ARNING
Always maintain minimum clearances around vent systems. the minimum
clearance to combustibles for horizontal vent pipe are 3” at the top and 1” at
the sides and bottom of the vent system until the pipe penetrates the nearest
vertical wall (1” required). A 1” minimum clearance all around the pipe must be
maintained at outside wall and on vertical runs. Do not pack the open air spaces
with insulation or other materials. this could cause high temperatures and may
present a fire hazard.
*unless the vertical run is 7
Z\x
feet or higher (top vent units only), the clearances
for the horizontal run is 1” at the top.
