Settings and testing.
1. Check that the stop valves are closed.
2. Connect the heating coil to the steam source.
3. Open the stop valves.
4. Check that the pressure is shown in the pressure gauge correctly.
5. Make sure there are no leaks in the heating coil or in the tubes connected.
6. Check that the thermometer shows a temperature appropriate to the pressure in the pipe.
Gas burner
WARNING! All gas connections to the unit must be carried out by specialized personnel and
in compliance with current regulations.
WARNING! The regeneration air must not be contaminated by combustible substances in
the state of gas, vapor, fog or dust which, when mixed with air, create dangerous situations.
WARNING! The humid air outlet is the same as the exhaust of the combustion gases. For
this reason it is essential to install the pipes in accordance with local regulations.
The gas supply pipes must be equipped with adequate supports to reduce the load and the tension due
to their weight and movement.
The pressure at the inlet of the gas supply for the burner must be correct, see technical data section.
The regeneration air for the burner must be outside air (not recirculated) with a minimum oxygen
content of 20%.
Only gas with a sulfur content of maximum 30 ppm (silicone gel rotor) should be used.
The correct type of gas is identified in the label next to the main identification plate, see technical data
section.
Description.
Direct flame flammable gas burners are used on all dehumidifiers. The burner operates with natural gas
or propane (optional) and employs the regeneration air which supplies the oxygen necessary for
combustion. It is therefore essential to provide a flow of correct regeneration air to ensure that the
burner operates efficiently.
For optimal performance, the air for regeneration must contain at least 20% oxygen. The air coming out
of the burner can not be used. To keep the unit efficiency, it is also important that the humid air outlet
is positioned correctly, in order to prevent the humid air from contaminating the regeneration air.
The burner is mounted in the flow of regeneration air. The gas is mixed with the regeneration air which
penetrates into the space between the V-shaped mixing plates.
Behind the electrical panel, a spark ignition device and a flame detection probe are mounted near the
burner's combustion chamber. The flame detection probe uses the ionization principle to send a flame
signal to the burner safety control unit.
The operating principle with constant air flow and pressure drop in the burner ensures the correct mixing
of combustion gases and regeneration air.
