5.2.2 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 | FIGURE 5.2.2a | |
| ||
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 |
| FIGURE 5.2.2b |
| ||
|
|
|
| ||
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. | FIGURE 5.2.2c | ||||

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. |

5.2.3 HORIZONTAL AIR TERMINAL INSTALLATION - MODEL GDS60
!WARNING
TERMINALS MUST NOT BE RECESSED INTO A WALL OR SIDING MORE THAN THE DEPTH OF THE
RETURN FLANGE OF THE MOUNTING PLATE.
A. | Stretch the inner flex pipe to the required length taking | #10x2" | FIGURE 5.2.3a |
| into account the additional length needed for the | ||
| finished wall surface. Slip the vent pipe a minimum of 2” | SCREWS | CAULKING |
| over the inner sleeve of the air terminal and secure with |
| 4"FLEX |
| 3 #8 screws. Apply a heavy bead of the high temperature |
| |
|
| PIPE | |
| sealant |
| |
|
| 7" RIGID | |
|
|
| |
B. | Using the outer rigid pipe, slide over the outer combustion air | 2" OVERLAP PIPE | |
| |||
| sleeve of the air terminal and secure with 3 #8 screws. Seal | HIGH TEMP | |
| using high temperature sealant | SEALANT | |
C.Insert the vent pipes through the firestop maintaining the required clearance to
combustibles. Holding the air terminal (lettering in an upright, | #8 X 1/2” SELF DRILLING | ||
readable position), secure to the exterior wall and make | SEALANT | SCREWS & WASHERS | |
weather tight by sealing with caulking (not supplied). | INNER COUPLER | ||
| |||
|
| OUTER COUPLER |
D.If more vent pipe needs to be used to reach the fireplace, 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.

The air terminal mounting plate may be recessed into the exterior wall or siding no greater than the depth of its
return flange. |
