shortage in shipment must be filed immediately with the manufacturer noted on the
rating plate label.
LOCATE WATER HEATER in front of final position before removing crate.
1. LOCATE so that venting connections will be short and direct.
2. THIS WATER HEATER IS SUITABLE FOR INSTALLATION ON COMBUSTIBLE FLOOR. The thermal break
leg kit supplied with the water heater must be used.
3. Proper venting practices must be considered when selecting a location for this water heater. For exact venting
specifications, please consult the Venting section of these Installation and Operating Instructions.
4. It is recommended that a minimum clearance of four (4) inches (10.2 cm) be provided on the side of the water
heater for servicing and maintenance of the combination temperature and pressure relief valve.
DAMAGE TO THE WATER HEATER CAUSED BY EXPOSURE TO CORROSIVE VAPORS IS NOT COVERED
BY THE WARRANTY. DO NOT OPERATE THE WATER HEATER IF EXPOSURE HAS OR WILL OCCUR. DO
NOT STORE ANY POTENTIALLY CORROSIVE COMPOUNDS IN THE VICINITY OF THE WATER HEATER OR
THE DIRECT VENT TERMINAL.
In order to provide clearance for the burner panel access screws to be removed, use a slab inside the drain pan to
raise the water heater 1” (2.5 cm) so that the burner access panel clears the lip of the drain pan. There must be
access to the burner assembly for servicing. Be sure the water heater remains level.
This water heater may be installed in an alcove on combustible flooring with clearances from combustible materials
as shown in the following clearances illustration of this Installation and Operation Instruction Manual.
NOTICE
IF COMBUSTIBLE FLOORING IS USED, A THERMAL BREAK LEG KIT MUST BE INSTALLED BEFORE
SETTING WATER HEATER IN PLACE. THE APPROPRIATE LEG KIT HAS BEEN INCLUDED WITH THIS
WATER HEATER.
