6. Re- mount the cover.
MODEL 52 – REGULATION FOR MAXIMUM HEAT OUTPUT
To have:
the gas convector installed and connected to the electrical and gas
network.
1. Remove the cover.
2. Position the summer/winter switch (see ref. H of Figure 2 at page 13) on winter
mode.
3. Remove the plastic cover C of the gas valve (see Figure 19).
4. Connect a pressure gauge in position E of Figure 19.
5. Turn on the unit (see paragraph “START UP (HEATING)”) at page 15.
6. Exclude the pressure regulator closing completely the screw B (see Figure 19). In
this way the pressure to the burner is directly related to the network pressure; ensure
then to have a 30 mbar in the gas network (for gas G30) or a 37 mbar pressure (for
gas G31). The network pressure level can be reduced by using a special first stage
pressure reducers, placed close to the liquid propane tank, to reduce the pressure to
1,5 bar and a second stage reducer from 1,5 to 0,03 or 0,037 bar close to the unit
(reducers must be installed always outdoor).
7. Proceed with the pressure setting at the reduced heating output as indicated here
below.
MODEL 52 – REGULATION FOR REDUCED HEAT OUTPUT
8. Verify that B screw is completely closed.
9. Press max/min switch (see ref. G of Figure 2 at page 13). In this way the unit will run
at the reduced heat output.
10. Keeping unmoved B screw, set by means of screw A the pressure of reduced
heating power to the requested value (see Table 3 at page 11), in clockwise sense
to increase it and in the opposite sense to decrease it (use a screwdriver).
11. Relocate the plastic cover C.
)
After the setting, turn off and turn on the unit and verify that the pressures at the
burner are correct. If necessary repeat the operation.
After the setting operation it is obligatory to seal the screws of valve regulation.
12. Re- mount the cover.
