8.10 Fuel heating

In order to assure regular ignition and operation even at low tem-
peratures the burner has an oil heater fitted in combustion head.
The heater turns on when the thermostats close. The enabling
signal for burner start up comes through a thermostat on the noz-
zle holder once the optimal ignition temperature is reached. The
heating remains on during operation and cuts out when the burn-
er shuts-down.
