Installation
Important: Some models are not available to be
installed in a rear vent application. Please refer to the
model specications on page 2 of this manual.

Figure 21. Flex installation. (NG Models Only)
2. 45° Corner Installation.
Attach an EEL-45/PEL-45 (45° elbow) directly onto the ue collar.
Cut the EXT-18/PXT-20 to suit, and attach it to the EEL-45/PEL-45.
Slide the replace into position and attach to the termination.
3. Corner Installation — 45° or less.
Use an PTO-3 termination and an PFL-1 or PFL-2/PFL-2 (12" or 24"
compressed length) and a frame, if appropriate. Flex may be turned to
obtain desired degree of angle required but must not exceed 45°.
Note: Through the wall venting kits are also available for both
the Straight and the Corner Installation. The Kit includes a heat
sheild, a PFL-18 (f/f) exible pipe, and a termination with or without
a mounting frame.

B. Multi-Elbow Installations
For more difcult installation situations, the H42DF-O 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 rst 90° elbow must be placed directly on the ue 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 22a
Before you install any venting, you must determine whether the venting
run will be acceptable. Unacceptable venting can affect the replace's
combustion.
The Venting Graph
Measure the vertical height from the replace hearth to the centre of
the termination and the horizontal run from the replace ue collar to
the wall ange of the termination. Plot on the Venting Graph (Fig. 22a)
with an 'X'.
If the 'X' falls on or above the top boundary of the shaded area, the
installation is acceptable.
H42DF-O
Example A: (Acceptable Installation)
If the vertical dimension from the hearth is 84" and the horizontal
run to the wall ange of the vent termination is 36", this would be
an acceptable installation.
Example B: (Acceptable Installation)
If the vertical dimension from the hearth is 108" and the horizontal
run to the wall ange of the vent termination is 120", this would be
an acceptable installation.
Example C: (Unacceptable Installation)
If the vertical dimension from the oor of the replace is 72" and
the horizontal run to the wall ange of the vent termination is 84",
this would NOT be an acceptable installation.
