Installation Manual 9
Ignition - propane gas operation (N400 models):
1. Open the valve at the propane gas storage tank.
2. Turn the thermostat [1] to the 5 position.
3. Turn the selector switch [2] to the propane gas position ( ).
4. Push and hold in the safety valve [4] and push in the igniter
[3] several times in rapid succession, for about five seconds:
WARNING:
Do not hold in the safety valve for more than
30 seconds. If there is no flame in this time, wait at least
five minutes before you try ignition again. If you continue
to hold in the safety valve, gas will collect in the burner
area. This could cause a fire or explosion and result in
dangerous personal injury or death.
- When a flame is present and the flame meter [5] moves
into the green area, release the safety valve.
- If the flame meter does not move into the green area, do
this step again.
5. Turn the thermostat to the temperature setting that you wish.
Ignition Start Up
- 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 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.
- 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 fiting [2] of the
refrigerator (See Art00975).
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 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.
