4.2.2 VERTICAL INSTALLATION

This application occurs when venting through a roof. Installation kits for various roof pitches are available from your authorized dealer / distributor. See accessories to order specific kits required.

A. Determine the air terminal location, cut and frame a square opening as	9"	9"
illustrated in the ceiling and the roof to provide the minimum 1“ clearance
between the vent pipe and any combustible material. Try to center the vent
pipe location midway between two joists to prevent having to cut them. Use		FIRESTOP
a plumb bob to line up the center of the openings. A vent pipe shield will
	UNDERSIDE OF
prevent any materials such as insulation, from filling up the 1” air space
		JOIST
around the pipe. Nail headers between the joist for extra support.
B. 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 opening in the ceiling. A firestop must be placed on the	VENT PIPE CAULKING
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	SHIELD
the vent shield to restrict cold air from being drawn into the room or around the		VENT
fireplace. Ensure that both spacer and shield maintain the required clearance to
		PIPE
combustibles. Once the vent pipe is installed in its final position, apply sealant
		COLLAR
between the pipe and the firestop assembly.
		VENT
C. In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten.		PIPE
This will prevent any materials, such as insulation, from filling up the 1” air space around the		SHIELD
pipe.	21.1

4.2.3 HORIZONTAL AIR TERMINAL INSTALLATION - MODEL GDS28

A.Stretch the inner flex pipe to the required length taking

into account the additional length needed for the	#10x2"
finished wall surface. Slip the vent pipe a minimum of 2”	SCREWS
over the inner sleeve of the air terminal and secure with
3 #8 screws. Apply a heavy bead of the high temperature
sealant W573-0007 Mill Pac (not supplied).

B. Using the outer rigid pipe, slide over the outer combustion air sleeve of the air terminal and secure with 3 #8 screws. Seal using high temperature sealant W573-0002 (not supplied).

C. Insert the vent pipes through the firestop maintaining the required clearance to combustibles. Holding the air terminal (lettering in an upright, readable position), secure to the exterior wall and make weather tight by sealing with caulking (not supplied).

D.From inside the house, using silicone, seal between the vent pipe and the firestop. Then slide the black trim collar over the vent pipe up to the firestop.

E.If more vent pipe needs to be used to reach the appliance, couple them together as illustrated. The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use noncombustible strapping to maintain the minimum clearance to combustibles.
