VENTING
VENT LENGTHS
For safe and proper operation of the fireplace follow the venting instruction exactly.
Deviation from the minimum vertical vent length can create difficulty in burner
Provide a means for visually checking the vent connection to the fireplace after the fireplace is installed.
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.
Use only Wolf Steel, Simpson
Wolf Steel, Simpson
Follow the installation procedure provided with the venting components.
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 maybe 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 fireplace flue collar which must be sealed using the black high temperature sealant MillPac. A starter adaptor must be used and may be purchased from the corresponding supplier:

When using Napoleon® venting components, use only approved Wolf Steel Ltd. rigid / flexible vent components with the following termination kits: wall terminal kit GD222 and GD222R, 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 GD201 (for wall penetration below grade). With flexible venting, in conjunction with the various terminations, use either the 5 foot vent kit GD220 or the 10 foot vent kit GD330. These vent kits allow for either horizontal or vertical venting of the fireplace.
The maximum number of allowable 4” vent connections is three horizontally or vertically (excluding the fireplace and the air terminal connections).
For optimum flame appearance and fireplace performance, keep the vent length and number of elbows to a minimum.
Under extreme vent configurations, allow several minutes
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.
Horizontal runs may have a 0” rise per foot in all cases using Wolf Steel, Simpson
For optimum performance, it is recommended that horizontal runs have a minimum 1/4” rise per foot when using Wolf Steel, Simpson
When venting, the horizontal run must be kept to a maximum of 20 feet. If a 20 foot horizontal run is required, the fireplace must have a minimum vertical rise immediately off the fireplace of 57”. When terminating vertically, the vertical rise is a minimum 3 feet and a maximum 40 feet above the fireplace.

HORIZONTAL VENT SECTIONS: A minimum clearance of 2” all around the vent pipe on all horizontal runs to combustibles is required. Use fi restop spacer
VERTICAL VENT SECTIONS: A minimum of 1” all around the vent pipe on all vertical runs to combustibles is required except for clearances in
fireplace enclosures. Use fi restop spacer
!WARNING
* The first 2 feet of outer 7 “ diameter vent pipe from the appliance must be wrapped in the 1” thick insulation sleeve (supplied). Make sure the insulation is pulled down tight to the fi replace when installed. There after, a 2” clearance all around the vent pipe from combustible materials on all horizontal vent sections is required.
