Safety and Warning Information
READ and UNDERSTAND all instructions carefully
before starting the installation. FAILURE TO FOLLOW
these installation instructions may result in possible fi re
hazard and will void the warranty.
Prior to the fi rst fi ring of the fi replace, READ the Owner’s
Information section of this manual.
DO NOT USE this appliance if any part has been
under water. Immediately, CALL a qualifi ed service
technician to inspect the unit and to replace any part of
the control system and any gas control that has been
under water.
THIS UNIT IS NOT FOR USE WITH SOLID FUEL.
Installation and repair should be PERFORMED by a
qualifi ed service person. The appliance and venting
system should be INSPECTED before initial use and at
least annually by a professional service person. More
frequent cleaning may be required due to excessive
lint from carpeting, bedding, etc. It is IMPERATIVE that
the unit’s control compartment, burner, and circulating
air passageways BE KEPT CLEAN to provide for
adequate combustion and ventilation air.
Always KEEP the appliance clear and free from
combustible materials, gasoline, and other fl ammable
vapors and liquids.
NEVER OBSTRUCT the fl ow of combustion and
ventilation air. Keep the front of the appliance CLEAR
of all obstacles and materials for servicing and proper
operation.
Due to the high temperature, the appliance should be
LOCATED out of traffi c areas and away from furniture
and draperies. Clothing or fl ammable material SHOULD
NOT BE PLACED on or near the appliance.
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.
This gas fi replace and vent assembly MUST be
vented directly to the outside and MUST NEVER be
attached to a chimney serving a separate solid fuel
burning appliance. Each gas appliance MUST USE
a separate vent system. Common vent systems are
PROHIBITED.
INSPECT the external vent cap on a regular basis to
make sure that no debris, plants, trees, shrubs are
interfering with the air fl ow.
The glass door assembly MUST be in place and sealed
before the unit can be placed into safe operation.
DO NOT OPERATE this appliance with the glass door
removed, cracked, or broken. Replacement of the glass
door should be performed by a licensed or qualifi ed
service person. DO NOT strike or slam the glass door.
The glass door assembly SHALL ONLY be replaced
as a complete unit, as supplied by the fi replace
manufacturer. NO SUBSTITUTE material may be
used.
DO NOT USE abrasive cleaners on the glass door
assembly. DO NOT ATTEMPT to clean the glass door
when it is hot.
TURN OFF the gas before servicing this appliance.
It is recommended that a qualifi ed service technician
perform an appliance check-up at the beginning of
each heating season.
Any safety screen or guard removed for servicing MUST
BE REPLACED before operating this appliance.
DO NOT place furniture or any other combustible
household objects within 36” of the fi replace front.
BE CAREFUL not to put any decorating objects
sensitive to heat too close to the fi replace as it gets
very hot when operating.
DO NOT use this heater as a temporary source of heat
during construction.
This unit MUST be used with a vent system as described
in this installation manual. NO OTHER vent system or
components MAY BE USED.
NOTE: When operating your new fi replace for the fi rst time, some vapors may be released due to the burning
of curing compounds used in the manufacture of the appliance. They may cause a slight odor and could cause
the fl ames to be the full height of the fi rebox, or even slightly higher, for the fi rst few hours of operation. It is also
possible that these vapors could set off any smoke detection alarms in the immediate vicinity. These vapors are
quite normal on new appliances. We recommend opening a window to vent the room. After a few hours use, the
vapors will have disappeared and the fl ames will be at their normal height.

The RF24 is certifi ed for use with approved 3” diameter fl exible venting installed into an approved existing solid
fuel burning masonry or factory built chimney system. The venting system must terminate vertically at the roof
using an approved termination cap. Both inlet and exhaust liners must be run continuously from appliance to roof
termination. Where possible, avoid joints in fl ex pipe. If joints are required, use only connectors approved by the
manufacturer of the fl ex pipe. Field fabricated joints are not allowed.
Any generic 3” diameter fl exible venting approved for venting gas appliances is acceptable.

10” dia.
The RF24 is approved for Vertical Co-Linear Termination Only. Two 3” diameter
liners are required from top to bottom. The vent liners must be connected to the proper
collars (intake and exhaust) or the unit will not operate properly. The method of fl ashing
will depend on whether the liners are installed into a rectangular masonry or round
10”
factory-built solid-fuel burning chimney. It is important to seal the gap at the top
11
of the chimney in either case to avoid convective air loss up the chimney. The
integrity of the air-cooled function of factory-built chimney systems must be maintained
when installing terminations. Termination of the chimney may need to be completed
7-5/8” dia.

after the RF24 fi rebox is installed and the slack vent liner pulled up—see Section
Installing Firebox.
Existing Square Chimneys
559CLT Co-Linear Terminal and 559SFK Square Flashing Kit are
required. Cut fl ashing kit to size. Allow extra around perimeter for drip
edge to be formed on site. Seal fl ashing to top of chimney using sealant
(not supplied). Fasten terminal to fl ashing using sheet metal screws as
shown.
