Fireplace Safety
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, particu-
larly the glass window. Use the barrier screen provid-
ed 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 wall 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! Do
not put objects on the hearth or shelf. Temperature
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.
• Solid wood flooring in front of the fireplace (if allowed)
may shrink during the heating season due to heat.
• Due to high temperatures, the appliance should be
located out of traffic areas and away from furniture
and draperies.
• Clothing or other flammable material should not be
placed on or near the appliance.
Barrier Screen and Safety
• Children and adults should be alerted to the hazards
of high surface temperature and should stay away to
avoid burns or clothing ignition.
• A barrier designed to reduce the risk of burns from
the hot viewing glass is provided with this appliance
and must be installed for the protection of children
and other at-risk individuals.
• 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.

Installation Preparation
Unpack the Appliance
1. Unpack the appliance.
2. Unpack any loose items from around the appliance
and check against the Pack Content list provided in
the documentation package.
3. Remove the window and set aside in a safe place to
avoid damage—see next page.
4. Verify that you have all the components required for
the installation, including:
• liner panels
• fuel bed
• trim
• venting components and accessories
• fan and electrical components for its installation
(if used)
WARNING
Beware of sharp edges! Wear gloves!
Existing Fireplace Preparation
A few points must be considered before inserting
the 780 into an existing fireplace cavity. Generally, no
modifications are allowed to the existing fireplace that
will compromise the integrity of the existing fireplace.
Components that are bolted or screwed on such as
dampers or baffles may be removed to accommodate
the installation of the 780 engine.
Cutting away any sheet metal parts of the existing
fireplace to accommodate the installation of the 780
is prohibited.
Check with local authorities if in doubt.
Clean Fireplace and Chimney
Have the chimney swept and the fireplace cavity
including ash dumps and clean-outs cleaned before
installing the 780 heater and vent liners. Any creosote
or soot residue remaining in the fireplace cavity
chimney or clean-out may cause odors or stains once
the 780 insert is installed. Consult with chimney sweep
for information on how best to clean.
Existing Dampers
Factory-built, zero-clearance fireplaces will require
the damper to be removed in order to install the vent
liners. These dampers are usually bolted into place.
Dampers in masonry fireplaces must be fixed open and
may remain in place.
Ash Retaining Curbs
Some fireplaces (particularly factory-built) have a
raised curb at the front edge to retain ashes. Check the
dimensions carefully to ensure the 780 engine will fit
behind any raised curb (some curbs may be removed
separately from the refractory base).
Gas Line Routing
Plan the routing of the gas line before proceeding.
Utilize the existing hole for the gas line of the factory-
built fireplace.
If the fireplace has no access hole, carefully drill an
access hole of 1.5 inch (38 mm) or less through the
lower sides or bottom of the firebox. The access hole
must be plugged with non-combustible insulation after
the gas supply line has been installed.
See Dimensions section for detailed location of gas inlet.
Also, take into consideration whether or not a fan or
shut-offvalve will interfere when planning routing of
the gas line.
Existing Glass Doors and Wire Screens
Existing glass doors must be permanently removed
prior to installing the 780 insert.
Combustible Mantels
Combustible mantel clearances must conform to those
required for the original solid-fuel fireplace into which
the 780 is being installed.
Attach Warning Conversion Plate to Existing
Fireplace
(Label supplied loose with 780 heater)
Attach the “This fireplace has been converted...” label to
the existing fireplace using screws or other mechanical
means and store any removed parts in back of the
existing fireplace for future use.

WARNING
Optional electrical accessories ARE NOT
ALLOWED when adapting appliance for
outdoor use.
Window and Fan
Installation Preparation
Install Fan Kit (if used)
If the 795CFKV2 Circulating Fan Kit (blower) is to be
installed, we suggest that you do it now.
The fan cavity is accessible from the back of the firebox
to facilitate its installation. If the fan is retrofitted after
the installation of the appliance, the appliance will need
to be removed. Therefore, we recommend that, where
possible, the fan be installed before the appliance is
fitted into the cavity.
Refer to instructions provided with the 795CFKV2 to
install the fan.
6’ power

Remove Window
The window is held in place by a spring-loaded lever on
each side. To remove the window:
1. Locate the levers on each side of the window
towards the top. Using your finger, pull the lever
towards you and unhook it from the window frame
bracket.
2. Gently pull the top of the window outward.
3. Lift the window out of its bottom railing and set it
aside in a safe place to avoid damage.

16
Connect Venting
Installation
Connect Venting
IMPORTANT: This appliance’s venting system is room
sealed and therefore, does not require room air to be used
in the combustion process.
1. Rough-in two 3” diameter vent liners into the existing
chimney system from the roof. Be careful not to tear
or damage the liners in the process. It may be easier to
install both liners at the same time rather than one at
a time. Leave plenty of liners at the bottom to facilitate
the connection of the liners to the vent slider. It is best
to leave the top termination until later.
Designate and mark the top and bottom of one liner
as “EXHAUST” to avoid confusion later.
2. Release the two screws retaining the vent slider to the
front of the firebox. Remove the slider from the firebox
by sliding it towards the back of the firebox.
3. Fit the two liners ensuring that the exhaust liner is
connected to the identified “EXHAUST” vent collar.
Secure liners to collars with hose clamps (included)
and 2 tapping screws per liner.
4. Slide the firebox onto the vent slider in the cavity tak-
ing care not to damage the liners. Make sure that the
rear edge of the slider is hooked over the cleat on
the firebox. Secure the vent slider to the front of the
firebox with two screws removed earlier.
5. From the roof, pull
the liners and fit the
flashing.
6. Fit the terminal cap
ensuring that the
exhaust liner is
connected to the
exhaust vent collar.

Gas Supply
Installation
Connect Gas Supply
The gas supply inlet connection is a 1/2” NPT female.
Gas shut-offvalve supplied on the end of stainless steel
flexible connector. Flex connector is located on the left
hand rear corner of the appliance.
Use only new black iron or steel pipes, CSST, or copper
tubing if acceptable—check local codes. Note that
in USA, copper tubing must be internally tinned for
protection against sulfur compounds.
The burner module and gas train on this appliance may
be removed as a unit for servicing. The flex pipe supplied
with the unit provides a union for removal of the module.
Unions in gas lines should be of ground joint type.
The gas supply line must be sized and installed to
provide a supply of gas sufficient to meet the maximum
demand of the appliance without undue loss of pressure.
Sealant used must be resistant to the action of all gas
constituents including LP gas. Sealant should be applied
lightly to male threads to ensure excess sealant does not
enter gas lines.
Pressure test the supply line for leaks.
The appliance and its individual shut-offvalve must be
disconnected from the gas supply piping system during
any pressure testing of that system at test pressures in
excess of 1/2 psig (3.5 kPa).
The appliance must be isolated from the gas supply
piping system by closing its equipment shut-offvalve
during any pressure testing of the gas supply piping
system at test pressures equal to or less than 1/2 psi (3.5
kPa).
Failure to either disconnect or isolate the appliance
during pressure testing may result in regulator or valve
damages and void the warranty. Consult your dealer in
case of damages.

WARNING
NEVER USE AN OPEN FLAME to check
for leaks. Correct any leak detected
immediately.
Pressure Test Points
The minimum supply pressure is given in the section
Specifications of this manual—page 6.
All piping and connections must be tested for leaks
after installation or servicing. All leaks must be
corrected immediately.
When testing for leaks:
• Make sure that the appliance is turned off.
• Open the manual shut-offvalve.
• Test for leaks by applying a liquid detergent or soap
solution to all joints. Bubbles forming indicate a gas
leak.
The pressure test tapping locations are shown in the
figure below. An internal regulator within the valve
controls the burner manifold pressure.
The correct pressure range is shown in the table in
section Specifications of this manual on page 6. The
pressure check should be made with the burner alight
and at its highest setting. See Lighting Instructions
section for full operating details on page 38.
