Installation of Vertical Inlet Baffle
The vertical inlet baffle is to be used only in a completely vertical
vent installation. The vertical inlet baffle can be used when the
vertical vent rise is between 10 feet and 40 feet. To maintain the
yellow flame in the main burner, purchase Vertical Inlet baffle,
DVF-139 from your Empire Comfort Systems, Inc. distributor
or dealer.
In a vertical vent rise the rear (yellow) flame on the main burner can
be reduced due to the drawing action from the flue exhaust pipe and
the air inlet pipe. A decrease in the height or the appearance of the
yellow flame may occur when the vertical vent rise is between 10
feet and 40 feet. To enhance the yellow flame on the main burner,
the vertical inlet baffle can be attached to the Simpson Dura-Vent,
991, direct vent high wind vertical top.
Please use the following steps to install the vertical inlet
baffle.
1. Place the vertical inlet baffle over the exterior of the air inlet
openings on the Simpson Dura-Vent, 991, direct vent high wind
vertical top.
2. There are three sections of air openings on the exterior of the
air inlet pipe.
To achieve the
maximum
amount of yellow flame the vertical
inlet baffle will cover-up three sections of air openings.
To achieve the
minimum
amount of yellow flame the vertical
inlet baffle will cover-up one section of air openings.
3. Attach vertical inlet baffle to the Simpson Dura-Vent 991,
direct vent high wind vertical top with (2) 3/8" hex-head screws
provided with vertical inlet baffle.
4. Installation of vertical inlet baffle is completed.

Reassembly and Resealing Vent Pipe System
Attach vent pipe to inlet and outlet vent adaptor on fireplace in either
the vertical or horizontal position, replace horizontal and vertical
pipe lengths, elbows and horizontal or vertical termination kit.
All vent system components lock into place by sliding the concentric
pipe section with four (4) equally spaced interior beads onto the
appliance collar or previously installed component end with four
(4) equally spaced indented sections. When the internal beads of
each starting outer pipe line up, rotate pipe section clockwise 90°
(approximately 3 inches). The vent pipe is now locked together.
Continue replacing components per the vent system configuration.
Be certain that each succeeding vent component is securely fitted
and locked into the preceding component in the vent system.
Reassembly and Resealing Gas Accumulation Relief System
Glass Frame Assembly and Combustion Chamber
Whenever the glass frame assembly is pivoted open by a delayed
ignition in the main burner, the glass frame assembly gaskets and
combustion chamber must be examined by a qualified service person
for damage. All damaged gaskets on the glass frame assembly and
combustion chamber must be replaced by a qualified service person.
If damage occurs to the combustion chamber, it must be replaced
by a qualified service person. Contact Empire Comfort Systems,
Inc. for replacement parts.
Vertical Through the Roof Applications (Figure 49)
Your Gas Fireplace has been approved for:
a) Vertical installations up to 40 feet in height.
b) Two sets of 45 degree elbow offsets within these vertical
installations. From 0 to a maximum of 8 ft. a vent pipe can be
used between elbows.
c) Wall straps must be used to support offset pipe every 4'.
This application will require that you first determine the roof pitch
and use the appropriate venting components.
