4.0 VENTING
4.1
TYPE OF VENT
EN
Must be an approved 3" (76.2mm) or 4" (102mm) 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 appliance installations. Use 4" (102mm) diameter vent if vent or liner height is over 15' (4.6m) or if
installation is over 4,000' (1219m) above sea level.
4.2
PELLET VENT INSTALLATION
PELLET VENT MUST MAINTAIN A MINIMUM 3" (76.2mm) CLEARANCE TO ANY COMBUSTIBLE (INSTALL
VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER, CHIMNEY LINER EXCLUDED).
DO NOT CONNECT THE PELLET VENT TO A VENT OR CHIMNEY SERVING ANY OTHER APPLIANCE OR
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.
The vent must have a support bracket every 5' (1.5m)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' (10.1m)
Maximum horizontal without vertical rise is 5' (1.5m) straight
off the back of the appliance. 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' (0.9m) 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" (6.4mm) rise every 12" (304.8mm) of travel if
longer than 3' (0.9m).
The pellet vent connections must be sealed with HI-Temp
RTV Silicone and screwed together with at least 3 3/8"
(85.7mm) 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.
4.3
VENTING THE PELLET APPLIANCE
Use an approved wall thimble when passing the vent through walls and a ceiling support / fi restop spacer
when passing the vent through ceilings (maintain a 3" (76mm) clearance to any combustibles).
