COMMISSIONING THE APPLIANCE
At the time of commissioning, complete all relevant sections of the Benchmark
Checklist located in section 17 of this document.
9.1
Filling and venting the appliance and the installation
9.1.1
CH system
CAUTION
When an additive is added to the CH water, ensure it is
suitable for the materials used in the appliance, such as
copper, brass, stainless steel, steel, plastic and rubber.
1.
Connect to 3 amp fused spur or an unswitched socket with 3 amp fuse.
2.
Fill the heating system feed tank and system.
3.
Bleed the air in the installation with the manual bleed screws on the radiators.
4.
Connect the appliance to mains.
The appliance may perform a self test:
2
(on service display).
The appliance will then go into wait mode:
-
(on service display).
5.
Check all couplings for leakage.
6.
Fill the condensate trap with water.
9.1.2
Gas supply
1.
Gas supply purged of air via test point D on gas valve (see illustration )
2.
Connect a suitable gauge to test point D .
Static or standing pressure must be 20mb.
If 20mb is not obtained DO NOT proceed with commissioning until supply
is rectified.
3.
If static pressure is correct fire the boiler and allow to reach working
temperature.
4.
Test working pressure by selecting test program “H”. See section 10.8, High
Setting. Working pressure must be 20mb +or- 1mb
If working pressure is less than 19mb appliance heat output will be reduced and
correct combustion readings may not be obtained. Do not adjust the air/gas
ratio. Correct gas supply to obtain sufficient working pressure.
NOTE
The inlet working pressure must be obtained with all other gas
appliances at the property working.
9.1.3
Combustion
The combustion for this appliance has been checked, adjusted and preset at the
factory for operation on the gas type defined on the appliance data plate. Although
the combustion is factory set please check the combustion as required by the
Benchmark Guidelines. If adjustment is necessary please refer to page 32. Do not
adjust the air/gas ratio valve
.
Having checked:
•
That the boiler has been installed in accordance with these instructions;
•
The integrity of the flue system and the flue seal, as described in § 8.5 and the
British Standards codes of practices, specifically BS 5440;
•
The integrity of the boiler combustion circuit and the relevant seals, as descibed in
§ 0 eg with a flue spillage mirror;
proceed to put the boiler into operation as follows:
1.
Set up the boiler to operate at maximum rate as described in § 10.7
With the boiler operating in the maximum rate condition check that the CO
2
value measuered at sampling point (X) complies with the requirements as
described in the table under § 10.8
Ensure that this inlet pressure can be obtained with all other gas appliances in
the property working.
9.1.4
Flue system
The flue system must be connected correctly to the appliance in accordance with the
manufacturer’s instructions. The flue termination should also be checked. Where
