VERTICAL VENTING INSTALLATION
Before attaching elbows to the collars on the back of the fireplace, 1½" will need to be trimmed off the 4" collar.
REAR VENT APPLICATION: Attach 4" and 7" elbows to the fireplace. Secure with 3 screws and seal the joints and screw heads using high temperature sealant. Proceed to step 1 below.
TOP VENT APPLICATION:
1.Move the fireplace into position.
2.Fasten the roof support to the roof using the screws provided. FIGURE 30. The roof support is optional. In this case the venting is to be adequately supported using ei- ther an alternate method suitable to the authority having jurisdiction or the optional roof support.
3.Apply high temperature sealant to the outer edge of the inner sleeve of the air terminal. Slip a 4" diameter coupler a minimum of 2" over the sleeve and secure using 3 screws.

6. Remove nails from the shingles, above and to the |
sides of the chimney. Place the flashing over the air termi- |
nal and slide it underneath the sides and upper edge of |
the shingles. Ensure that the air terminal is properly |
centered within the flashing, giving a 3/4" margin all around. |
Fasten to the roof. Do NOT nail through the lower portion of |
the flashing. Make |
Where possible, cover the sides and top edges of the flash- |
ing with roofing material. |
7. Apply a heavy bead of waterproof caulking 2 inches |
above the flashing. Slide the storm collar around the air |
terminal and down to the caulking. Tighten to ensure that a |
|
is achieved. Attach the other storm collar centered between |
the air intake and air exhaust slots onto the air terminal. |
Tighten securely. Attach the rain cap. |
8. Continue adding rigid venting sections, sealing and |
securing as above. Attach a 4" collapsed telescopic pipe |
to the last section of rigid piping. Secure with screws and |
seal. Repeat using a 7" telescopic pipe. |
9. REAR VENT APPLICATION: Run a bead of high tem- |
4. Apply high temperature sealant to the outer edge of the of the outside sleeve of the air terminal. Slip a 7" diameter coupler over the sleeve and secure as before. Trim the 7" coupler even with the 4" coupler end.
5. Thread the air terminal pipe assembly down through the roof support and attach, ensuring that a minimum 16" of air terminal will penetrate the roof when fastened.
If the attic space is tight, we recommend threading the Wolf Steel vent pipe collar or equivalent loosely onto the air terminal assembly as it is passed through the attic. The air terminal must be located vertically and plumb.

the adjustable pipe a minimum 2" onto the elbow. Secure |

TOP VENT APPLICATION: Run a bead of high temperature sealant around the outside of the 4" collar on the fire- place. Pull the adjustable pipe a minimum of 2" onto the collar. Secure with 3 screws. Repeat with the 7" telescopic pipe.
10.In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will prevent any materials, such as insulation, from filling up the 1" air space around the pipe.
RESTRICTING VERTICAL VENTS
Model GD36NTR Vertical Terminal only:
Vertical terminations running longer than 15 feet may display a very active flame. If this appearance is not desirable, the vent exit must be restricted using restrictor plate kit,
