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 excess of 80% may produce a
relatively low flue Rastemperature. Such temperatures may.
not be high enough to properly open thermally operated
vent dampers. Thm_s would cause spillage of flue gases and
may cause carbon monoxide poisoning.
Vent dampers must bear evidence of-certification as com-
plying width the 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.
from the vent tables in the latest edition of the National Fuel
Gas Code ANSI Z223 1, also referred to as NFPA 54
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 systems may present
serious health risk or 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
