44 COMMISSIONING AND TESTING
A. ELECTRICAL INSTALLATION
1. Checks to ensure electrical safety should be carried
out by a competent person.
2. ALWAYS carry out preliminary electrical system checks,
i.e. earth continuity, polarity, resistance to earth and
short circuit using a suitable test meter.
WARNING. Whilst effecting the required gas soundness test and purging air from the gas installation open all
windows and doors, extinguish naked lights and DO NOT SMOKE.
45 INITIAL LIGHTING
B. GAS INSTALLATION
1. The whole of the gas installation, including the meter,
MUST be inspected and tested for soundness, and purged
in accordance with the recommendations of BS. 6891.
In IE refer to I.S.813:2002.
2. Purging air from the gas installation may be expedited by
loosening the union on the gas service cock on the boiler
and purging until gas is detected.
3. Retighten the union and check for gas soundness.
TO LIGHT THE BOILER
1. Check that all the drain cocks are closed, and any valves
in the flow and return are open.
2. Check that the gas service cock (B) is OPEN and the
boiler mains On/Off switch is OFF.
3. Fitting the Boiler Casing
The boiler casing must be refitted with the controls
support casing attached for alignment purposes. Lift
the boiler casing up to the boiler assembly, with the
casing top angled forward. Hook the top edge of the
boiler casing into the channel on the top of the boiler
assembly. Swing the bottom of the casing down and
secure with the 2 captive screws.
The casing must seat correctly and compress the
sealing strip to make an airtight joint.
Visually check the side seals but, if side clearances are
limited, then check that the top and bottom edges of the
casing are correctly located.
Note. If the Sealed System Unit is fitted remove the unit
casing in order to inspect the top casing seal.
To gain access to the gas valve:
a. Remove the controls support casing. Release the
controls support front fixing screws 3 turns only.
Remove the pod by pulling it forward to disengage
from the keyhole slots.
b. Remove the control box securing screws and swing
it down into the servicing position. See diagram B,
Frame 46.
4. Slacken the screw in the burner pressure test point (F) and
connect a gas pressure gauge via a flexible tube.
5. Swing the control box back into its working position.
6. Press the overheat thermostat reset button (J).
7. Switch the electricity supply ON and check that all external
controls are calling for heat.
8. Set the boiler thermostat knob (D) to position 6 and the
boiler Mains On/Off switch to ON. The fan will start. After
the fan has run for a few seconds the pilot solenoid valve
should open and the intermittent spark commence,
continuing until the pilot is established. The main burner
will then cross-light smoothly. If this sequence does not
occur, refer to the Fault Finding section.
9. Test for gas soundness around ALL boiler gas
components using leak detection fluid.
10. Operate the for 10 minutes to stabilise the burner
temperature.
The boiler is preset at the factory to its nominal rating.
Check the burner pressure against the values quoted in
Table 2 (page 2). The inlet pressure measured at the gas
control valve must be 37mb.
11. Set the main On/Off switch to OFF.
12. Switch the electricity supply OFF.
13. Swing the control box down into the servicing position.
14. Remove the pressure gauge and tube. Retighten the
sealing screw in the pressure test point. Ensure a gas
tight seal is made.
