Codes
High A titude Insta ations
U.L. Listed gas fireplaces are tested and approved for
elevations from 0 to 2 000 feet in the U.S.A. and from 0 to
4 500 feet in Canada.
When installing this fireplace at an elevation above 2 000
feet (in the United States) it may be necessary to decrease
the input rating by changing the existing burner orifice to a
smaller size. Input should be reduced four percent (4%) for
each 1 000 feet above sea level unless the heating value of
the gas has been reduced in which case this general rule
will not apply. To identify the proper orifice size check with
the local gas utility.
When installing this fireplace at an elevation between 2 000
and 4 500 feet (in Canada) the input rating must be reduced
by ten percent (10%).
When installing this fireplace at an elevation above 4 500
feet (in Canada) check with local authorities.
Consult your local gas utility for assistance in determining
the proper orifice for your location.

B. Installing Vent Components
1. Attach the First Vent Component to the
Starting Collars
To attach the first vent component to the starting collars
of the fireplace:
 Apply a 3/8 inch (9.5mm) bead of stove cement around
the 5 inch (127mm) fireplace starting collar.
 Make sure that the fireplace rope gasket supplied with
the fireplace seals between the first 8-5/8 inch (219mm)
vent component and the outer fireplace wrap.
 Lock the vent components into place by sliding the con-
centric pipe sections with four (4) equally spaced interior
beads into the fireplace collar or previously installed com-
ponent end with four (4) equally spaced indented sections.
 When the internal beads of each 8-5/8 inch (219mm)
outer pipe line up rotate the pipe section clockwise about
one-quarter (1/4) turn. The vent pipe is now locked together.
!
!
WARNING: ENSURE THAT THE FIBER-
GLASS R PE GASKET SUPPLIED WITH
THE FIREPLACE SEALS BETWEEN THE FIRST
VENT C MP NENT AND THE UTER FIREPLACE
WRAP.
If the installation is for a termination cap attached directly
to the fireplace skip to the sections Install Firestops and

SHIELD 570-290 AB VE THE FIRST 900 ELB W IN
THE VENTING SYSTEM.
Figure 11
To Install the Heat Shield:
1. Determine if the heat shield is required. Do so by mea-
suring the vertical distance between the top horizontal
surface of the elbow to any combustible surface above.
If the distance is more than 4 inches the heat shield is
N T required. If it is 4 inches or less the heat shield IS
REQUIRED. Install per the following steps. See Figure 11.
!
 Continue adding vent components locking each succeed-
ing component into place.
 Ensure that each succeeding vent component is secure-
ly fitted and locked into the preceding component in the
vent system.
 90° elbows may be installed and rotated to any point
around the preceding components vertical axis. If an el-
bow does not end up in a locked position with the pre-
ceding component attach with a minimum of two (2)
sheet metal screws.
Figure 12
CORRECT INCORRECT
2. Fasten the shield in place using the four pilot holes pro-
vided in the part. The shield should be oriented such that
the 13 1/8 inch dimension (longest dimension) is run-
ning in the same direction the elbow is pointing. The
shield should be centered directly above the elbow and
positioned so that it creates a 1/2 inch airspace between
the shield and the combustible surface. See Figure 12.
3. Install Support Brackets
For Horizontal Runs - The vent system must be supported
every five (5) feet of horizontal run by a horizontal pipe support.
To install support brackets for horizontal runs:
 Place the pipe supports around the vent pipe.
 Nail the pipe supports to the framing members.
Figure 13. Adding Venting Components

17
For Vertical Runs - The vent system must be supported
every eight (8) feet (2.4m) above the fireplace flue outlet by
wall brackets.
To install support brackets for vertical runs:
 Attach wall brackets to the vent pipe and secure the wall
bracket to the framing members with nails or screws.
Figure 14. Installing Support Brackets
4. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.
NOTE: Model DVK-01TRD does not need an exterior
firesto on an exterior combustible wall.
To install firestops for horizontal runs that pass through
either interior or exterior walls:
 Cut a 12-inch by 12-inch (305mm X 305mm) hole through
the wall.
NOTE: The center of the hole is one (1) inch (25.4mm)
above the center of the horizontal vent i e.
 Position the firestops on both sides of the hole previ-
ously cut and secure the firestops with nails or screws.
 The heat shields of the firestops MUST BE placed to-
wards the top of the hole.
 Continue the vent run through the firestops.

C. Vent Termination
For Horizontal Terminations - To attach and secure the
termination to the last section of horizontal vent:
 Rotate and interlock the ends as described at the begin-
ning of the Installing Vent Components section.
 The termination kit should pass through the wall firestops
from the exterior of the building.
 Adjust the termination cap to its final exterior position on
the building.
WARNING: THE TERMINATI N CAP MUST BE
P SITI NED S THAT THE ARR W IS
P INTING UP.
For roundcap termination kits:
 Use the exterior pipelock hole on the round flange of the
wall firestop to secure the vent pipe in place.
For trapezoidal cap termination kits:
 Using screws secure the cap to the exterior wall through
the flanges in the cap.

For Vertical Terminations - To locate the vent and install
the vent sections:
 Locate and mark the vent centerpoint on the underside
of the roof and drive a nail through the centerpoint.
 Make the outline of the roof hole around the centerpoint
nail.
 The size of the roof hole framing dimensions depend on the
pitch of the roof. There MUST BE a 1-inch (25.4mm) clear-
ance from the vertical vent pipe to combustible materials.
 Mark the roof hole accordingly.
 Cover the opening of the installed vent pipes.
 Cut and frame the roof hole.
 Use framing lumber the same size as the roof rafters
and install the frame securely. Flashing anchored to the
frame must withstand heavy winds.
 Continue to install concentric vent sections up through
the roof hole (for inside vent installations) or up past the
roof line until you reach the appropriate distance above
the roof (for outside terminations).

To seal the roof hole and to divert rain and snow from the
vent system:
 Attach a flashing to the roof using nails and use a non-
hardening mastic around the edges of the flashing base
where it meets the roof.
 Attach a storm collar over the flashing joint to form a
water-tight seal. Place non-hardening mastic around the
joint between the storm collar and the vertical pipe.
 Slide the termination cap over the end of the vent pipe
and rotate the pipe clockwise 1/4 turn.
