Combustion Air - Napoleon GDS 50 - N Installation And Operation Instruction Manual

INSTALLING FLASHING AND STORM
14
COLLAR
Remove nails from the shingles above and to the sides of
the chimney. Place the flashing over the vent pipe and slide
it underneath the sides and upper edge of the shingles.
Ensure that the vent pipe is properly centered within the
flashing, giving a 3/4" margin all around. Fasten to the roof
on the top and sides. DO NOT NAIL 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.
Apply waterproof caulk-
ing around the vent, 1"
above the top of the
flashing and push the
storm collar down into the caulking. Attach a rain cap to the
top of the last vent section.

3. Undo the bracket holding the thermodisc, turn 90° as
shown and reattach to the weld stud located on the right
air manifold side. FIGURE 31. (Do not tighten the wing nut
until burner is installed; then ensure that the switch firmly
touches the underside of the burner tray and tighten. This
enables the blower to function properly.)

base. Connect the shorter of the 2 wires to the terminal
block.

the other side of the terminal block. (The other black wire
has a 1/4" tab and is to be attached to the gas valve.)
7. Replace and re-secure the log support bracket and the
two burners ensuring that each venturi fits over the burner
orifice.

COMBUSTION AIR

ANY STOVE NEEDS AIR FOR SAFE OPERATION AND
MUST BE INSTALLED IN SUCH A WAY THAT ADEQUATE
COMBUSTION AIR IS AVAILABLE. THIS UNIT IS DE-
FIGURE 30
SIGNED TO FUNCTION USING EITHER OUTSIDE OR IN-
SIDE (ROOM) AIR.
If using outside air, connections can be made through a
hole in the floor to line up with the hole in the pedestal
base. Use a fresh air kit available through your Napoleon
Fireplace dealer or Wolf Steel Ltd. Secure the 4" diameter
aluminium liner to the hole in the base of the pedestal.
Avoid cutting away floor joist, electrical wiring or plumbing.
Seal around the outside pipe with insulation to prevent
drafts.
