2.3 COMMISSIONING
This product is covered by the ‘Benchmark’ scheme and a
separate commissioning/service log book is included with
this product. This must be completed during commissioning
and left with the product to meet the Warranty conditions
offered by Gledhill.
On completion:-
1. Do ensure that the electrical connections (e.g. mains supply,
room thermostat) to the unit are correct and tight.
2. Do ensure that the functioning and control of the system is
explained to the occupant.
These Instructions should be placed along with the component
manufacturers instructions in the pocket provided on the rear of the
front panel. The front panel should then be refitted.
NOTE:- With sealed heating systems air is released from the water
during the first few weeks of operation. This must be vented and
the system repressurized.
Important Do’s and Don’ts
DO check the incoming mains water pressure and flow rate are
adequate. (The preferred range of mains pressure is 2-3bar).
DO check that all plumbing and electrical connections are in
accordance with the labelling on the thermal store.
DO check and ensure the air pressure side of the expansion vessel
is set at 1.0 bar (or as specified)
DO ensure the SysteMate is fitted on a sealed primary (i.e. closed)
system and the boiler is suitable (i.e. fitted with an overheat
thermostat)
DO adjust the ballvalve so that the water level in the appliance F &
E cistern when the system is cold is correct and does not overflow
when the appliance is at maximum temperature
DO turn down the servicing valve for the ballvalve in the F & E
cistern, once the system is finally filled, to the point where the
warning/overflow pipe will cope with the discharge arising from
a ballvalve failure.
DO make sure that there is adequate clearance above the
appliance F & E cistern to service the ballvalve.
DO ensure that the range rated appliances are set at the highest
output and the boiler thermostat is set to maximum for all
boilers.
DO insulate any exposed pipework in the SysteMate cupboard.
DO plumb the overflow/warning pipe (if fitted) in a 20mm internal
diameter pipe material which is suitable for use with a heating
F & E cistern, in accordance with BS 5449 (such as copper) and
ensure it has a continuous fall and discharges in a conspicuous
external position.
DO check the pump settings
a. The boiler pump should be set to give a temperature difference
across the boiler of 11°C or less.
b. The heating pump should be set to give a temperature difference
across the flow and return of not more than 11°C.
c. The hot water plate heat exchanger pump should be set at
maximum.
DO ensure that the bypass valve for the heating system is set
correctly.
DON’T use a combined feed and vent on SysteMate installations.
DON’T use pipe smaller than 28mm between the boiler and
the SysteMate when the boiler rating exceeds 20kW (about
68,000 Btu/h).
DON’T operate the ‘switch’ backup facility until the system is fully
fitted, vented and commissioned.
