DV 42 ST See-through Gas Fireplace
rev.110308
Short Congurations:
For installations straight through the wall, use an PTO-4/-4F termination and PXT-
5 or PXT-10 to achieve the desired length. The maximum horizontal vent run with
no vertical lift is 12". See Figure 16.
Heat Shields
Due to high ue temperatures, the heat shield (RHS101) must be used on all
installations straight through the wall, at the point where the vent pipe con-
nects to the termination. With the heat shield, vent clearances can be maintained
at 1". The heat shield is not included with the replace.
Example:
A 10' section of rigid pipe and a 90° elbow may be used in conjunction with a 3 ft.
ex section (PFL-3) will, when extended in a chase, allow for a maximum horizon-
tal run of twelve and one-half feet from the center of the replace to outside wall
and a minimum of 7'6" when retracted in opposite direction. (See Figure 16.)
"D" ex sections and "E" solid sections may be used in conjunction with one
another to obtain dierent possible horizontal length installations. NOTE: Flex sec-
tion must not exceed maximum horizontal length of 3 feet, and for this application
the top clearance is to the ceiling.
Long Vent Runs:
For longer or more complex vent runs, vertical lift is required. First ensure that the
planned run is acceptable using the Vent Graph. Plan out the required components
using the chart above. You may be able to use fewer components using the chart
on Page 8.
Figure 16. Extended horizontal installation using a combination of rigid and ex
venting.
To install the heat shield, slide one section over the vent pipe on the inside of the
wall opening, with the circular portion inside the wall cavity. Screw the shield in
place over the wall opening. Install the second section on the outside of the wall
opening sliding the circular portion into the wall opening. Refer to Figure 15.
Horizontal Vent Installation
Vent systems that terminate through a wall may consist of up to seven dierent
components:
A - Termination PTO-4
PTO-4F
B - Stucco Kits MSR (stucco frame)
MOSR (stucco can)
D - Flex sections PFL-1 (12" section)
PFL-2 (24" section)
PFL-3 (36" section)
PFL-4 (48" section)
E - Rigid sections PEXT-1 (12" section)
PEXT-2 (24" section)
PEXT-3 (36" section)
PEXT-4 (48" section)
F - Extensions PXT- 5 (5" section)
PXT-10 (10" section)
G - 90° elbow PEL-90F/F
PEL-90M/M
H - Heat Shield RHS101 ( for 5"/8" venting)
I - Heat Shield RHS 8 (for Top Venting)
Installation
RHS8
NOTES: 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 graph
(see Figure 7b).
Side Vent Venting Requirements
The DV 42 ST can ONLY be rear vented as shown in Figure 15, 16, 17, 17a,
17b. The vent MUST exit the replace using a 90 degree elbow and run vertically
through the roof, etc.

and 17b.)
