GENERAL NOTES
SERVICING
The boiler must be serviced regularly by a competent, qualified person, such as a Worcester service engineer or alternatively a British Gas or other Gas Safe registered person.
Always use original spares, to help maintain the economy, safety and reliability of the boiler and to have the Service Record completed in the Benchmark checklist.
IMPORTANT: Ensure that the service engineer completes the Service Record in the Benchmark checklist after each service.
The completed Benchmark checklist will be required in the event of any warranty work and may be required by the local Building Control Inspector.
NOTE: The Benchmark checklist and service interval record can be found at the rear of the Installation, Commissioning and Servicing Instructions.
BENCHMARK STANDARD

INTRODUCTION
To get the best from your boiler please read these instructions carefully.
SEALED HEATING SYSTEMS
This boiler is fitted to a sealed heating system which is pre-pressurised. Your installer will advise you of the minimum and maximum pressure which should be indicated on the pressure gauge.
Check regularly that the pressure is maintained and contact your installer or maintenance engineer if a permanent significant drop in pressure is indicated on the pressure gauge. If the system loses pressure it should be re-pressurised and the cause of the fall investigated.
CENTRAL HEATING SYSTEMS
During the first few hours of operation of the central heating system, check that all radiators are being heated evenly. If the top of a radiator is at a lower temperature than the bottom then it should be vented by releasing air through the venting screw at the top of the radiator. Ask your installer to show you how this is done.
This boiler is fitted to a sealed system; repeated venting will reduce the quantity of water in the system and this must be replenished for safe and satisfactory operation of the boiler.
Should water leaks be found in the system or if excessive venting is required, then a service engineer must be contacted to inspect the installation and rectify any fault.
Only additives that are compatible with aluminium may be used in the system. Any incompatible additive used will invalidate the guarantee.
CONDENSATE DRAIN
This is a condensing boiler and the terminal will, at times give out a plume of water vapour. This is quite normal.
The boiler also produces quantities of condensate which is discharged regularly by a syphon within the boiler via a pipe to drain. This pipe must not be blocked or altered in any way.
GENERAL NOTES
CLEARANCES - VENTILATED
COMPARTMENT
Your installer will have provided adequate space around the boiler for safety and servicing access. Do not restrict this space with the addition of cupboards, shelves etc. next to the boiler.

ROOM THERMOSTAT
A room temperature controller and programmer should be fitted to control the central heating. Refer to the instructions supplied with the thermostat for information on siting and setting.
THERMOSTATIC RADIATOR VALVES
It is recommended that this type of valve is fitted to all but one of the radiators (or at least those in the sleeping accommodation). The remaining radiator, which must be where the room thermostat is located, should be un-controlled and must be left open. The thermostatic radiator valves should conform to the requirements of BS2767:10.
