Per national building codes, consideration must
be given to combustion air supply to all combustion
appliances. Failure to supply adequate combustion air
for all appliance demands, may lead to back-drafting of
those and other appliances.
When the appliance is side-wall vented: The air
intake is best located on the same exterior wall as the
exhaust vent outlet and located lower on the wall than
the exhaust vent outlet.
When the appliance is roof vented: The air intake is
best located on the exterior wall oriented towards the
prevailing wind direction during the heating season.
The outside air connection will supply the demands of
the pellet appliance, but consideration must be given to
the total house demand. House demand may consume
some air needed for the stove, especially during a power
failure. It may be necessary to add additional ventilation
to the space in which the pellet appliance is located.
Consult with your local HVAC professional to determine
the ventilation demands for your house.
To install outside air use 2 3/8" I.D. non-combustible
flex pipe. There is a break-away hole on the rear
panel of the P68 stove which must be removed before
connecting the flex pipe. The pipe should be run outside
and terminate to the side or below the vent pipe outlet
so the flue outlet is more than 12" from the inlet cover.
The maximum length run of this pipe is 15 feet. If a
longer run is needed the size must be increased to 3".
Inlet cover, part number 1-10-08542 should be used to
keep birds, rodents, etc.out of the pipe.
You may choose to use the optional Direct Vent Wall
Passthrough Kit (part #1-00-677077) which incorporates
the venting passthrough and outside air inlet into one
component.
notice:
In Canada, ULC-S627 requires that all
outdoor-aired space heaters be secured to the structure.
vent configurations:
To reduce probability of reverse drafting during shut-down conditions, Hearth & Home Technologies strongly
recommends:
• Installing the pellet vent with a minimum vertical run of five feet, preferably terminating above the roof line.
• Installing the outside air intake at least four feet below the vent termination.
To prevent soot damage to exterior walls of the house and to prevent re-entry of soot or ash into the house:
• Maintain specified clearances to windows, doors, and air inlets, including air conditioners.
• Vents should not be placed below ventilated soffits. Run the vent above the roof.
• Avoid venting into alcove locations.
• Vents should not terminate under overhangs, decks or onto covered porches.
• Maintain minimum clearance of 12 inches from the vent termination to the exterior wall. If you see deposits
developing on the wall, you may need to extend this distance to accommodate your installation conditions.
hearth & home technologies assumes no responsibility for, nor does the warranty extend to, smoke
damage caused by reverse drafting of pellet appliances under shut-down or power failure conditions.
