1.3. Exhaust Restrictor Installation
Exhaust restrictors are recommended for these verti-
cally terminated products which have excessive draft.
Exhaust restrictors will compensate for high draft and
restore visual flame height. If the vent configuration
has a total vertical of 15 ft. - 40 ft. (4.6 m - 122 m)
an exhaust restrictor may be needed. The exhaust
restrictor can be located in the manual bag.
Exhaust Restrictor Instructions:
1. Locate the center vent hole of the air passage
on the inside firebox chamber as shown in
Figure 6.
2. Center the exhaust restrictor such that the
center hole of the restrictor aligns with the center
vent hole of the air passage inside the firebox
chamber.
3. Use (2) 1/2 in. (13 mm) self-tapping screws to
secure exhaust restrictor to the firebox air pas-
sage. See Figure 7.
4. In some applications, such as those that where
the fireplace is elevated off the floor, the exhaust
restrictor may be painted but painting is not
required.
NOTICE: Before painting, contact your dealer for
information on the appropriate high temperature
paint.

A. Flue System Approvals
These models are approved to use DVP series direct
flue pipe components and terminations (see Figures 5
and8).Approvedflue systemcomponents arelabeled
for identification. This pipe is tested and listed as an
approved component of the heater. The pipe is tested
to be run inside an enclosed wall. There is no require-
ment for inspection openings at each joint within the
wall.Thereis no requiredpitch forhorizontal flue runs.
NO OTHERFLUEING SYSTEMSOR COMPONENTS
MAY BE USED.
Detailedinstallation instructionsareincluded witheach
flue termination kit and should be used in conjunction
with this Installers Guide.
Theflameandemberappearancemayvarybasedonthe
type of fuel burned and the flueing configuration used.
Identifying Flue Components
The flue systems installed on this gas heater may
include one, two, or three 90° elbow assemblies. The
relationships of vertical rise to horizontal run in flue
configurations using 90° elbows MUST BE strictly
adhered to. The rise to run relationships are shown in
theflueing drawings andtables. Referto the diagrams
on the next several pages.
This model has a 45° elbow built into it. It may be posi-
tionedtoflueeither horizontalorvertical. Dependingon
theinstallation,decide whichdirectiontheelbow should
befacing. Remove the8 screws fromthe corner cover
plate. Position the 45º elbow as desired and replace
the corner cover plate with the 8 screws.

B. Installing Flue Components
After determining which direction the 45º elbow will be
used follow flueing instructions accordingly.
• This heater requires the attachment of supplied 45º
elbow to unit before connection of flue components.
• To attach the elbow flue, the elbow cover plate must
first be removed from the unit (see Figure 18).
• The elbow can be removed from the unit by aligning
the seams of the elbow to the arrows on the
surrounding heat shield (see Figure 19).
• Position the elbow in the horizontal or the vertical
position. Snap in place with the starting collar.
• Replace the elbow cover plate aligning it with the
elbow and secure in place with the 8 screws.
• Place the rope ring around the first section of pipe
and slide it up against the cover plate.
Figure 18

NOTE: The rope ring is needed for the heat manage-
ment and to prevent cold air infiltration.

Impaired Performance of Appliance
• Overlap pipe slip sections at least 1-1/2
inches (38 mm).
• Use pilot holes for screws.
• Screws must not exceed one inch
long.
• Pipe may separate if not properly
joined.

C. Assembling Flue Components
Insert the inner flue of section A into the flared inner
flue of section B.
Start the outer flue of section A over the outer flue of
section B (see Figure 21). Note: The end of the pipe
sections with the lances/tabs on it will face towards
the appliance.
Figure 21 Figure 22
Figure 23. Seams
Note: Make sure that the seams are not aligned to
prevent unintentional disconnection.
CORRECT
INCORRECT
For elbows that are changing the flue direction, two
screws minimum should be put in the outer flue at the
joint to prevent the elbow from rotating.
A
B
Once both inner and outer flues are started, press
section A onto section B firmly until all lances have
snapped into place. Check to make sure they have
snapped together (see Figure 22) and the seams are
not aligned (see Figure 23). Tug slightly on section A
to confirm it has completely locked into place.
Note: Make sure that seams are NOT aligned to prevent
unintentional disconnection.

For Vertical Runs - One firestop is REQUIRED at the
hole in each ceiling through which the flue passes.
To install firestops for vertical runs that pass through
ceilings:
• Position a plumb bob directly over the center of the
vertical flue component.
• Mark the ceiling to establish the centerpoint of the flue.
• Drill a hole or drive a nail through this center point.
• Check the floor above for any obstructions, such as
wiring or plumbing runs.
• Reposition the heater and flue system, if necessary,
to accommodate the ceiling joists and/or obstruc-
tions.
• Cuta 10"x 10"(254 mmX254 mm)hole throughthe
ceiling, using the firestop pipe opening as a guide.
• Frame the hole with framing lumber the same size
as the ceiling joists.
To install firestops (heat shield) for horizontal runs that
pass through either interior or exterior walls:
• Cuta 10in. x12 in.(254 mmx305 mm)hole through
the wall.
Figure 24. 254 mm x 305 mm Hole and Flue Pipe
D. Install Support Brackets
Refer to Cinch Pipe and Termination Cap installation
Instructions.
E. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on
both sides of a combustible wall through which the
flue passes.
• Position the firestops on both sides of the hole
previously cut and secure the firestops with nails or
screws.
• The heat shields of the firestops MUST BE placed
towards the bottom of the firestop.
• Continue the flue run through the firestop.
Note: Model DVP-TRAP2 does not need an exterior
firestop on an exterior combustible wall. The firestop is
built into the cap.
Note: The center of the hole is 1 in. (25 mm) above the
center of the horizontal flue pipe.
Note: There must be NO INSULATION or other com-
bustibles inside the framed firestop opening.

If the area above the ceiling IS an attic, position and
secure the firestop on top of the previously framed
hole.

• The termination kit should pass through the wall
firestops from the exterior of the building.
F. Flue Termination
For Horizontal Terminations - To attach and secure
the termination to the last section of horizontal flue:
• The rear flue heat shield MUST be placed one inch
abovethe topof the fluebetween thewall shieldand
the base of the termination cap.
• One section of the heat shield is attached to the wall
shield. The other is attached to the termination cap
in the same manner.
• The heat shield sections will overlap to match the
wall thickness (depth).
• Ifthe wallthicknessdoes notallow therequired1-1/2
in. (38 mm) heat shield overlap, an extended heat
shield must be used. The extended heat shield will
need to be cut to the thickness of the wall and be
attached to the wall shield.
• The small leg in the shield rests on top of the flue to
properly space it from the pipe section (see Figure 29).
If the area above the ceiling is NOT an attic, position
and secure the ceiling firestop on the ceiling side of
the previously cut and framed hole.
