1Approvals and
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
After determining which set of starting collars will be used
(top or rear) follow venting instructions accordingly.
N TE: The SL-350TRS and SL-350TRS LP are built with the
air shutter set for top vented configurations. If venting out the
rear of the unit adjust the air shutter per the following table.
Venting ut the Rear Vent (SL-350TRS) (See Figure 17)
Remove the installed rear seal cap from the rear starting collars
by cutting the strap at each end. Remove the insulation inside
the 5 collar. Follow the vent configuration tables accordingly.
Remove the 5 diameter heat shield from the 5 diameter collar
by sliding it out.
WARNING: THE T P HEAT SHIELD (INSIDE
THE FIREB X) MUST REMAIN ATTACHED IF
THE VENT SYSTEM IS ATTACHED T THE
REAR STARTING C LLARS. SEE FIGURE 17.
Venting ut the Top Vent (SL-350TRS)
Remove the top vent collar seal cap by cutting the strap at
each end. Remove the insulation inside B TH the 4
diameter and 6 5/8 diameter collars. (See Figure 17).
Remove the 4 diameter heat shield from the 4 diameter
collar by sliding it out.
You have to take the glass off for positioning the logs when
the unit is finally installed in place and finished around it. Attach
vent system to the top starting collars.

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 fireplace inner vent starting collar.
 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 outer pipe line up ro-
tate the pipe section clockwise about one-quarter (1/4)
turn. The vent pipe is now locked together.

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.
 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.

4. Install Firestops
For Horizontal Runs - Firestops are REQUIRED on both
sides of a combustible wall through which the vent passes.
N TE: Model DVK-01TRD or SLK-01TRD does not need
an exterior firestop 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 (305 mm X 305 mm) hole through
the wall for D-series or a 10-inch by 10-inch (254 mm X 254
mm) hole for SL-D-series pipe.
The distance from the floor to the center of the framing hole
should match dimensions D or E in Figure 4 (page 12). The
center of the framing hole is one (1) inch (25.4mm) above
the center of the horizontal vent pipe.
2. Continue Adding Vent Components
 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.
 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 19. Adding Venting Components
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.

For Vertical Runs - One ceiling firestop is REQUIRED at
the hole in each ceiling through which the vent passes.
To install firestops for vertical runs that pass through ceilings:
 Position a plumb bob directly over the center of the verti-
cal vent component.
 Mark the ceiling to establish the centerpoint of the vent.
 Drill a hole or drive a nail through this centerpoint.
 Check the floor above for any obstructions such as wir-
ing or plumbing runs.
 Reposition the fireplace and vent system if necessary
to accommodate the ceiling joists and/or obstructions.
 Cut a 10-inch X 10-inch (254mm X 254mm) hole through
the ceiling using the centerpoint previously marked.
 Frame the hole with framing lumber the same size as the
ceiling joists.
Figure 24. Ceiling Firestop (Ceiling Side)
If the area above the ceiling is N T an attic position and
secure the ceiling firestop on the ceiling side of the previously
cut and framed hole.
Figure 23. 10" x 10" Hole & New Framing Members
If the area above the ceiling IS an attic position and secure
the firestop on top of the previously framed hole.
NOTE: Kee insulation away from the vent i e at least
1 inch (25mm).
