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 5" (127mm) exhaust / 8" (203.2mm) 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.
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.
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 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.
When using Wolf Steel venting components, use only approved Wolf Steel rigid / fl exible components with the
This template must be used in conjunction with templates 7.2.1 or 7.2.2, depending on termina-
following termination kits: wall terminal kit GD422-1, GD422R-2, or 1/12 to 7/12 pitch roof terminal kit GD410,
tion shape (i.e. round, or round and square). See appropriate templates folder.
8/12 to 12/12 roof terminal kit GD411, fl at roof terminal kit GD412 or periscope kit GD401 (for wall penetration
below grade). With fl exible 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 fl ame appearance and appliance performance, keep the vent length and number of elbows to
a minimum.
All vent measurements start at the base of the air collar of the appliance.
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)
