Dryer heater type This book deals with the Antti A1500 range of gas fuelled, direct driven dryer heaters. Channel burners are avail- able for two different gases; liquid gas and natural gas. The basic components of the two burners are similar. Refer to the nameplate affixed to the side of the machine for detailed information about the type of your heater.
The electric installations of the grain dryer's control centre must be carried out by an electrician. In addition is required a supply/reservoir of gas, and a pipeline from it to the burner, installed in accordance with the regulations. Antti-Teollisuus Oy 408102 06-2010...
- If the heater is protected against rain, it can be installed at a distance of at least three (3) metres from the grain dryer and other buildings. The length of the air duct between the glowing parts of the heater and the air channel end must be 6 metres. Antti-Teollisuus Oy 408102 06-2010...

The above-mentioned distances also apply if an existing dryer is converted to a vacuum dryer. Primarily, the same regulations apply to insulated and sheet-metal-clad StandAlone dryers that are installed out of doors than to silo element dryers that are constructed of steel.

THE BURNER OF THE HEATER MUST ABSOLUTELY BE PROTECTED AGAINST THE RAIN. IF THE BURNER IS NOT PROTECTED, ANTTI-TEOLLISUUS OY WILL NOT ASSUME ANY LIABILITY FOR THE CONSEQUENCES. Inlet air for the dryer heater must not be routed from inside the heater room, but the room must be equipped with openable doors for this purpose.
Natural gas 150.0 m If you know the energy content of the gas, you will be able to calculate exactly the maximum allowed gas volume. NOTE! The maximum allowed output of the heater must not be exceeded! Antti-Teollisuus Oy 408102 06-2010...
- The purpose of the pressure difference sensor is to monitor that the air flows through the heater and does not take any other route of lower resistance. Therefore, it must not be installed anywhere else than in the inlet air pipe after the heater. Antti-Teollisuus Oy 408102 06-2010...

If you apply drying temperatures higher than normally, the cut-off temperature will also be higher than normally. Install the sensor inside the pipe in the same manner as the drying air sensor, mentioned above in this manual. Antti-Teollisuus Oy 408102 06-2010...

Also ensure, that there is no direct line of vision from the sensors to the rear part of the combustion chamber. The heat radiation from the chamber transmits wrong measurement results to the thermostats. Antti-Teollisuus Oy 408102 06-2010...
- The heater fan cannot be switched off even via its own operating switch before the heater has cooled down below the "fan” temperature of the LTM thermostat (nor shall the heater blower be switched off from the main switch until the heater has cooled down). Antti-Teollisuus Oy 408102 06-2010...
GUARANTEE The guarantee period for the Antti-heaters runs for one (1) operating season. A five-year guarantee is granted to the fire surfaces of the heater. The guarantee covers defects in material and workmanship. Separate guarantee terms issued by the manufacturer apply to the oil burner.
