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.
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.
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.
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.
FLAMMABLE ITEMS, PRESSURIZED CONTAINERS OR ANY
OTHER POTENTIAL FIRE HAZARDOUS ARTICLES MUST
WARNING
WARNING
Instead the
WARNING
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.
W H E N S U C H LO C AT I O N S C A N N OT B E AVO I D E D,
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.
