3.0 VENTING
7.1C
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 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. 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.
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 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.
When venting straight out the back to the terminal, only the rigid vent can be used. DO NOT USE FLEXIBLE
VENT. For all other venting con
fi
gurations,
fl
exible vent is acceptable.
