Figure 12 -Typical Chimney Connection
Chimney Connector And Draft Regulator
• Venting the boiler requires 6” diameter chimney
connector pipe and use of manufacturer provided draft
regulator.
•
Regulator, when properly installed, automatically
controls the draft.
•
Install in horizontal section of pipe, may also be
installed in angled or vertical section of pipe.
• Verify “top” of regulator is at the top and short pipe
section which holds the vane is horizontal.
• Even though locating draft regulator close to chimney
reduces noise,
install draft regulator as close as
practicable to the boiler.
•
Install chimney connector, start at boiler with vertical
pipe, elbow, then install draft regulator horizontally.
•
When regulator is in place, start at chimney and work
back to the regulator.
•
Join the two sections with draw-band.
•
Horizontal pipe must slope up toward the chimney at
least 1/4 inch per linear foot of venting.
•
Chimney connector must not leak and must be firmly
supported.
•
Join each section with at least two sheet metal screws.
Support every second section with a stovepipe wire.
