This manual contains very important information about the safe installation and operation of the fireplace. Read and
understand all instructions carefully before installing and operating the fireplace. Failure to follow these instructions
may result in possible fire hazard and will void the warranty.
Replacement manuals are available by contacting the Valor Customer Service at 1-800-468-2567, or by visiting
valorfireplaces.com.
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)
around the fireplace.
• Any safety screen, guard, or barrier removed for ser-
vicing an appliance must be replaced prior to operat-
ing the appliance.
• If the installation includes a horizontal surface above
the fireplace, do not place items on top of the fire-
place. This space is not a shelf.
• Due to its high
temperatures, the
appliance should be
located out of traffic
areas and away from
furniture and draper-
ies.
• 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.
• 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.
• Clothing or flammable material should not be placed
on or near the appliance.

Fireplace Safety
Glass windows
• The glass front assemblies must be in place and
sealed before the unit can be placed into safe
operation.
• The glass front assemblies must only be replaced as
complete units, as supplied by the fireplace manufac-
turer. No substitute material may be used.
• Do not use abrasive cleaners on the glass front as-
semblies. Do not attempt to clean the glass when
it is hot.
Venting
• This unit must be used with a vent system as de-
scribed in this manual. No other vent system or com-
ponents may be used.
• Never obstruct the flow of combustion and ventilation
air. Keep the front of the appliance clear of all obsta-
cles and materials for servicing and proper operation.
• This gas fireplace and vent assembly must be vented
directly to the outside and must never be attached to
a chimney serving a separate solid fuel burning ap-
pliance. Each gas appliance must use a separate vent
system. Common vent systems are prohibited.
WARNING
Do not operate this appliance with the
glass front removed, cracked, or broken.
Replacement of the glass front should
be performed by a licensed or qualified
service person. Do not strike or slam the
glass front.
Intended use
• 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 1600KN uses
natural gas.
Heater engine 1600KP 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 1600K 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 1600K 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 1270RBK Remote Blower Kit or
GV60WIFI WiFi Kit.
HeatShift™System
The 1600K 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 67 for more information.
Outdoor Conversion Kit
The 1600K 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.

Notes—ALL venting considerations
• Dimensions of venting are based on us-
ing Dura-Vent elbows. Elbow curve radius
dimensions will vary when using other
brands and in general are slightly bigger.
• Minimum 12 inches vertical pipe section
required right at unit. Refer to venting chart
on page 28 for allowable horizontal runs.
• 3 inches to combustibles required above
horizontal pipe. Slope pipe upwards 1/4
inch per foot. 1 inch clearance required
around sides and bottom of horizontal pipe
and around vertical pipe.
• When calculating effective pipe lengths
subtract approximately 1-1/2 inch per pipe
joint - for example, a 12 inches pipe sec-
tion will add approximately 10-1/2 inches
overall.
Venting Considerations—Vertical Takeoff
Venting Considerations—Horizontal Takeoff
WARNING
If installing with a horizontal
surface above the fireplace, do
not use this surface as a shelf.
Do not place objects above the
fireplace as this surface will be

Installation Planning Wall Finish
Material Specifications
Non-Combustible
Material 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 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.
Minimum Cement Board Dimensions
Non-Combustible Cement Board
The L1 See Thru 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.

Additional non-combustible material such as tile, etc.,
may be applied over top of the cement board or you
may choose to leave it finished clean with no tile, etc.
Be aware that a trim is always required on the front and
rear of the unit. 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 finish 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 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 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. Minimum 12 inch vertical pipe section required right
at unit.
2. The total length of the vent pipe cannot exceed
40 feet.
3. The minimum vertical height with roof termination
is 6 feet.
4. Any combination of rise and run can be used as long
as they are within the allowable limits shown on the
chart below.
5. A maximum of 4 x 90 degrees elbows—or equiva-
lent (2 x 45 degrees = 90 degrees)—can be used.
Excludes the 45 degrees take-offelbow shipped
with the appliance.
6. 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.)
7. 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.
8. A restrictor adjustment is required for most installa-
tions having a vertical rise—see next section.
Note: The restrictor is shipped installed at the ex-
haust exit of the firebox.
