HORIZONTAL AIR TERMINAL INSTALLATION

1.Stretch the exhaust vent pipe to the required length taking into account the additional length needed for the fi nished wall surface. Slip the vent pipe a minimum of 2" over the inner sleeve of the air terminal and secure with 3 #8 screws. Apply a heavy bead of the high temperature sealant W573-0002 (not supplied).

2.Using the air intake vent pipe, slide over the outer combustion air sleeve of the air terminal and secure with 3 #8 screws. Seal as

before.

through the fi restop maintaining the required clearance to combus- tibles. Holding the air terminal (let- tering in an upright, readable position),

secure to the exterior wall and make weather tight by sealing with caulking (not supplied).

4.Apply a heavy bead of high temperature sealant W573-0007 (not supplied) to the outside of the 4" inner collar of the fi replace approxi- mately 1" from the end. Slide the fl exible vent pipe a minimum of 2" over the fi replace vent collar and secure with 3 #8 screws.

5.Using the air intake vent pipe, slide over the fi replace combustion air collar and secure with 3 #8 screws. Seal with high temperature sealant W573-0002 (not supplied).

6.If more fl exible vent pipe needs to be used to reach the fi replace, coupler them together as illustrated in Figure 59. The vent system must be supported approximately every 3 feet for both vertical and

horizontal runs. Use noncombustible strapping to maintain the minimum 1" clearance to combustibles.

5.Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminal and slide it under- neath the sides and upper edge of the shingles. Ensure that the air terminal is properly centred within the fl ashing, giving a 3/4" margin all around. Fasten to the roof. Do not nail through the lower portion of the fl ashing. Make weather-tight by sealing with caulking. Where possible, cover the sides and top edges of the fl ashing with roofi ng

material.

6. Aligning the seams of the terminal and air terminal connec- tor, place the terminal over the air terminal connector making sure the inner pipe goes into the hole in the terminal. Secure with screws provided.

7. Apply a heavy bead of weatherproof caulking 2" above the fl ashing. Note: Maintain a minimum of 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.

8. If more vent pipe needs to be used to reach the fi replace, couple them together as illustrated. The vent system must be supported approximately every 3 feet for both vertical and horizontal runs. Use noncombustible strapping to maintain a clearance to combustibles of 1".
