Venting - Kenmore THE ECONOMIZER 153.333850 Owner's Manual

To fillthe water heater with water:
I. Close the water heater drain v alve b yturning the handle tothe right
(clockwise). The drain v alve i sonthe lower front ofthe water heater.
2. Openthecoldwatersupply valveto thewaterheater.
NOTE: The cold water supply valve must be left open when
the water heater is in use,
3. 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.
4. Check all water piping and connections 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.

temperature. Such temperatures may not be high enough to properly
open thermally operated vent dampers. This would cause spillage of
the flue gases and may cause carbon monoxide poisoning.
Vent dampers must bear evidence of certification as complying with
the current 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 gas utility for further information.
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 your gas
supplier if any such changes are planned.
Periodically 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 water heater with draft hood installed must be connected to a
roof jack, which terminates to the outdoors. Never operate the water
heater unless it is vented to the outdoors and has adequate air supply
to avoid risks of improper operation, explosion or asphyxiation.
Obstructed or deteriorated vent systems may present serious health
risk or asphyxiation.
The vent pipe from the water heater must be no less than the
diameter of the draft hood outlet on the water heater.
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.
There must be a minimum of 6 inches (153 mm) clearance between
single wall vent pipe and any combustible material. For other than single
wall, follow vent pipe manufacturer's clearance specifications.
Failure to have required clearances between vent piping and
combustible material will result in a fire hazard.
Breathing Hazard - Carbon Monoxide Gas
• Vent dampers must be certified
in accordance with ANSI Z21.68.
• Vent damper must permit proper
drafting of water heater.
• Install properlysizedventing.
• Do not install without venting
outdoors.
• Do notinstallwithoutdrafthood.
• Be alert for obstructed or deterio-
rated vent system to avoid
serious injury or death.
Breathing carbon monoxide can cause brain damage or
death. Always read and understand instruction manual.
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.
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" [76 mm]) 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
White Metal Products 3RJ
There must be a minimum clearance of 12" (305 mm) 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.
There must be a minimum of 6 inch clearance between single wall
vent pipe and any combustible material. Fill and seal any clearance
between single wall vent pipe and combustible material with mortar
mix, cement or other noncombustible substance. For other than single
wall, follow vent pipe manufacturer's clearance specifications.
Thermally Operated Vent Dampers: Gas-fired water heaters having Be sure vent pipe is properly connected to prevent escape of
thermal efficiency in excess of 80% may produce a relatively low flue gas dangerous flue gases which could cause deadly asphyxiation.
