Filling the Water Heater
A CAUTION I
Never use this water heater unlessIt is €ompletely Igled with I
weten To preventdamageto the tenk, the tankmust he filledI
with water. Water must flow from the hot water faucet
I before turn ng "ON" gasto the water heater. I
To fill the water heater with water:
• Close the water heater drain valve by turning the handle to
the right (clockwise). The drain valve is on the lower front of
the water heater.
Open the cold water supply valve to the water heater.
NOTE: The cold water supply valve must be left open
when the water heater is in use.
To insure compete filling of thetank, allow air to exit by
opening the nearest hot water f_ucet. Allow water to run
until a constant flow is obtained• This will let air out of the
water heater and the piping.
Check all new water piping for leaks. Repair as needed.
Venting
AWARNING
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed if its use inhibitsprop-
er drafting of the water heater,
Thermally Operated Vent Dampers: Gas-fired water heaters
havingthermal efficiency in excessof 80% may produce a rela-
tively low flue gas temperature. Such temperatures may not be
high enough to properly open thermally operated vent
damper_ This would causespillageof flue gasesand may cause
carbon monoxide poisoning.
Vent dampers must bear evidence of certification as complying
with the latest edition of American National Standard ANSI
Z21.68 (ANSI 721.66 & 67, respectively,cover electrically and
mechanically actuated vent dampers). Before installationof any
vent damper, consultyour localSears Service Center or the gas
utility for further information.
AWARNING
To insure proper venting of this gas-fired water heater, the
correct vent pipe diameter must be utilized. Any additions or
deletious of other gas applianceson a common vent with this
water heater may adversely affect the operation of the water
heater. Consult the local Sears Service Center or gas utility if
any such changesare planned.
For proper venting in certain installations, a larger diametervent
pipe may bi: necessary. Due to great variances in installations,
ira-foreseeableby the manufacturerof the water heater,you must
consult you[ gas company to aid you in determining the proper
ventingfor your water heater from the vent tables in the latestedi-
tion of the National Fuel Gas Code ANSI Z223.1, also referred to
as NFPA 54.
Check the venting system for signs of obstructionor deterioration
and replaceif needed.
The combustion and ventilation air flow must not be obstructed.
AWARNING
Obstructed or deteriorated vent systems m ay present a serious
healthrisk or asphyxiation.
• Place the draft hood legs in the receiving holes on the top of
the water heater. The legs will snap in the holes to give a tight
{it.
• Place the vent pipe over the draft hood. With the vent pipe in
position, drill a small hole through both the vent pipe and
draft hood. Secure them together with a sheet metal screw.

The water heater with_led must be properly
vented to a chimney which terminates outdoors. Never oper- [
ate the water heater unlessit is vented to the outdoors and has I
adequate air supplyto avoid risks of improper operation, exple-
don or asphyxiation. I
AWARNING I
The vent pipe from _ water heater must be no lessthan the
diameter of the draft hood outlet on the water heater, and I
must slope upward to the chimney at least ¼ inch per linear
