UNIT DESCRIPTION

2.1

General

The Rotex RKOMB*AAV1HAAV1H wall-mounted gas boiler is a closed unit. The unit is
intended to provide heat to the water of a CH installation and the domestic hot water
installation.
The air supply and combustion gas outlet can be connected to the unit by means of
two separate pipes. A concentric connection can be supplied upon demand. The unit
was tested in combination with the combi feedthrough, but the unit may also be
connected to combi feedthroughs which meet the universal test standards for combi
feedthroughs.
The unit can be connected to an assembly bracket if required, a frame with top
connection, and various installation sets. These are provided separately.
The Rotex RKOMB*AAV1H wall-mounted gas boilers have the CE quality mark,
electrical protection class IP44.
It is possible to use the unit solely for warm water, or solely for heating. The system
which is not in use, does not need to be connected (see par. 7.2).
The unit is delivered for natural gas (G20) as a standard. On request, the unit can also
be provided for propane (G31).
2.2

Functioning

The Rotex RKOMB*AAV1H wall-mounted gas boiler is a modulating high-efficiency
boiler. This means that the power is modulated to suit the required heat demand. In the
aluminum heat exchanger two separate copper circuits are integrated.
The separate circuits for CH and warm water allow the heating and warm water supply
to function independently. The hot water supply takes precedence over the heating.
Both cannot work at the same time.
The unit is fitted with an electronic boiler controller machine, which operates the fan at
every heat requirement of the heating or the warm water supply, opens the gas valve,
ignites the boiler controller, and continuously monitors and regulates the flame,
depending on the requested power.
