1OPERATION OF THE APPLIANCE
The purpose of the Intergas Combi Compact ECO RF wall mounted gas fired boiler is to heat water and to supply it to the central
heating (CH) system and the domestic hot water (DHW) taps. Any use de iating from the intended use by the manufacturer may result
in product damage or unsafe situations and will oid the warranty.
The heat exchanger comprises of two separate systems for central heating and DHW. The appliance is fitted with a modulating control.
This means that the power is adjusted in line with the required heat, the boiler controller responds to each call for heat from the heating
/DHW system by igniting the burner and monitoring the flame.
1.1 Operation of the central heating
The call for heat arises as a result of the room temperature being lower than the temperature set on the room thermostat. If at that time
the appliance does not ha e a call for DHW, the appliance comes on in central heating mode. The central heating temperature control
modulates on the basis of the set central heating supply temperature. This means that when the desired central heating supply
temperature is approached the appliance adjusts the power. The pump for the central heating has a post purge period of 1 minute. The
post purge period may be changed if desired. The pump runs automatically for 10 seconds once e ery 24 hours to pre ent blocking.
1.2 Operation of domestic hot water supply
The DHW system is started automatically as soon as more than 2 litres of water per minute are drawn. During deli ery of hot tap water
no heat is supplied by the appliance to the central heating system.
For purposes of fast deli ery of hot tap water a DHW comfort function has been installed in the controller. This function maintains the
temperature of the heat exchanger. The DHW comfort function has the following settings:
On: ( LED on) The appliance’s DHW comfort function is turned on continuously. In this mode the heat exchanger will be kept on
temperature to assure instant deli ery of hot water.
Eco: ( LED on) The appliance’s DHW comfort function is an intelligent system. The appliance will adapt to the pattern of use of hot tap
water. As a result, the temperature of the heat exchanger will only be maintained in periods during which domestic hot water was drawn
on pre ious days.
Off: (Both LEDs off) The temperature of the heat exchanger is not maintained, as a result of which the deli ery of hot tap water takes a
little time. If there is no need for rapid deli ery of hot tap water, the DHW comfort function can be switched off.

•The on/off key closes the settings menu without storing the changes.
•By pressing the button the new times will be stored in the boiler controller. In the display appears [P] for a short period.
The maximum CH supply temperature. Can be set between 30°C and 90°C (standard setting 80°C).
Low setting for moderately cold weather, high setting for colder weather.
DHW temperature. Can be set between 40°C and 65°C (standard setting 55°C).
All other alterations of settings of the boiler may only be carried out by your installer.
3START-UP
Once the appliance has been connected to water, gas and electricity supplies and
checked by an authorised installer, the appliance can be started.
Please check the following points:
•The central heating system and domestic hot water system must be well filled and bled.
•The appliance must be switched off (Horizontal dash on ser ice display, other LEDs off).
•The water pressure in the central heating system must be between 1 and 2 bar (Shown on the temperature display).
Ne er switch the appliance on if the appliance, the CH system and the DHW system ha e not been completely filled and bled.
•The room thermostat must be set below the temperature in the room.
•The gas tap must be open.
•Switch the appliance on with the on/off key in the display (The LED lights up, and the ser ice display goes out). The appliance
may now heat up for purposes of the DHW system until the heat exchanger reaches the set temperature.
•Set the room thermostat higher than the actual room temperature. The appliance will fire for purposes of the CH system.
4FAULTS
If the following simple appliance faults occur, they can be resol ed as follows. In the case of repeated occurrence or other faults
always notify your installer.
1. The CH system does not heat up or does not ecome sufficiently warm:
•Increase the temperature setting at the room thermostat.
•Open the radiator al es.
•Increase the CH water temperature setting using the and the and key on the operating panel (see §2).
•Bleed the appliance and installation and check the CH water pressure.
2. The domestic hot water supply does not ecome hot or hot enough:
•Open the domestic hot water tap further.
•Set the domestic hot water temperature higher using the and the and key on the operating panel (see §2).
3. The fault LED a ove the reset key is flashing. The following codes are indicated on the display (4):
•1 The appliance becomes too hot, there is insufficient flow. Open the radiator al es, bleed the appliance and
installation and check the CH water pressure. If necessary top up (see §0 )
•4 The burner does not light. Consult your installer.
After rectifying the fault press the reset button and the appliance will start up again. For the meaning of the other operating and
fault codes please refer to the installation instructions. If, within a short period the same fault reoccurs your installer has to be
informed and requested to check and/or maintain the boiler.

5FILLING AND BLEEDING THE APPLIANCE AND INSTALLATION
NB: Switch the appliance off with the key. Do not switch the appliance on again until after filling and bleeding.
5.1 Central heating system
In order to guarantee a successful operation of the CH installation the water pressure in the system in case of a cold system should be
between 1 and 2 bar (Indicated on the temperature display when the appliance is in off mode ( - on display)).
If the pressure is too low, the system should be topped up.
If the pressure comes below 0,3 bar when the appliance is acti e the water pressure alue will be displayed (flashing digit) instead of
the time read-out. The system should be topped up.
Proceed as follows:
•Connect the filling hose to the drinking water tap and fill the hose with water until there is no longer any air in the hose.
Filling is only allowed ia an appro ed filing loop that has check al es fitted.
•Connect the filling hose to the filling / drain tap at the bottom of the appliance.
•Open the drinking water tap and then the filling / drain tap.
•Fill the appliance and the system until a cold water pressure between 1 and 2 bar is reached.
•Close the filling / drain tap and then the drinking water tap.
•Bleed the system and the appliance.
The appliance bleeding point is located at the top left on the appliance
The system can be bled via the bleed taps on the radiators and/or an air bleed in the piping
•Check that after bleeding the system the water pressure in the installation is still between 1 and 2 bar; if not, repeat the procedure.
If the system has to be filled more frequently than a few times a year, notify your installer since this means that there is probably a leak.
5.2 Domestic hot water supply
Pressurise the DHW part of the appliance by opening the main tap and/or the inlet assembly.
Remo e air from the appliance and the pipe work by opening a hot water tap. Lea e the tap open until all the air
has disappeared from the appliance and the pipe work. Close the hot water tap.
Check the connections for leakage.
5.3 Frost protection
To pre ent freezing of the condensate drain, the appliance should be installed in a frost-free room.
The appliance is equipped with frost protection which, as long as mains current is present, switches on the CH pump
and if necessary the burner when the heat exchanger temperature falls too far.
NB: If an internal or external frost thermostat has been installed in the system and connected to the appliance, it is not acti e when the
appliance has been switched off at the operating panel ( - on ser ice display).
5.4 Condensate outlet.
The condensate outlet shall under no circumstances be modified or blocked. When a condensate neutralisation system is installed this must be
maintained and ser iced in accordance to the regulations pro ided by the supplier of the condensate neutralisation system..
6MAINTENANCE
The appliance can be cleaned with a damp cloth. Do not use aggressi e or abrasi e cleaning agents or sol ents.
