Venting Installation Tips
Support piping:
• horizontal runs - at least every 5 ft
• vertical runs - use braces
• under or near elbows
CAUTION: The silicone vent gaskets must be prop-
erly reinstalled to prevent flue gas leakage. Replace
any torn or worn vent gaskets.
WARNING: Examine the venting system at least
once a year. Check all joints and vent pipe
connections for tightness, corrosion or deterioration.
6. DO NOT terminate vent closer than 5 ft below roof
overhang.
7. The vent terminal requires a 12 in. vent terminal
clearance from the wall.
8. Terminate vent at least 1 ft above grade, including
normal snow line.
9. Multiple direct vent installations require a 4 ft
clearance between the ends of vent caps located
on the same horizontal plane.
