WARNING: Extremely Hot!
Heat and flammability
• Some parts of the fireplace are extremely hot, par-
ticularly the glass windows. Use the barrier screens
provided or a gate to reduce the risk of severe burns.
• The glass windows can exceed 500°F (260°C) at full
capacity.
• Always keep the appliance clear and free from com-
bustible materials, gasoline, and other flammable
vapors and liquids.
• Be aware of hot wall surfaces! The walls directly above
the fireplace can get very hot when the fireplace
heats. Although safe, it may reach temperatures in ex-
cess of 200ºF (93°C) depending on choice of optional
accessories. Do not touch!
• Be aware of hot hearth/floor surfaces! Any projections
directly around the fireplace can get very hot when
the fireplace heats. Although safe, they may reach
temperatures in excess of 200ºF (93°C)depending on
elevation of hearth. Be careful of touching these! Tem-
perature of projection surfaces will be reduced when
barrier screens are installed.
• Some materials or items, although safe, may discolor,
shrink, warp, crack, peel, and so on because of the
heat produced by the fireplace. Avoid placing candles,
paintings, photos and other combustible objects
sensitive to heat or furniture within 36 inches (0.9m)

Specifications
Approval & Codes
This appliance is certified to ANSI Z21.88/CSA 2.33
American National Standard / CSA Standard for Vented
Gas Fireplace Heaters for use in Canada and USA, and
to CGA 2.17-91 High Altitude Standard in Canada. This
appliance is for direct vent installations.
This appliance complies with CSA P.4.1-15 Testing
method for measuring annual fireplace efficiencies.
The installation must conform to local codes or, in
the absence of local codes, with the National Fuel
Gas Code, ANSI Z223.1/NFPA 54 or the Natural Gas
and Propane Installation Code CAN/CGA-B149.1. Only
qualified licensed or trained personnel should install
this appliance.
This appliance must be electrically grounded in
accordance with local codes, or, in the absence of local
codes, with the National Electrical Code, ANSI/NFPA 70
or the Canadian Electrical Code, CSA C22.1.
Ratings
*High Altitude Installations
Input ratings are shown in BTU per hour and are
certified without deration for elevations up to 4,500
feet (1,370 m) above sea level.
For elevations above 4,500 feet (1,370 m) in USA,
installations must be in accordance with the current
ANSI Z223.1 and/or local codes having jurisdiction.
Heating value of gas in some areas is reduced to
compensate for elevation—consult your local gas
utility to confirm.
For installations at elevations above 4,500 feet
(1,370 m) in Canada, please consult provincial and/or
local authorities having jurisdiction.
Supply Gas
Heater engine 1500KN uses
natural gas.
Heater engine 1500KP uses
propane gas.
The supply pressure must be
between the limits shown in the Ratings section.
The supply connection is 3/8” NPT male and located on
the left hand side of the firebox. A shut-offvalve (not
supplied) is required on the supply line to isolate the
unit during service. See Gas Supply Installation section
for details.
Conversion Kits
The 1500K are supplied as natural gas or propane
gas and are field convertible between fuels. See
instructions packaged with the conversion kits for
further information.
Electrical
The 1500K are designed to run on battery power and
do not require an electrical power source to operate
as a heater. However, they require electrical power
to operate optional 1595CFKV2 Circulating Fan Kit,
1270RBK Remote Blower Kit, or GV60WIFI WiFi Kit.
HeatShift™System
The 1500K are designed to allow the installation of the
optional HeatShift System, a convection system that
redistributes the warm air flow away from the fireplace
opening to a more desirable location using natural
convection, without use of a fan.
The warm air flow may be relocated to a position higher
up the wall, out the sidewalls, or even to another room.
The result is much cooler wall temperatures above the
fireplace opening for locating televisions, artwork, etc.
Please note that the framing and mantel clearances
are affected by the installation of the HeatShift
System. Refer to “Appendix D—HeatShift™System™” on
page 73 for more information.
Outdoor Conversion Kit
The 1500K models are supplied standard for indoor
applications and may be adapted for installation in
specific “outdoor” applications protected from weather
as defined in the GV60CKO outdoor conversion kit
manual.

Minimum Cement Board Dimensions
Non-Combustible Cement Board
The L1 Linear fireplace requires a 1/2” (13mm) thick
non-combustible cement board to be used as a wall
surface immediately surrounding the unit’s opening—
see diagram for minimum coverage.
Extending the cement board well beyond the minimum
shown will help avoid cracking due to differential
expansion of materials.
Pre-drill cement board with oversized holes and do
not over-tighten screws to avoid cracking due to heat
expansion.
Standard gypsum wall board may be used beyond the
perimeter of the cement board.

may choose to leave it finished clean with no tile, etc.
Be aware that a trim is always required. Finish should
not cover the trims.
1575 and 1550 Trims
Only the 1575 and 1550 style trims will accept tile, etc.
tucked behind them (up to 5/8” thick for the 1575 and
up to 1 inch thick for the 1550).
1530 Trim
1530 trim must be installed BEFORE cement board.
Cement board and finishes are applied to the perimeter
of the trim frame. Cement board and finished CANNOT
be tucked under this trim.

Avoiding Cracking Wall Finishes
We recommend installing the optional LDK HeatShift
Duct Kit to reduce the wall temperatures and
minimize the possibility of cracking wall finishes.
If a clean finish with no tile, etc. is desired, joints in the
cement board and the transition to gypsum board
will require special attention if future cracking is to be
controlled. Be aware that temperatures on the non-
combustible wall surface above the appliance can
exceed 200°F (93°C).
Below are some tips on how to best avoid any cracking:
• Allow materials to dry thoroughly before finishing the
wall. Cement board has the ability to absorb up to 30
percent of its weight in water and may shrink as much
as 1/8” over a 48” length when drying from a satu-
rated condition. Running the fireplace for an extended
period before final finishing will help drive out mois-
ture.
Installation Planning Wall Finish
• 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 lage 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
inside corners. Provide a joint that intersects the inside
corner to avoid cracking.

Venting Overview
10” (254 mm)
10” (254 mm)
Align the vent center
to the center of the
frame
Top or Rear Outlet
This unit is supplied with a top vent outlet which can
be field-converted to a rear vent outlet. See Appliance
Preparation section for more information.
Vent Material
This unit is approved for installation using
4 x 6-5/8 inches co-axial direct vent pipe and
accessories as listed in the Approved Venting Components
section on pages 61–62 of this manual. Follow the
installation instructions supplied with the individual
venting accessories.
This unit may also be converted to co-linear (2 x 3 in)
venting for use in solid-fuel burning fireplaces and
chimneys using adapters and accessories—see list
in the Approved Venting Components section on pages
61–62 of this manual.
Vent Sealing
Seal all outer coaxial pipe and elbow joints, including
sectioned elbow outer 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 outer 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¼ inch
overlap.
Wall Thickness
The appliance vent is suitable for penetrating a
combustible wall assembly up to 8 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.
Framing Vent in Combustible Walls & Ceilings
When penetrating through combustible walls and
ceilings, frame a minimum of 10 in x 10 in opening and
ensure that the insulation is kept clear of the vent pipe
using either a wall thimble or an attic insulation shield.
Follow the installation instructions supplied with the
individual venting components.
Important Installer Notice – Weather
Sealing & Vapor Barriers
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 water 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 penetrat-
ing 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.
Tape all
OUTER 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.
