venting requirements

FOR 4" / 7" (USE REDUCER KIT 4758AK TO TRANSITION FROM 5" / 8" TO 4" /7" VENTING)
When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following
termination kits: wall terminal kit GD222, GD222R, or 1/12 to 7/12 pitch roof terminal kit GD110, 8/12 to 12/12 roof terminal
kit GD111, flat roof terminal kit GD112 or periscope kit GD201 (for wall penetration below grade). With flexible venting, in
conjunction with the various terminations, use either the 5 foot (1.5m) vent kit GD220 or the 10 foot (3.1m) vent kit GD330.
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 flexible venting.
FOR 5" / 8"
When using Wolf Steel venting components, use only approved Wolf Steel rigid / flexible components with the following
termination kits: wall terminal kit GD422-1, GD422R-1, or 1/12 to 7/12 pitch roof terminal kit GD410, 8/12 to 12/12 roof
terminal kit GD411, flat roof terminal kit GD412 or periscope kit GD401 (for wall penetration below grade). With flexible
venting, in conjunction with the various terminations, use either the 5 foot (1.5m) vent kit GD420 or the 10 foot (3.1m) vent kit
GD430.
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 flexible 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" (6.4mm) rise per foot/meter using flexible 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.
