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.

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,  it  is  recommended 

that a suitable drain pan, adequately drained, be installed under 

 

the appliance.

Water  heater  life  depends  upon  water  quality,  water  pressure 

and the environment in which the water heater is installed. Water 

heaters are sometimes installed in locations where leakage may 

result in property damage, even with the use of a drain pan piped 

to a drain. However, unanticipated damage can be reduced or 

prevented  by  a  leak  detector  or  water  shut-off  device  used  in 

conjunction with a piped drain pan. These devices are available 

from some plumbing supply wholesalers and retailers, and detect 

and react to leakage in various ways:

•  Sensors  mounted  in  the  drain  pan  that  trigger  an  alarm  or 

turn off the incoming water to the water heater when leakage 

 

is detected.

•  Sensors  mounted  in  the  drain  pan  that  turn  off  the  water 

 

supply  to  the  entire  home  when  water  is  detected  in  the 

 

drain pan.

•  Water supply shut-off devices that activate based on the water 

pressure  differential  between  the  cold  water  and  hot  water 

pipes connected to the water heater.

•  Devices that will turn off the gas supply to a gas water heater 

while at the same time shutting off its water supply.

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” (5 cm) deep, with length and width at least 2” (5 cm) 

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 (610 m), 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 2.

The National Sanitation Foundation also recommends circulation 

of  180°F  (82°C)  water.    Where  this  is  done,  the  circulation 

should be very gentle so that it does not cause any unnecessary 

turbulence inside the water heater.  The circulation should be just 

enough to provide 180°F (82°C) water at the point of take-off to 

the dishwashing machine.  Adjust flow by means of the plug cock 

in the circulating line.

INSTALLATION INSTRUCTIONS

REQUIRED ABILITY

INSTALLATION  OR  SERVICE  OF  THIS  WATER  HEATER 

REQUIRES ABILITY EQUIVALENT TO THAT OF A LICENSED 

TRADESMAN IN THE FIELD INVOLVED.  PLUMBING, AIR 

SUPPLY, VENTING, GAS SUPPLY AND ELECTRICAL WORK 

ARE REQUIRED.

 WARNING

FAILURE TO FOLLOW THESE INSTRUCTIONS CAN RESULT 

IN SERIOUS PERSONAL INJURY OR DEATH.

UNCRATING

The heater is shipped with the flue damper already installed.  The 

wiring conduit runs from the thermostat to the damper drive cover.  

Before turning unit on, check to make sure the wiring conduit is 

securely plugged into damper drive. 

LOCATING  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.

 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” (.50 m). 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 (7.6 cm) 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
