Rear Vent Through-The-Wall Installations - Montigo Homefire Plus MD34-DV-2 Installation Operation & Maintenance

Rear Vent Venting Runs
The MD34-DV-2 Rear Vent has three possible installations which do
not require vertical lift:
1. Straight Installation.
The height from the hearth to the center of the termination is 26
1/8". MD34-DV-2 Rear Vent versions are supplied with an 18"
extension pipe (EXT-18) with female/female connections. For
shorter installations, cut the EXT-18 to the desired length.
For extended installations, use the EXT-18 section as supplied
for an 18" vent run.
Note: For Rear Vent models, maximum horizontal run with
no vertical lift must never exceed 18".

2. 45° Corner Installation.
Attach an EEL-45 (45° elbow) directly onto the flue collar. Cut
the EXT-18 to suit, and attach it to the EEL-45. Slide the
fireplace into position and attach to the termination.
Figure 16. Corner installation.
3. Corner Installation - 45° or less.
Use an MTO-3 termination and an MFL-1 or MFL-18 (12" or
18" compressed length) and a frame, if appropriate. Flex may
be turned to obtain desired degree of angle required but must
not exceed 45°.

Heat Shields
Due to high flue temperatures, heat shields are required on all MD34-
DV-2 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".
See Figure 8.
