3.0 VENTING
3.1 VENTING LENGTHS AND COMPONENTS
This
fi
replaces uses 8" (203mm) exhaust / 11" (280mm) air intake vent pipe system.
Refer to the section applicable to your installation.
For safe and proper operation of the
fi
replace 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. Provide a means for visually checking the vent
connection to the
fi
replace after the
fi
replace 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. 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.
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
fi
replace
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
fl
exible components with the
following termination kits: wall terminal kit
GD622R
, or 1/12 to 7/12 pitch roof terminal kit
GD610
, 8/12 to 12/12
roof terminal kit
GD611
or
fl
at roof terminal kit
GD612
. With
fl
exible venting, in conjunction with the various
terminations, use either the 5 foot (1.5m) vent kit
GD620
or the 10 foot (3m) vent kit
GD630
.
For optimum
fl
ame appearance and
fi
replace performance, keep the vent length and number of elbows to
a minimum.
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.
The minimum allowable vertical vent length is 3 feet (0.9m) maximum allowable vertical vent length is 40 feet
(12m). The maximum number of allowable 8” (203mm) vent connections is three horizontally or vertically
(excluding the
fi
replace and the air terminal connections).
When venting, the horizontal run must be kept to a minimum of 36” (914mm) or a maximum of 20 feet (6m).
If a 20 foot (6m) horizontal run is required, the
fi
replace must have a minimum vertical rise immediately off
the
fi
replace of 57” (1448mm). When terminating vertically, the vertical rise is a minimum 36” (914mm) and a
maximum 40 feet (12m) above the
fi
replace.
For optimum performance, it is recommended that all horizontal runs have a minimum 1/4” (6mm) rise
per foot/meter. Provide a means for visually checking the vent connection to the
fi
replace after the
fi
replace is installed. Do not allow the inside liner to bunch up on horizontal or vertical runs and elbows.
Keep it pulled tight. A 3/4” (19mm) air gap between the inner and outer liner all around is required for safe
operation. Use a
fi
restop when penetrating interior walls,
fl
oor or ceiling.
