hood and fasten with four (4) corrosion-resistant
sheet metal screws.
The vent damper supplied with the boiler must be used
for venting the boiler only.
USER NOTE
In Canada the vent damper must not be
installed on a propane-fired heating
system with an electronic ignition system.
The position of the vent damper must be visible.
The back flow check must be at least six inches from all
flammable components.
The vent damper must be freely accessible for
maintenance.
The vent damper must be open when the main burner of
the boiler is operating.

check with three (3) corrosion-resistant sheet metal
screws.
Connecting flue pipe
4. Connect flue pipe to the chimney with the shortest
possible length of flue pipe.
Use only flue pipes with a suitable diameter for the
boiler.
Every horizontal section of the flue pipe must have a
minimum rise of 1/4 inch per foot towards the chimney.
The flue pipe must be securely fastened to prevent it
from hanging. A support must be installed at least every
five feet. Fasten every connection with at least three (3)
corrosion-resistance sheet metal screws. The end
