LP GAS SYSTEM
Leak testing can be accomplished using an electronic
leak detector or a commercial grade leak test solution.
The use of home made soap and water leak test
solution should be avoided if possible. When applying
leak test solutions, apply the solution over the entire
joint using a small brush or spray applicator.

Due to low system operating pressure, it may take a
few minutes for bubbles to appear if the connection is
leaking. Hidden joints should be examined thoroughly
using an inspection mirror.

Figure 8. LP Gas System Components.
The refrigerator LP gas system, shown in Figure 8, is
for propane gas use only. The system working
pressure is 10.5 and 11.5 in. water column. Propane
gas pressures below 10.5 in. w.c. or above 11.5 in.
w.c. will affect heat output which in turn will affect
cooling efficiency. Propane gas flow control is
monitored by electronically by the controls flame
sensing circuit. If the flame sensing circuit does not
detect a burner flame within 30 seconds after initiating
ignition, power to the gas valve is turned off and gas
mode is locked out.

WARNING:
When working on or near the LP gas system:
n
Do not smoke or light fires! Extinguish all open
flames!

n
Do not use an open flame to leak test any of the
LP gas system components. LP gas is highly
flammable and explosive.
