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" (305mm) from the wall, vertical terminations require a minimum 24"
(610mm) 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.
