User Operating Instructions for Atmos InterSystem HE26 & HE40C
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 InterSystem wall-mounted gas boiler 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 InterSystem wall-
mounted gas appliance is a modulating high efficiency 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 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.
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.
The appliance circulation pump has an overrun time of 1 minute (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).
