Removing the Old Water Heater
Attach a hose to the water heater
drain valve and put the other end
in a floor drain or outdoors. Open
the water heater drain valve. Open
a nearby hot water faucet which will
relieve pressure in the water
heater and speed draining. The
water passing out of the drain valve
may be extremely hot. To avoid
being scalded, make sure all
connections are tight and that the
water flow is directed away from
any person, see Figures 2 and 5.
0 Disconnect the vent pipe from the draft hood where it connects
to the water heater. In most installations the vent pipe can
be lifted off after any screw or other attached devices are
removed. Dispose of the draft hood. The new water heater
has a draft hood which must be used for proper operation.
If you have copper piping to the water heater, the two copper
water pipes can be cut with a hacksaw approximately four
inches away from where they connect to the water heater,
see Figure 6. This will avoid cutting off pipes too short.
Additional cuts can be made later if necessary. Disconnect
the temperature-pressure relief valve drain line. When the
water heater is drained, disconnect the hose from the drain
valve. Close the drain valve. The water heater is now
completely disconnected and ready to be removed.
serving all gas appliances is
used, also shut "OFF” the gas at
each appliance. Leave all gas
appliances shut "OFF” until the
water heater installation is
compieted, see Figures 2 and 3.
water heater at the water shut-off
valve or water meter. Some
installations require that the water
be turned off to the entire house,
see Figures 2 and 4.
Check again to make sure the gas supply is “OFF” to the
water heater. Then disconnect the gas supply connection
from the gas control valve.
If you have galvanized pipes to the water heater, loosen the
two galvanized pipes with a pipe wrench at the union in each
line. Also disconnect the piping remaining to the water heater,
see Figure 7. These pieces shouid be saved since they may
be needed when reconnecting the new water heater.
Disconnect the temperature-pressure relief valve drain line.
When the water heater is drained, disconnect the hose from
the drain valve. Close the drain valve. The water heater is
now compietely disconnected and ready to be removed.
Mineral buildup or sediment may have accumulated in the
old water heater. This causes the water heater to be much
heavier than normal and this residue, if spilled out, could
cause staining.
Facts to Consider About
the Location
Carefully choose an indoor location for the new water heater,
because the placement is a very important consideration for
the safety of the occupants in the building and for the most
economical use of the appliance. This water heater is not for
use in manufactured (mobile) homes or outdoor installation.
Whether replacing an old water heater or putting the water heater
in a new location, the following critical points must be observed;
* Select a location indoors as close as practical to the gas
vent or chimney to which the water heater vent is going to be
connected, and as centralized with the water piping system
as possible.
* Selected location must provide adequate clearances for
servicing and proper operation of the water heater.
CAUTION
Property Damage Hazard
heater’s pilot light or main burner. The resulting flashback and
fire can cause death or serious burns to anyone in the area.
Even though this water heater is a flammable vapors ignition
resistant water heater and is designed to reduce the chances
of flammable vapors being ignited, gasoline and other
flammable substances should never be stored or used in the
same vicinity or area containing a gas water heater or other
open flame or spark producing appliance.
Also, the water heater must be located and/or protected so it is
not subject to physical damage by a moving vehicle.
AWARNING
Fire Hazard
For continued protection against
risk of fire:
•Do not install water heater on
carpeted floor.
•Do not operate water heater if
flood damaged.
Ail water heaters eventually leak
Do notinstall without adequate drainage
Installation of the water heater must be accomplished in such a
manner that if the tank or any connections should leak, the flow
will not cause damage to the structure. For this reason, it is not
advisable to install the water heater in an attic or upper floor.
When such locations cannot be avoided, a suitable drain pan
should be installed under the water heater. Drain pans are
available at your local Sears or hardware store. Such a drain
pan must have a minimum length and width of at least 2 inches
(51 mm) greater that the water heater dimensions and must be
piped to an adequate drain. The pan must not restrict
combustion air flow.
A WARNING
Fire or Explosion Hazard
Do not store or use gasoline or other flammable
vapors and liquids in the vicinity of this or any other
appliance.
Avoid ail ignition sources if you smell LP gas.
Do not expose water heater control to excessive gas
pressure.
Use onlygasshownon rating plate.
Maintain required clearances to combustibles.
Keep ignition sources away from faucets after
V extended period of non-use.
Read instruction manual before
instailing, using or servicing
ê
water heater.
W I
This water heater must not be installed directly on carpeting.
Carpeting must be protected by metal or wood panel beneath
the appliance extending beyond the full width and depth of the
appliance by at least 3 inches (76.2mm) in any direction, or if
the appliance is installed in an alcove or closet, the entire floor
must be covered by the panel. Failure to heed this warning may
result in a fire hazard.
Awarning
Fire or Explosion Hazard
Read instruction manual before installing
using or servicing water heater.
Improper use may result in fire or
explosion
à
Minimum clearances between the water heater and combustible
construction are 0 inch at the sides and rear, 4 inches
{102 mm) at the front, and 6 inches (153 mm) from the vent
pipe, see Figure 8. Clearance from the top of the jacket is
12 inches (305 mm) on most models. Note that a lesser
dimension may be allowed on some models, refer to the label
attached adjacent to the gas control valve on the water heater.
Maintain required clearances to
combustibles.
