INSTALLATION

WALL AND CEILING PROTECTION

FOLLOW THE VENTING INSTRUCTIONS EXACTLY.

NOTE: REAR EXIT - A clearance to combustibles of 1" at the bottom of the vent and 2" at the top must be maintained during the first 12" of venting when penetrating combustible walls. The firestop spacer (W615-0044) supplied with the unit should be used to maintain this clearance. Thereafter a 1" clearance to combustibles may be maintained using firestop spacer (W500-0096).

TOP EXIT - Only a clearance to combustibles of 1" all around the vent pipe is required.

HORIZONTAL INSTALLATION

This application occurs when venting through an exterior wall. Having determined the air terminal location, cut and frame a hole in an exterior wall with a minimum opening as required. See Note above. (As an alternative to fram- ing, a vent pipe shield may be in- stalled, ensuring a 1" clearance to combustibles.)

1.Mark and cut the vent pipe FIGURE 23 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. (See note above). 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.

This application occurs

 

when venting through a

roof. Installation kits for

 

various roof pitches are

 

available from your Napo-

 

leon dealer. See Accesso-

 

ries to order the specific

 

kit required.

 

1.Determine the air ter- minal location, cut and

frame 9½ inch openings in the ceiling and the roof to pro- vide the minimum 1 inch clearance between the fireplace pipe / liner and any combustible 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 FILL THIS SPACE WITH ANY TYPE OF MATERIAL.

A vent pipe shield will prevent any materials such as insu-

lation, from filling up FIGURE 26 the 1" air spacearound the pipe. Nail headers between the joist for extra support.

2.Apply a bead of caulking (not supplied) to the frame- work or to the Wolf Steel vent pipe shield plate or equiva- lent (in the case of a finished ceiling), and secure over the opening 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 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 be- tween the pipe / liner and the firestop spacer.

NOTE: Two methods to ensure the air terminal covers the cut out in the wall are;

1.Where the opening in the outside wall has been cut 10½" tall to provide the 2" clearance from the vent pipe, terminal extension plate W500-0103 must be used to cover the opening.

2.The first 12" of vent pipe must have a 2" clearance to combustible material when the vent pipe exits off the back of the fireplace. This applies to any finishing material or insulation in the wall that the vent pipe passes through within that 12". The clearance from the top of the vent pipe to the combustible material on the outside surface of the wall only requires a 1" clearance from the vent pipe.
