Installation
The Venting Graph: H*38DF*-ST
Measure the vertical height from the replace hearth to the centre of the
termination and the horizontal run from the replace ue collar to the wall
ange of the termination. Plot on the Venting Graph Figure 13 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 114" and the horizontal
run to the wall ange of the vent termination is 168", this would be
an acceptable installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 36" and the horizontal
run to the wall ange of the vent termination is 84", this would
NOT be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 60" and
the horizontal run to the wall ange of the vent termination is 144",
this would NOT be an acceptable installation.

Section 3-3-1: VENTING LAYOUT: Wall mounted termination.
Selection of components and details of venting layout should adhere
to the following guidelines:
 Vent terminations must not be recessed in walls or siding.
 All through-the–wall terminations within 3’ of the replace must
have a Montigo Heat Shield (RHS101) installed. See Section
3-3-3.
 All through-the-wall terminations beyond 3' of the replace must
have a Montigo Heat Shield (RHS8) installed. See Section 3-3-3.
 Once the proposed venting layout has been determined refer to
Figure 13 or 14 to ensure the layout is acceptable.
Notes Wall Mounted Terminations: TOP VENT
 All measurements for vertical or horizontal runs are measured
from center of the vent pipe.
 Venting runs must fall within the limits set by the venting graph,
see Figure 13.
