Table 16 Setting data natural gas and propane (with open air case)
NOTE: When checking combustion the C0

levels should be in accordance with the
Table 16 +/- 0.3%. If the levels are outside these tolerances adjustment to the levels
must be made in accordance with the tolerance in Table 16 (+/- 0.1%)
18 e. Check ionisation level on full and part load, measurement in volts between
terminal 4 and earth max 9 volts min 4 volts DC, see Fig. 23 (measurment is
linear 1V dc =1A dc).
NOTE: The full load adjustment changes the gas/air graph slope angle, whilst the part
load adjustment shifts the base point on a parallel axis; each adjustment therefore
alters the previous setting slightly. Repeat the process 18 a. to 18 e. and re-check the
values as many times as necessary until they fall into values as in Table 16.
