WARNING
SAFETY WARNING! The Horizon is a very effective radiant heater.
HOT WALL SURFACES! The wall directly above the fireplace may be constructed of combustible
materials and, although safe, may become very hot when the fireplace is operating. Do not
touch! Finish the wall directly above the fireplace using materials and methods suitable for
elevated temperatures.
HEARTH/FLOOR SURFACES! The hearth/floor in front of the fireplace can get very hot. Locating
the unit raised above the hearth/floor and using the screen front will help reduce hearth
temperatures. Note that some materials, although safe can degrade due to heat—take this
into consideration when choosing materials.
Note: This appliance may be installed in outdoor, weather protected
environments as defined in the GV60CKO Outdoor Conversion Kit
instruction manual.

12
Planning Framing
• A non-combustible hearth is not necessary in front of
this appliance.
• Note that the appliance is installed at the framing
stage and secured to framing using support angles.
See page 24, 26. Wall finish is then installed
afterwards over the support angles and up to the
perimeter of the unit.
NOTE
When the appliance is installed directly on
carpeting, tile or other combustible material
other than wood flooring, the appliance shall be
installed on a metal or wood panel extending the

Non-Combustible Materials Specifications
Non-combustible materials are those which will not
ignite and burn. Such materials are those consisting
entirely of steel, iron, brick, tile, concrete, slate, glass
or plasters, or any combination thereof.
Materials that are reported as passing ASTM E 136,
Standard Test Method for Behavior of Materials in a
Vertical Tube Furnace at 750 °C shall be considered
non-combustible materials.
Combustible Materials Specifications
Materials made of or surfaced with wood, compressed
paper, plant fibers, plastics, or other material that
can ignite and burn, whether flame proofed or not,
or plastered or unplastered shall be considered
combustible materials.
Cracking Wall Finishes
If a clean finish with no tile, etc. is desired, joints in the
gypsum board will require special attention if future
cracking is to be controlled.
Shrinkage and differential movement of the framing
and wall board can transmit cracking through to tiles,
etc.
Be aware that temperatures on the wall surface above
the appliance can exceed 185°F. Although safe, this is
too hot for many many materials and finishes. Choose
materials that will withstand these temperatures.
Cracks
Provide joints
either here or
here
Below are some tips on how to best avoid any cracking:
• Allow materials to dry thoroughly before finishing the
wall. Some materials, such as cement board has the
ability to absorb up to 30 percent of its weight in wa-
ter and may shrink as much as 1/8” over a 48” length
when drying from a saturated condition. Running the
fireplace for an extended period before final finishing
will help drive out moisture. Moisture is the leading
cause of material shrinkage!
• Always pre-drill screw holes through cement board
and use screws with self-milling head.
• Always use mesh tape over joints.
• Always stagger joints in wall board.
• Behind joints, double up studs or use studs “on the
flat” to add extra support to the joint. Adhesive on
the backside of wall board behind any joints can help
control differential movement.
• Use multiple, thinner coats of joint compound and al-
low to dry thoroughly between coats.
• Ensure framing materials are dry.
• After finishing the wall, introduce heat gradually to
slowly dry any excess moisture rather than drying too
fast.
• Avoid notching cement board or tiles around corners
of window opening and instead provide a joint that
intersects the corner.
• Avoid using large, one-piece slab of material with a
cut-out in the middle as a surround for the fireplace.
Expansion above the opening will cause cracking at in-
side corners. Provide a joint that intersects the inside
corner to avoid cracking.

Venting
Top or Rear Facing Outlet
This appliance is supplied with a top vent outlet which
can be field-converted to a rear facing vent outlet. See
page 23 for more information.
Vent Material
This appliance is approved for installation using
4 x 6-5/8-inch co-axial direct vent pipe and accessories
as listed in Approved Venting Components pages
41–42. Follow the installation instructions supplied
with the individual venting accessories.
This appliance may also be converted to co-linear
venting with two 3-inch pipes for use in solid-fuel
burning fireplaces and chimneys using approved
adapers and accessories. See Co-Linear Conversion
pages 21–22 and Approved Venting Components
pages 41–42.
Vent Sealing
Seal all outer co-axial pipe and elbow joints, including
sectioned elbow joints, using high quality, high
temperature 2-inch wide self-adhesive aluminum foil
tape (Nashua-322-2 brand or similar). Wrap the tape
completely around all joints and press firmly to seal.
A high-temperature black silicone sealant may be used
in the outer joints as a substitute to foil tape.
Ensure all the pipe joints have a minimum of 1-1/4 inch
overlap.
Wall Thickness
The appliance vent is suitable for penetrating a
combustible wall assembly up to 14 inches in thickness.
A non-combustible wall can be of any thickness up to
the maximum horizontal run of vent pipe allowed for
the particular installation.
Vent Penetration Through Walls & Ceilings
Combustible
When penetrating through combustible walls and
ceilings, frame a minimum of 10 inches x 10 inches
opening and ensure that the insulation is kept clear
of the vent pipe using either a wall thinble or an attic
insulation shiedl. Follow the installation instructions
supplied with the individual venting components.
Non-combustible
If the wall is totally non-combustible (e.g. masonry
block or concrete), mark for a 7-inch circular hole.
In both cases, the center of the hole should line up with
the center line of the horizontal vent.
Overview
Tape all joints
(including all
elbow joints)

All horizontal pipe runs must be graded 1/4 inch
per foot upwards in the direction of the exhaust
flow. The final pipe length, when terminating
through the wall may be graded downwards slightly
to prevent water migration.

Important Installer Notice—Weather Sealing & Vapor Barrier
It is the installer’s responsibility to ensure that vent installations through exterior walls are caulked and
weatherproofed in such a manner as to:
• Prevent rain from entering the wall from the weather side by adequately caulking the outer vent plate to the
exterior wall surface.
• Prevent moisture inside the home from penetrating into the wall structure by ensuring the inside wall plate is
adequately sealed to the inside vapor barrier.
• Prevent rain water and moisture from entering the walls by sealing the joints between the outer vent tube and
the inner and outer wall plates.
We recommend the use of a high quality polyurethane sealant.

How to Read the Venting Charts
The charts below apply to co-axial roof or wall termina-
tion in installations with vertical rise. See page 17 for
installations with no vertical rise.
1. The total length of the vent pipe cannot exceed
40 feet.
2. The minimum vertical height with roof termination is
10 feet.
3. Any combination of rise and run can be used as long
as they are within the allowable limits shown on the
chart below.
4. A maximum of 4 x 90 degrees elbows—or equivalent
(2 x 45 degrees = 90 degrees)—can be used.
Venting
Venting Charts
Co-axial
5. Each 90 degrees elbow installed on the horizon-
tal plane is equivalent to a 3 feet horizontal pipe;
therefore, 3 feet must be subtracted from allowable
horizontal run. (45 degrees elbow is equivalent to
18inches horizontal pipe.)
6. All horizontal pipe runs must be graded 1/4 inch per
foot upwards in the direction of the exhaust flow.
The final pipe length, when terminating through the
wall may be graded downwards slightly to prevent
water migration.
7. Maximum co-linear venting is 40 feet.
8. A restrictor is required for all installations—see
Restrictors page 25 for more information.

Co-Axial Vertical Installations
• Check the roof pitch to determine which roof flash-
ing will be needed. See Approved Venting Components
pages 41–42 for allowable components.
• The distance from the roof to the lowest terminal
discharge opening (“H” in figure) depends on the roof
pitch and must be in accordance with the manufac-
turer’s instructions supplied with the termination unit.
Note: The venting system for these appliances is consid-
ered to be Special Venting System.The rule in the CAN/
CGA-B149 Installation Code requiring a minimum vent
height of 2 feet above any portion of a building within
10 feet does not, therefore, apply.
• The minimum clearances to combustible materials
all round the vent pipes must be in accordance with
the dimensions shown in Venting Configurations—With
Vertical Rise page 18 of this manual.
• Drop a plumb from the ceiling to the center of the ap-
pliance vent opening. Mark the position on the ceiling.
Drill a small hole at the marked position.
• Determine the position where the vent will pass
through the roof. If directly above the position where
it penetrates the ceiling, drop a plumb from the roof
to the small hole in the ceiling and mark the roof at
this spot.
If rafters or other obstructions will prevent a vertical
exit or if clear attic space is desired, the roof outlet
can be offset using 45 degrees elbows.
Drill a small hole at the marked position.
• A ceiling firestop must be installed at the second floor
and higher floors.
A ceiling support should be used below the flat ceiling.
To install the firestop and support, cut and frame a
10inches (254 mm) square hole centered on the small
hole previously drilled.
• Fit vent accessory elbows a pipe lentghs as required
up through ceiling support boxes and firestops.
If installation includes offset, support the offsetting
pipes every 3 feet (1 m) with wall straps as shown.
• Cut a hole in the roof centered on the small hole. The
hole must allow for the minimum clearrences to com-
bustible materials. See Venting section in this manual.
• Fit pipe lengths through the roof. Fit roof flashing
securing it with roofing nails.
• Fit storm collar and termination cap.
