Filling the Water Heater
CAUTION
Never use this water heater unlessit is completely filled
with water. To prevent damageto the tank, the tank must
be filled with water_Water mustflow from the hot water
faucet before turning "ON" gas to the water heater.
To fill the water heater with water:
1, Close the water heater drain valve by turning the han-
dle to the right (clockwise) The drain valve is on the
lower front of the water heater.,
2 Open the cold water supply valve to the water heater
NOTE: The cold water supplyvalve must be left open
when the water heater ism use.
3, To insurecomplete filling of the tank, allow air to exit
by opening the nearest hot water faucet.. Allow water
to run untila constant flow is obtained., This will let air
out of the water heater and the piping.
4. Check all new water piping for leaks° Repair as needed,
Venting
WARNING
VENT DAMPERS - Any vent damper, whether it is ol_erated
thermally or otherwise must be removed if its use Inhibits
proper drafting of the water heater.
Thermally Operated Vent Dampers: Gas-fired water heaters
having thermal efficiency in excessof 80% may produce a
relatively low flue Rastemperature. Such temperatures may.
not be high enough to properly open thermally operated
vent dampers. Thm_swould cause spillage of flue gases and
may causecarbon monoxide poisoning.
Vent dampers must bear evidence of-certification as com-
plying widththe latest edition of the American National
Standard ANSI Z21.68 (ANSI Z21_66 & 67, respectively,
cover electrically and mechanically actuated vent dampers).
Before installation of any vent damper, consult the local
Sears Service Center or gas utility for further information.

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.

Gas Code ANSI Z223 1, also referred to as NFPA54
Check the venting system for signs of obstruction or deterio-
ration and replace if needed,
The combustion and ventilation air flow must not be
obstructed
WARNING
Obstructed or deteriorated vent systemsmay present
serioushealth riskor asphyxiation_

top of the water heater,,The legs will snap in the holes
to give a tight fit.
2, 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,
