Installation Manual 9
Connect the Propane Gas Components
- Make sure the power cord(s) does not touch the burner
cover, the flue pipe, or any hot component that could
damage the insulation of the power cord.
Connect the 12 volts DC supply:
As the distance from the vehicle battery to the refrigerator
increases, the correct AWG wire size and fuse size also
increases. If the wire size is too small for the distance, a
voltage drop occurs.
1. Determine the min. wire size and the max. fuse size to use:
WARNING: If you use an incorrect wire size and/or fuse
size, electrical fire can result.
- Use a minimum of 18 AWG wire and a maximum 6 Amp
fuse.
- If the wire size is larger than the min. size, use the correct
fuse per RVIA A119.2 standard or local codes.
2. Install a fuse in DC power supply wires between the battery
and the refrigerator:
- Put fuse as close to the battery as possible.
3. Connect the DC power supply wires (See Art00966):
- Attach a 1/4 inch Quick Connect terminal to each DC power
supply wire.
NOTE: Do not use the chassis of the refrigerator or the
vehicle frame as one of the conductors. Attach the
DC power supply wires only to the battery and the
power board [1] of the refrigerator.
- Push the positive DC power wire [2] onto the power board
terminal that is marked 12VDC.
- Push the DC ground wire [3] onto the power board terminal
that is marked 12V GND1.
- Make sure each DC power supply wire is on the correct
polarity terminal.
Connect the propane gas supply system:
WARNING:
Be very careful when working on or 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 propane 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 that 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.
- Make sure that the materials used for the gas supply line
obey both the current ANSI A 119.2 (NFPA 1192) and CSA
Z240 Standards on Recreational Vehicles. Norcold
recommends the use of 3/8 inch copper tubing as the gas
supply line and requires 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 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.
- Make sure that the propane gas supply line does not
interfere with removal of the burner box cover or block the
door opening of the burner box cover.
- 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 combination gas valve of
the refrigerator.
This refrigerator operates on propane gas at a pressure of 11
inches Water Column Propane.
The controls operate on 12 volts DC (10.5 volts min. - 15.4 volts
max.). Operation out of these limits can damage the refrigerator
electrical circuit parts and will void the warranty
