Bracket to hold the Tee to the rear of the
appliance is mandatory. If it is desired to
mount the Tee Support to the rear of the
stove, obtain approval from the manufacturer
of the stove before drilling, tapping, or
performing any other alterations to the
appliance.
10. Connect the appliance to the coupling
on the bottom of the Flex Pipe, by twisting
to the locked position. Push the appliance
into the fireplace to its final resting place. Go
to the top of the chimney and pull the vent
system up to it’s desired height.
11. For the termination of the pellet vent,
you will use a Tall Cone Flashing, and a Storm
Collar. This will require 14" of pipe above the
top of the masonry chimney. Pull the pipe up
through the flashing to the desired height.
Mark where the Storm Collar will go. Slip the
Storm Collar down over the pipe, and affix
it to the pipe with a 1/4”long stainless steel
sheet metal screw. (Figures 13 & 14). The
Storm Collar will then support the entire vent
system. Install the Cap. Seal the joint at the
Storm Collar, and any other joints or seams
which may appear suspect. Figure 15 shows
a Tall Cone Flashing modified to fit a chimney
where the tile liner protrudes above the
masonry, as another alternate termination
technique. This completes the masonry
installation.
INSTALLATION THROUgH
SIDE OF MASONRY CHIMNEY
1. Set the appliance in its final location
and mark the center of the hole where the
pipe is to penetrate the masonry chimney
(Figure 16). Insure that you comply with the
manufacturer’s specifications in regards to
clearance and distances from combustible
surfaces.
2. The pellet vent system is assembled
essentially the same as previously described
for installation in an existing masonry
chimney with the exceptions listed:
A. No Flex Pipe is required, unless the
