Part No. XG0119C
Installation
2. 45° Corner Installation.
Attach an PEL-45 (45° elbow) directly onto the flue collar. Cut the
PXT-20 to suit, and attach it to the PEL-45. Slide the fireplace into
position and attach to the termination.
Rear Vent Venting Runs
The C42-DV Rear Vent has three possible installations which do
not require vertical lift:
Heat Shields
Due to high flue temperatures, heat shields are required on all
C42-DV installations (except those with vertical terminations) at the
point where the venting connects to the termination. With the heat
shield, vent clearances can be maintained at 1". *Heat Shields are
included.
See Figure 8.
1. Straight Installation.
The height from the hearth to the center of the termination
is 31 ½". C42-DV Rear Vent versions are supplied with a 20"
extension pipe (PXT-20) with female/female connections. For
shorter installations, cut the PXT-20 to the desired length.
For extended installations, use the PXT-20 section as supplied for a
20" vent run.
Note:
For Rear Vent models, maximum horizontal run with no
vertical lift must never exceed 20".
