MULTIBLOC MB-ZRDLE ..../B01 VALVE ADJUSTMENT
1 1st/2nd stage delivery adjustment lock screw
2 Stabilizer adjustment
3 Protective cover for initial fast-start adjustment device
4 2nd stage delivery adjustment
5 1st stage delivery adjustment
To adjust the 1st/2nd stage delivery loosen screw 1. Turning 4 and 5 anti-
clockwise increases the delivery. Turning clockwise reduces the delivery. Once
you have carried out the necessary adjustments re-tighten screw 1. To adjust
the initial fast-start mechanism remove the cover 3 and, using the rear of the
cover as a tool, rotate the pin.
CHECKING THE QUANTITY OF GAS AT IGNITION
To check the quantity of gas at ignition, apply the following formula:
Ts x Qs ≤ 100
where
Ts = Safety time in seconds
Qs = Energy freed in safety time expressed in kW
The Qs value is obtained from:
where
Q1
= delivery expressed in liters freed in no. 10 startups in safety time.
Ts1
= total safety time of 10 startups
Qn
= Rated output
To obtain Q1, proceed as follows:
- Detach the lead from the control electrode (ionization electrode).
- Read the gas meter before the test.
- Perform 10 burner startups; these correspond to 10 safety lock-outs. Read the gas meter again; by subtracting the first
reading, the Q1 value is obtained.
Example:
First reading
Final reading
total Q1
- By performing these operations, we can find Ts1 by timing no. 1 startup (safety lock-outs) by the no. of startups.
Example:
Actual safety time = 1"95
- If, at the end of this checkup, the value is above 100, regulate the opening speed of the main valve.
00006,682 liters
00006,947 liters
00000,265 liters
Ts1
= 1"95 x 10 = 19"5
