3.1 VENTING LENGTHS AND COMPONENTS
FOR 4” / 7” (USE REDUCER KIT A4758AK TO TRANSITION FROM 5” / 8” TO 4” /7” VENTING)
When using Wolf Steel 4"/7" 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.
When using Wolf Steel 5"/8" 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.
Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent or Metal-Fab venting
components. Minimum and maximum vent lengths, for both horizontal and vertical installations, clearances from
vent pipes to combustibles and air terminal locations as set out in this manual apply to all vent systems and must
be adhered to. For Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent and Metal-Fab follow the
installation procedure provided with the venting components.
A starter adaptor must be used with the following vent systems and may be purchased from the corresponding
supplier:
For Simpson Dura-Vent, Selkirk Direct Temp, American Metal Amerivent and Metal-Fab follow the installation
procedure found on the website for your venting supplier.
For vent systems that provide seals on the inner exhaust flue, only the outer air intake joints must be sealed using a red high
temperature silicone (RTV). This same sealant may be used on both the inner exhaust and outer intake vent pipe joints of all
other approved vent systems except for the exhaust vent pipe connection to the appliance flue collar which must be sealed
using the black high temperature sealant Mill Pac.
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.
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 flexible 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. When terminating horizontally, the maximum
allowable horizontal run is 20 feet (6.1m). When terminating vertically, 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” rise per foot or 21mm per 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 dwell-
ings 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.
