Venting
WARNING
VENT DAMPERS - Any vent damper, whether it isol_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 gasesand
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.
