15.1 Maintenance
Diesel fuel will degrade when stored for a long time. Operating the heater
with old fuel can affect the operation of the fuel pump. Run the heater once
per month for 15 minutes to refresh the fuel in the lines and keep the fuel
pump from malfunctioning.
Use proper type of diesel that is meant for the time of the year when the
heater is used. Summer grade diesel might cause failure of the fuel pump or
heater when it is used at low temperatures.
In the event that ignition is not detected within 90 seconds, the heater will
switch off and retry ignition after 20 seconds. In the event that two
sequential failures are detected, the heater will flash the light on the control
button to indicate an error.
In the event that the flame extinguishes during operation, the heater will
attempt to reignite itself two times before flashing the light on the control
button, indicating the type of error.
In the event that the voltage drops below 10/19 Volts or goes above 15/32
Volts (12 Volt/24 Volt system respectively), the system will switch off for
protection of the heater and battery.
