USING RIGID VENT COMPONENTS
For safe and proper operation of the fireplace, follow the venting instructions exactly.
For optimum performance, it is recommended that all horizontal runs have a minimum ¼ inch rise per foot
using rigid venting.
The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use Wolf Steel vent spacers
HORIZONTAL AIR TERMINAL INSTALLATION
1.Move the fireplace into position. Measure the vent length required between terminal and fireplace taking into account the additional length needed for the finished wall surface and any 1¼" overlaps between venting components.
2.Apply high temperature sealant to the outer edge of the 4" inner collar of the fireplace. Attach the first vent component and secure using 3 self tapping screws. Re- peat using 7" piping.
3.Holding the air terminal (lettering in an upright, read- able position), insert into both vent pipes with a twisting motion to ensure that both the terminal sleeves engage into the vent pipes and sealant. Secure the terminal to the exte- rior wall and make weather tight by sealing with caulking (not supplied).
The air terminal may be recessed into the exterior wall or siding by 1½", the depth of the return flange.

VERTICAL VENTING INSTALLATION
1.Attach 4" and 7" elbows to the stove. Apply high tem- perature sealant and secure the joints with 3 screws.
2.Move the fireplace into position.
3.Fasten the roof support to the roof using the screws provided. The roof support is optional. The venting is to be adequately supported using either an alternate method suitable to the authority having jurisdiction or the optional roof support.
4.Apply high temperature sealant to the outer edge of the inner sleeve of the air terminal. Slip a 4" diameter cou- pler over the sleeve and secure using 3 screws.
5. Apply high temperature sealant to the outer edge 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.

7.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 cen- tred 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
8.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
9.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.
10.Run a bead of high temperature sealant around the outside of the 4" elbow. Pull the adjustable pipe a mini- mum 2" onto the elbow. Secure with 3 screws. Repeat with the 7" telescopic pipe.
11.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.
