beforeturning "ON" gasto the water hea_.
For proper venting in certain installations, a largerdiameter vent
pipe may be necessary. Due to great variances in installations,
un-foreseeable 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
edition of the National Fuel Gas Code ANSI Z223.1, also
referred to as NFPA 54.
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 ro exit by
opening the nearest hot water faucet. 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. Repairas needed.

AWARNING
To insure proper venting of this gas-firedwater heater, the
correctventpipe diameter must be utilized.Any additions or
deletions of other gasappliances on a commonvent with this
water heater may adversely affectthe operationof the water
heater.Consultthe localSearsServiceCenter or gasutility if
anysuchchanges are planned.
Check the venting system for signs of obstruction or deteriora-
tion and replace if needed.
The combustion and ventilation air flow must not be obstructed.

Ob .structedor deteriorated ventsystems maypresenta serious
I 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
fit.
• Place the vent pi.pe 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.
