FAN SPEED CALIBRATION
Verification and calibration are necessary, in the case of transformation to other types of gas, in the extraordinary maintenance
phase with replacement of the PCB, air/gas circuit components or in the case of installations with flue extraction systems, with
horizontal concentric pipe measuring more than 1 metre.
The appliance's heat output is correlated to the length of the air intake and flue exhaust pipes.
This decreases with the increase of pipe length.
The appliance leaves the factory adjusted for minimum pipe length (1m coaxial).
- Activate flue test (Par. 3.15);
- Detect the flue signal ∆P (Ref. 16 and 17, Fig.52);
- Compare the signal ∆P and, if necessary, correct the S1 operating parameters with the following tables:
Victrix 24HY
G20 (x50 = RPM)
G31 (x50 = RPM)
Victrix 32HY
G20 (x50 = RPM)
G31 (x50 = RPM)
