Installation Manual 11
Connect the LP Gas Components
This refrigerator operates on LP gas at a pressure of 2.7kPa LP gas. The refrigerator LP gas usage is:
N304M models
1.00 MJ/h
N404M and N504M models
1.40 MJ/h
Connect the LP gas supply system:
Be very careful when working on or near the LP gas system.
- Do not smoke or use an open flame near the LP gas system.
- Do not use an open flame to examine for leaks.
- Do not connect the refrigerator to the LP gas tank without a pressure regulator between them.
- To avoid a LP gas leak, always use two wrenches to tighten or loosen the LP gas supply line
connections.
- Leaking LP gas can ignite or explode and result in dangerous personal injury or death.
Connect the LP gas supply line to the refrigerator:
- Make sure all tubing and fittings obey all local, state, and national codes about size and type.
- Use of 3/8 inch copper tubing as the LP gas supply line and a 3/8 inch SAE (UNF 5/8-18) female flare fitting as the connection to
the refrigerator.
- Put the LP gas supply line up through the floor of the enclosure.
- Make sure the hole through the floor is large enough to allow clearance for the LP gas supply line.
- Put a weather resistant seal (grommet, sealant, etc.) around the LP gas supply line where it goes through the floor to prevent
vibration and abrasion.
- To prevent vibration and abrasion, make sure that the LP gas supply line is not against anything in the enclosure.
- Attach the LP gas supply line to the 3/8 inch male flare fitting of the refrigerator.
Examine the LP gas supply system for leaks:
Do not allow the leak detecting solution to touch the electrical components. Many liquids are electrically
conductive and can cause a shock hazard, electrical shorts, and in some cases, fire.
Use a leak detecting solution to examine the LP gas supply line and all LP gas connections for leaks.
If you use compressed air for the test:
- The pressure at the 3/8 inch male flare fitting of the refrigerator must not be more than 3.5 kPa.
- If the air pressure is more than 3.5 kPa, remove the LP gas supply line from the 3/8 inch male flare fitting of the refrigerator before
the test.
- If the air pressure is equal to or less than 3.5 kPa, turn the gas control to the off ( ) position before the test.
