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 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. 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” (91.4cm) 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” (144.8cm). When terminating vertically, the vertical rise is a minimum 36” (91.4cm) 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 saf
e
operation. Use a fi restop when penetrating interior walls, fl oor or ceiling.
