ME38-ODV-2 Homefire
B. Multi-Elbow Installations
For more diffiicult installation situations, the ME38-ODV-2 Rear Vent
may be installed with two - 90° elbows and up to 15' of horizontal
run. If using this installation option, you must adhere to the following
guidelines:
the first 90° elbow must be placed directly on the flue collar
you must have a minimum vertical lift of 50" (measured from the
hearth)
your vent run must fall within the limits set by Figure 18a
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. 18a) 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 126", this would be an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is
78" and the horizontal run to the wall flange of the vent
termination is 108", this would nOt be an accept-
able installation.
