Rear Vent, Wall Mounted Termination Graph; Standard Rear Vent, (No Elbows Or Offsets); Rear Vent, Wall Mounted Termination (Two Elbows) - Montigo L52DF Installation & Maintenance Manual

L52DF* Indoor Gas Fireplace
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 15.
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 15 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 102" and the horizontal
run to the wall flange of the vent termination is 108", this would be
an acceptable installation.
Example B: (Unacceptable Installation)
If the vertical dimension from the hearth is 42" and the horizontal
run to the wall flange of the vent termination is 108",this would
nOT 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 168",
this would nOT be an acceptable installation.
Acceptable vent run
within non-shaded area.
