For optimum fl ame appearance and appliance operation, keep the vent length and number of elbows to a
minimum. It is recommended that all horizontal runs have a minimum 1/4” rise per foot. The air terminal must
remain unobstructed at all times. Examine the air terminal at least once a year to verify that it is unobstructed
and undamaged. Rigid and fl exible venting systems must not be combined. Different venting manufacturers
components must not be combined.
These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontal run
is 20 feet. The maximum allowable vertical vent length is 40 feet. 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.
Deviation from the minimum vertical vent length can create diffi culty in burner start-up and/or carboning.
Use an adjustable pipe as the fi nal length of rigid piping to the stove for ease of installation.
