WARNING

Do not use this boiler with galvanized, Type 304 or Type 316 stainless steel, non metallic or any other non AL29-4C®based vent systems.

Do not use a barometric damper or drafthood with this appliance.

Do not use vent dampers with this boiler.

Moisture and ice may form on surfaces around termination. To prevent deterioration, surfaces should be in good repair (sealed, painted, etc.).

This appliance needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air.

Do not reduce size of air intake pipe.

Read, understand and follow combustion air instruction restrictions contained in the Pre-Installation instructions of this manual.

Do not operate appliance where gasoline or other flammable vapors or liquids, or sources of hydro- carbons (i.e. bleaches, cleaners, chemicals, sprays, paint removers, fabric softeners, etc.) are used, stored and/or present in the air.

When installing vent pipe through chimney, no other appliance can be vented into the chimney.

Do not exceed maximum vent/air intake lengths. Refer to Table 4.
