INSTALLATION

WALL AND CEILING PROTECTION

For optimum performance it is recommended that all horizontal runs have a minimum ¼ inch rise per foot using flexible venting.

For safe and proper operation of the fireplace, follow the venting instructions exactly.

HORIZONTAL TERMINATION: A clearance to combus- tibles of 2" must be maintained during the first 24" of venting when penetrating combustible walls. The firestop spacer (GD-500.106 ) supplied with the unit should be used to maintain this clearance. The first two feet of outer 7" diameter vent pipe, from the appliance must be wrapped in the 1 inch thick insulation sleeve (supplied) as well as having a 1 inch air gap. Thereafter a 1" clearance to combustibles may be maintained us- ing firestop spacer (GD-500.96 for use with flexible vent- ing or GD-500.136 for use with rigid venting).

VERTICAL TERMINATION: Only a clearance to com- bustibles of 1" all around the vent pipe is required.

mined the air terminal location,
cut and frame a hole in an exterior
wall with a minimum square or
round opening of 11½"*. (As an
alternative to framing, a vent pipe
shield may be installed, ensuring
a 1" clearance to combustibles.

Mark and cut the vent pipe shield to the determined depth of the combustible wall. Apply a bead of caulking (not sup- plied) to the framework or to the shield plate (in the case of a finished wall) and secure the shield through the opening to the interior wall. The final location of the vent pipe shield should maintain the required clearance to the 7" vent pipe / liner. Do not fill this cavity with any type of material. Apply a bead of caulking all around and place a firestop spacer over the vent shield to restrict cold air from being drawn into the room or around the fireplace. Ensure that both spacer and shield maintain the required clearance to combustibles. Once the vent pipe / liner is installed in its final position, apply sealant between the pipe / liner and the firestop spacer.

VERTICAL INSTALLATION

This application occurs when venting through a

FIGURE 15 roof. Installation kits for various roof pitches are available from your Na- poleon dealer. See Ac- cessories to order the specific kit required.

1. Determine the air ter- minal location, cut and frame 9½ inch open-

ings in the ceiling and the roof to provide the minimum clearance between the fireplace pipe / liner and any com- bustible material. Try to center the exhaust pipe location midway between two joist to prevent having to cut them. Use a plumb bob to line up the center of the openings.

DO NOT FILLTHIS SPACE WITHANY TYPE OF MATERIAL.

A vent pipe shield will prevent any materials such as insulation,

from filling up the 1" FIGURE 16 air space around the

pipe. Nail headers be- tween the joist for ex- tra support.

2.Apply a bead of caulking (not supplied) to the framework or to the Wolf Steel vent pipe shield plate or equivalent (in the case of a finished ceiling), and secure over the open- ing in the ceiling. A firestop must be placed on the bottom of each framed opening in a roof or ceiling that the venting system passes through. Apply a bead of caulking all around and place a firestop spacer over the vent shield to restrict cold air from being drawn into the room or around the fire- place. Ensure that both spacer and shield maintain the required clearance to combustibles. Once the vent pipe / liner is installed in its final position, apply sealant between the pipe / liner and the firestop spacer.

3.In the attic, after the pipe / liner

has been installed, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will prevent any ma- terials, such as insulation, from filling up the 1" air space around the pipe.

*The 11½ inch framing dimension may be reduced to a 9½ inch opening if the vent length, from the fireplace to the framed hole, is 24 inches or greater. If not, it is rec- ommended to use a terminal extension plate, W500-0103, when mounting the air terminal.
