Once the gas has been allowed to pass<br />
through the safety valve, it flows to the gas jet<br />
and burner. These have been specifically<br />
designed to eliminate most of the normal maintenance<br />
required due to the corrosive contaminants<br />
in the gas, as well as soot and rust<br />
which fall from the flue pipe. The jet has an<br />
orifice made of an industrial ruby which has<br />
been laser-beam drilled. Each model of<br />
<strong>Dometic</strong> refrigerator uses a different size orifice<br />
in order to maintain the required amount of<br />
heat at the siphon pump. To clean the jet and<br />
burner, soak them in an alcohol base solvent<br />
and allow to air dry. DO NOT use a pin or<br />
needle. This will distort or shatter the orifice.<br />

If you determine that disassembly is required,<br />
be aware there are two model designs for<br />
manual refrigerators. The design pictured here<br />
will be discussed first.<br />

Shut off the main gas supply, then disconnect<br />
at the back of the refrigerator. Remove the<br />
cover over the thermostat and burner protection<br />
cover at the right,<br />

Now disconnect the 12 volts at the terminal<br />
block and unplug the 120 volt cord. Remove<br />
the two mounting screws on the left and pull<br />
the metal locking arm out from under the<br />
burner housing.<br />
