Operating Switch can monitor fuel levels to advise
when refueling is necessary.
Press and hold the Fuel Reservoir button to select a

To improve start ability on initial start-up, the PH41A
air heater has a fuel priming phase.
Press and hold the “Start / Stop” button and hold for
approximately 3 seconds.
Upon hearing an audible beep and “POLR” appearing
on the screen, release the “Start / Stop” button.
The heater will now enter into a Fuel Priming mode. It
will rapidly pulse 500 times then attempt a start up.
If the system is sufficiently primed before this 500
pulse count is completed, simply press and hold the
“Start / Stop” button to switch off the heater.
This process can be repeated as necessary.
To avoid flooding of the combustion chamber,
this process should only be used when priming is
required.
