1. 

Move the fi replace into position. Measure the vent length required between terminal and fi replace taking into account the 

additional length needed for the fi nished wall surface and any 1¼" overlaps between venting components.

2. 

Apply high temperature sealant W573-0007 (not supplied) to the outer edge of the 4" inner collar of the fi replace.  Attach 

the fi rst 4" rigid vent pipe component and secure using 3 self tapping screws. Repeat using the 7" rigid vent pipe.  

3. 

Holding the air terminal (lettering in an upright, readable position), insert into both vent pipes with a twisting motion to 

ensure that both the terminal sleeves engage into the vent pipes and the sealant. Secure the terminal to the exterior wall 
and make weather tight by sealing with caulking (not supplied). 

 

The air terminal mounting plate may be recessed into the exterior wall or siding by 1½", the depth of the return fl ange.

HORIZONTAL AIR TERMINAL INSTALLATION

A 45° corner installation can have 0" rise between the fi replace combustion air collar and the air 
terminal. 

 

In this case, vent lengths must be kept to a maximum of 24". For longer vent lengths, a 

minimum vertical rise of 24" is required.

1. 

Follow the instructions for "Horizontal Air Terminal Installations". 

2. 

Continue adding components alternating 4" rigid vent pipe and 7" rigid vent pipe. Ensure that all 4" 

rigid vent pipe and elbows have suffi cient vent spacers attached and each  component is sealed and 
securely fastened to the one prior. Attach the 4" telescopic sleeve to the vent run. Repeat using a 7" telescopic 
sleeve. Seal and secure as before. To facilitate completion, attach 4" and 7" couplers to the air terminal. 

3.  

Install the air terminal. 

See item 3, Horizontal Air Terminal Installation.

 Extend the 4" telescopic sleeve; apply 

sealant and connect to the air terminal assembly. Fasten with self tapping screws. Repeat using the 7" telescopic sleeve.

NOTE:

 

Before attaching elbows to the collars on the back of the 

fi

 replace, 1½" will need to be trimmed off the 4" 

collar. 

REAR VENT APPLICATION:

 Attach 4" and 7" elbows to the fi replace. Secure with 3 screws and 

seal the joints and screw heads using high temperature sealant. Proceed to step 1 below.

TOP VENT APPLICATION: 

1. 

Move the fi replace into position.

2. 

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

FIGURE 33.

 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. 

3.

 Apply high temperature sealant W573-0007 (not supplied) to the outer edge of the inner sleeve 

of the air terminal. Slip a 4" diameter coupler a minimum of 2" over the sleeve and secure using 
3 screws. 

4

.

 Apply high temperature sealant W573-0002 (not supplied) to the outer edge of the of the outside 

sleeve of the air terminal connector. Slip a 7" diameter coupler over the sleeve and secure as 
before. Trim the 7" coupler even with the 4" coupler end.

5

.

 Thread the air terminal connector / vent pipe assembly down through the roof support and attach, 

ensuring that a minimum 16" of air terminal connector will penetrate the roof when fastened. 

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. 

6.

 Remove nails from the shingles, above and to the sides of the chimney. Place the fl ashing over the air 

terminal connector and slide it underneath the sides and upper edge of the shingles. Ensure that the air 
terminal connector is properly centered 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.

7.

 

Apply a heavy bead of waterproof caulking 2" above the fl ashing. 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 connector and the collar is achieved.

8.

  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 sleeve.

9. 

REAR VENT APPLICATION: 

Run a bead of high temperature sealant W573-0007 (not supplied) around the outside of 

the 4" elbow. Pull the adjustable pipe a minimum 2" onto the elbow. Secure with 3 screws. Repeat with the 7" telescopic 
sleeve.

TOP VENT APPLICATION: 

Run a bead of high temperature sealant W573-0007 (not supplied) around the outside of the 

4" collar on the fi replace. Pull the adjustable pipe a minimum of 2" onto the collar. Secure with 3 screws. Repeat with the 7" 
telescopic sleeve.

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 fi lling up the 1" air space around the pipe.
