Installation Section – Page 14 
C. Polarity Check 
Appliance connected to mains supply and meter set of 300 Vac scale. Test at appliance terminal strip:- 
a) Test leads from L to N - meter reads approx. 240 Vac 
b) Test leads from L to E     - meter reads approx. 24OVac 
c) Test leads from N to E     - meter reads from 0.15Vac 
Thus the terminal marked L is the live terminal. If the low Vac reading is given on terminals other than N to E  
there is an electrical fault. 
Repeat the test at the appliance plug/inlet spur to check the wiring system up to the appliance and rectify any fault. If 
necessary repeat the test at the supply system socket/spur - if the fault also occurs at this stage then there is a house 
system fault which requires attention by the Electrical Authority. The customer should be warned not to use the 
appliance until this examination has been carried out. 
D. Resistance to Earth Check 
Appliance must be disconnected from mains supply and meter set on Ω (ohms) x 100 scale. All switches 
including stats, ‘On’ - Test leads from L to E - if meter reads other than infinity (∞) there is a fault which 
should be isolated. A detailed continuity check is required to trace the fault component. 
IMPORTANT 
This series of checks are the first electrical checks to be carried out during a fault finding procedure. On completion 
of the service/fault finding task which has required the breaking and remaking of electrical connections then the 
checks A. Earth Continuity, C. Polarity and D. Resistance to Earth must be repeated. 
8.2 TO LIGHT THE BOILER 
a) Fit the boiler thermostat knob (Accessory Pack G) onto its spindle and switch it to the off position. 
b) Check that the main electricity supply to the boiler is switched on. 
c) Turn on the main gas supply. 
WARNING: OPEN ALL WINDOWS AND EXTINGUISH ANY NAKED LIGHTS IN THE ROOM AND PUT 
OUT PIPES AND CIGARETTES. 
d) Break the union adjacent to the boiler main inlet cock, then open the cock and purge any air from the supply pipe. 
e) Close the cock, remake the union then re-open the cock and test for gas soundness using a soap solution. 
WARNING: DO NOT USE A NAKED FLAME 
f) Ensure that the system is full of water and that the pump and radiator isolating valves are open. 
g) Ensure that the time control, if fitted, is in an ‘on’ condition, and that the room and/or cylinder thermostats, where 
fitted, are set to high temperatures. 
h) Turn the control button on the gas control valve clockwise as far as possible (approximately 1/12th of a turn) and 
release it. This ensures the valve is in the off condition. 
I) Press and hold in the control button on the gas control valve, then press in the igniter button until 
a click is heard. Release the igniter button but continue to hold in the control button and check through the sight hole 
that the pilot has lit: hold in the control button for a further 20 seconds, then release it and the pilot should remain 
alight. 
NOTE: On first lighting, establishment of the pilot flame may be slightly delayed due to the presence of air in the 
pipework and several operations of the igniter button may be necessary. 
If the pilot fails to light or goes out at any time, immediately turn the control button clockwise as far as possible 
(approx. 1/12th of a turn), then release it and wait three minutes before repeating the lighting procedure. The control 
button should not be touched during this period. 
k) Turn the boiler thermostat on and to a high setting and the main burner will light. 
I) Set the boiler thermostat and the room and/or cylinder thermostat(s) and time control, where installed, to their 
required operating conditions. 
9. FINAL ADJUSTMENT 
A. Gas Rate and main burner pressure setting 
1) Fit a pressure gauge to the pressure test nipple on the gas control valve, see 

Figure 1

2) Turn on the boiler thermostat, then check that the burner pressure is in accordance with 

Table 1

3) If burner pressure adjustment is necessary, remove the screwed cap on the top of the control valve and turn the 
screw beneath clockwise to increase pressure or anti-clockwise to decrease. Re-fit the screwed cap when the pressure 
is correct. Shut down the boiler, remove the pressure gauge and tighten the screw in the pressure test nipple. 
4) With the burner set to its correct pressure, the firing rate given in 

Table 1

 should also be obtained and this should 

be checked by meter reading over a period of at least five minutes once the boiler is hot. 
B. Pilot Burner
