VENTING

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. Provide a means for visually checking the vent connection to the fi replace after the

fireplace is installed. Vent lengths that pass through unheated spaces (attic, garages, crawl spaces) should be insulated with the insulation wrapped in a protective sleeve to minimize condensation.

VENTING LENGTHS

Use only Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp or American Metal Amerivent 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 and American Metal Amerivent, follow the installation procedure provided with the venting components.

All outer pipe joints of these venting systems must be sealed using Red RTV Hight Temperature Sealant.

Wolf Steel, Simpson Dura-Vent, Selkirk Direct Temp and American Metal Amerivent venting systems must not be combined.

A starter adaptor must be used and may be purchased from the corresponding supplier:

When using Wolf Steel venting components, use only approved Wolf Steel rigid / fl exible components with the following termination kits: WALL TERMINAL KIT GD422, or 1/12 TO 7/12 PITCH ROOF TER- MINAL KIT GD410, 8/12 TO 12/12 ROOF TERMINAL KIT GD411, FLAT ROOF TERMINAL KIT GD412 or PERISCOPE KIT GD401 (for wall penetration below grade). With fl exible venting, in conjunction with the various terminations, use either the 5 foot vent kit GD420 or the 10 foot vent kit GD430.

It is recommended to attach the Wolf Steel 45º rigid adaptor directly to the unit when terminating horizontally off the back of the unit. This must be done before attaching the desired vent system. Once this transition has been made, venting systems must not be combined.

These vent kits allow for either horizontal or vertical venting of the fireplace. FIGURES 3 & 4. The maximum allowable horizontal run is 20 feet. The maximum allowable vertical vent length is 40 feet. The maximum number of 5" vent connections is two horizontally or three vertically (excluding the fi replace and the air terminal connections) when using aluminium fl exible venting.

When terminating vertically, restrictor plate W500-0205 must be installed. (Refer to Restricting Vertical Vents).

For optimum flame appearance and fireplace performance, keep the vent length and number of elbows to a minimum.

The air terminal must remain unobstructed at all times. Ex- amine the air terminal at least once a year to verify that it is unobstructed and undamaged.

Purge all gas lines with the glass door of the fireplace removed. Assure that a continuous gas flow is at the burner before re- installing the door.

Under extreme vent configurations, allow several minutes (5-15) for the flame to stabilize after ignition.

A terminal shall not terminate directly above a sidewalk or paved driveway which is located between two single family dwellings and serves both dwellings. Local codes or regulations may require different clearances.

Do not allow the inside liner to bunch up on horizontal or ver- tical runs and elbows. Keep it pulled tight. A 1¼" air gap all around between the inner liner and outer liner is required for safe operation. Use a firestop when penetrating interior walls, floor or ceiling.

HORIZONTAL VENT SECTIONS: A minimum clearance of 2" all around the vent pipe in all horizontal runs to combustibles is required. Use fi restop spacer W010-1778 (supplied).

VERTICAL VENT SECTIONS: A minimum of 1" all around the vent pipe on all vertical runs to combustibles is required. Use fi restop spacer W500-0028 (not supplied).

Horizontal runs may have a 0" rise per foot in all cases using Wolf Steel rigid or flexible vent components or Simpson Dura-Vent, Selkirk Direct Temp or American Metal Amerivent vent components.

For optimum performance it is recommended that all horizontal runs have a 1" rise per foot when using Wolf Steel flexible vent components.
