Installation (Locating the Water Heater) continued-
The water heater must be located close enough to the outside wall to keep the venting
distance within the maximum distance described in the installation instructions. Locate
the water heater as close as possible to the vent opening. Read the venting section in
this instruction manual before locating the water heater.
This water heater must be located in an area where leakage of the tank, condensate
trap, or water line connections and 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. Verify all condensate tubing is properly connected to the blower for
proper drainage. When such locations cannot be avoided, a suitable drain pan
adequately piped for proper drainage must be installed under the water heater. The pan
must not restrict combustion air flow. The drain pan must have a minimum length and
width of at least 4 in. (10.2 cm) greater than the diameter of the water heater and must
not restrict proper combustion air flow to the water heater. The drain pan, as described
above, can be purchased from your plumbing professional. The drain pan must be piped
to an adequate drain. The piping must be at least 3/4 in. (1.9 cm) in diameter and
pitched for proper drainage.
It is recommended that a minimum clearance of 4 in. (10.2 cm) be provided on the side
of the water heater for servicing and maintenance of the combination temperature and
pressure relief valve.
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, Sacramento, CA 95811.
Minimum Clearances
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 extending beyond the full width and depth of the appliance by
at least 3 in. (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 minimum
clearances to combustibles for this water heater are: 0 in. from the sides and rear, 5
in. (12.7 cm) from the front of the jacket, 0 in. from the vent connector and 15 in.
(38.1 cm) from the jacket top. Increase distances to provide clearance for servicing.
WARNING
Failure to adhere to these installation and operation instructions
may create a hazard to life and property and will nullify the warranty.
IMPORTANT
This water heater can be installed as either power direct vent or power vent
(air from inside) system. If it is installed as a direct vent system, then the air
intake and the exhaust vent are piped to the outside. If a power vented system
is used, then air is drawn from inside and only the exhaust is piped to the
outside. Horizontal and vertical venting can be mixed. Determine which system
is best for your application and install as described in the following sections.
