2 INTRODUCTION
2.1 Purpose
These stationary used oil fired heaters are direct fired heaters with thermal protection, heat exchanger, combustion air fan, flue stack connection with T-piece and draught regulator and hot air fan. The A T 500 is equipped with a connection for a room thermostat The hot air heaters have been tested at sea level at a temperature of 68 °F.
2.2 Working principle
The stationary used oil fired heater is equipped with three electric motors. The first electric motor drives a fuel pump, which extracts fuel from the fuel tank. The second electric motor drives the combustion air ventilator, which blows the combustion air into the combustion chamber. The third electic motor drives the hot air fan, which draws the surrounding air around the combustion chamber and heat exchanger. The hot air is blown into the space to be heated.
Diesel oil is poured manually on a burner dish, which is ignited with a burning paper pellet. As soon as the burner dish is at the right temperature, the pump thermostat activates the fuel pump; the control light flashes on. The fuel pump pumps the used oil onto the burner dish. The used oil evaporates due to the temperature of the burner dish. The gas vapour burns. A thermostat switches on the hot air fan motor to blow hot air into the space to be heated. The pump thermostat switches off the fuel pump when a failure causes the heater to overheat. The fuel pump is switched off when the heater is switched off. The hot air ventilator runs until the combustion air thermostat switches off the ventilator: this allows the heater to cool down. The maximum thermostat switches off the heater when the temperature gets too high. The fuel supply has an overflow that ensures that the used oil flows back into the fuel tank when the fuel pipe is blocked. The overflow protection switches off the fuel pump when the burner dish overflows.

2.6 Thermostat
The heater has the following thermostats:
Pump thermostat
When the burner dish is sufficiently pre­heated, the fuel pump starts up.
Hot air thermostat:
The thermostat starts the hot air fan when the heater reaches a certain temperature.
Maximum thermostat
The thermostat stops the fuel pump when the hot air temperature gets too high.

4.1 During operation Caution
Do not operate the heater in hot
weather to burn oil.
Do not burn used oils other than
generated on the premiss of the owner, unless written authorization is obtained from the regulatory authority.
Hot
Do not touch the flue stack or blower outlet! The flue stack and blower outlet get hot during operation!
4.2 Switching off
Switch off heating:
1. Switch the rocker switch to "0".
The fuel pump stops running. The control light turns off.
Caution
After switching off the heater it will run for several minutes, until the fuel on the burner dish is used up. In the meantime the hot air fan and the distributor fan keep running. These fans cool the heater until it has sufficiently cooled down (after 10 to 30 minutes). Both fans will stop around the same time.
