22W415-0748 / 12.12.083.3.3 VERTICAL AIR TERMINAL INSTALLATIONA. Move the fireplace into position.B. 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 methodsuitable to the authority having jurisdiction or the optional roof support.C. Apply high temperature sealant W573-0007 (not supplied) to the outer edge of theinner sleeve of the air terminal. Slip the inner coupler a minimum of 2" over the sleeveand secure using 3 screws.D. Apply high temperature sealant W573-0002 (not supplied) to the outer edge of the ofthe outside sleeve of the air terminal connector. Slip the outer coupler over the sleeveand secure as before. Trim the outer coupler even with the inner coupler end.E. Thread the air terminal connector / vent pipe assembly down through the roof supportand attach, ensuring that a minimum 16" of air terminal connector will penetrate theroof when fastened. If the attic space is tight, we recommend threading the Wolf Steelvent pipe collar or equivalent loosely onto the air terminal connector / vent pipeassembly as it is passed through the attic. The air terminal connector must be locatedvertically and plumb.F. Remove nails from the shingles, above and to the sides of the chimney. Place the flashing over the air terminalconnector and slide it underneath the sides and upper edge of the shingles. Ensure that the air terminal connector isproperly centered within the flashing, giving a 3/4" margin all around. Fasten to the roof. Do NOTnail 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.G. Apply a heavy bead of waterproof caulking 2" above the flashing. Install the storm collar aroundthe air terminal and slide down to the caulking. Tighten to ensure that a weather-tight sealbetween the air terminal connector and the collar is achieved.H. Continue adding rigid venting sections, sealing and securing as above. Attach the innercollapsed telescopic sleeve to the last section of rigid piping. Secure with screws and seal.Repeat using the outer telescopic sleeve.I. Run a bead of high temperature sealant W573-0007 (not supplied) around the outside of the inner collar on the fireplace.Pull the telescopic sleeve a minimum of 2" onto the collar. Secure with 3 screws. Repeat with the outer telescopic sleeve.J. In the attic, slide the vent pipe collar down to cover up the open end of the shield and tighten. This will prevent anymaterials, such as insulation, from filling up the 1" air space around the pipe.INNER RIGIDPIPEOUTERRIGID PIPEINNER PIPEHIGHTEMPERATURESEALANTAIRTERMINALCONNECTORVENTPIPESHIELDVENTPIPECOLLAR3.4 RESTRICTING VERTICAL VENTSFLUE COLLARRESTRICTOR PLATETOP OF FIREBOXVertical terminations may display a very active flame. If thisappearance is not desirable, the vent exit must be restrictedusing restrictor plate W500-0205. This reduces the velocityof the exhaust gases, slowing down the flame pattern andcreating 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 col-lar inside the firebox. Install the plate in the desired set ofholes, then replace the screws.It is recommended to secure in the third set of holes whichcauses the greatest amount of restriction for vent lengthsbetween 15 and 30 feet.FIGURE 3.3.3jFIGURE 3.3.3aFIGURE 3.4!
