4.8 Combustion head adjustment
Installation operations are now at the stage where the blast tube
and sleeve are secured to the boiler as shown in Fig. 13 - A. It is
now a very simple matter to set up the combustion head, as this de-
pends solely on the output developed by the burner at maximum
power.
It is therefore essential to establish this value before proceeding to
set up the combustion head.
There are three adjustments to make on the head:
•
outside air R1;
• central air R2;
• gas deliveries R3.
In diagram (Fig. 14) find the notch to use for adjusting the air and
the gas, and then proceed as follows:
Outside air adjustment R1
Turn screw 4)(Fig. 13 - A) until the notch identified is aligned with
the front surface 5)(Fig. 13 - A) of the flange.
Gas adjustment R3
Loosen screws 1)(Fig. 13 - B) and 4)(Fig. 13 - B) and turn ring 2)
until the notch identified is aligned with index 3).
Central air adjustment R2
Turn choke 5)(Fig. 13 - B) until the notch identified is aligned with
screw 4)(Fig. 13 - B).
Tighten the screws 1) and 4) fully down (Fig. 13 - B).
Example
Burner output = 1515 MBtu/hr.
If we consult diagram (C) we find that for this output, the adjust-
ments are:
•
outside air: R1 = 5.3;
• central air: R2 = 2.7;
• gas: R3 = 0.7.
Once you have finished setting up the head, refit the
burner 4)(Fig. 15) to the slide bars 3) at approximately 4” from the
sleeve 5) - burner positioned as shown in Fig. 9 - insert the flame
rod cable and the ignition electrode cable and then slide the burner
up to the sleeve so that it is positioned as shown in Fig. 16.
Refit screws 2) on slide bars 3).
Secure the burner to the sleeve by tightening screw 1) and then re-
fit the split pin into one of two slide bars 3).
Reconnect the swivel connector 8) to the graduated sector 7).
Connect gas train and pilot train as shown in Fig. 16.
WARNING
When fitting the burner on the two slide bars, it is
advisable to gently draw out the high tension cable
and flame rod cable until they are slightly stretched.
