HORIZONTAL VENTING INSTALLATION

FOR SAFE AND PROPER OPERATION OF THE STOVE, FOLLOW THE VENTING INSTRUCTIONS EXACTLY.

ALL HORIZONTAL VENT RUNS MAY HAVE A 0" RISE

PER FOOT.

FOR OPTIMUM PERFORMANCE IT IS RECOMMENDED THAT ALL HORIZONTAL RUNS HAVE A MINIMUM

¼ INCH RISE PER FOOT.

ALL INNER EXHAUST AND OUTER INTAKE VENT PIPE JOINTS MAY BE SEALED USING EITHER RED RTV HIGH TEMP SILICONE SEALANT OR BLACK HIGH TEMP MILL PAC WITH THE EXCEPTION OF THE FIREPLACE EXHAUST FLUE COLLAR WHICH MUST BE SEALED USING MILL PAC (NOT SUPPLIED).

1.Stretch the 4" diameter aluminium flexible liner to the re- quired length taking into account the additional length needed for the finished wall surface.

Spacers are attached to the 4" inner flex liner at predetermined intervals to maintain a 1-1/4" air gap to the 7" outer stove pipe. These spacers must not be removed.

Slip a 4" diameter length of aluminium flexible liner a minimum of 2" over the inner sleeve of the air terminal. Secure to the sleeve using 3 screws. Seal the joint and screw heads using the high temperature sealant.

2.Slip the first section of 7" diameter stove pipe a minimum of 2" over the outer sleeve of the air terminal. Secure to the sleeve using 3 screws. Seal the joint and screw heads using high temperature sealant.

3.Insert the liners through the firestop / vent pipe shield. Holding the air terminal (lettering in an upright, readable position), secure to the exterior wall. Make weather tight by sealing with caulking (not supplied). The air terminal mounting plate may be recessed (up to 1½" maximum) into the exterior wall or siding.

4.If more than one length of liner needs to be used to reach the stove, couple them together as illustrated in FIGURE 21. Seal the joints using the same procedure as described above.

The vent system must be supported approximately every 10 feet along a horizontal run. Use supports or equivalent non-combustible strapping to maintain the 1" clearance from combustibles.

VERTICAL VENTING INSTALLATION

1.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 jurisdiction or the optional roof support.

2. 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 3 #8 screws. Seal using a heavy bead of the high temperature sealant.

3.Repeat using the outer aluminum flex liner.

4. 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.

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

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 weather-tight by sealing with caulking. Where possible, cover the sides and top edges of the flashing with roofing material. 6. Aligning the seams of

the terminal and air terminal connector, place the terminal over the air terminal connector

making sure the liner goes into the hole in the terminal. Secure with the three screws provided.

7.Apply a heavy bead of weatherproof caulking 2 inches 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 weather- tight seal between the air terminal and the collar is achieved.
