exceeding 56.55 in
•
Use three sheet metal screws at each single wall chimney connector joint (check manufacturer's
recommendations when double wall chimney connector is used).
•
Drill three holes in the flue collar of the unit and attach the chimney connector to the unit using sheet metal
screws (holes should be pre‐drilled in flue collar from factory).
•
Avoid numerous elbows and excessive horizontal runs as both will lead to poor draft and increased creosote
accumulation. Horizontal runs of chimney connector must never exceed 4.0 ft. and the overall length of the
chimney connector must not exceed 8.0 ft. with single wall black connector pipe. If necessary to run longer than
8.0 ft. of chimney connector pipe, double wall black chimney connector pipe must be used.
•
A tight seal at the thimble is crucial for proper unit performance and to create a safe installation. Use the proper
adapter designed for connecting single or double wall chimney connector to a masonry thimble.
•
Have existing masonry chimneys inspected for safety and proper clearances to combustibles before putting them into
service; a qualified chimney sweep can perform this inspection.
•
External masonry chimneys often suffer cold downdrafts and poor draft performance even when they meet the
cross‐sectional area rules. In this case, a 6.0" insulated liner may be necessary.
