Connect The Propane Gas Components; Connect The Propane Gas Supply System; Connect The Gas Supply Line To The Refrigerator; Examine The Gas Supply System For Leaks - Thetford N304.3 Installation And Owner's Manual

2. Connect the D.C. power supply wires:
- Attach a fully insulated 6.35 mm Quick Connect terminal to
each DC power supply wire.
- Push the positive (+) DC power wire onto the white DC wire.
- Push the negative (-) DC power wire onto the yellow DC
heater wire.
- Make sure each DC power supply wire is on the correct
polarity terminal.

Connect the Propane Gas Components

This refrigerator operates on propane gas at a pressure of
2.7kPa propane. The refrigerator gas usage is:
N304 models
N404 and N504 models

Connect the propane gas supply system:

!
WARNING:
near the propane gas system.
- Do not smoke or use an open flame near the propane
gas system.
- Do not use an open flame to examine for leaks.
- Do not connect the refrigerator to the propane gas tank
without a pressure regulator between them.
- To avoid a 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.
- Use of 3/8 inch copper tubing as the gas supply line and
a 3/8 inch SAE (UNF 5/8-18) male flare fitting as the
connection to the refrigerator.
- Put the propane 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 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.
1.25 MJ/h
1.4 MJ/h
Be very careful when working on or
- To prevent vibration and abrasion, make sure that the gas
supply line is not against anything in the enclosure.
- Attach the gas supply line to the bulkhead fitting [91] of the
refrigerator (See Art01890).

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 leak detecting solution to examine the gas supply line and
all propane 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 3.5 kPa.
- If the air pressure is more than 3.5 kPa, 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 3.5 kPa, close the
manual shutoff valve of the refrigerator before the test.
