Installation
Top Vent Venting Runs
For the C42-DV 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 termina-
tion is 84", this would NOT be an acceptable installation.

Figure 8. Heat Shield. Install by sliding over the vent pipe
where it passes through combustible construction.
Heat Shields
Due to high flue temperatures, heat shield are required on all C42-DV
installations (except those with vertical terminations) at the point where
the venting connects to the termination.
With the heat shield, vent clearances
can be maintained at 1".

Venting runs must fall within the limits set by the
venting graph (see Figure 7).
