WARNING: Extremely Hot!
Heat and ammability
• 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 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)
around the fireplace.
• Due to it high temperatures, the appliance should be
located out of traffic areas and away from furniture
and draperies.
• Clothing or flammable material should not be placed
on or near the appliance.
Barrier Screen and Safety
• A barrier designed to reduce the risk of burns from
the hot viewing glass is provided with this appliance
and shall be installed for the protection of children
and other at-risk individuals.
• Children and adults should be alerted to the hazards
of high surface temperature and should stay away to
avoid burns or clothing ignition.
• Young children should be carefully supervised when
they are in the same room as the appliance. Toddlers,
young children, and others may be susceptible to
accidental contact burns. A physical barrier is recom-
mended if there are at-risk individuals in the house. To
restrict access to a fireplace or stove, install an adjust-
able safety gate to keep toddlers, young children, and
other at-risk individuals out of the room and away
from hot surfaces.
• Any safety screen, guard, or barrier removed for ser-
vicing an appliance must be replaced prior to operat-
ing the appliance.

• This appliance is designed and approved as a supple-
mental heater and provides the potential for most
energy conservation when used while attended. The
use of an alternate primary heat source is advisable.
• This unit is not for use with solid fuel.
• Do not use this heater as a temporary source of heat
during construction.
Installation and Servicing
• Installation and repair should be done by a qualified
service person. The appliance should be inspected
before use and at least annually by a professional
service person. More frequent cleaning might be
required due to excessive lint from carpeting, bedding
material, et cetera. It is imperative that control com-
partments, burners, and circulating air passageways
of the appliance be kept clean.

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 2500KN uses natural gas.
Heater engine 2500KP 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 2500K 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 2500K 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 the lights and optional GV60WIFI WiFi Kit.
HeatShift™System (Required)
The 2500K requires the installation of the 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.
Refer to “Appendix D—HeatShift™System™” on page
72 for more information.
Outdoor Conversion Kit
The 2500K 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.

Installation Planning Wall Finish
Non-Combustible Finishing Over
Non-Combustible Board
Additional material such as tile, etc.,
may be applied over top of the non-
combustible board or you 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.
2575 Trim
Only the 2575 style trim will accept tile,
etc. tucked behind it (up to 5/8” thick for
the 2575).
2530 Trim
2530 trim must be installed BEFORE non-
combustible board. Non-combustible
board and finishes are applied to the
perimeter of the trim frame. Non-
combustible board and finish CANNOT
be tucked under this trim.
Do Not Drill/Screw Areas
The face of the replace must not be
drilled or screwed into as shown below.
These areas house electrical and/or
control elements of the replace that
could be damaged and present risk of
injury.
Clean Installation Kit (2530) does not adjust
forward. Non-combustible board finishes
up to perimeter of the trim. Must be
installed before finish.

Cracks
Provide joints
either here or

Avoiding Cracking Wall Finishes
If a clean finish with no tile, etc. is desired, joints in the
non-combustible 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. Non-combustible 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 saturated condition. Running the fireplace for an
extended period before final finishing will help drive
out moisture.
• Always pre-drill screw holes through non-combustible
board and use screws with self-milling head.
• Always use mesh tape over joints.
• Always stagger joints in wall board.
Installation Planning Wall Finish
• 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 non-combustible 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.

10” (254 mm)
Align the vent center
to the center of the
frame
Top or Rear Outlet
This unit is supplied with a vent outlet which can
be installed either as top facing or rear racing. 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 (3” x 4”)
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 joints, using high quality, high tem-
perature 2 inch wide self-adhesive aluminum foil tape
(Nashua-322-2 brand or similar). Wrap the tape com-
pletely 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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.

How to Read the Venting Chart
The chart below applies to co-axial roof or wall
termination.
1. The total length of the vent pipe cannot exceed
40 feet.
2. The minimum vertical height with roof termination
is 6 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. Excludes the 45 degrees take-offelbow
shipped with the appliance.
5. Each 90 degrees elbow installed on the horizontal
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. A restrictor adjustment is required for most
installations having a vertical rise—see next
section.
Note: The restrictor is shipped installed at the
exhaust exit of the firebox.
