3.1 VENTING LENGTHS AND COMPONENTS
3.0 VENTING
7.2
THIS APPLIANCE USES A 5” EXHAUST / 8” AIR INTAKE VENT PIPE SYSTEM.
Refer to the section applicable to your installation.
For safe and proper operation of the appliance follow the venting instruction exactly. Deviation from the
minimum vertical vent length can create dif
fi
culty in burner start-up and/or carboning. Under extreme vent
con
fi
gurations, allow several minutes (5-15) for the
fl
ame to stabilize after ignition. Vent lengths that pass
through unheated spaces (attics, garages, crawl spaces) should 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.
NOTE: If for any reason the vent air intake system is disassembled; reinstall per the instructions
provided for the initial installation.

WARNING
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 3 FEET
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.
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.
