•  Overlap pipe slip sections at least 1-1/2 inches.

•  Use pilot holes for screws.

•  Screws must not exceed one inch long.

•  Pipe may separate if not properly joined.

Insert the inner fl ue of section A into the fl ared  inner  fl ue  of 
section B.

Start the outer fl ue of section A over the outer fl ue 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.

To attach the fi rst pipe section to the collars, slide the male end of 
the inner vent of the pipe section over the inner collar on the fi rebox 
assembly. At the same time, slide the outer fl ue 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 section to confi rm it has completely locked into place.

 Make sure that the  seams are not aligned to prevent unintentional disconnection.

Once both inner and outer fl ues 
are started, press section A onto 
section B fi rmly 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 
Figure 8.4). Tug slightly on sec-
tion A to confi rm it has completely 
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 
fl ue 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.
