User Operating Instructions for Atmos InterOpen HE22 Condensing Boiler
First ask your installer to instruct you thoroughly about filling, de-
aerating and general use of the appliance and the total installation.
General operation
The Atmos InterOpen wall-mounted gas boiler is a balanced flue
appliance suitable for open vent systems with a header tank. The
appliance is designed for delivering heat to the water of a central heating
system and, if required, heating hot water via an indirect tank. The Atmos
InterOpen wall-mounted gas appliance is a modulating high efficiency
(Sedbuk B) boiler. This means that the power is adjusted to the heat
demand.
In the aluminium heat exchanger is an integrated copper circuit.
The appliance has been provided with an electronic burner controller that
controls the fan with the heat demand, opens the gas valve and ignites
the burner, continuously monitors the flame and controls it dependent on
the power required.
The Atmos InterOpen boiler has the CE quality mark and an IP44
enclosure.

Central Heating (CH) operation & Tank (if applicable)
The controller adjusts the fan speed, and hence the heating power,
according to the set CH supply water temperature, the latter being
displayed on the temperature display (adjustable between 30 and 90 °C,
using + / - buttons).
The appliance has a pump output. If the external pump (not supplied as
part of the HE22 appliance) is connected to this output, a pump overrun
time of 1 minute is provided (factory setting, but can be adjusted) to
dissipate the heat. Also, the pump will automatically run once every 24
hours to prevent it from getting stuck (if there is no heat demand).
