SECTION III: PRE-INSTALLATION (cont .)
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.
CAUTION
If the water heater is installed directly on carpeting, the water heater shall be installed
on a metal or wood panel extending beyond the full width and depth of the water
heater by at least 3 inches (76.2 mm) in any direction or, if the water heater is installed
in an alcove or closet, the entire floor shall be covered by the panel. The panel must be
strong enough to carry the weight of the heater when full of water.
NOTE: Locate the heater so it is not subject to physical damage from moving vehicles or
flooding. Do not locate the water heater in a room where swimming pool chemicals or large
quantities of water softener salt are kept. Installing a water heater in this environment will
result in premature failure of tank and burner components due to corrosion caused by these
elements diffusing into the air.
The water heater can be installed on combustible or non-combustible flooring. Maintain
clearances specified in this manual and in accordance with the National Fuel Gas Code (NFPA
54, ANSI Z223.1) unless otherwise directed by state and local code requirements. Locate the
water heater such that plastic vent pipe lengths and the number of connection fittings are
minimized.
Minimum clearances from combustible construction are:
Table 3: Clearances
1) Measured from water heater jacket to wall. This clearance accommodates the air intake
boot.
2) Measured from jacket to closet door.
3) Measured from water heater top to ceiling.
This water heater is approved for installation in a closet or alcove with the clearances above.
