EXTENDED HORIZONTAL AND CORNER AIR TERMINAL INSTALLATION
1. Follow the instructions for "Horizontal Air Terminal Installations", items 1 to 3. | FIGURE 26 |
2. Continue adding components alternating flexible and rigid vent pipes. Ensure that all 4" |
|
flexible vent pipes and elbows have sufficient vent spacers attached and each component is |
|
securely fastened to the one prior. Attach the 4" telescopic sleeve to the vent run. |
|
Repeat using a 7" telescopic sleeve. Secure and seal as before. To facilitate completion, attach |
|
4" and 7" couplers to the air terminal. |
|
3. Install the air terminal. See item 3 of the Horizontal Air Terminal Installation. Extend the |
|
4" telescopic sleeve; connect to the air terminal assembly. Fasten with self tapping screws |
|
and seal. Repeat using the 7" telescopic sleeve. |

VERTICAL VENTING INSTALLATION
1. Fasten the roof support to the roof using the screws | FIGURE 27 |
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 jurisdiction or the optional roof |
|
support. |

4. Thread the air terminal connector / vent pipe 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 penetrates the roof.
If the attic space is tight, we recommend threading the Wolf Steel vent pipe collar or equivalent loosely onto the air terminal connector / vent pipe assembly as it is passed through the attic. The air terminal connector must be located vertically and plumb.

5.Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminal connector leaving a min. 3/4” of the air terminal connector showing above the top of the flashing. Slide the flashing underneath the sides and upper edge of the shingles. Ensure that the air terminal connector is properly centred 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 |

6.Aligning the seams of the terminal and air terminal connector, place the terminal over the air terminal connector making sure the inner pipe goes into the hole in the terminal. Secure with the three screws provided.
7.Apply a heavy bead of weatherproof caulking 2" above the flashing. Note: Maintain a minimum 2” space between the air inlet base and the storm collar. Install the storm collar around the air terminal and slide down to the caulking. Tighten to ensure that a

RESTRICTING VERTICAL VENTS
Vertical termination installations exiting either from the rear or the top flue collar of the stove may display a very active flame. If this appearance is not desirable, the vent exit must be restricted to reduce the velocity of the exhaust gases, thus slowing down the flame pattern and creating a more traditional gentle appearance. Remove the baffle plate from the rear wall of the firebox, exposing the flue gas outlet opening. Superimpose this outlet hole with the smaller hole on the kit restrictor plate. Secure with the two screws provided and replace the baffle plate.
