For optimum flame appearance and appliance performance, keep the vent length and number of elbows to a minimum.
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 manufacturer 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.
