WARNING:
CODE COMPLIANCE
Use of aluminum Type B gas
vent for solid fuels is unsafe and
prohibited by the National Fire
Protection Association Code.
Use of aluminum Type B gas vent for solid fuels
is unsafe and prohibited by the National Fire
Protection Association Code. The
recommended method for connecting the boiler
to the chimney is to place a T-joint at the top of
the vertical section leading from the breach
(exhaust) flange. The rear opening must be
covered with a cap, which can be removed for
cleaning and inspection. A horizontal run must
be included, with provision for pipe
disassembly, for pipe inspection and removal of
any fly ash that accumulates. If the horizontal
run to the chimney is inclined, it will encourage
any fly ash, which drops in the pipe to fall back
into the ash separator.
If a second change of direction is required
before entering the chimney a cleanout “T”
should be placed at this point also as indicated
in Figure 1. Each joint should be secured with
three sheet metal screws and sealed with high
temperature sealant capable of withstanding
650
°
F. Any horizontal pipe should be pitched
upward toward the chimney at least ¼” for each
foot of horizontal run. Ensure that there is at
least 18” clearance between horizontal piping
and combustible ceiling. Ensure that the
chimney connection pipe extends at least 2” into
the chimney, but does not extend so far into the
chimney that it blocks airflow. A “T” must
always be used where the stovepipe changes
directions (rather than elbow) to allow for
cleanout.
Figure 1: Proper chimney connection
Particular attention should be paid to the point
where a flue passes through a wall or ceiling.
The pass-thru should always be made with
insulated pipe and the proper accessories or use
of a thimble that provides a diameter of not less
than three times the diameter of the stovepipe.
