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 American
Hearth 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 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 your American Hearth Dealer
for replacement parts.

DVVK-4F FLEX VENT INSTRUCTIONS
vertical Through the Roof Applications (Figure 46)
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.
