MAINTENANCE OPERATIONS
To keep the machine in efficient condition and guarantee a long lifetime of the heater, it is advisable to run some inspections
every year:
1. check the status of the start-up electrodes, detection electrodes and pilot flame;
2. check the status of fume exhaust and air intake ducts and terminals;
3. check the status of the venturi;
4. check and clean the exchanger and burner are clean;
5. check and clean the water trap
6. check the intake pressure at the gas valve;
7. check the function of the flame monitoring equipment;
8. check the safety thermostat(s);
9. check the ionization current.
NOTE: Operations at points 1, 2, 3, 4 and 5 must be performed after disconnecting the heater from the electrical mains and
closed the gas intake. Operations at point 6, 7, 8 and 9 must be done with the heater on.
1) Inspection of electrodes
Dismantle the complete pilot flame and use a jet of compressed air to clean the mesh and nozzle. Check the integrity of the
ceramic and use sandpaper to remove any oxidation on the metal parts of the electrodes. Check the correct position of the
electrodes (see drawing below). It is important that the detection electrode is at a tangent to the head of the pilot and not
inside it. The start-up electrode must discharge onto the mesh of the pilot burner.
2) Inspection of fume exhaust and air intake ducts
Visually inspect where possible or examine with specific tools to learn the status of the ducts.
Remove dust that forms on the air intake terminal.
3) Inspection and cleaning of the venturi
Remove any dirt at the mouth of the venturi with a brush, and be careful to not let it fall inside the piece.
4) Inspection and cleaning of the exchanger and burner
Perfect combustion in heaters prevents dirt. It is advisable, therefore, to not clean the exchanger and burner unless there are
exceptional circumstances.
An accumulation of dirt inside the exchanger could be revealed by a sizeable variation in the module gas capacity.
Should it become necessary to clean the burner and/or exchanger, all of the gaskets mounted between the burner and the
exchanger must be replaced.
5) Inspection and cleaning of the water trap
Clean the trap every year, and check the connections. Make sure there are no traces of metallic residue. If metallic residue has
formed, increase the number of inspections.
6) Inspection of intake gas pressure
Verify that the intake pressure at the valve corresponds to the value required for the type of gas that you are using.
This verification must be done with the heater on at the maximum heat capacity.
7) Inspection of flame monitoring equipment
With the heater operating, close the gas tap and verify that the heater blocks, signaled on the LCD display. Reopen the gas tap,
reset the block and wait for the heater to start back up.
