8 Installing Vent Pipe
A. Assembly of Vent Sections
WARNING
Do not mix pipe, fittings or joining methods from different manufacturers.
WARNING
Fire Risk
Exhaust Fumes Risk
Impaired Performance of Appliance
•Overlap pipe slip sections at least
•Use pilot holes for screws.
•Screws must not exceed one inch long.
•Pipe may separate if not properly joined.
Attaching Vent to the Firebox Assembly
To attach the first pipe section to the collars, slide the male end of the inner vent of the pipe section over the inner collar on the firebox assembly. At the same time, slide the outer flue over the outer collar on the appliance. Push the pipe section into the appliance collar until all the lances (see Figure 8.1) have snapped in place. Tug slightly on the sec- tion to confirm it has completely locked into place.
Assembling Pipe Sections
Insert the inner flue of section A into the flared inner flue of section B.
Start the outer flue of section A over the outer flue of section B (see Figure 8.2). Note: The end of the pipe sections with the lances/tabs on it will face towards the appliance.
Once both inner and outer flues are started, press section A onto section B firmly until all lances have snapped into place. Check to make sure they have snapped together (see Figure 8.3) and the seams are not aligned (see Fig- ure 8.4). Tug slightly on section A to confirm it has com- pletely locked into place. It is acceptable to use screws no longer than 1 inch to hold outer pipe sections together. If predrilling holes, do NOT penetrate inner pipe.
For 90° and 45° elbows that are changing the vent direction from horizontal to vertical, one screw minimum should be put in the outer flue at the horizontal elbow joint to prevent the elbow from rotating. Use screws no longer than 1 inch. If predrilling screw holes, do NOT penetrate inner pipe.
