These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontal
run is 20 feet (6.1m). The maximum allowable vertical vent length is 40 feet (12.2m). The maximum number of
vent connections is two horizontally or three vertically (excluding the appliance and the air terminal connections)
when using fl exible venting.
Horizontal runs may have a 0" (0mm) rise per foot/meter however for optimum performance it is recommended
that all horizontal runs have a minimum 1/4" (21mm) rise per foot/meter using fl exible venting. For safe and
proper operation of the appliance, follow the venting instructions exactly.
A terminal shall not terminate directly above a sidewalk or paved driveway which is located between two single
family dwellings and serves both dwellings. Local codes or regulations may require different clearances.
Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows. Keep it pulled tight. A 1¼"
(31.8mm) air gap all around between the inner liner and outer liner is required for safe operation.
