4.1 TYPE OF vENT
4.2 INSTALLING ThE PELLET vENT
4.3 vENTING ThE PELLET hEATER
Must be an approved 3" or 4" diameter Type "L" or "PL" vent, vented to the outside or connect the vent to a
factory built type "A" chimney using an adaptor; and/or stainless steel chimney liner for masonry fireplace
installations. Use 4" diameter vent if vent or liner height is over 15' or if installation is over 4,000' above sea
level.
The vent must have a support bracket every 5' when on the exterior wall.
To achieve optimum performance, keep vent runs as short as possible,
especially on horizontal installations.
MAXIMUM VENTING: Maximum venting height is 33'. Maximum
horizontal vent run is 10'. Use no more than 180° of elbows (two
90' elbows, or two 45' elbows and one 90' elbow, etc), excluding
the tee and the termination.
VENT INSTALLATION: Termination must exhaust above the air
inlet elevation, and parallel or above the exhaust output of the
pellet appliance. It is recommended that at least 3' of vertical pipe
be installed to create some natural draft. This is to help prevent the
possibility of smoke or odour entering the home during the appliance
shut down or in the event of a power outage. Horizontal sections must
have a 1/4" rise every 12" of travel if longer than 3'.
The pellet vent connections must be sealed with HI-Temp RTV
Silicone and screwed together with at least 3-3/8" long stainless
steel screws. Seal each vent section by injecting a liberal
amount of 500°F (260°C) RTV silicone sealant into the gap.
We recommend sealing the outside of the vent connections to
permit easier access when servicing.

4.4 PELLET vENT TERmINATION
The vent termination must have an approved cap (to prevent water from entering) or a 45° downturn.
If the termination is located on a windy side of the house, a shield is recommended to prevent soot from
building up on the side of the house.
Horizontal terminations must protrude 12" from the wall, vertical terminations require a minimum 24" above the
highest point that it penetrates through the roof.
Depending on pellet quality, vent configuration and air settings, black soot may occur on the terminal wall.
!
WARNING
Pellet vent must maintain a minimum 3" clearance to any combustible (install vent at clearances
specified by the vent manufacturer).
Do not connect the pellet vent to a vent or chimney serving any other appliance or heater.
Do not install a flue damper in the exhaust venting system of this unit.
