Installation Instructions (cont'd)
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 tumlng "ON" gas to 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.
Venting
• 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.

AWARNING
VENT DAMPERS - Any vent damper, whether it is
operated 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 excess of 80% may
produce a relatively low flue gas temperature. Such
temperatures may not be high enough to properly open
thermally operated vent dampers. This would cause
spillage of flue gases and may cause carbon monoxide
poisoning.
Vent dampers must bear evidence of certification as
complying with the latest edition of the American
National Standard ANSI Z21.68 (ANSI Z21.66 & 67,
respectively, cover electrically and mechanically actuat-
ed vent dampers). Before installation of any vent
damper, consult the local Sears Service Center or gas
utility for further information.

A WARNING
To insure proper venting of this gas-fired water heater, the
correct vent pipe diameter must be utilized. Any additions or
deletions of other gas appliances 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.
Check tile venting system for signs of obstruction or deterioration
and replace if needed.
The combustion and ventilation air flow must not be obstructed.
AWARNING J
The water heater with draft hood installed must be properly J
vented to a chimney which terminates outdoors. Never oper*r,
ate the water heater unlessit isvented to the outdoors and has I
adequate air supplyto avoid risksof improper operation, explo-
s on or asphyx ation.
AWARNING
i Obstructed or deteriorated vent systems may present a serious
health risk or asphyxiation.
All vent gases must be completely vented to the outdoors of the
structure (dwelling). Install only the draft hood provided with
the new water heater and no other draft hood.
Vent pipes must be secured at each joint with sheet metal screws.
The water heater must be connected to a roof jack: The vent
pipe from the water heater to the roof jack must be no less than
the diameter of the draft hood outlet (min. 3") on the water
heater,
This water heater may be installed with single wall or Type B
vent pipe connection to the draft hood and the following U.L.
listed roof jacks not furnished.
Van Dyke Ind. No. 987
Vent Line No. 2073

There must be a minimum clearance of 12" between the top of
the draft hood and the top of the enclosure.
The draft hood and combustion air inlet to the water heater
must be in the same atmospheric pressure zone. Do not separate
by a wall, shelf, ceiling, partition, or any other means.
AWARNING
[
Failure to have required clearances between vent J
piping and combustible material will result in a fire [
hazard.

AWARNING
Be sure vent pipe is properly connected to prevent
escape of dangerous flue gases which could cause deadly
asphyxiat on.
