SECTION III: PRE-INSTALLATION
LOCATION
CAUTION
This water heater must be located in an area where leakage of the tank, water line
connections, or the 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
location 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. The
drain pan can be purchased from your plumbing professional. The drain pan must be
piped to an adequate drain and all drain piping must be at least 0.75” in diameter
and pitched for proper drainage.
CAUTION
DO NOT store or use gasoline or other flammable, combustible, or corrosive vapors
and/or liquids in the vicinity of the water heater or any other appliance.
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 your
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!
CAUTION
Do not drop water heater or lay heater down on its side. Move the water heater into
position by sliding or using an appropriately sized hand truck.
The solar indirect water heater must be installed indoors. Locate the water heater as close as
practical to the solar heating system and leave sufficient clearances for servicing the heater.
The entire solar heating system should be located as close as possible to points of hot water
use for the fastest delivery of hot water. This water heater may be installed on combustible
flooring. DO NOT install this water heater on carpeting.
See Tables 4 and 5 for combustible and service clearances.
