GENERAL NOTES

GENERAL NOTES

To get the best from your boiler. please read these instructions carefully. 

CENTRAL HEATING SYSTEMS

During the first few hours of operation of the central heating system, check that all radiators are
being heated at an even rate. 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. Repeated venting will reduce the quantity of water in the
system and this must be replenished for safe and satisfactory operation of the boiler.

When excessive venting or water leaks are found in the system you must contact a service engineer
to inspect the installation and rectify any fault.

Only use additives compatible with the boiler and system. Use of incompatible additives can cause
damage and will invalidate the boiler 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 via a pipe to drain.
This pipe must not be blocked or altered in any way.

CLEARANCES - SERVICE

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 must be fitted to control the central heating. Refer to 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.
