Breathing Hazard - Carbon Monoxide Gas
• Vent dampers must be certified
in accordance with ANSI Z21.6&
• Vent damper must permit proper
drafting of water heater.
• Install properly sized venting.
• Do not install without venting
outdoors.
• Do not install without drafthood.
• If common vented install in
accordance with NFPA 54.
• 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,
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.
For proper venting in certain installations, a larger diameter
vent pipe may be necessary. Consult your local Sears Service
Center or gas supplier to aid you in determining the proper
venting for your water heater from the vent tables in the current
edition of the National Fuel Gas Code ANSI Z223.1/NFPA 54.
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 vent pipe from the water heater must be no less than the
diameter of the draft hood outlet on the water heater and must
slope upward at least 1/4 inch per linear foot (21 mm per meter).

RGUREI&
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.
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, fellow
vent pipe manufacturer's clearance specifications. To insure
a tight fit of the vent pipe in a brick chimney, seal around the
vent pipe with mortar mix cement.
The water heater with draft hood installed must be connected
to a chimney or listed vent pipe system, 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.
For proper draft hood attachment, the draft hood legs may
be angled slightly inward.
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.
See Figure 17.
Breathing Hazard - Carbon Monoxide Gas
• Flue gases may escape if vent
pipe is not connected.
• Do not store corrosive chemicals
in vicinity of water heater
• Chemical corrosion of flue and
vent system can cause serious
injury or death.
• Contact a qualified installer or
service agency.
Breathing carbon monoxide can cause brain damage
or death Always read and understand instruction manual.
Obstructed or deteriorated vent systems may present serious Failure to have required clearances between vent piping and
health risk or asphyxiation, combustible material will result in a fire hazard.
