LP Gas System - cont'd.
Orifi ce
The orifi ce controls the fl ow of propane gas to the burner.
When replacing the orifi ce always use the size orifi ce specifi ed.
Using the wrong size or a damaged orifi ce will alter the amount
of propane fl owing to the burner.
!
Do not separate cap style LP15 orifice from its
adapter. Separating the assemblies breaks the seal
and causes an LP gas leak.
Burner
The burner, see Fig. 22, provides primary air access and
acts as the fuel mixing chamber to support ignition and the
combustion of propane gas. Primary combustion air fl ows into
the burner through three circular openings. Any obstruction
blocking any of the three openings will have an effect on the
fuel/air mixture. Insuffi cient combustion air will cause carbon
deposits to clog the burner slots. Carbon clogged burner
slots along with heavy dirt deposits in the burner are the main
cause of no cooling or poor cooling performance when the
refrigerator is operating in LP gas mode.
Burner Tube
The burner tube is 1/4 inch OD aluminum tubing with an anti-
vibration loop and a double fl are at each end. See Fig. 23.
