Top Vent Venting Runs - Montigo HR38DF Installation, Operation & Maintenance Manual

H38DF Series Gas Fireplace

Top Vent Venting Runs

For the H38DF 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 fireplace flue collar to the wall
flange of the termination. Plot on the Venting Graph (Fig. 9a) with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
H38DF & HR38DF
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal run to
the wall flange of the vent termination is 180", this would be an accept-
able installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 60" and the horizontal run to
the wall flange of the vent termination is 72", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 60" and the hori-
zontal run to the wall flange of the vent termination is 144", this would
NOT be an acceptable installation.
Power Vent models, EDVPV47
LDVPV47, EDVRSPV47, and ED-
VWSPV47 to be used within the grey
shaded area of graph. (See BELOW for
applicable Product information).

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 96" and the horizontal run to
the wall flange of the vent termination is 126", this would be an acceptable
installation.

Available Top Vent Components
The following venting components are available for the H38DF-Series
Top Vent:
A - TerminationP
B - Stucco Kits
C - Flex Sections
D - Rigid
Sections
E - Elbows
NOTES: All dimension lengths for vertical or horizontal runs are
measured from centre of the vent pipe.
Venting runs must fall within the limits set by the venting
graph (see Figures 9a & 9b).
Example 1:
For our shortest venting configuration use components A and E (see
Figure 10).
Important:
An inspection of the explosion relief flappers and door must be
made prior to lighting the fireplace. This will ensure the door gas-
keting material will provide an adequate seal during operation.
