Installation
The Venting Graph: H*42DF*
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 13 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 72" and the horizontal run to
the wall flange of the vent termination is 66", this would be an acceptable
installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the floor of the fireplace is 72" and the
horizontal run to the wall flange of the vent termination is 108", this would
NOT be an acceptable installation.

„ For Heat Shield requirements see Section 3-3-3.
„ Once the proposed venting layout has been determined refer
to Figure 13 or 15 to ensure the layout is acceptable.
Notes Wall Mounted Terminations: TOP VENT

from center of the vent pipe.
„ Venting runs must fall within the limits set by the venting graph,
see Figure 13.
