1.0 INSTALLATION INSTRUCTIONS
In planning the installation for the heater it is neces-
sary to determine where the unit is to be installed, the
type of flue system to be used (straight out, corner, or
elevated), and whether optional accessories (wall
switchorremote control)aredesired. Gas supply pip-
ing should also be planned. Refer to the appliance
data plate on the base pan of the heater for all gas
pressuresand inputrate information.
The heater can be mounted on any of the following
surface:
1. A flat surface (minimun 6mm base).
2. Four(4) corner supports.
(Example: Four(4) concrete masonry blocks).These
supports must be positioned so they contact all four
(4) perimeter edges on the bottom of the unit.
Heater framing can be built before or after the heater is
set in place. Framing should be positioned to accom-
modate wall covering and heater facing material. The
heater framing should be constructed of 2" X 4" (51 x
102mm)lumber or heavier.The framingheaders may
rest on the heater standoffs. Refer to Figure 2 and
Figure3 for heaterand framingreference dimensions.
CAUTION: Measureheater dimensions, and verify
framingmethodsandwallcoveringdetails before fram-
ingconstruction begins.
1.1 INTRODUCTION
Thismodelisdesignedtooperatewithallcombustionair
being siphoned from the outside of the building and all
exhaust gases expelled to the outside of the building.
WARNING: THIS UNIT IS NOT FOR USE WITH
SOLID FUEL.
These units MUST usethe flue terminationdescribed
in the flueing section of the manual.
The control system for these models are a millivolt
type. It consists of a gas control valve/variable regu-
lator, a standingpilot/thermopile/thermocouple, apiezo
ignitor, andan ON/OFF switch.The controlsare located
behindthe lower grille. Access tothe controlsis gained
by rotating the grille up. See Figure 1.
Minimuminlet gas supply pressure forpurpose ofinput
adjustment is 4.5 inches w.c. (1.13kPa) for natural gas
and11inchesw.c.(2.75kPa)forpropane.Manifold(oulet)
pressures should be set at 3.0 inches w.c. (.75kPa) for
natural gas models and 9.6 inches w.c. (2.40kPa) for
propanemodels.
Framing should be constructed
of 2 X 4 lumber or heavier.
The framing headers may rest on
the fireplace stand-offs.

NOTES: 1. All distances are measured vertically or horizontally along the wall to a point
in line with the nearest part of the terminal.
2. Prohibited area below electricity meter or fuse box extends to ground level.
3. See clause 5.13.6.6 for restrictions on a flue terminal under a roofed area.
4. See Appendix J, Figure J1(a) and J2(a) for clearances required from a flue
terminal to a LP Gas cylinder. A flue terminal is considered to be a source of ignition.

1.2 FLUE SYSTEM APPROVALS
Thesemodels have fluestarting collarson both thetop
and the back of the unit. Depending upon the installa-
tion, decide which ONE set of starting collars will be
usedto attach the flue system.Thestartingcollarsealing
cap must remain on the starting collar NOT used.
Thesemodels use SL-D-seriesdirect fluecomponents
when using the TOP flue collars and D-series direct
flue components when using the REAR flue collars.
WARNING:YOU MUST NOT MIX D-SERIESAND
SL D-SERIES COMPONENTS IN ANY FLUE
SYSTEM CONFIGURATION.
Approved flue system components are labeled for
identification. NO OTHER FLUEING SYSTEMS OR
COMPONENTS MAY BE USED. Detailed installation
instructions are included with each flue termination kit
andshouldbeusedinconjunctionwiththis manual .Figure
5belowshowsfluesystemcomponentsandterminations.
Identifying Flue Components
The flue systems installed on this gas fireplace 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 onthenext few pages.
Ifa 90°elbow isfirst attachedto theunit, themaximum
horizontal run is 2 feet (610mm).

1. Attach the First Flue Component to the
Starting Collars
To attach the first flue component to the starting
collars of the fireplace:
• Apply a 3/8 inch (10mm) bead of stove cement
around the inner pipe heater starting collar.
• Make sure that the heater rope gasket sup-
plied with the heater seals between the first
flue component and the outer heater wrap.
• Lock the flue components into place by sliding
theconcentricpipesectionswithfour(4) equally
spaced interior beads into the heater collar or
previouslyinstalledcomponentendwithfour(4)
equally spaced indented sections.
• When the internal beads of each outer pipe line
up, rotate the pipe section clockwise about one-
quarter (1/4) turn. The flue pipe is now locked
together.

around the preceding component’s vertical axis. If
an elbow does not end up in a locked position with
the preceding component, attach with a minimum
of two (2) sheet metal screws.
3. Install Support Brackets
For Horizontal Runs - The flue system must be
supported every five (5) feet (1.5M) of horizontal
run by a horizontal pipe support.
To install support brackets for horizontal runs:
• Place the pipe supports around the flue pipe.
• Nail the pipe supports to the framing members.

For Vertical Runs
The flue system must be supported every eight
(8)feet(2.4M)above the heater flue outlet bywall
brackets.
To install support brackets for vertical runs:
• Attach wall brackets to the flue pipe and se-
cure the wall bracket to the framing members
with nails or screws.
Use wall brackets to support vertical runs every
8 feet (2.4M) above the heater flue outlet.
Figure 18 Installing Support Brackets
4. Install Firestops
For Horizontal Runs - Firestops are REQUIRED
on both sides of a combustible wall through which
the flue passes.
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)
holethroughthe wall for D-series ora 10-inch by
10-inch (254mm x 254mm) hole for SL D-series
pipe. The center of the hole is one (1) inch
(25mm) above the center of the horizontal
flue pipe.
• Position the firestops on both sides of the hole
previouslycutandsecurethefirestopswithnails
or screws.
• The heat shields of the firestops MUST BE
placed towards the top of the hole.
• Continue the flue run through the firestops.

Figure 20 Heat Shield, Interior and Exterior
Firestops
For Vertical Runs - One ceiling firestop is
REQUIRED at the hole in each ceiling through
which the flue passes.
Toinstallfirestopsforverticalrunsthatpassthrough
ceilings:
• Position a plumb bob directly over the center of
the vertical flue component.
• Mark the ceiling to establish the centerpoint of
theflue.
