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.

turer. No substitute material may be used.
• Do not strike or slam the glass front.
• Do not use abrasive cleaners on the glass front as-
sembly. 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 appliance with the glass
front removed, cracked, or broken.
Replacement of the glass should be done
by a licensed or qualified service person.
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

IMPORTANT! A free space of 3/4 inch (19 mm) is required in front of the
barrier screen to allow the window to move and relieve during a hard
start. The use of the optional fret sets this space with the fret bracket
installed.
However, when the fret is not used and the bottom cover is used
instead, this space immediately in front of the barrier screen must be
added to the minimum depth as a safety precaution. It is very
important to ensure that the area immediately in front of the barrier
screen is kept clear at all times even when not using a fret.

Minimum
vertical height 8 ft (measured to bottom of termination)
Maximum
horizontal run 4 ft (measured center to center of pipe)
Maximum
offset angle 45° (sweeping bend to allow for obstructions)
Venting Notes
Where possible, avoid splicing flex pipes.
Co-linear installations ONLY. If splices are required,
use an approved connector and seal joints with RTV
high temp sealant.
Four feet horizontal is permissible to allow for routing
around masonry projections. Do not bend flex pipe
over a 45 degrees radius.
• Co-linear venting may be converted to solid 4” x
6-5/8” co-axial venting at the top of the existing solid-
fuel burning chimney as necessary where the exist-
ing chimney has deteriorated and been removed.
The conversion must be done using approved com-
ponents (see page 40) and proper vent clearances
to combustibles must be maintained.
• Flex lilners may only be installed into solid-fule burn-
ing fireplaces and chimney systems (no combustible
constructions).
• The appliance must not be connected to a chimney
flue serving a separate solid-fuel burning appliance.
Note
This appliance may also be vented using the optional
720SWK—Co-Linear Sidewall Kit as shown on page 10.

Minimum Cavity Dimensions
The diagram shows minimum dimensions required to install the RF24.
Cavities having a combination of all the minimum dimensions shown
possible, may prove to be difficult installations.
IMPORTANT! A free space of 3/4 inch (19 mm) is required in front of the
barrier screen to allow the window to move and relieve during a hard
start. The use of the optional fret sets this space with the fret bracket
installed.
However, when the fret is not used and the bottom cover is used
instead, this space immediately in front of the barrier screen must be
added to the minimum depth as a safety precaution. It is very
important to ensure that the area immediately in front of the barrier
screen is kept clear at all times even when not using a fret.

Co-Axial with RA24CA Typical Vent Installation
Typical Vent Installation
See Approved Venting Components on page 40 of this
manual.
Vent Location
The vent terminal must be located throught the roof.
This direct vent appliance is designed to operate when
an undisturbed airflow hits the outside vent terminal
from any direction.
Check local codes for allowable vertical vent
termination.
Venting Table
Maximum
vertical height 40 ft (measured to bottom of termination)
Minimum
vertical height 8 ft (measured to bottom of termination
Maximum
horizontal run 4 ft (measured center to center of pipe
Maximum
offset angle 45° (sweeping bend to allow for obstructions)
Venting Notes
Where possible, avoid splicing flex pipes.
Four feet horizontal is permissible to allow for routing
around masonry projections. Do not bend flex pipe
over a 45 degrees radius.
• Flex liners may only be installed into solid-fule burn-
ing fireplaces and chimney systems (no combustible
constructions).
• The appliance must not be connected to a chimney
flue serving a separate solid-fuel burning appliance.

periodically for corrosion and damage and
replaced when necessary. If the installation does
not allow for future inspection or replacement of
the flexible aluminum liners, then stainless steel
vent liners are recommended.

The venting system for this appliance is considered to
be a Special Venting System. The rule in the Installation
Code CAN/CGA-B149 requiring a minimum vent height
of 2 feet above any portion of a building within 10 feet
does not, therefore, apply.

Preparation Existing Fireplace Preparation
Existing Fireplace Preparation
A few points must be considered before inserting the
RF24 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 RF24 engine. Cutting away any
sheet metal parts of the existing fireplace to
accommodate the installation of the RF24 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 RF24 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 RF24 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 RF24 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 RF24 insert.
Combustible Mantels
Combustible mantel clearances must conform to those
required for the original solid-fuel fireplace into which
the RF24 is being installed.
Attach Warning Conversion Plate to Existing
Fireplace
(plate supplied loose with RF24 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.
