HAMWORTHY HEATING LTD WARMWELL 500001091/F
With the pump fitted the system should be filled and
air locks cleared. Vent the radiators and check for
leaks.
If the system is unvented the pressurisation unit
should not be utilised for the initial filling. This
should be carried out using a WRC approved double
check valve and temporary-filling loop. In order to
comply with local Water Authority Regulations, this
loop must be disconnected when filling is complete.
Water treatments should not be fed through the
pressurisation unit unless permitted by the
manufacturer.
Check the expansion vessel cushion pressure as
detailed by the manufacturer's Installer's Guide.
11.4 Commissioning the Boiler
A competent person holding ‘CORGI’ registration
MUST be responsible for the commissioning of this
boiler.
Before attempting to commission any boiler, ensure
that personnel involved are aware of what action is
about to be taken and begin by making the following
checks: -
1) Flueway passages to chimney are clear.
2)
If necessary, remove the inspection cover and
ensure the boiler flueways are clear. Ensure
secondary heat exchanger passages are clear and
clean. Re-fit the cover.
3)
Adequate ventilation as per Section 7: Air
Supply (p10) exists in the boiler house.
4)
The system is fully charged with water, ready to
receive heat. All necessary valves are open and the
pump is circulating water. Ensure secondary heat
exchanger is purged of air.
5)
The pipework and valve arrangement is installed
to Hamworthy Heating recommendations in such a
way that water flow rates will be in accordance with
Figure 2.2 (p4).
6) The gas supply pipework is clear of any loose
matter, tested for soundness and purged.
11.5 Boiler Checks Prior To Lighting
NOTE!
Refer to Figure 2.2 (p4) for maximum gas
inlet pressure for normal operation. Information
relating to propane firing can be found in Appendix
‘A’ (p41).
NOTE! - All propane boilers are fitted with a low gas
pressure switch (set at 20mbar). Should the gas
supply pressure fall below this level, the boiler
will
not operate.
11.0 COMMISSIONING AND TESTING
For general layout of boiler refer to Figure 11.0.
11.1 Electrical Installation
A suitably competent person MUST check wiring.
Normal supply required is 230 volts AC, single
phase, 50 Hz. An isolator correctly fused at 10A
should be sited close to the boiler.
Access to the controls is achieved by rotating the ¼
turn latch and removing the door. Connections to
the boiler should pass through the 3 x 20mm wiring
gland plate. If a single header pump kit is used then
this power source must be constant and not
switched by any time clock. The boiler is supplied
with a remote stop/start circuit for time clock
operation.
Any other interlocks, i.e.
Pressurisation unit, BEM System should be
wired in series with the remote stop/start loop.
The site wiring terminal rail is marked with Live,
Neutral and Earth connections. See Figure 9.1
(p15) for details.
IMPORTANT READ THE WARNING NOTE
REGARDING EXTERNAL VOLTAGES.
The terminal rail is of the plug/socket type and can
be unplugged for wiring if required.
The main PCB is provided with four T rated fuses to
protect the following circuits – see Figure 11.1 (p26).
Main PCB F1 – T6.3A
Boiler controls F2 – T2A
Shunt Pump F3 – T2A
Sequencing Interface Module F4 – T2A
A schematic of the electrical control circuit(s) is shown in
Figure 9.1.
The fan motor is pre-wired to a plug/socket assembly
and must be connected to the controls assembly as
shown in Figure 9.1 (p15).
11.2 Gas Installation
For design see
Section 5:GAS SUPPLY.
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 or IGE/UP/1 , IGE/UP/1A and IGE/UP/2 as
appropriate.
11.3 Water Circulation System
For design see
Section 8:WATER SYSTEM.
The system should be thoroughly flushed out with
cold water without the pump in position. Ensure all
the valves are open.
