Heater operation
Wallas heater 40 EA is designed especially for water circulation heating systems outside of the electricity network.
Light furnace oil, diesel oil or paraffin can be used to fuel the device. The heater is fed with fuel from a separate tank,
which is positioned below the heater. The heater is powered by a 12-volt battery, which can be recharged, for example,
by a solar cell, wind generator or a mains power adapter.
The combustion air is fed in from outside the device and its circulation is completely enclosed, and balanced with the
flue-gas exhaust head, which eliminates the effect of wind pressure on the combustion.
The heater's evaporation burner is activated automatically when the device is started. The glow plug in the burner
ignites the fuel that has been pumped into the burner. The glow time is fixed: it starts and ends automatically.
The heat sensor, in the heater, detects the flame's heat and lights the red LED to signal that the device has started.
All functions are controlled electronically. The fuel pump and combustion air blower are fully stabilised against voltage
fluctuations, which ensures clean combustion, regardless of changes in the battery voltage.
The heater is equipped with built-in overheat protection, which cuts the fuel feed if the device overheats.
When the heater is switched off, it cools down automatically. The cooling function ventilates the burner, and discharges
the flue-gases generated during the switch-off, to the outside of the cottage.
