3.1 VENTING LENGTHS AND COMPONENTS
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, and air terminal
locations for either system are set out in this manual 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
fl
ue, 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
fl
ue collar which must
be sealed using the black high temperature sealant Mill Pac. High temperature sealant must be ordered separately.
When using Wolf Steel venting components, use only approved Wolf Steel rigid /
fl
exible components with the following
termination kits: wall terminal kit
GD222R
, or 1/12 to 7/12 pitch roof terminal kit
GD110
, 8/12 to 12/12 roof terminal kit
GD111
,
fl
at roof terminal kit
GD112
or periscope kit
GD201
(for wall penetration below grade). With
fl
exible venting, in
conjunction with the various terminations, use either the 5 foot vent kit
GD220
or the 10 foot vent kit
GD330
.
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.
Horizontal runs may have a 0” rise per foot however for optimum performance it is recommended that all horizontal
runs have a minimum 1” rise per foot using
fl
exible 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” air gap
all around between the inner liner and outer liner is required for safe operation.
