2.0 Operating the Boiler

2.1 Introduction

1. Your Baxi Combi 80Eco is a gas fired, room

sealed, powered flue combination boiler, providing

central heating for your home and mains fed

domestic hot water to taps and shower. It is fully

automatic and does not have a pilot light.

2. Priority is given to the hot water mode - when a

hot water tap is turned on the supply of heat to the

central heating circuit is interrupted.

2.2 Operating the Boiler

1. Ensure that the electricity and gas supplies are

turned on. Check that the central heating pressure

is between 0.5 and 1.0 bar (Fig. 3).

2. Turn the On/Off/Reset selector switch either

anti-clockwise from the off position (Fig. 5) to both

central heating and domestic hot water or

clockwise to domestic hot water only.

3. In either position the green power on neon

( ) will illuminate (Fig. 4).

4. Position (i) In this position the central heating

will operate according to demand or provide

domestic hot water when a tap or shower is turned

on (Fig. 6). Priority is given to domestic hot water.

5. Position (ii) In this position hot water will be

provided when a tap or shower is turned on

(Fig. 7).

6. The boiler will light automatically on demand.

7. The orange burner on neon ( ) will illuminate

when the boiler is operating and the main burner is

on (Fig. 4).

IMPORTANT: When the selector switch is in

the ‘0’(Off) position the electrical supply to the

boiler is isolated. The boiler will not operate and

the integral timer (if fitted) will require resetting

once the selector switch is set to either the

Position (i) or Position (ii).

2.0 Operating the Boiler

2.3 Temperature Control

1. Central Heating: The central heating hot water

flow temperature can be adjusted between 30°C

(± 5°C) minimum and 85°C (± 5°C) maximum.

2. Turn the control knob clockwise to increase the

temperature (Fig. 8).

3. In normal winter usage we recommend that the

central heating temperature be set at maximum.

4. Domestic Hot Water: The temperature of the

domestic hot water can be adjusted by turning the

control knob clockwise to increase up to a

maximum of 65°C (Fig. 9).

5. The temperature of the water is also dependent

on the water flow rate and the temperature of the

mains water coming into the house.

6. By slightly reducing the flow from the tap the

temperature will increase up to the maximum if

required.

7. The flow rate can be reduced down to as low

as 2.5 litre/min. The boiler will still recognise the

need to heat the water.

2.4 Safety Thermostat

1. Your Baxi Combi 80Eco is fitted with an

additional safety device, which shuts down the

boiler in the event of the system or the boiler

overheating.

2. If the device operates, the boiler will shut down.

To reset: Contact your Service Engineer - the

reset button is inside the appliance and resetting

by the user should not be attempted.

3. The cause of operation of the safety thermostat

should be determined by your Service Engineer.

2.5 Flame Failure Reset

1. The red flame failure neon ( ) will illuminate

in the event of the burner failing to light, or when

incomplete lighting of the burner occurs (Fig. 11).

2. Turn the selector switch fully anti-clockwise

against the spring pressure to the reset position

(R) and release (Fig. 10). Set the selector switch

to the required position to light the boiler.

3. If the flame failure neon illuminates repeatedly

a fault is indicated. Your Service Engineer should

be contacted as soon as possible.

2.0 Operating the Boiler

2.6 Central Heating System Pressure

1. The water pressure in the central heating

system is indicated by the pressure gauge.

2. With the system cold and the boiler not

operating the pressure should be between 0.5

and 1.0 bar. During operation the pressure

should not exceed 2.5 bar, and will normally be

between 1.0 and 2.0 (Figs. 12 & 13).

3. A pressure of 3 or greater indicates a fault.

The safety pressure relief valve will operate, at a

pressure of 3 (Fig. 14). It is important that your

Service Engineer is contacted as soon as

possible.

4. The minimum pressure for correct operation is

0.5. If the pressure falls below 0.5, this may

indicate a leak on the central heating system

(Fig. 15).

5. The system must be re-pressurised by your

Service Engineer.

2.7 To Shut Off the Boiler

1. For short periods: Turn the selector switch to

the Off position (Fig. 16).

2. For long periods: Turn off the selector switch

(Fig. 16), electricity and gas supplies.

If your home is to be left unoccupied for long

periods during cold weather the boiler and

whole system should be drained unless

equipped with frost protection.

3. Your installer will advise you about frost

protection and draining the system.

IMPORTANT: When the selector switch is in

the ‘0’(Off) position the electrical supply to the

boiler is isolated. The boiler will not operate

and the integral timer (if fitted) will require

resetting once the selector switch is set to

either the Position (i) or Position (ii).

3.0 Clearances and Check List

3.1 Clearances around the Boiler

(Figs. 17 & 18)

1. The minimum clear spaces needed around

the boiler measured from the casing are as

follows:

Top - 200mm

Bottom - 200mm

Both sides - 5mm

Front - 5mm (In Operation)

- 450mm (For Servicing)

2. These areas must not be obstructed in any

way. Blocking the clearance spaces may

result in the boiler overheating and damage

may occur.

3. The gas burning compartment of your boiler is

completely sealed from the room in which it is

fitted. Products from the combustion of gas are

vented to the outside through the flue terminal

which must be kept free from obstruction as this

would interfere with the correct operation of the

boiler.

4. The boiler may be installed in a cupboard if

these minimum clearances are kept. The

compartment should be large enough to house

the boiler and ancillary equipment only.

5. IT SHOULD NOT BE USED AS A STORAGE

CUPBOARD.

3.2 Check List

1. If a fault develops, or is suspected, call your

Service Engineer as soon as possible.

2. Go through the following check list before you

make contact.

a) Is the electricity supply on ?

b) Is the selector switch on (giving a green

“Power ON”light) and set for both Central

Heating and Domestic Hot Water ?

c) Is the red “Flame Failure”indicator lit ?

Turn the On/Off/Reset selector fully anti-

clockwise.

d) Is the gas supply on ?

e) Is the mains water supply turned on ?

f) Is the system pressure correct ?

g) Are the boiler temperature controls set high

enough ?

h) Is the time clock (if fitted) calling for central

heating ?

i) Is the room thermostat (if fitted) set high

enough ?

j) Are the radiator valves open ?
