Examine The Gas Supply System For Leaks - Norcold N300 Installation And Owner's Manual

- Do not use an open flame to examine for leaks.
- Do not connect the refrigerator to the gas tank without a
pressure regulator between them.
- To avoid an propane gas leak, always use two
wrenches to tighten or loosen the gas supply line
connections.
- Leaking propane gas can ignite or explode and result
in dangerous personal injury or death.
Connect the gas supply line to the refrigerator:
- Make sure all tubing and fittings obey all local, state, and
national codes about size and type.
- Make sure that all flexible metal connectors obey the current
CAN1-6.10 Standard.
- Use 3/8" diameter copper tubing as the gas supply line and
use a 3/8" SAE (UNF5/8 -18) female flare fitting as the
connection to the refrigerator.
- Put the gas supply line up through the floor of the enclosure
and in a manner to prevent vibration and abrasion.
- Make sure the hole through the floor is large enough to
allow clearance for the gas supply line.
- Put a weather resistant seal (grommet, sealant, etc.)
around the gas supply line where it goes through the floor
to prevent vibration and abrasion.
- Attach the gas supply line to the bulkhead fiting [2] of the
refrigerator (See Art01254).

Examine the gas supply system for leaks:

WARNING: 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 solution of liquid detergent and water to examine the gas
supply line and all gas connections for leaks.
If you use compressed air for the test:
- The pressure at the manual shut off valve of the refrigerator
must not be more than 1/2 psig (14 inches Water Column).
- If the air pressure is more than 1/2 psig (14 inches Water
Column), remove the gas supply line from the bulkhead
fitting of the refrigerator before the test.
- If the air pressure is equal to or less than 1/2 psig (14
inches Water Column), close the manual shutoff valve of
the refrigerator before the test.
