2. DESCRIPTION OF THE APPLIANCE

2.1 General

The Atmos InterCombi wall-mounted gas boiler is designed for delivering

heat to the water of a CH system and the domestic hot water.

The air supply and flue discharge can be connected to the appliance by

means of two separate pipes or a concentric connection.

The appliance has its own wall mounting strip, but can also be fitted to

an optional wall mounting frame that allows top connections. An optional

pipe mounting bracket for use with the wall mounting strip is available.

These are supplied separately.

The Atmos InterCombi wall-mounted gas boiler has the CE quality mark

and the Gas certification labels HE (Sedbuk A), SV , NZ (Solar

compatible) and CW Class 5 (Hot water performance rating 1 to 6,

where 6 is the highest) and IP44 Protection class.

It is possible to use the appliance for hot water or for heating only. The

system that is not used does not need to be connected.

The appliance as delivered is suitable for natural gas (G20). A

conversion kit for propane (G31) can be supplied upon request.

2.2 Operation

The Atmos InterCombi wall-mounted gas heater is a modulating high

efficiency boiler. This means that the power is adjusted to the heat

demand.

In the aluminium heat exchanger two separate copper circuits have been

integrated.

Because of the separated circuits for central heating and hot water, the

heating and the hot water supply can operate independently of each

other. The hot water supply has priority over the heating. They cannot

work simultaneously.

The appliance has been provided with an electronic controller that

controls the fan with the heat demand from the heating system or the hot

water supply, opens the gas valve and ignites the burner, continuously

monitors the flame and controls it dependent on the power required.

2.3 Operating conditions

A code indicates the operating condition of the appliance on the service

display of the operating panel.

- Off

The appliance is not operating, but there is electrical power. There is no

response to any demand for hot domestic hot water or CH water. The

frost protection is active though. This means that the pump starts

running and the heat exchanger is heated when the temperature of the

heat exchanger drops to 5°C.

When the frost protection is activated, code

7 appears (heating of the

heat exchanger).
