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 difficulty in burner start-up and/or carboning. Under extreme
vent configurations, allow several minutes (5-15) for the flame 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
firestop, vent pipe shield or attic insulation shield when penetrating interior walls, floor 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.
3.1 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, 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 flue, 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 flue collar
which must be sealed using the black high temperature sealant Mill Pac.
When using Wolf Steel venting components, use only approved Wolf Steel termination kits: wall terminal kit GD175
(7/12’ of venting included), or 1/12 to 7/12 pitch roof terminal kit GD110, 8/12 to 12/12 roof terminal kit GD111, flat
roof terminal kit GD112 or periscope kit GD180 (for wall penetration below grade) in conjunction with the appropriate
venting components.

For optimum flame appearance and appliance operation, keep the vent length and number of elbows to a
minimum. It is recommended that all horizontal runs have a minimum 1/4” (6.4mm) rise per foot /meter. 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. Rigid and flexible venting systems must not be combined. Different
venting manufacturers components must not be combined.
These vent kits allow for either horizontal or vertical venting of the appliance. The maximum allowable horizontal
run is 20 feet (6m). The maximum allowable vertical vent length is 40 feet (12m). The maximum number of vent
connections is two horizontally or three vertically (excluding the appliance and the air terminal connections) when
using flexible venting.

For vent configurations requiring more than one 90° elbow, the following formulas apply:
Formula 1: HT< VT
Formula 2: HT+ VT< 40 feet (12.2m)
Example:
V1= 3 FT (0.9m)
V2= 8 FT (2.4m)
VT= V1+ V2= 3 FT (0.9m ) + 8 FT (2.4m) = 11 FT (3.4m)
H1= 2.5 FT (0.8m)
H2= 2 FT (0.6m)
HR= H1+ H2= 2.5 FT (0.8m) + 2 FT (0.6m) = 4.5 FT (1.4m)
HO= .03 (three 90° elbows - 90°) = .03 (270° - 90°) = 5.4 FT (1.7m)
HT= HR+ HO= 4.5 FT (1.4m) + 5.4 FT (1.6m) = 9.9 FT (3m)
HT+ VT= 9.9 FT (3m) + 11 FT (3.4m) = 20.9 FT (6.4m)
Formula 1: HT< VT
9.9 FT (3m) <11 FT (3.4m)
Formula 2: HT+ VT< 40 FT (12.2m)
20.9 FT (6.4m) < 40 FT (12.2m)
Since both formulas are met, this vent configuration is acceptable.
