6.5 Connecting the gas
FIRE OR EXPLOSION HAZARD. Failure to obey the following warnings could result in property
damage, serious injury, or death:
• Install gas connections in compliance with the applicable supplemental directives listed in this manual. Refer
to"1.3 Supplemental directives" on page 3.
• Never use an open flame to check for gas leaks. Use a commercial leak detection solution to check all
connections, as specified in these instructions.
• Should the gas supply fail to shut off or if overheating occurs, shut off the gas valve to the refrigerator before
shutting off the electrical supply.
• Do not put sealing compound on flair fittings.
• Never use a wire or pin to clear obstructions from burner jet (damage will occur).
• Do not attempt to adjust burner jet.

Read before proceeding:
• Connection to the gas supply line is accomplished at the manual gas valve. The manual gas valve is furnished
with a 3/8" SAE (UNF 5/8" -18) male flare connection.
• The gas supply system must incorporate a pressure regulator to maintain a supply pressure of not more than
11" water column.
• When testing the gas supply system at test pressures:
– greater than 1/2 psi, the refrigerator and its individual shutoff valve must be disconnected from the gas
supply piping system.
– 1/2 psi, or less, the refrigerator must be isolated from the gas supply piping system by closing the
individual manual shutoff valve.
• If local codes allow for the use of a flexible gas appliance connector, do not use a connector that has
previously serviced another gas appliance.
• If detailed instructions on the installation and connection to the gas supply are required, contact the nearest
dealer or distributor.
➤ Always use two wrenches to hold the valve and flair nut when loosening and tightening gas connections.
➤ Route all connections to avoid contact with the boiler casing, burner cover, or any other refrigerator
components.
➤ Perform an air pressure test on the piping system.
➤ Examine all completed connections for leaks using a commercially available soap solution made for the
detection of leaks.
