Use the chart on this page to calculate vertical rises for
horizontal runs between 3 and 20 feet.
FIGURE 5.
When calculating maximum run lengths, include 10 feet
for each 90° elbow or 5 feet for each 45° elbow. (DO NOT
INCLUDE THE FIRST ELBOW DIRECTLY OFF THE UNIT.)
Only the following Napoleon Vent Kits, used in combina-
tion with each other can be used:
GD201
,
GD222
,
GD110
,
GD111
or
GD112
(Periscope, Wall
or Roof Terminals)
and
GD220
(5ft vent kit) or/and
GD330
(10ft vent kits)
VENTING OPTION #2
Use this chart to calculate vertical rise for horizontal run
between 1 foot (maximum length when the vertical rise is
at its minimum of 1 foot) and 8 feet.
FIGURES 6.
A terminal shall not terminate directly above a sidewalk
or paved driveway which is located between two sin-
gle family dwellings and serves both dwellings. Local
codes or regulations may require different clearances.
All horizontal runs must have a minimum 1 inch rise per
foot when using flexible venting components.
Do not allow the inside liner to bunch up on horizontal or
vertical runs and elbows. Keep it pulled tight. A 1¼" air
gap all around between the inner liner and outer stove
pipe is required for safe operation. Use a firestop when
penetrating interior walls, floor or ceiling.
VENTING OPTION #1
When venting, the horizontal run must be kept to a mini-
mum of 10 inches
or a maximum of 20 feet. If a 20 foot
horizontal run is required, the fireplace must have a mini-
mum vertical rise immediately off the fireplace of 57 inches.
