Pipe Thermostat; Commissioning Checks - Stanley Brandon Dry Installation And Commissioning Instructions

NOTE: Copper cylinder should be "finned-coil" type
with minimum capacity of 210 litres to B.S. 1566 &
B.S. 699.
Cylinder thermostat set to 60
motorised valve (see Fig.24).
INDIRECT SYSTEM ONLY
To off-load excess hot water generated during
long cooking periods, it may be necessary to
install a heat sink radiator.
We strongly recommend the fitting of a circulating
bronze pump on the return pipe to the boiler,
controlled by a pipe thermostat fitted on the flow
pipe within 6" (150mm) of the appliance.

PIPE THERMOSTAT

The fitting of a pipe thermostat to the common flow
pipe within 150mm (6") of the
recommended in order to activate the water
circulation pump when the boiler reaches 60
This will ensure that the return temperatures are
maintained and allow the pump to 'run on' to
transfer any residual heat to prevent possible
overheating.
NOTE: In line water conditioners fitted to the cold
mains supply both of chemical and magnetic type
are suitable for use with DHW cooker.

COMMISSIONING CHECKS

1. Check all items of packaging are removed from
ovens and the shelves are properly fitted.
2. Check that electrical wiring is correct.
3. Check that the cylinder and pipework are
purged of air and full of water with a suitable
safety valve fitted.
4. Check that the pipe stat is fitted as close as
possible to the boiler outlet.
5. Time switch must be on.

6. Check that the oven thermostat is functional.
7. Check that the gas supply is connected.
8. Check that the gas supply line is capable of
supplying the cooker.
9. Check that the ignition electrodes and ionisation
probes are set correctly. (See Fig. 26)

10. Turn on the gas supply ensuring that the cooker
is switched off. Test the whole gas installation
including the meter for soundness and purge in
accordance with B.S. 6891, purge not to exceed
50 mbar.
11. Check the gas supply and burner for leaks using
an approved leak detector spray and tighten if
necessary.
12. With the gas supply off switch on the burners.
13. Complete the start sequence to lock out
observing the correct operating functions.
14. Reinstate the gas supply and switch on the
burner to ensure that it fires correctly.
15. With the cooker operating on full flame check for
adequate gas supply by connecting a water
manometer to the nipples on the gas valve.
16. Similarly check the manifold pressures by
connecting the manometer to the test nipple
nearest to the burner head and adjust as
required.
17. When commissioning ensure that all doors of
the appliance are closed while in operation.
18. After a minimum of 15 minutes of continuous
operation with the burner still running, check
flue gas analysis.
