Vent pipe minimum clearance to combustible
material is 1in. (25mm). combustion air pipe
minimum clearance to combustible material is
zero.
COMBUSTION AIR
TERMINAL
Extend vent/combustion air piping to maintain
minimum vertical (‘X’) and minimum horizontal (‘Y’)
distance of 12 in. (300 mm) [18 in. (460 mm) Canada]
from roof surface. Allow additional vertical (‘X’)
distance for expected snow accumulation.
