Rear Vent, Wall Mounted Graph, H*34Df; Standard Rear Vent, (No Elbows Or Offsets); Rear Vent, Wall Mounted Termination (Two Elbows) - Montigo H34DF Installation & Maintenance Manual

notes wall Mounted Terminations: Rear Vent
All dimension lengths for vertical or horizontal runs are measured from
center of the vent pipe.
Venting runs must fall within the limits set by the venting graphs, see
Figure 16.
Fireplace must be converted to Rear Vent configuration prior to running
vent, see Figure 9 and 9a.
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 Figure 16 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.
