When using Wolf Steel venting components, use only approved Wolf Steel rigid / fl exible components with
the following termination kits: wall terminal kit GD-222, GD-222R, or 1/12 to 7/12 pitch roof terminal kit
GD-110, 8/12 to 12/12 roof terminal kit GD-111, fl at roof terminal kit GD-112 or periscope kit GD-201 (for
wall penetration below grade). With fl exible venting, in conjunction with the various terminations, use either
the 5 foot (1.5m) vent kit GD-220 or the 10 foot (3.1m) vent kit GD-330.
For optimum fl ame 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 (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.
