Rear Venting Graph - Montigo H34DF Installation & Maintenance Manual

Rear 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 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 60" and the horizontal
run to the wall flange of the vent termination is 24", this would be an
acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 78" and the horizontal
run to the wall flange of the vent termination is 60", this would be an
acceptable installation
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 60" and the
horizontal run to the wall flange of the vent termination is 120", this
would NOT be an acceptable installation.
