Filling the Water Heater
A CAUTION
Never usethisvrat_r heater unless it iscompletelyElled with I
water. To preve_ damnge to the tenk, the tenk must be filled I
with water. Water must flow from the hot water faucet
before turn ng ' ON ' gas to the water beater.
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 complete filling of the tank, allow air to exit by
opening the nearest hot water faucet. Allow water to tun
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
Ai.WARNING
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed if its use inhibit3 prop-
er drafting of the water heate_.
Thermally Operated Vent Dampers: Gas-fired water heaters
having thermal efficiency in eacess of 80% may produce a rela-
tively
low flue gastemperature. Such temperatures may not be
high enough to properly open thermally operated vent
dampers. This wonld ceuse spillageof flue gasasand rnay canse
ced_on monoKide poisoning.
Vent dampen must bear evidenceof certification as complying
with the latest edition of American National Standard ANSI
Z21.68 (ANSI Z21.66 & 67, respecd_, cover electrically and
mechanically actuated vent dampers). Before installationof any
vent dampe_ comuit your local Sears Service Center or the gas
utility for further information.
&WARNING
To insure proper venting of this gas-fired water heater,the
correctvent pipediameter mustbe utilized.Any additions or
deletionsof other gasappliances on a commonvent with this
water heater may adversely _q_ct the operationof the vm_r
heater,Consultthe localSearsService Center or gasutility if
any suchchanges areplanned.
For proper venting in certain installations, a larger diameter vent
pipe may be necessary. Due to great variances in installations,
unforeseeable by the manufacturer of the water heater, you must
consult your gas company to aid you in determining the proper
venting for your water heater from the vent tables in the latest edi-
tion of the National Fuel Gas Code ANSI Z223.1, also referred to
as NFPA 54.
Check the venting system for signs of obstruction or deterioration
and replace if needed.
The combustion and ventilation air flow must not be obstructed.
AWARNING
Obstructed or deter_ratedventsystems _ present a serious
healthriskor 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
fit.
• 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.
