Preliminary Electrical Checks

1. Reference should be made to BS:EN 12828, 14336 and 5449
Section 5 when commissioning the boiler.
2. Prior to commissioning the boiler preliminary electrical system
checks should be carried out.
3. Remove the outercase, the bottom panel and lower the
control tray to gain access to the electrical connections (see
section 10.1).
4. These should be performed using a suitable meter, and include
checks for Earth Continuity, Resistance to Earth, Earth Loop
Impedance, Short Circuit and Polarity.
5. At the time of commissioning, complete all relevant sections of
the Benchmark Checklist at the rear of this publication.
11.2

Commissioning the Boiler

NOTE: The transit brackets - 3 off must only be removed
just before commissioning the appliance.
1. The engine is held securely for transit by 3 brackets (Figs. 48 &
49). To ensure that all 3 brackets are removed before firing the
appliance, two security measures must be overcome:
a) Firstly all 3 brackets are wired together. Remove the bottom
(left and right hand) brackets first (Fig. 49) by removing the
screws from underneath the engine and then undo the M6
screws securing the brackets to the back of the appliance.
Disengage the brackets and withdraw.
Remove the top centre bracket by removing the three M5
screws (8mm spanner) (Fig. 48).
NOTE: Please retain the screws and brackets in case resiting
the appliance is necessary. The center bracket should also be
refitted to protect the engine head during servicing.
b) This will release the second security measure now that the
top bracket has been removed. The push on connector can be
disengaged from the cut out and reconnected to the return
temperature sensor (Figs. 48a & 48b) (the appliance will not
operate until this reconnection is made, Error 40 will show).
2. Refit the control tray, the bottom panel and the outercase
before switching on the appliance.
3. Ensure that the filling loop is connected and open, then open
the heating flow and return valves on the boiler.
4. The system must be flushed in accordance with BS 7593 (see
Section 6.1) and the flushing agent manufacturers instructions.
5. Pressurise the system to 1.5 bar then close and disconnect the
filling loop.
6. Turn the gas supply on and purge the system according to in
GB BS 6891 (Natural Gas) BS 5482-1 (Propane Gas) and in IE
I.S. 813 "Domestic Gas Installations".
IMPORTANT : Lockout may occur and Error Codes E261 &
E262 displayed if the gas supply pipe is not adequately
purged.
7. Test for gas tightness.
