Installation
Top Vent Venting Runs
For the ME38-ODV-2 Top Vent, there are two types of installations:
A) Through-The-Wall Installations and B) Vertical (Through-The-Roof)
Installations.
A) Through-The-Wall Installations
Before you install any venting, you must determine whether the
venting run will be acceptable. Unacceptable venting can affect the
fireplace's combustion.
The Venting Graph
Measure the vertical height from the fireplace hearth to the centre of
the termination and the horizontal run from the from the fireplace flue
collar to the wall flange of the termination. Plot on the Venting Graph
(Fig. 7) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" and the
horizontal run to the wall flange of the vent termination
is 36", this would be an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 90" and the
horizontal run to the wall flange of the vent termination
is 120", this would be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is
72" and the horizontal run to the wall flange of the vent
termination is 84", this would nOt be an accept-
able installation.

passes through combustible construction.
Heat Shields
Due to high flue temperatures, heat shields are required on all 38
Series Modular Direct Vent installations (except those with vertical
terminations) at the point where the vent-
ing connects to the termination. With
the heat shield, vent clearances can
be maintained at 1".

NOTES: All dimension lengths for vertical or horizontal runs are
measured from center of the vent pipe.
Venting runs must fall within the limits set by the vent-
ing graph (see Figure 7).
