The temperature-pressure relief valve must be manually
operated at least once a year. Caution should be taken
to ensure that (1) no one is in front of or around the outlet
of the temperature-pressure relief valve discharge line,
and (2) the water manually discharged will not cause any
bodily injury or property damage because the water may be
extremely hot.
If after manually operating the valve, it fails to completely
reset and continues to release water, immediately close
the cold water inlet to the water heater, follow the draining
instructions, and replace the temperature-pressure relief valve
with a new one.

Venting
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed if its use inhibits proper
drafting of the water heater.
Thermally Operated Vent Dampers: This gas-fired water
heaterhasathermalefciencyatorabove80%whichmay

may not be high enough to properly open thermally operated
ventdampers.Thiswouldcausespillageoftheuegasesand
may cause carbon monoxide poisoning.

with the current edition of the American National Standard
ANSI Z21.66/CGA 6.14, cover electrically and mechanically
actuated vent dampers). Before installation of any vent damper,
consult your local Sears Service Center or the local gas supplier
for further information.
Toinsureproperventingofthisgas-redwaterheater,thecorrect
vent pipe diameter must be utilized. Any additions or deletions
of other gas appliances on a common vent with this water heater
may adversely affect the operation of the water heater. Consult
your gas supplier if any such changes are planned.
For proper venting in certain installations, a larger diameter vent
pipe may be necessary. Consult your local Sears Service Center
or gas supplier to aid you in determining the proper venting for
your water heater from the vent tables in the current edition of
the National Fuel Gas Code ANSI Z223.1/NFPA 54.
Periodically check the venting system for signs of obstruction or
deterioration and replace if needed.
Thecombustionandventilationairowmustnotbeobstructed.
The water heater with draft hood installed must be connected
to a chimney or listed vent pipe system, which terminates to the
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.
