    Orifice Size/Altitude Adjustment For altitudes above 2,000 feet, the orifice should be de-rated by 4% for every 1,000 feet to maintain the proper ratio of gas to air. Improper orifice sizing may result in damage and unsafe conditions. Changing the orifice should only be done by a qualified service technician. Contact your Lennox Hearth Products dealer for proper orifice sizes (see Page 21 and 24 for more information). The Firestar™ Insert • Must conform with all local, state, and national installation codes. In the absence of local codes, the installation must conform with National Fuel Gas Code ANSI Z223.1 - latest edition, also known as NFPA 54. Refer to the National Fuel Gas Code and local zoning and code authorities for details on installation requirements. • Must conform with the Manufactured Home Construc- tion and Safety Standard, Title 24 CFR, Part 3280, or when such a standard is not applicable, the Standard for Manufactured Home Installations, ANSI A225.1 - latest edition for manufactured (mobile) home installations.

    Installation nsert enting Refer to Figure 6 which shows a typical installation of this ap- pliance into an existing solid-fuel fireplace. WARNING: This appliance is equipped with a safety control sys- tem designed to protect against improper venting of combustion products. Operation of this heater when not connected to a prop- erly installed and maintained venting system or tampering with the blocked vent shut-off system can result in carbon monoxide (CO) poisoning and possible death. Insert must be vented to the outside in accordance with the current edition of the National Fuel Gas Code ANSI- also known as NFPA 54 . The insert must not be connected to a chimney flue serving a separate solid fuel burning appliance. This gas insert requires a 4” diameter B-vent or listed flex alu- minum or stainless chimney liner extending the entire length of the chimney to ensure proper operation. The vent should terminate with a chimney cap or rain cap. Chimney should be sealed around cap to prevent air and rain from entering chimney.

    2” f ower ront iller anel The FireStar™ insert comes with a 2” panel to fill the space be- tween the insert bottom and the hearth extension. If the hearth elevations necessitate, the insert may be installed directly on the hearth without the leveling bolts or filler panel. To install the panel, insert the four tabs on the top of the panel into the corresponding slots in the insert bottom. Open the insert side doors, remove the two socket head screws from the hardware bag and install them (using a 5/32” hex wrench) through the insert bottom into the filler panel. A tall adjustable filler panel is also available. nstallation After leveling, position the insert in the fireplace, holding it about six inches out from its final location. Caution: Specific Hearth Requirements apply (see Clearances and Specifications). The Firestar gas insert must be connected to the gas line in accordance with local codes and / or the National Fuel Gas Code, Z.1-latest edition, also known as NFPA 54.

Marks left on these surfaces may become etched into the finish if not removed prior to burning the unit. - Check all gas fittings for leaks. - Remove all combustible materials from the area in front of the insert and ensure the vented areas of the insert face are unobstructed. - Check to ensure all clearances to combustibles are met- see page 7. - Make sure the glass door is in place and properly sealed before burning the appliance - Ventilate the house to clear initial paint curing odors, see...

    TO TURN OFF GAS TO APPLIANCE (Refer to controls shown in Figure 16) 1. Turn off the "ON/OFF" rocker switch and/or thermostat (if installed) to its lowest setting. 2. Turn off electric power to the appliance if service is to be performed. 3. Push in gas control knob slightly and turn clockwise to "OFF." Do not force. This appliance needs fresh air for safe operation and must be installed so there are provisions for adequate combustion and ventilation air. WARNING: Improper installation, adjustment, alteration, service, or maintenance can cause injury or property dam- age.

    aint uring This insert has been painted with Stovebright high tem- perature metallic stove paint. It leaves the factory dry to the touch, but finishes curing as the insert is used. Fire the insert four successive times for ten minutes each time with a five minute cool down between each firing. Ventilate the house during these first firings as the paint gives off car- bon dioxide and unpleasant odors. It is recommended that persons sensitive to an imbalance in the indoor air quality avoid the insert during the curing process. uiet peration GAS NOISE: The sound of gas flowing through the insert may be detectable while the unit is in operation. This is a normal operating sound, however if it is objectionable, it can be reduced by turning down the flame. Turning down the flame will reduce heat output. BLOWER NOISE: As the insert heats up, the blower will come on to move hot air through the heat exchanger and into the room. Adjust the fan speed with the fan control knob to the sound level and air flow desired. lower Your Firestar™ gas insert comes equipped with a 150 CFM blower with a variable speed control and an automatic temperature activated On / Off snap switch.

  • Page 16: Illivolt Ontrol Ystem

    Do not splice any millivolt wires. Refer to Table 3 to determine the proper gage of wire for the thermostat or wall switch connections. This table refers to the total length of the wire (out to the switch and back). The thermostat must be a millivolt type. A 24-volt furnace thermostat will not work. Never hook up household current, 120 Volts, to the millivolt system. It is not recommended to hook up any more than two switches to the insert (for example a rocker switch and a wall thermostat). Additional switches may affect the system resistance and increase the chance of the burner not ignit- ing. Follow the instructions included with the thermostat or remote control for wiring. The thermostat, remote control, and rocker switch will turn the burner on and off independently. Be sure to set the rocker switch to the “OFF” position when using the thermostat or remote control and set the thermostat or remote control to the lowest temperature when you wish to use the rocker switch only, otherwise one may override the other. If a re- mote thermostat is to be used with the insert, do not place the receiver under the firebox. Thermostat Wire Wire Size 1 Gage 14 Gage 16 Gage 18 Gage 0 Gage Table ...

    & C onversion assette nstallation Converting your FireStar™ gas insert between natural gas and LP can be accomplished by either changing the Quick Change Cassette (valve and pilot assembly) or installing a conversion kit (regulator, burner orifice and pilot orifice). Only a qualified service technician should perform the conversion, as it requires discon- necting the gas supply line and other procedures that should only be performed by a qualified technician. Cassette Removal 1. Be sure the gas supply is off and fan power cord is discon- nected before beginning the conversion. Disconnect the gas supply from the insert being careful not to apply pressure to the valve in the process. 2. Remove the log set and brick panels, (see “Brick Panel & Log Installation) 3. Remove the burner by lifting the left end and pulling the burner gently through the block plate and past the pilot assembly.
