GENERAL NOTES
SEALED HEATING SYSTEMS
This boiler is fitted to a sealed heating system which is pre-pressurised. The optimum level for system pressure on a Greenstar CDi
Combination boiler is 1.5 bar indicated on the pressure gauge.
B
Check regularly that the pressure is maintained.
B
Contact your installer or maintenace engineer if a permanent significant drop is indicated on the pressure gauge.
PLUMING AND CONDENSATE DRAIN
This is a condensing boiler and the flue 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 via a pipe to drain. This pipe must not be blocked
or altered in any way.
PUMP ANTI-SEIZURE
If there has been no heating demand for 24 hours the boiler will run the system pump for a few seconds to reduce the possibility of
pump seizure during long periods of inactivity. This is usually more frequent during the summer months.
CLEARANCES
Your installer will have provided adequate space around the boiler for
safety and servicing access.
*600 mm service clearance required to a fixed surface
(**20 mm from removable door or panel)
B
Do not restrict this space with the addition of cubpoards, shelves
etc. around or next to the boiler.
VENTILATION
This is a room sealed boiler and does not require any air for
combustion from inside the property. If a compartment is built
around the boiler after installation, then this must be carried out as
described in the Installation Manual.
For information on how to “Re-pressurise the heating system” refer to page 10.
CAUTION:
Risk of damage to the boiler.
B
Do not operate the boiler if the flue terminal is
obstructed or damaged in any way.
