LOCATING THE HEATER

WARNING

THERE IS A RISK IN USING FUEL BURNING APPLIANCES

SUCH AS GAS WATER HEATERS IN ROOMS, GARAGES OR

OTHER AREAS WHERE GASOLINE, OTHER FLAMMABLE

LIQUIDS OR ENGINE DRIVEN EQUIPMENT OR VEHICLES ARE

STORED, OPERATED OR REPAIRED. FLAMMABLE VAPORS

ARE HEAVY AND TRAVEL ALONG THE FLOOR AND MAY BE

IGNITED BY THE HEATER’S PILOT OR MAIN BURNER FLAMES

CAUSING FIRE OR EXPLOSION. SOME LOCAL CODES

PERMIT OPERATION OF GAS APPLIANCES IN SUCH AREAS

IF THEY ARE INSTALLED 18” (.50m) OR MORE ABOVE THE

FLOOR. THIS MAY REDUCE THE RISK IF LOCATION IN SUCH

AN AREA CANNOT BE AVOIDED.

DO NOT INSTALL THIS WATER HEATER DIRECTLY ON A

CARPETED FLOOR. A FIRE HAZARD MAY RESULT. Instead

the water heater must be placed on a metal or wood panel

extending beyond the full width and depth by at least 3 inches

(7.6cm) in any direction. If the heater is installed in a carpeted

alcove, the entire floor shall be covered by the panel. Also, see

the DRAIN REQUIREMENTS.

THE HEATER SHALL BE LOCATED OR PROTECTED SO IT IS

NOT SUBJECT TO PHYSICAL DAMAGE BY A MOVING

VEHICLE.

WARNING

FLAMMABLE ITEMS, PRESSURIZED CONTAINERS OR ANY

OTHER POTENTIAL FIRE HAZARDOUS ARTICLES MUST

NEVER BE PLACED ON OR ADJACENT TO THE HEATER.

OPEN CONTAINERS OR FLAMMABLE MATERIAL SHOULD

NOT BE STORED OR USED IN THE SAME ROOM WITH THE

HEATER.

When installing the heater, consideration must be given to proper

location. Location selected should be as close to the stack or

chimney as practicable, with adequate air supply and as

centralized with the piping system as possible.

THE HEATER MUST NOT BE LOCATED IN AN AREA WHERE

IT WILL BE SUBJECT TO FREEZING.

LOCATE IT NEAR A FLOOR DRAIN. THE HEATER SHOULD

BE LOCATED IN AN AREA WHERE LEAKAGE FROM THE

HEATER OR CONNECTIONS WILL NOT RESULT IN DAMAGE

TO THE ADJACENT AREA OR TO LOWER FLOORS OF THE

STRUCTURE.

WHEN SUCH LOCATIONS CANNOT BE AVOIDED, A SUITABLE

DRAIN PAN SHOULD BE INSTALLED UNDER THE HEATER.

Such pans should be fabricated with sides at least 2" (5cm) deep,

with length and width at least 2" (5cm) greater than the diameter

of the heater and must be piped to an adequate drain. The pan

must not restrict combustion air flow.

For appliance installation locations with elevations above 2000

feet (610m), refer to HIGH ALTITUDE INSTALLATIONS section

of this manual for input reduction procedure.

LEVELING

If the unit is not level, insert the bolts which were used in crating

into the legs to correct this condition.

CLEARANCES

These heaters are approved for installation on combustible flooring

in an alcove when the minimum clearance from any combustion

construction are followed as indicated in figure 6 and Table 1.
