INTRODUCTION
This instruction manual covers the use of a Chimney adapter kit for installations having tile-lined
masonry chimneys. The chimney adapter will reduce the amount of condensation in the flue system and
prevent excessive and premature deterioration of the tile and brick mortar joints. This kit may only be
installed if the following requirements are met:
1. The 99% winter design temperature shall not be lower than 100F for exterior chimneys. (Refer to
Figure G-19 in the National Fuel Gas Code).
2. Chimney construction shall conform to the Standard for Chimneys, Fireplaces, Vents, and Solid
Fuel Burning Appliances (ANSI/NFPA 211).
3. The furnace must bear a factory applied label stating the Chimney Adapter kit number that may
be used.
4. An operational draft hood equipped water heater may be common vented with the furnace.
Additional draft hood equipped appliances may also be added to the venting configuration.
5. Type B double-wall metal vent must be used for all furnace and water heater vent connectors.
6. Furnace oversizing must not exceed 70% of the winter design heating load.
Refer to the National Fuel Gas Code (NFPA54) or B149.1 &.2 (Canada) for information on chimney
sizing information. The following “Table 1” has been extracted from NFPA54:
