SECTION 5 - MAINTENANCE AND SERVICING
REMOVABLE BURNER
The burner mounted inside the F1 Gas Unit Heaters is removable type: this particular construction
characteristic allows the cleaning of the burner.
To clean the burner proceed as follows:
1. Cut off the electricity and gas supply;
2. Open the side panel of the heater;
3. Demount the hexagonal nut which connect gas pipe and the air blower (see figure 15);
4. Move the gas pipe and remove the gas nozzle (see figure 17);
5. Remove 4 nuts, which fix the casing of air blower;
6. Remove the deflector and gasket;
7. Loose 4 screws which fix the burner, and when the burner is leaned on the bottom unscrew and
remove them completely;
8. Insert a pipe inside the burner (ATTENTION: don’t bend the burner and don’t damage the
deflectors inside the burner) and use the pipe as a lever to pull it up and than to remove the
burner;
9. Clean the burner with compressed air;
10.
Reinsert the burner (MOTE: slot inside the burner must be in the upper position);
11.
Fix the lower screws first and than the upper ones. Cross-tighten the screws;
12.
Reinsert the diaphragm and relative gaskets;
13.
Fix the casing of the air-blower with 4 screws;
14.
Insert the nozzle and gasket in the holder of the nozzle;
15.
Screw tight the hexagonal which fix the gas pipe to the blower;
This procedure is to be applied once in 2/3 years by normal working conditions, or once per year
when there is a lot of impurities in the combustion air (example: “B type” installation of the heater in
factories with welding process).
The cleaning of the burner is to be done by
qualified personal.
Erroneous or not correct operation of the gas pipeline can cause dangerous gas leakages on
all circuit and particularly on the tamped segment.
