Connect The Propane Gas Components; Connect The Gas Supply System - Norcold N305X Installation Manual

- If the distance is 0 - 20 feet, use a minimum of 12 AWG wire and a maximum 20 amp fuse.
- If the distance is more than 20 feet, use a minimum 10 AWG wire and a maximum 30 amp fuse.
- If the wire size is larger than the min. size, use the correct fuse per RVIA A119.2 standard or local codes.
The wire connections must be clean, tight and free of corrosion. If any of these items are not correct:
- A voltage drop to the refrigerator will occur.
- The voltage drop will reduce the cooling performance of the refrigerator.
The terminals for connecting the DC power supply are marked positive (+) and negative (-) on the terminal block of the refrigerator.
Make sure that:
- Each DC power supply wire is attached to the correct polarity terminal.
- The chassis or the vehicle frame is not used as one of the conductors.
- The DC power supply wires including the fuses are routed directly
from the battery to the refrigerator.
2. Connect the D.C. power supply wires:
- Attach a 1/4 inch female Quick Connect terminal to each DC power
supply wire.
- Push the positive (+) DC power wire onto the terminal block [219] tab
with the
12V (+) mark. (See Art02535)
- Push the negative (-) DC power wire onto the terminal block tab with
the
12V (-) mark. (see Art02535)
- 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 11 inches Water Column Propane.
Connect the propane gas supply system:
! Be very careful when working on or near the propane gas system.
WARNING
- 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 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.
- Make sure that the materials used for the gas supply line obey both the current 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) female flare fitting as the connection to the refrigerator.
