VALVE ADJUSTMENT MULTIBLOC MB-DLE.../B01
1 Opening speed adjustment
2 Delivery
adjustment
3 Stabilizer
adjustment
4 Locking
screw
After loosening screw 4, turn the locknut 2 clockwise to obtain
minimum delivery, anticlockwise for maximum delivery. Once
adjustment is completed block screw 4 again.
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
00006,682 liters
Final reading
00006,947 liters
total
Q1
00000,265 liters
- 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
Ts1
= 1”95 x 10 = 19”5
- If, at the end of this checkup, the value is above 100, regulate the opening speed of the main valve.
