WARNING: DO NOT BUILD A WOOD FIRE. DO NOT BURN  
WOOD OR OTHER MATERIAL IN THESE APPLIANCES.  
FOR USE ONLY WITH DECORATIVE TYPE UNVENTED ROOM  
HEATERS.  
CAREFULLY REVIEW THE INSTRUCTIONS SUPPLIED WITH  
THE DECORATIVE TYPE UNVENTED ROOM HEATER FOR  
THE MINIMUM FIREPLACE SIZE REQUIREMENT.  
WARNING:IFTHEINFORMATIONINTHISMANUAL

REQUIRED FOR THE INSTALLATIONS.  
FOR YOUR SAFETY: Do not store or use gasoline

This is an unvented gas-fired heater. It uses air  
(oxygen) from the room in which it is installed.  
Provisions for adequate combustion and ventila-  
tion air must be provided. Refer to Combustion  
and Ventilation Air Section, Page 3.  
FOR YOUR SAFETY: What to do if you smell gas:  
DO NOT light any appliance.  
DO NOT touch any electrical switches.  
DO NOT use any phone in your building.  
• Immediately call your gas supplier from a  
neighbors phone.  
Follow your gas suppliers instructions.  
• If your gas supplier cannot be reached, call the  
fire department.  
Due to high temperatures, the appliance should be located out  
of traffic and away from furniture or draperies.  
Do not place clothing or other materials on or near this  
appliance.  
IMPORTANT: READ AND UNDERSTAND THESE INSTRUCTIONS  
COMPLETELY BEFORE INSTALLING YOUR UNVENTED ROOM  
HEATER.

The installation must conform with local  
codes or, in the absence of local codes with the  
National Fuel Gas Code, ANSI Z223.1.  
Massachusetts:  
COMBUSTION AND VENTILATION AIR  
These fireplaces are approved for installation  
in the US state of Massachusetts if the follow-  
ing additional requirements are met-  
These heaters shall not be installed in a con-  
fined space. The heater may be located in  
unusually tight construction provided the  
space is unconfined, or if confined, is pro-  
vided with two permanent openings commu-  
nicating directly with an additional room(s)  
of sufficient volume so that the combined  
volume of all connected spaces meets the  
criteria for an unconfined space, (National  
Fuel Gas Code ANSI Z223.1 (latest edition),  
Section 5.3). Generally 50 ft 3 per 1,000 BTU  
input of all operating appliances in the space.  
The heater and its individual shut-off valve  
must be disconnected from the gas supply  
pipingsystemwhileperforminganytestsofthe  
gas supply piping system at pressures in ex-  
cess of 1/2 psig.  
• Installation and repair must be done by a  
plumber or gas fitter licensed in the Common-  
wealth of Massachusetts.  
The flexible gas line connector used shall not  
exceed 36 inches (92 centimeters) in length.  
The heater must be isolated from the gas  
supply piping system by closing its individual  
manualshut-offvalveduringanypressuretest-  
ing of the gas supply piping system at test  
pressures equal to or less than 1/2 psig.  
The individual manual shut-off must be a T-  
handle type valve.  
Vent-FreeappliancesmayNOTbeinstalledin  
bedrooms or bathrooms.  
The National Fuel Gas Code defines a con-  
fined space as a space whose volume is less  
than 50 ft 3 per 1,000 BTU/Hr (4.8 m3 per kw)  
of the aggregate input rating of all appliances  
installed in that space and an unconfined  
space as a space whose volume is not less  
than 50 ft 3 per 1,000 BTU/Hr (4.8 m3 per kw)  
of the aggregate input rating of all appliances  
installed in that space. Rooms communicat-  
ing directly with the space in which the appli-  
ances are installed, through openings not  
furnishedwithdoors,areconsideredapart of  
the unconfined space.  
Keep heater area clear and free from com-  
bustible materials, gasoline and other flam-  
mable vapors and liquids.  
• A working smoke detector must be installed  
in the area where vent-free appliances are  
installed.  
Do not use this heater if any part has been  
under water. Immediately call a qualified ser-  
vice technician to inspect the room heater and  
to replace any part of the control system and  
any gas control which has been under water.  
Seller of unvented propane or natural gas-  
fired supplemental room heaters shall pro-  
vide to each purchaser a copy of 527 CMR 30  
upon sale of the unit.

New York:  
These fireplaces are approved for installation  
in the US state of New York, but not in New  
York city.

When local codes require the damper to be  
fixed open, a damper stop must be installed to  
prevent full closure of the fireplace damper  
and provide a minimum 29 square inch flue  
opening at all times. Refer to accessories for  
damper clamp.  
Ensure the minimum clearances shown inFig-

taminants from passing through the pipe to  
the heater controls and burners (Figure 9 ).  
Failure to do so could prevent the heater from  
operating reliably.  
A qualified gas appliance installer must install  
this heater.

Figure 14  
Main Burner Characteristics The flames at  
the front burner holes will be blue becoming  
orange as they hit the bark-like texture of the  
base and front face of the log.  
If, after a period of use, the flames start to  
exhibit unusual shapes and behavior, or the  
burners fail to ignite smoothly, then the burner  
holes may require some cleaning. If this hap-  
pens, contact your nearest dealer to get the  
appliance serviced.  
OPERATION AND CARE OF YOUR  
APPLIANCE  
1. Appliance operation may be controlled  
through the ON/OFF unit rocker switch, located  
in the control compartment, or through a re-  
motely located optional wall switch or wall  
thermostat.

REPLACEMENT PARTS  
An incorrect pilot flame pattern is shown in  
Figure 13. This pilot flame will cause the  
thermocoupletocool. Whenthethermocouple  
cools, the log set will shut off. If pilot flame  
pattern is incorrect, or if log set shuts off,  
contact your service representative.  
An exploded view of the room heater with  
numbered parts and a parts list can be found  
on pages 16 and 17. All parts should be or-  
dered through your Lennox distributor or  
dealer.Partswillbeshippedatprevailingprices

the control knob clockwise and counterclock-  
wise respectively.  
When ordering repair parts, always give the  
following information:  
3. When lit for the first time, the appliance will  
emit a slight odor for an hour or two. This is  
due to the “burn-in” of the internal paints and  
lubricants used in the manufacturing process.  
For the first few hours, operate the appliance  
with doors and windows open to encourage  
the dissipation of odor.

Wall Thermostat Kit*  
OPTIONAL EQUIPMENT  
A wall thermostat kit is available for use with  
these appliances. The wall thermostat is de-  
signed to be wired directly to the appliance  
millivolt gas control circuit and provide auto-  
matic On/Off control of the appliance to main-  
tain a desired temperature within the room.  
All options are available in kit form, are easy to  
install and are packaged complete with all re-  
quired parts and instructions. Some of the  
option kits need to be fitted prior to completing  
the installation of the appliance. The following  
paragraphs detail the kit options available.  
Damper Clamp  
P/N 110701  
DCK  
The appliances covered in this manual are  
heater rated and produce a great deal of heat.  
Decorative brass trim pieces and hoods may  
tarnish because of their proximity to the heater  
opening and front face. Tarnishing of these  
pieces is normal, unavoidable and should be  
expected.  
Decorative Volcanic Stone  
The decorative volcanic stone, Model FDVS,  
can be used to enhance the look of your appli-  
ance. Spread the decorative volcanic stone  
evenly around the bottom of the firebox.  
Adjustable Canopy  
Remote Control Kits  
An attractive black canopy kit is available for  
use with these VF appliances. The canopy kit is  
designed to be fitted to the wall above the  
firebox opening. In addition to providing an  
aesthetically pleasing appearance, the canopy  
reduces heat effects to decorative mantles and  
finish materials located directly above the fire-  
place opening. The canopy kit includes the  
necessary attaching hardware.  
Models RCL and RCL-STAT add the conve-  
nience of remote control for your appliance.  
The kits include a wireless, hand held trans-  
mitter and a receiver. This special receiver  
permits either manual or remote control  
modes.Bothreceiverandtransmitteroperate  
on standard 9 volt batteries (not included).  
Refer to the RCL and RCL-STAT installation  
instructions for specific details.
