GAS FLAME GOES OUT OR IS IRREGULAR
NOTE
: Various safety features will turn gas off automatically.
1.)
If there is inadequate or fluctuating water pressure supply to the machine.
2.)
If the unit overheats or rises on temperature to the red line on the temperature
gauge.
3.)
If internal gas pressure is too high.
4.)
If you have a weak pilot or a cracked flame sensor rod.
WAIT 30 seconds for automatic re-ignition. If re-ignition does not occur, or if
machine shuts repeatedly, check the following:
a. Reduce LP gas pressure to reduce temperature by turning knob on the
gas regulator counter-clockwise.
b. Check nozzle for restrictions and clean.
c. Check water supply for adequate flow, check for leaks at fitting and
incoming water pressure.
d. Remove pilot orifice and clean dirt out.
e. Inspect and/or replace flame sensor rod, if cracked.
f. Make sure the propane tank was not overfilled.

Check for max. setting on the temperature gauge. The knob may be adjusted
downward. Keep red line @ 340˚.
2.)
Adjust LP gas regulator upward to a higher temperature by turning knob clockwise.

Check and make sure mushroom top on burner is secure and will not turn freely. If
it does, replace.
5.)
Burner may be blacked partially and not allowing enough gas supply to burn
evenly. Check flame color around mushroom. Inspect the flame with a mirror
under the machine to view burner area. If only a partial flame is visible, then
replace the burner.
