5.10.3 Installing the flue pipe
▶ Attach vent pipe to flue outlet of draft hood.
▶ Fasten the vent pipe with 4 corrosion-resistant sheet metal screws.
5.10.4 Connecting the flue connector
Use only flue pipes with a suitable diameter for the boiler.
Every horizontal section of the flue pipe must have a minimum rise of
¼ inches per foot (21 mm per m) towards the chimney. The flue pipe
must be securely fastened to prevent it from sagging. A suspension must
be installed at least every 5 feet (1.5 m). Fasten every connection with
at least 3 corrosion-resistance sheet metal screws. The terminal end of
the flue gas routing must connect to the inside of the chimney smoke
duct.
A minimum clearance of 6 inches (155 mm) is required between the
vent pipes and all flammable materials.
The flue pipe must not be reduced in size and venting must not be
prevented by the installation of additional components.
▶ Connect vent pipe to the chimney with the shortest possible length of
vent pipe.
5.10.5 Installing a vent damper (optionally available)
The vent damper supplied with the boiler must be used solely for venting
the boiler.
The position of the vent damper position blade must be visible.
The flue gas collector must be at least 6 inches (155 mm) from all
flammable components.
The vent damper must be readily accessible for preventive
maintenance.
The vent damper must be open when the main burner of the boiler is
operating.
▶ Place flue gas adapter [3] on the pipe nipples of the draft diverter.
▶ Install pins in the holes provided in the vent damper [1].
▶ Fasten vent damper to the flue gas adapter with three (3) corrosion-
resistant sheet metal screws.

DANGER: Risk of fatal injury from escaping flue gases!
A flue gas collector that does not work properly can allow
dangerous flue gases to escape.
▶ Do not change the flue gas collector.
In Canada the vent damper must not be installed on a
propane-fired heating system with an electronic ignition
system.
