tion must conform to NFPA 211 or to Canadian CAN/CSA B365
The chimney connection pipe must be placed over the outside of the boiler’s flue gas exhaust
pipe

The chimney connector sections must be attached to the boiler and to each other with the
crimped (male) end pointing towards the boiler. All joints, including the connection at the
boiler collar, must be secured with three sheet metal screws.
A barometric regulator (draft damper), if used, should be incorporated into the connector
