How to Use the Vent Graph
The Vent Graph should be read in conjunction with the
following vent installation instructions to determine the
relationship between the vertical and horizontal dimen-
sions fo the vent system.
1. Determine the height of the center of the horizontal
vent pipe exiting through the outer wall. Using this
dimension on the Sidewall Vent Graph (Fig. 18),
locate the point intersecting with the slanted graph
line.
2. From the point of this intersection, draw a vertical
line to the bottom of the graph.
3. Select the indicated dimension, and position the
fireplace in accordance with same.
EXAMPLE
A:
If the vertical dimension from the floor of the unit is 11’
(3.4m) the horizontal run to the face of the outer wall
must not exceed 14’ (4.3m).
EXAMPLE B:
If the vertical dimension from the floor of the unit is 7’
(2.1m), the horizontal run to the face of the outer wall
must not exceed 8
¹⁄₂
’ (2.6m).
When installed as a rear vent unit this appliance may be
vented directly to a termination located on the rear wall
behind the appliance.
•
Only Vermont Castings, Majestic Products venting
components are approved to be used in these
applications (See ‘Venting Components’ listed for
different installation requirements).
•
The maximum horizontal distance between the rear
of the appliance (or end of the transition elbow in a
corner application) and the outside face of the rear
wall is 20” (508mm). (Fig. 19, 20)
•
Only one 45
°
elbow is allowed in these installations.
•
Minimum clearances between vent pipe and com-
bustible materials are as follows:
Top - 2" (51 mm)
Sides - 1" (25 mm)
Bottom - 1" (25 mm)
