WARNING
•
Risk of fi re. Maintain specifi ed air space clearances to vent pipe and appliance.
•
The vent system must be supported every 3’(0.9m) for both vertical and horizontal runs. Use support ring assembly W010-
0067 or equivalent non-combustible strapping to maintain the minimum clearance to combustibles for both vertical and
horizontal runs. Spacers are attached to the inner pipe at predetermined intervals to maintain an even air gap to the outer
pipe. This gap is required for safe operation. A spacer is required at the start, middle, and end of each elbow to ensure this
gap is maintained. These spaces must not be removed.
This appliance uses a 4” (102mm) exhaust / 7” (178mm) air intake vent pipe system. Refer to the section applicable
to your installation.
For safe and proper operation of the appliance, follow the venting instructions exactly. Deviation from the minimum vertical
vent length can create diffi culty in burner start-up and/or carboning. Under extreme vent confi gurations, allow several minutes
(5-15) for the fl ame to stabilize after ignition. Although not a requirement, it is recommended for vent lengths that pass through
unheated spaces (attics, garages, crawl spaces) be insulated with the insulation wrapped in a protective sleeve to minimize
condensation. Provide a means for visually checking the vent connection to the appliance after the appliance is installed. Use a
fi restop, vent pipe shield or attic insulation shield when penetrating interior walls, fl oor or ceiling.
The vent terminal may be painted with a high temperature paint to match exterior colours. Use an outdoor paint suitable for
400°F (200°C). Application and performance of paint is the consumer’s responsibility. Spot testing is recommended.
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 or on the website for your venting supplier.
A starter adaptor must be used with the following vent systems and may be purchased from the corresponding supplier:
note:
If for any reason the vent air intake system is disassembled, re-install per the instructions provided for the initial installation.
This appliance must be installed with a continuous connection of exhaust and air intake vent pipes. Utilizing alternate
constructions such as a chimney as part of the vent system is not permitted.

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 termination kits: wall terminal kit

(for wall penetration below grade) in conjunction with
the appropriate venting components.
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.
Horizontal runs may have a 0” rise per foot or 0mm rise per meter however for optimum performance it is recommended
that all horizontal runs have a minimum 1/4” rise per foot or 21mm rise per meter 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.
