VENTING
The following installation guidelines must be followed to ensure conformity with both the safety listing of this stove and to local building codes.
Note: Where passage through a wall, or partition of combustible construction is desired, the installation shall conform to CAN/CSA
TYPE OF VENT
Pellet venting pipe (also known as L vent) is constructed of two layers with air space between the layers. This air space acts as an insulator and reduces outside surface temperature of pipe to allow a clearance to combustibles of only 3”.
A UL listed 3” or 4” type L pellet vent exhaust system must be used for installation and attached to the pipe connector provided on the back of the stove. Use a 3” to 4” adapter for 4” pipe. A cap must be used at the termination of type L vent chimneys. For elevations above 2,500 feet above sea level, a 4” L is required.
PELLET VENT INSTALLATION
Termination must exhaust above air inlet elevation. Installation MUST include three vertical feet of pellet vent pipe.
This will create some natural draft to prevent the possibility of smoke or odor during appliance shutdown and to keep exhaust from causing a nuisance or hazard from exposing people or shrubs to high temperatures.
The installation must include a clean out tee to enable collection of fly ash and to permit periodic cleaning of the exhaust system. 90º elbows accumulate fly ash and soot thereby reducing exhaust flow and performance of the stove. Each elbow or tee reduces draft potential by 30% to 50%. Use no more than 180º of elbows (two 90º elbows, or two 45º and one 90º elbow, etc.) to maintain adequate draft.
Total length of horizontal vent must not exceed 10 feet.The maximum recommended vertical venting height is 12 feet for 3” type L vent. All joints for connector pipe are required to be fastened with at least three screws and all pellet vent connections must be sealed according to manufacturer’s recommendations.
The area where the vent pipe goes through to the exterior of the home must be sealed with silicone or other means to maintain the vapor barrier between the exterior and the interior of the home.
WARNING
DO NOT CONNECT THIS UNIT TO A CHIMNEY FLUE SERVING ANOTHER APPLIANCE.
DO NOT INSTALL A FLUE DAMPER IN THE EXHAUST VENTING SYSTEM OF THIS UNIT.
do not connect directly to a masonry chimney.
Do notterminatevent in any enclosed or semi- enclosed area, such as; carports, garage, attic, crawl space, under a sun deck or porch, narrow walkway or closed area, or any location that can build up a concentration of fumes such as a stairwell, covered breezeway etc.
CAUTION
Vent surfaces can get hot enough to cause burns iftouched by children. Noncombustible shielding or guards may be required.
PELLET VENT MUST MAINTAIN A MINIMUM 3 INCH CLEARANCE TO ANY COMBUSTIBLE.
INSTALL VENT AT CLEARANCES SPECIFIED BY THE VENT MANUFACTURER.
All venting, whether vertical or horizontal, joints should be made GAS tight with recommended sealants.
