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 propedy sized venting

•Do not install without venting outdoors.

•Do not install wit bout draffhood.

•If common vented install in accordancewith 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.

DRAFT HOOD _..__OR CHIMNEY

RGURE 17,

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), see Figure 18.

CHIMNEY

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 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. Secure two legs to top with sheet metal screws.

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.

Obstructed or deteriorated vent systems may present serious health risk or asphyxiation,

RGURE 18,

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, follow 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.

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 injuryor death.

•Contact a qualified installer or service agency.

Breathing carbon monoxide can cause brain damage or death. Always read and understand instruction manual.

Failure to have required clearances between vent piping and combustible material will result in a fire hazard.
