Orifice Size/Altitude Adjustment For altitudes above 2,000 feet (In Canada 4,500 FT/1370 M),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. Chang- ing the orifice should only be done by a qualified service technician. Contact your Lennox Hearth Products dealer for proper orifice sizes. The Medina™ 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 (In Canada, the current CAN/CSA B149.1 installation code). Refer to the National Fuel Gas Code and local zoning and code authorities for details on installation requirements. • Must conform with the Manufactured Home Construction and Safety Standard, Title 24 CFR, Part 3280 (in Canada CAN/CSA Z240 MH), or when such a standard is not applicable, the Standard for Manufactured Home Instal- lations, ANSI A225.1 - latest edition for manufactured (mobile) home installations. -

The fireplace is not dependent on the fan or an outside electrical supply to operate. Millivolt Valve This insert is operated with a millivolt valve and therefore burns even during a power outage. Fuel This insert comes from the factory equipped to burn natural gas at a specified elevation. The insert can be converted to burn LP (liquid propane) by installing a conversion kit. Only Lennox Hearth Products conversion kits can be used to convert from NG to LP or LP to NG. Contact your Lennox Hearth Products dealer for details. -

learanCe ireplaCe nstallation This insert may be installed in a masonry or factory built/zero clearance (ZC) fireplace. When installing in a ZC fireplace, the ZC grate must be removed and the ZC damper must be removed or secured open. The ZC doors, screen, refrac- tory or masonry lining, baffles, and smoke shelf may be removed if necessary to install the gas insert. However, do not cut or alter the fireplace components. The removal of any parts to facilitate installation must not alter the integrity of the inner or outer shells of the fireplace cabinet. Any parts removed must be replaceable if the insert is taken out of the fireplace or the fireplace must be clearly marked with the metal label that states: "This fireplace has been altered and is no longer safe to operate." The insert is designed to fit into a ZC fireplace with a minimum firebox height of 17-1/4" (438mm). To facilitate this the hood will need to be removed and discarded (Note: The screws should be replaced in the insert body). Installation of the flue collar is removable (see Flue Collar Connection). If the factory-built fireplace has no gas access hole(s) pro- vided, an access hole of 1-1/2" (37.5 mm) or less may be drilled through the lower sides or bottom of the firebox in a proper workmanship like manner. This access hole must be plugged with a non-combustible insulation after the gas supply line has been installed. The installer must mechanically attach the marking supplied with the gas fireplace insert to the inside of the firebox of the fireplace into which the gas fireplace insert is installed. -

Page 12: Gas Line Installation
Gas Line Installation After leveling, position the insert in the fireplace - holding it about six inches out from its final location. Caution: Specific hearth requirements apply (see Clear- ances to Combustibles). The Medina™ gas insert must be connected to the gas line in accordance with local codes and/or the National Fuel Gas Code, ANSI Z223.1 (In Canada, the current CAN/CSA B149.1 installation code). The insert comes with an 8" nipple at- tached to the supply side of the gas valve. After connecting the gas line, all joints in the line and connections at the valve should be checked for leaks with a gas leak test solution before final positioning of the unit. ressure equirements A MAJOR CAUSE OF OPERATING PROBLEMS WITH GAS APPLIANCES IS IMPROPER GAS PRESSURE!

5. Locate the pilot by looking over the top of the left front log. A blue flame will be seen when the pilot is lit. 6. Turn the gas control knob counter-clockwise to the "PILOT" position. 7. Push the knob all the way in and hold in that position. Immediately light the pilot by pressing the igniter button several times until pilot is lit. Continue to hold the knob in for about 30 seconds after the pilot is lit. Realease knob and it will pop back out. Pilot should remain lit. If it goes out, repeat steps 4-8 holding knob in an additional 15 seconds after pilot is lit. If knob does not pop out when released, stop and immediately call your service technician or gas supplier. If the pilot will not stay lit after several tries, turn the gas control knob to "OFF" and call your service technician or your gas supplier. 8. After pilot is lit, turn gas control knob counter-clockwise to "ON." Knob can only be turned to "ON" if the knob has popped out. 9. To turn burner on, turn "ON/OFF" rocker switch to "ON" or set the thermostat to the desired temperature above room temperature. -
Page 15: Paint Curing
Paint Curing 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 an unpleasant odor. It is recommended that persons sensitive to an imbalance in the indoor air quality avoid the insert during the curing process. Quiet Operation As the Medina™ gas insert is burning, a number of normal operational sounds may be heard. The flow of gas through the gas valve and orifice may make a rushing or whistling noise. -
Page 16: Perating Ptions
A wall-mounted switch, a millivolt wall thermostat, or a remote control, can be used to supplement the rocker switch. The gas valve is powered by millivolts generated by the pilot assembly. This millivolt system is very sensitive to electrical resistance, therefore, make sure all connections are tight, clean, and free from corrosion. Do not splice any millivolt wires. Consult the table on this Page 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 mil- livolt 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 igniting. Follow the instructions included with the thermostat or remote control for wiring.
