GENERAL NOTES

CENTRAL HEATING SYSTEM

During the first few hours of operation of the central heating system, check that all radiators are being heated at an even rate. Should the upper area of a radiator be at a lower temperature than the base of the radiator, it should be vented by releasing air through the venting screw at the top of each radiator. Make sure your installer shows you how to carry out the operation. Repeated venting will reduce the quantity of water in the system and this must be replen- ished for safe and satisfactory operation of the appliance. Should water leaks be found in the system or excessive venting be required from any radiator, a service engineer should be contacted and the sys- tem corrected.

SEALED HEATING SYSTEM

The appliance can be fitted to a sealed heating system which is pre-pressurised. In this case your installer will advise you on the min- imum and maximum pressure that should be indicated on the pres- sure gauge. See Fig. 3. Check regularly that this pressure is main- tained and contact your installer or maintenance engineer if there is a permanent significant drop in pressure indicated on the gauge. If the system loses pressure it should be re-pressurised as instructed by the installer.

NOTE: Some sealed systems do not require pre-pressurisation. If this type of system has been used by your installer he will advise you of any special maintenance that is required to ensure that the system is always full of water.

Should any water leaks be found in the system or excessive venting be required from any radiator, a service engineer should be contacted and the system corrected.

OPEN VENTED HEATING SYSTEM

The appliance may be fitted to an open vented heating system your installer will advise you. There is no need to check the pressure gauge.

CLEARANCES

Your installer will have provided adequate space around the appliance for safety and servicing. Do not restrict this space by the addition of cupboards, shelves etc. close to the appliance.
