NOTE: After changing an LP tank, or after a long shut off period, the gas line is likely to be filled with air. You may have to repeat the lighting procedure several times to purge the air out of the gas lines. - Page 6 OPERATION REFRIGERATORS WITH TOP MOUNT CONTROLS REFRIGERATORS WITH PIEZO IGNITORS: RM2452 AND RM2453 LEGEND: A Energy Selector Knob B Thermostat Knob C Flame Failure Safety ---_-__-----m-------------v- Valve Push Button D Piezo lgnitor E Flame Indicator REFRIGERATORS WITH AUTOMATIC IGNITION: RM2552 AND RM2553...
- Page 7 GAS OPERATION REFRIGERATORS WITH PIEZO IGNITOR (RM2452 & RM2453) To start the refrigerator, turn knob “A” to the “GAS” position. Turn the thermostat knob “B” one-quarter (1/4) of a turn from the “OFF” position. Push button “C”, push button “D” for the piezo ignitor several times to light the burner. This can be observed on the flame indicator “E”, on the refrigerator.
- Page 8 AC VOLTAGE REQUIREMENTS The proper operating range is 100 to 132 volts. Check the AC volts at the receptacle where the refrigerator is attached. If voltage drops below 100 volts, cooling efficiency will decrease with voltage decrease. AC COMPONENTS HEATING ELEMENT To check a heating element, remove the heater leads from the terminal block and measure for proper resistance across the two leads.
- Page 9 B. The RM251 O/RM261 O/RM2810 selector switch should be checked for continuity in the following manner. Remove all wires from the assembly. continuity should exist between terminals 1 and IA and2 and 2A. should For the DC mode, For the gas mode, you have continuity between 3 and 3A.
- Page 10 IGNITER A. MODEL RM2310,2410,2452,2453 When the button is pushed, a spring loaded striker creates a spark. If there is no resistance when pressing the button, the piezo igniter is defective. B. MODEL RM2510,2610,2810,2552,2553 Check that the switch is in the gas mode and is completing the circuit. Next, verify proper voltage at the positive (+) and ground (-) terminals of the igniter.
- Page 11 HIGH VOLTAGE CABLE Be sure switch and igniter are good before checking the high voltage cable and the switch is in the gas mode. Disconnect DC power at the terminal block. Disconnect high voltage cable from electrode. Reconnect DC power to the terminal block.

HEATING ELEMENT (3-WAY MODELS ONLY) Check the heating element with ohms resistance using a properly calibrated ohm meter. You should obtain the following readings, plus or minus 10%: 1.15 OHMS RM2310 RM2410 1.15 OHMS .82 OHMS RM2510 RM2610 .67 OHMS RM2810 .67 OHMS RM2453... - Page 13 FILTER A filter is located in the inlet fitting to the thermostat. The filter can become saturated and cause a restriction to gas flow. If you suspect a restriction, first verify the thermostat and bypass screw are good. THERMOSTAT LP GAS MODE The thermostat is calibrated by the manufacturer so that at mid-range the cabinet temperature should be approximately 40 degrees Fahrenheit.
