Atmos Warranty covers any material, construction or operation
faults that are found to be of original manufacturing origin. A full
statement of the Atmos Warranty can be found on
www.atmos.co.uk.
Atmos boiler warranty is two years from date of invoice or 12
months from date of installation, whichever is the later. This
warranty covers the cost of replacement parts and associated
labour. However the ignition & ionisation probe and the glass
fuse are excluded from this warranty. The warranty for the heat
exchanger is 10 years in total, but this covers the cost of
associated labour only for the first two years from date of invoice.
There is no carriage charge for the delivery of replacement parts
covered by the warranty. Any alleged faulty part must be
returned to Atmos carriage prepaid. Carriage will be credited if
the fault is found to be a manufacturer’s fault.
The serial number of the boiler must be supplied with any
warranty claim.
All products must be used in an appropriate application and
manner. This includes, but is not limited to, correct boiler sizing,
system design, system cleansing and use of corrosion inhibitors.
If the boiler installed is a combi boiler, an approved water
conditioner device must be fitted in areas where the water
hardness exceeds 200ppm, as required by Building Regulations.
The Benchmark Checklist & Service Record, found in the back of
the installation Instructions, must be filled in. Failure to install and
commission according to the manufacturer’s instructions and
complete the Benchmark Commissioning Checklist invalidates
the warranty.
The Warranty card must be completed and the signed Atmos
copy must be received within 14 days of installation together with
a copy of the Benchmark Commissioning Checklist, completed
by the installer. By signing the Warranty card the buyer agrees
that the goods have been delivered in a satisfactory condition.
Exceptions
8. In the event of full payment for a product not being received,
Atmos shall be discharged from all further contractual or
warranty obligations.
9. Surface and/or transport damage are outside the scope of this
warranty.
10. Any warranty provision shall not apply if Atmos determines that
the fault is due to improper application, use, neglect, accidental
damage or injudicious treatment, non-observance of instructions
contained in Atmos Manuals or due to improper repair,
adjustment, installation or maintenance or due to work carried
out by unqualified engineers. The warranty also lapses if the
Atmos boiler has not had a yearly service in accordance with
instructions.
11. This warranty shall not apply if the fault is caused by scale,
failure or abnormality of gas or water supply, or impact of any
external influence that adversely affects the normal operation of
the product. This shall include but not be restricted to
dehydration, abnormal or high voltage, and hard water.
12. Excluded parts are the ignition & ionisation probe and the glass
fuse as these are subject to wear and tear in normal use.

User Operating Instructions for Atmos InterOpen HE22 Condensing Boiler
First ask your installer to instruct you thoroughly about filling, deaerating and general use of the appliance and the total installation.
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 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).
General operation
The Atmos InterOpen wall-mounted gas boiler is 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 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 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.

Adjustment of CH supply temperature
Press the Temperature button (B) for approx 2 secs until the LED CH
and the display start to flash (the display shows the set temperature).
Change the temperature using the “+” and “-“ buttons, adjustable
between 30ºC and 90ºC.
Press the Reset button to store the changes (or press the On/Off button
to close the menu without storing the changes).
Note: After 30 seconds of no action, the changes will automatically be
stored and the controller will return to normal.
Note: If an Open Therm thermostat is used, or if weather dependent
control is used, the CH setting must not be adjusted manually.
Commissioning
The appliance should be installed and commissioned by an authorised
installer. Check the following:Never connect the appliance to the mains voltage without filling and
de-aerating the appliance and system.
1. Confirm that the appliance and system have been filled and deaerated.
2. Check that the electrical supply is switched on and the gas supply
is on.
3. Set the room thermostat lower than the room temperature.
Assuming that the appliance is switched off (horizontal mark on the
service display and remaining functions are off), switch on the
appliance with the on/off button on the display.
4. Set the room thermostat higher than the room temperature. The
appliance will start CH operation (5 on the service display) , heating
the CH supply water to the set temperature (see CH operation).
Faults
If one of the following simple faults occur, they may be remedied as
follows. In case of recurrence, or other faults, please contact your
installer.
The CH System does not reach the correct temperature:• Increase the temperature on the room thermostat.
• Open the radiator valves.
• Increase the CH water temperature by means of the Temperature
button (B) and the + and – button on the display (see Adjustment).
• De-aerate the system with the manual air vents on the radiators.
The fault LED above the Reset button flashes on and the
Temperature display shows fault code 1:The boiler is getting too hot, due to insufficient circulation.
• De-aerate the system with the manual air vents on the radiators.
After remedying the cause, press the Reset button for 5 secs and the
appliance will start-up again.
System Shutdown
Drain the appliance and the system when the mains voltage
has been disconnected and there is a chance of freezing.
1.
2.
Drain the appliance using the drain valve.
Drain the system at the lowest point.
Servicing the appliance
The appliance, the installation, the flue discharge and air supply should
be serviced every year by a qualified Service Engineer. The appliance
can be cleaned with a damp cloth. Do not use an aggressive or abrasive
cleaner.
Frost protection
In order to avoid freezing of the condensate discharge pipe, the appliance
should be installed in a frost-free room. In order to avoid freezing of the
appliance (heat exchanger), it has an appliance frost protection. When the
temperature of the heat exchanger drops to 5ºC, the burner will be
activated and the pump will start running until the temperature of the heat
exchanger reaches 10ºC. When the system (or a part of it) can freeze, a
frost thermostat should be installed in the area to be protected. Connect
this according to the wiring diagram (see also the Installation instructions).
Note!
The external frost thermostat is not active when the appliance has been
switched off at the operating panel or when the mains voltage has been
interrupted.
