5.2 Use of the control panel

5.2.1 Using the control panel

Fig.8 Using the control panel

Important
OpenTherm controller.Your installer will advise you when this type
of control is connected to the boiler. If so, any change to the boiler
settings (e.g. heating temperature) must be made using the Open
Therm controller not the boiler control panel. Please consult the
user manual for the OpenTherm controller.

To increase or decrease boiler temperature and/or the domestic hot water
(DHW) temperature:

1. Turn the control knob with the symbol over it clockwise to in
crease the boiler set temperature. The set temperature will be
shown on the display screen.

2. Turn the control knob with the symbol over it anticlockwise to de
crease the boiler temperature. The temperature will be shown on the
display screen.

3. Turn the control knob with the symbol over it clockwise to in
crease the DHW temperature. The temperature will be shown on the
display screen.

4. Turn the control knob with the symbol over it anticlockwise to de
crease the DHW temperature. The temperature will be shown on the
display screen.

To reset the boiler:

1. Press the

button for approximately 1 second, holding the button
for more than 2 seconds the boiler will not reset. (see List of error co
des, page 21.)

5.3 Shutdown

5.4

Frost protection

Isolate the mains power supply at the fused spur unit.
Isolate the gas supply at the boiler valve.
Protect the boiler from frost.

Important
The boiler is not protected against frost once it has been shut
down.

Important
If it is anticipated that the boiler will not be used for a long period
or the property is to be unoccupied it is recommended that the
system be drained if the electricity and gas supplies are to be
turned off. Your installer will be able to offer advice.

Where possible, draining the system should be avoided. If the system is to
be unused during winter months several precautions must be taken:

Any parts of the system that are in unheated areas of the dwelling
should be fitted with a device such as a pipe thermostat or frost thermo
stat.
Power must remain supplied to the boiler and controls.
Gas must remain supplied to the boiler.

The boiler pump will operate if the system temperature drops below 7°C. If
the temperature falls to 4°C the burner will ignite and remain lit until the
temperature reaches 10°C. At this temperature the burner will extinguish
but the pump will continue to operate for 15 minutes. This feature will pro
tect the boiler and to some extent adjacent parts of the system but addi
tional devices must be incorporated to guarantee frost protection.

6 Maintenance

7679305 - 1 - 14082017 17

6.1 General

6 Maintenance

The boiler does not require any special maintenance. However, the boiler
must be serviced annually in accordance with the Installation and Service
Manual and the relevant section of the Benchmark Service Record com
pleted in order to maintain the warranty.

Important
Taking out a maintenance contract is recommended.

Caution
Maintenance operations must be performed by a qualified compe
tent person.
Use only Baxi genuine spare parts.

The painted panels should be wiped with a damp cloth and then dried
completely. DO NOT USE ABRASIVE CLEANING AGENTS.

6.2

Maintenance instructions

The central heating system should be checked regularly. Proceed as fol
lows:

1. Check the water pressure in the central heating system.

Important
If the water pressure is lower than 0.7 bar, the system must be
topped up.

See
Re-pressurising the system.

Important
If the water pressure drops below 0.5 bar the boiler will not work.

2. Check radiators for leaks and (especially in damp areas) for rust.

3. Open and close the radiator valves several times a year to ensure
they can still be rotated.

Caution
Only a qualified installer may clean the inside of the boiler.

6.2.1 Re-pressurising the system

If the water pressure is too low, the system must be re-pressurised.

The normal operating water pressure is between 1 and 2 bar. If the pres
sure exceeds 3 bar the safety pressure valve will operate and a fault is in
dicated. Ensure that the filling loop is disconnected if it is of a temporary
type. Contact your installer.

Fig.9 Water pressure

Fig.10 "Easy-Fill" - operate green lever as

shown to add water

It may be necessary to repressurise the system occasionally (when the
water pressure falls below 0.7). A filling device (the filling loop) will be fitted
on the system. This may be on the boiler itself, or on pipework near to the
boiler.

Important
If the water pressure requires regular re-pressurising a fault or
leak is indicated. Seek advice from your installer.

The Baxi 600 Combi is supplied with a special device, the "Easy-Fill" per
manent filling link.

1. Operate the spring loaded green lever to add water to the system.

Important
The system pressure is shown at all times on the pressure gauge
and can be viewed on the display when there is power to the boil
er.

2. When the figures on the display or needle on the pressure gauge in
dicate between 1 and 1.5 bar release the lever.

3. It is not necessary to remove any part of the permanent link.

4. When the correct pressure is restored the boiler will reset automati
cally.

7679305 - 1 - 14082017 25

10.1 Energy saving

10 Environmental

Tips on saving energy:

Do not cover radiators. Do not hang curtains in front of radiators.
Install reflective panels behind the radiators to prevent heat loss.
Insulate the pipes in rooms that are not heated (cellars and lofts).
Install loft insulation & double glazing.
Use draught excluders where necessary.
Upgrade any older boiler external controls.
Turn down room thermostats by 1°.
Turn off radiators in rooms not in use.
Do not run hot (or cold) water pointlessly.
Fit a water-saving shower head to save up to 40 % energy.
Take showers rather than baths. A bath consumes twice as much water
and energy.

10.2

Room thermostats and settings

Various models of room thermostat are available. The thermostat type and
setting affect the total energy consumption.

A few tips:

A modulating thermostat in combination with thermostatic radiator valves
saves energy and offers considerable comfort. This combination gives
you flexibility with the temperatures. Do not fit thermostatic radiator
valves in the room in which the room thermostat is installed.
Completely closing and opening thermostatic valve radiators causes un
desirable temperature fluctuations. Open and close thermostatic valves
in small steps.
Lower the thermostat to around 20°C. This reduces heating costs and
energy consumption.
Lower the room thermostat temperature temporarily if opening windows
to air the rooms.
If you are using an ON/OFF type thermostat, reduce the water tempera
ture value in summer (e.g. 60°C in summer and 80°C in winter).
When setting an hourly programmable thermostat, consider days when
you are absent or on holiday. Electricity production and energy savings
reach their optimum level with a programmed and activated timer pro
gramme.
