Filling the Water Heater
A CAUTION
Never use this water heater unless it is completely filled with
water. To prevent damage to the tank, the tank must be filled
with water. Water must flow from the hot water faucet
before turn ng ON gasto the water heater.
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 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.
AWARNING
To insure proper venting of this gas-fired water heater, the I
correct vent pipe diameter must be utilized. Any additions or
deletions of other gasappliances on 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 changes are planned.
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 tl_e 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.

The draft hood supplied with this water heater must be installed as "
shown beforethe heater isoperated.
If the draft hood is removed for cleaning or replacement it must be
replaced in reverseorder as removed.
AWARNING
VENT DAMPERS - Any vent damper, whether it is operated
thermally or otherwise must be removed if its useinhibits prop-
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 gastemperature. Such temperatures may not be
high enough to properly open thermally operated vent
dampers. 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 Z21.66 & 67, respect_ely, cover electrically and
mechanically actuated vent dampers). Before installation of any
vent damper, consult your local SearsService Center or the gas
utility for further information.

adequate air supplyto avoid Hsksof improper operation, explo- [
slon or asphyxiation. !
AWARNING ]
The vent pipe from thrust be no lessthan the I
diameter of the draft hood outlet on the water heater, and I
must slope upward to the chimney at least ¼ inch per linear I
foot ]
All vent gases must be completely vented to the outdoors of the
structure (dwelling). Installonly the draft hood provided with
