3.4 Connections to the Boiler
The following connections must be made to the boiler, in order for it to function:
The boiler flue gas exhaust collar must be connected to the chimney system.
The heating system piping must be connected to the boiler supply and return connections.
Electrical power must be provided at the boiler electrical terminal box.
3.4.1 Chimney Connection
The connection between the boiler and the chimney system should be single wall 24 gauge (minimum)
stainless or black pipe, unless prohibited by the local code authority.
The single wall chimney connector must not pass through an attic, roof space, closet or similar
concealed space, or a floor, or ceiling.
Where passage through a wall or partition of combustible construction is desired, the installa-
tion must conform to NFPA 211.
The chimney connection pipe must be placed over the outside of the boiler’s flue gas exhaust
pipe
(Fig. 3.4).
A boiler flue with an internal dimension of 5.8” (149mm) is used – see specifi-
cation data in
Section 6.3.
The chimney connector sections must be attached to the boiler and to each other with the
crimped (male) end pointing away from the boiler. All joints, including the connection at the
boiler collar, must be secured with three sheet metal screws. All joints need to be sealed with a
Hi-Temp silicone.
A barometric regulator (draft damper), if used, should be incorporated into the connector
(Refer to page 13 for more information).
