WARNING
• Risk of fi re. Maintain specifi ed air space clearances to vent pipe and appliance.
• If venting is included with spacers, 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.
NOTE: If for any reason the vent air intake system is disassembled; reinstall per the instructions
provided for the initial installation.
NOTE: 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 rigid / fl exible components with the
following termination kits: wall terminal kit GD-222, GD-222R, or 1/12 to 7/12 pitch roof terminal kit GD-110,
8/12 to 12/12 roof terminal kit GD-111, fl at roof terminal kit GD-112 or periscope kit GD-201 (for wall penetration
below grade). With fl exible venting, in conjunction with the various terminations, use either the 5 foot (1.5m) vent
kit GD-220 or the 10 foot (3.1m) vent kit GD-330. For stoves only: wall terminal kit GD-175 (venting included).
For optimum fl ame appearance and appliance performance, keep the vent length and number of elbows to a

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:
The minimum clearances from the top of the horizontal vent pipe to combustible materials may be reduced from
3” (76mm) to 1” (25mm) in those installations with a minimum 38” (96.5cm) vertical vent rise made immediately
off the fireplace collar.
