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. Read the venting section in this installation instruction manual
before locating the water heater.
This water heater must be located in an area where leakage of the tank 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. 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 inch (1.9 cm) in diameter and pitched for
proper drainage.
It is recommended that a minimum clearance of 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.
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.
WARNING
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 the 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
neighbor’s telephone.

Gas detectors are available. Contact your gas supplier, or plumbing
professional, for more information.
