replace or re-charge your battery.
Damaged thermostat
- Make sure thermostat is connected properly.
- If burner fan does not come on

properly to burner unit. Take cover off
pressure switch by unscrewing the 4 screws
on the front part of the switch (switch is

contacts that conduct current, push on the
little button found on the micro switch
(button is located directly above the part that
attaches directly into pump).

If burner does not come on, make sure
there is current going through switch
(consult a professional for this if you do
not know how to do this properly as
you can get severely injured by the
electrical current connected to your
machine). If current properly flows
through pressure switch to burner,
check ignitor.
Damaged ignitor
- Please call a repair center for help to
conduct tests on the ignitor.
- If you see vapor coming out the
top of the coil when you try to turn
the burner on while the machine is
in use, fuel is passing through the
system properlybut the ignitor is
unable to produce a spark.
Replace the ignitor.
- If you don’t see vapor, check the
fuel line.
Plugged filter or no fuel
- Make sure you have enough fuel in the tank.
- If you have fuel, make sure the filter
and fuel line are not plugged or
damaged.
