minimum venting requirements
EN
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 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 flexible components with the wall
terminal kit GD422R-2, 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.
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" (21mm) rise per foot/meter using flexible
venting. For safe and proper operation of the appliance, follow the venting instructions exactly.
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. 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.
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.
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 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. See 4/7" vent clearance to combustibles section for specific venting
parameters. See detailed instructions
