Connect The Propane Gas Supply System; Examine The Gas Supply System For Leaks; Ignition And Start Up - Norcold N109XXX Installation Manual

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.

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 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 of the compressed air at the manual shut off
valve of the refrigerator must not be more than 1/2 psig (14
inches Water Column).
- If the pressure of the compressed air is more than 1/2 psig
(14 inches Water Column), remove the gas supply line from
the combination gas valve of the refrigerator before the test.
- If the pressure of the compressed air is equal to or less than
1/2 psig (14 inches Water Column), close the manual shut
off valve of the refrigerator before the test.

Ignition and Start Up

Before ignition or start up of the refrigerator:
- Make sure the air flow in the lower intake vent, through the
refrigerator coils and condenser, and out the upper exhaust
vent is not blocked or decreased.
- Make sure there are no combustible materials in or around
the refrigerator.
Ignition and start up:
(See Art01018)
NOTE: If the gas does not ignite in 30 seconds, the gas safety
valve of the refrigerator automatically closes and the
controls either select a different energy source or "no"
"FL" appears in the center display. This means that the
gas did not ignite.
If the gas does not ignite after several attempts, refer to the "Fault
Codes" section of this manual.
Automatic Mode Operation:
1. Push the ON/OFF button [30] to start the refrigerator.
