Pellet Vent Termination; Vent Terminal Clearances - Napoleon NPS45 Installation And Operating Instructions Manual

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 build-
ing 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.
