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.
