VERTICAL VENTING INSTALLATION

 

GAS INSTALLATION

 

1. Move the fireplace into position.

Proceed once the vent installation is complete.

2. Fasten the roof support to the roof using the screws

shut-off valve, and an 18" listed flexible gas connector.

Slip a 5" diameter coupler a minimum of 2" over the sleeve

 

and secure using 3 screws.

 

4. Apply high temperature sealant to the outer edge of the of the out- side sleeve of the air terminal. Slip a 8" diameter coupler over the sleeve and secure as before. Trim the 8" coupler even with the 5" coupler end.

5. Thread the air terminal pipe assembly down through the roof support and attach, ensuring that a minimum 16" of air terminal will penetrate the roof when fastened.

If the attic space is tight, we rec- ommend threading the Wolf Steel vent pipe collar or equivalent loosely onto the air terminal as- sembly as it is passed through the attic. The air terminal must be located vertically and plumb.

2. The access to the gas in- let is located on the right side of the outer shell.

3. To ease the connection, the shut off can be flexed out through the side of the fire- place where the connection can be made.

4.When flexing any gas line, support the gas valve so that the lines are not bent. (see Access Pg. 20).

5.Check for gas leaks by brushing on a soap and water solution. Do not use open flame.

RESTRICTING VERTICAL VENTS

6.Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminal and slide it underneath the sides and upper edge of the shingles. Ensure that the air terminal 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.

7.Apply a heavy bead of waterproof caulking 2 inches above the flashing. Slide the storm collar around the air ter- minal and down to the caulking. Tighten to ensure that a weather-tight seal between the air terminal and the collar is achieved. Attach the other storm collar centred between the air intake and air exhaust slots onto the air terminal. Tighten securely. Attach the rain cap.

8.Continue adding rigid venting sections, sealing and securing as above. Attach a 5" collapsed telescopic pipe to the last section of rigid piping. Secure with screws and seal. Repeat using a 8" telescopic pipe.

9.Run a bead of high temperature sealant around the outside of the 5" collar on the fireplace. Pull the adjustable pipe a minimum of 2" onto the collar. Secure with 3 screws. Repeat with the 8" telescopic pipe.

10.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.

RESTRICTOR PLATE

FLUE COLLAR

FIGURE 29

Vertical terminations may display a very active flame. If this appearance is not desirable, the vent exit must be restricted using restrictor plate, W500-0205. This reduces the velocity of the exhaust gases, slowing down the flame pattern and creating a more traditional appearance.

The plate has a series of holes to allow for adjustment. Remove the two screws on either side of the exhaust collar inside the firebox. Install the plate in the desired set of holes, then replace the screws.
