VENTING THE PELLET HEATER
Use an approved wall thimble when passing the vent through walls and a ceiling support/fi re stop spacer when passing the vent through ceilings (maintain a 3" clearance to any combustibles).
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 confi guration and air settings, black soot may occur on the terminal wall.
