The controls of the EZ Freeze Propane Refrigerator are located on the front of the unit at the bottom. All are hidden by the door or a removable panel. The controls include the Thermostat Control (shown as "Temp" within the below image) which controls the temperature of both the refrigerator and freezer compartment. It adjusts the amount of refrigerant running through the system by controlling the high and low flame of the burner. The refrigerant of the absorption system is an ammonia and water solution that flows via gravity from the top of the freezer to the refrigerator section below and absorbing all the hot air. The higher the temperature control is set the more the flame will stay on high and produce more refrigerant, therefore making the interior colder.
The Gas Safety Valve on the EZ Freeze Propane Refrigerator (shown as "Gas" within the below image) is the Gas Safety Shut-off Valve. This valve is magnetically controlled by an electro-magnet that is feed millivolts via the thermocouple. The thermocouple is heated by the flame and produces the small amount of electricity to power the magnet. If the flame is extinguished and the thermocouple does not sense heat, then the electro-magnet will release and shut-off the gas supply. This prevents any unburned gas from escaping into the room.
The Piezo Igniter of the EZ Freeze Propane Refrigerator (shown as "Spark" within the below image) is a non-electric powered spark generator. Very similar to what outdoor gas BBQ's use. By pushing this button, the Piezo Igniter will produce a spark to light the flame.
Lighting a gas refrigerator
After the set-up of the unit is complete, use the following procedure to light the burner. First time lighting may take longer than usual due to the air that may be in the gas lines.
Turn on the gas valve at the rear of the gas refrigerator
To start the gas refrigerator, turn the thermostat knob "Temp" (Thermostat) to the #2 setting
Push and hold "Gas" (Gas Safety Valve) button, and then...
Press the "Spark " (Piezo Igniter) button continuously 5 to 10 times to light burner. Confirm the flame is lit by viewing through the flame "Viewer". It should be possible to hear a slight turbulent noise from the flame. If the burner is lit, continue holding the "Gas " button for 5-15 seconds. Release the "Gas" button and confirm the burner is still lit. If the burner does not light, repeat steps 1 through 4.
We recommend to take a good look at the flame upon initial start up and memorize the size and color for future reference. It is good practice to visually check the flame for this size and color upon every start up.Hand Lighting....
If for some reason the unit will not light with the piezo ignition or the igniter is failing to spark, it is possible to hand light the burner. This usually requires two people. Simply use the above procedure and replace "Spark " Button with a person at the burner with a lighter.
