3.0 venting

RISK OF FIRE, MAINTAIN SPECIFIED AIR SPACE CLEARANCES TO VENT PIPE AND APPLIANCE.
IF VENTING IS INCLUDED WITH SPACERS THE VENT SYSTEM MUST BE SUPPORTED EVERY 3FT
(0.9m) FOR BOTH VERTICAL AND HORIZONTAL RUNS. USE SUPPORTS OR EQUIVALENT
NON-COMBUSTIBLE STRAPPING TO MAINTAIN THE REQUIRED CLEARANCE FROM
COMBUSTIBLES. USE WOLF STEEL LTD. SUPPORT RING ASSEMBLY W010-0370 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 SPACERS MUST NOT BE REMOVED.
THIS APPLIANCE USES A 4" (102mm) EXHAUST / 7" (178mm) AIR INTAKE VENT PIPE SYSTEM.
For safe and proper operation of the appliance follow the venting instruction 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 (204°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.

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,
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:
VENT
MANUFACTURER
Duravent
Amerivent
Direct Temp
SuperSeal
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 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
