USING FLEXIBLE VENT COMPONENTS
Use only approved aluminum flexible liner kits marked:
“Wolf Steel Approved Venting” as identified by the stamp only on the 10” outer liner.
For safe and proper operation of the fireplace, follow the venting instructions exactly.
All inner exhaust and outer intake vent pipe joists may be sealed using either Red RTV high temp silicone seal- ant or Black high temp Mill Pac with the exception of the fireplace exhaust flue collar which must be sealed using Mill Pac (not supplied).
HORIZONTAL AIR TERMINAL INSTALLATION
Note: Direct vent terminals shall not be recessed into a wall or siding.
1.Cut or frame a hole in an exterior wall with a minimum round or square opening of 141/2” W x 141/2” H. Secure the fi restop spacer over the opening to the interior wall.
2.Stretch the 8” diameter fl exible aluminum liner to the re- quired length taking into account the additional length needed for the finished wall surface. Slip the liner a minimum of 2” over the inner sleeve of the air terminal and secure with 6 #8 screws. Apply a heavy bead of the high temperature sealant
3.Using the 10” diameter fl exible aluminum liner, slide over the outer combustion air sleeve of the air terminal and secure with 6 #8 screws. Seal as before.

4.Insert the liners through the fi restop maintaining the required clearance to combustibles. Secure to the exterior wall and make weather tight by sealing with caulking (not supplied).
5.Apply a heavy bead of the high temperature sealant, not supplied with the unit, to the inside of the 8” liner approximately 1” from the end. Slip the liner a minimum of 2” over the fi re- place vent collar and secure with 6 #8 screws.
6.If more than one liner is run we recommend supporting every 5ft.
7.Using the 10” diameter fl exible aluminium liner, apply sealant, slide a minimum of 2” over the fi replace combustion air collar and secure with 6 #8 screws.
VERTICAL AIR TERMINAL INSTALLATION
1.Move the fi replace into position. Figure 20
2.Fasten the roof support to the roof
using the screws provided. The roof support is optional. In this case the venting is to be adequately supported using either an alternate method suitable to the authority having juris- diction or the optional roof support. (Figure 20)
3. Stretch the inner aluminum
flex liner to the required length.
Slip the liner a minimum of 2” over the inner sleeve of the air terminal connector and secure with 6 #8 screws. Seal using a heavy bead of the high temperature sealant. (Figure 21)
4.Repeat using the outer aluminum
fl ex liner. (Figure 21)
5. Thread the air terminal connector
/liner assembly down through the roof. The air terminal must be
located vertically and plumb. Attach the air terminal connector to the roof support, ensuring that the top of the air terminal is 16” above the highest point that it penetrates the
roof. (Figure 22) 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.
6. Remove nails from the shingles, above and to the sides of the
chimney. Place the fl ashing over the air terminal connector leaving a min. 3/4” of the air terminal connector showing above the top of the fl ashing. Slide the fl ashing underneath the sides and upper edge
of the shingles. Ensure that c the air terminal connector is properly centred within the
fl ashing, giving a 3/4” margin |

8.Apply a heavy bead of weatherproof caulking 2 inches above the fl ashing. Note: Maintain a minimum 2” space between the air inlet base and the storm collar. Install the storm collar around the air terminal connector and slide down to the caulking. Tighten to ensure that a
