6.3 Flue Blockage Safety Device - Capillary
and Interrupter Electrical Leads
For transit the capillary is taped to the side of the boiler.
Remove tape and place capillary into cable clips provided, see
diagram 6.2.
Note: Capillary must not touch the heat exchanger side.
Secure the interrupter electrical leads so as not to strain them,
see diagram 6.2.
6.4 System Controls
The electrical installation must be in accordance with the
current issue of BS7671.
The electrical isolator must isolate both the boiler and system
controls.
6.5 Testing
Checks to ensure electrical safety should be carried out by a
competent person.
In the event of an electrical fault after installation of the boiler,
preliminary system checks must be carried out, that is, earth
continuity, polarity and resistance to earth as described in a
multimeter instruction book.

7 Commissioning
Please ensure the “Benchmark” logbook is completed and left
with the user.
7.1 Commissioning and Testing the Boiler
The whole of the system should be thoroughly flushed out with
cold water with pump removed. Make sure that all valves are
open. Refit the pump and fill the system. Examine for water
soundness and vent all air from the system, including the pump.
Caution. The following should be done by a competent person.
Identify the controls, refer to diagram 7.1.
Check that the gas cock “K” is closed, that is, slot is horizontal.
Open all windows and put out any naked lights, pipes or
cigarettes.
Purge air from the gas supply in accordance with the current
issue of BS6891.
Carefully unwind the thermostat capillary, insert the phial fully
into pocket “J” and secure the location washer behind the
retaining split pin, supplied in the loose items pack, see diagram
7.2.
Check that the mains electrical supply is switched off.
Set thermostat control knob “B” to “O”.
Remove gas test pressure point screw “G” and fit a suitable
pressure gauge.
Open gas cock “K”, slot vertical.
Note: Make sure the Flue Blockage Safety Device reset button
'N' is fully pushed in.
Turn gas control knob “A” to ' ' , the pilot and ignition position
and push in. At the same time press and release the ignition
button “C” until the pilot lights. At this stage air may be present
in the gas supply pipes and this operation may need to be
repeated. When the pilot burner lights, keep control knob “A”
fully pushed in for about 15 seconds. If the pilot fails to remain
alight, repeat lighting procedure, but now keep the control
button pushed in for a little longer.
If the control knob “A” is turned to ' ', a safety device prevents
relighting in an unsafe condition. No attempt should be made
to push knob “A” in until 3 minutes have gone by.
Note: Should the boiler fail to operate correctly refer to the Fault
Finding - Section 10.
Make sure that the pilot is alight and stable, see diagram 7.3 for
flame length, switch on the electrical supply. Set any remote
controls so that they are calling for heat. Turn control knob “A”
to ' ' main burner position. Set boiler thermostat control knob
“B” between “MIN” and “MAX” against the setting point on the
control box, the main burner will light. “MAX” is about 82
o C
(180 o F).
Test for gas soundness around boiler gas components with a
suitable leak detection fluid.
Set the burner gas pressure required, ten minutes after lighting,
see Data label “L” for settings or refer to Section 1.2. Adjust
screw “F”, diagram 7.1 to obtain the required heat input. Turn
clockwise to decrease. After adjusting, seal the screw.
If any doubt exists, the gas rate should also be checked at the
meter. This should be in the range of:
Hideaway - 40 - 1.3 to 1.8m 3 /h 38 to 50ft 3 /h
The rates are for guidance only, depending on the heat setting.
Stick the self adhesive arrow on to the data label against the
output the boiler is set to. The arrow is in the loose items pack.
Check the operation of the flame failure device as follows:
With the main burner alight, turn the gas control valve knob “A”
fully clockwise to its stop ' ', the main and pilot flames will go
out. Relighting will not now be possible. Before 60 seconds the
safety device will work, indicated by a “click” from the gas valve.
