Safety Precautions
A WARNING
The water heater with draft hood installed must be prop­
erly vented to a chimney which terminates outdoors.
Never operate the water heater unless it is vented to the
outdoors and has adequate air supply to avoid risks of
improper operation, explosion or asphyxiation.
A WARNING
Minimum clearances between the water heater and com­
bustible construction are I" at the sides and rear,
A" at the
front, and 6" from the vent pipe. Clearance from the top of the
jacket is 18". Refer to the label on the water heater adjacent to
the gas control valve for all clearances.
A CAUTION
WATER HEATERS EVENTUALLY LEAK: Installation of
the water heater must be accomplished in such a manner
that if the tank or any connections should leak, the flow of
water 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 avoid­
ed, a suitable drain pan should be installed under the
water heater. Drain pans are available at your local Sears
store. Such a drain pan must be not greater than I
¡/2
inches deep, have a minimum length and width of at least
2 inches greater than the water heater dimensions and
must be piped to an adequate drain. The pan must not
restrict combustion air flow. Under no circumstances is
the manufacturer or Sears to be held liable for any water
damage in connection with this water heater.
AWARNING
Do not use this appliance if any part of it has been under
water. Immediately call a Sears Service Technician to
inspect the appliance and to replace the gas control or any
part of the burner systeifl which has been under water.
AWARNING
HYDROGEN GAS: Hydrogen gas can be produced in a hot
water system that has not been used for a long period of
time (generally two weeks or more). Hydrogen gas is
extremely flammable and explosive. To prevent the possi­
bility of injury under these conditions, we recommend the
hot water faucet be opened for several minutes at the
kitchen sink before any electrical appliances which are
connected to the hot water system are used (such as a
dishwasher or washing machine). If hydrogen gas is pre­
sent, there will probably be an unusual sound similar to air
escaping through the pipe as the hot water faucet is
opened. There must be no smoking or open flame near
the faucet at the time it is open.
AWARNING
INSULATING JACKETS; When installing an external
water heater insulation jacket on a gas water heater:
• DO NOT cover the temperature-pressure relief valve.
• DO NOT put insulation over any part of the top of the
gas water heater.
• DO NOT put insulation over the gas control valve or gas
control valvefburner cover, or any access areas to the
burner.
• DO NOT let insulation around the gas water heater to
get within 8 inches of the floor (air must get to the
burner).
• DO NOT cover or remove operating instructions, and
safety related warning labels and materials affixed to the
water heater.
Failure to heed this will result in the possibility of a fire or
explosion.
