GAS VALVE ADJUSTMENT MULTIBLOC GB-E 055
ADJUSTING START-UP GAS DELIVERY
Connect the pressure gauge to the pressure connector nipples at inlet 4
and outlet 3. Loosen the regulator by turning the main gas adjuster screw
2 anti-clockwise (when the regulator is loosened you will hear a click as
you turn the adjustment screw).
Start up the gas unit. Adjust start-up gas delivery via the start-up gas
adjustment screw 1. Turning clockwise increases delivery. Turning anti-
clockwise decreases delivery.
ADJUSTING MAIN GAS DELIVERY
Connect the pressure gauge to the pressure connector nipples at inlet 4
and outlet 3. Start up the gas unit. Burner delivery must be adjusted by
means of the main gas adjustment screw 2. Turning clockwise increases
delivery. Turning anti-clockwise decreases delivery.
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
