When installing this vent system in a chase, it is always good
building practice to insulate the chase as you would the outside
walls of your home. This is especially important for cold climate
installations. Upon completion of building your chase framing,
install the vent system by following the instructions in this manual.
Remember to build the chase large enough so that minimum
clearance of combustible materials (including insulation) to the vent
system are maintained.
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, VIB6A for
use with 6 5/8" diameter vent systems, or the VIB7A for use with
7" diameter vent systems. These are available 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 direct vent high wind
vertical top.
Please refer to the instructions included with the Air Inlet Baffle Kit
for proper installation.
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 rigid pipe 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.
vertical through the roof Applications (Figure 62)
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.
