(d) Ensure that all wiring connections are correct and that all terminal screws are tight.
(e) Insert a micro-ammeter into the meter jack (if fitted) on the burner programmer. This task should be
undertaken by a qualified service engineer.
(f) A barometric type draught stabiliser, if fitted in the flue, should be set for a draught of - 0.01 in. to 0.02
in. (0.025 mb to 0.05 mb) of water column pressure with the burner off.
(g) Open all the valves in the water feed line.
Switch on the feedwater pump motor and fill the boiler, see Section 3 - Operation.
The operation of the pump controls should be checked by using the boiler blowdown valve (located
at the rear of the boiler). When the water sight level gauge is reading half full, the pump will stop.
Open the boiler blowdown valve and slowly drain the boiler. When the water level falls below the
PUMP ON probe, the pump should start. If the pump does not start check the probe connections.
Close the boiler blowdown valve.
(h) After purging the gas lines of air, start the burner as detailed in Section 3 - Operation. Check the
readings on the micro-ammeter for the pilot and main flames, adjusting the primary air control to
obtain the maximum readings.
(j) Adjust the main air control gate to obtain a clean combustion.
(k) Observe the flame through the peephole between the electrodes and adjust the primary air
control so that the flame cannot be seen 'backing up' the blast tube.
(l) Check the operation of the low water safety controls as detailed in Section 3 - Operation.
(m) Adjust the steam pressure control to suit the boiler application. It should be borne in mind that boilers
are designed to operate most efficiently at their maximum operating pressure. When boilers are to
be operated below a pressure of 80 psi (5.5 bar) consideration should be given to the fitting of a
pressure reducing set. See 2.8 Safety Valve setting.
If the pressure control is fitted with a differential scale:
(i) Set the main scale to the maximum pressure required.
(ii) Set the differential scale to give the required pressure differential between the boiler cutting out
and restarting. If the pressure control has a fixed differential, i.e. no adjustable differential scale, set
the main scale to the maximum pressure required.
SETTING THE BURNER FOR LOW FIRE / HIGH FIRE, MODELS 50E AND 60E
The correct settings for low fire/high fire operation are obtained by making adjustments to the two stage
solenoid valve (Fig. 8) and the low fire steam pressure switch.
(a) Set the gas input to the boiler for correct input on high fire. This should be done where possible by
using the gas meter. Adjust the main air gate and top damper adjustment to obtain optimum
combustion conditions.
(b) Adjust the low fire steam pressure switch to cut out at approximately 5 psi below the setting of the
main steam pressure control (See Section 2.16 (m)).
(c) Adjust the two-stage solenoid valve to obtain a low fire gas input of approximately 80% of high fire.
Leave the air gate adjustments as for high fire.
(d) Refer to the adjusting procedure below on the two-stage solenoid valve.
