FIGURE 1
All horizontal runs must have a 1 inch rise per foot in all
cases using Napoleon flexible venting components.
Horizontal runs can have a 0 inch rise per foot using
Simpson Dura-Vent components or Napoleon rigid vent-
ing components.
Provide a means for visually checking the vent connec-
tion to the fireplace after the fireplace is installed.
Do not allow the inside liner to bunch up on horizontal or
vertical runs and elbows. Keep it pulled tight. A 1¼" air
gap between the inner and outer liner all around is re-
quired for safe operation.
For safe and proper operation of the fireplace follow the
venting instruction exactly.
Deviation from the minimum vertical vent length can cre-
ate difficulty in burner start-up and/or carboning.
VENTING LENGTHS
Use only Napoleon or Simpson Dura-Vent Model DV-GS
venting components. Minimum and maximum vent lengths,
for both horizontal and vertical installations, and air termi-
nal locations for either system are set out in this manual
and must be adhered to.
When using Napoleon venting components, use only the
following vent kits: WALL TERMINAL KIT GD222, or 1/12 TO
7/12 PITCH ROOF TERMINAL KIT GD110, 8/12 TO 12/12
ROOF TERMINAL KIT GD111, FLAT ROOF TERMINAL KIT
GD112 or PERISCOPE KIT GD201 (for wall penetration
below grade) in conjunction with the various terminations,
use either the 5 foot vent kit GD220 or the 10 foot vent kit
GD330. For Simpson Dura-Vent, follow the installation pro-
cedure provided with the venting components.
These vent kits allow for either horizontal or vertical venting
of the fireplace. The maximum number of 4" flexible con-
nections is three horizontally or four vertically (excluding
the fireplace and the air terminal connections).
For optimum flame appearance and fireplace performance,
keep the vent length and number of elbows to a minimum.
WS-415-091 / 06.26.00
If vertical rises greater than 57 inches are necessary,
the increased rise must be deducted from the horizontal
run. (figures 3, and 5a-c.)
The first 2 feet of outer 7 inch diameter vent pipe from
the appliance (or from the unit to the first firestop spacer
if under 2 feet) must be wrapped in the 1 inch thick insu-
lation sleeve (supplied) as well as having a 1 inch air
gap.
Use a firestop when penetrating interior walls, floor or
ceiling.
The
fireplace must be installed against finished walls. Do
not install against a vapour barrier or exposed insulation.
Vent lengths that pass through unheated spaces (attics,
garages, crawl spaces) should be insulated with the in-
sulation wrapped in a protective sleeve to minimize con-
densation.
VENTING
The air terminal must remain unobstructed at all times.
Examine the air terminal at least once a year to verify that it
is unobstructed and undamaged.
When terminating vertically,
the vertical rise is a mini-
mum 34 inches and a maxi-
mum 40 feet above the fire-
place. FIGURE 2.
