Boiler Design
Description
Xtramax HE Model:
The boiler is designed to provide central
heating and instantaneous hot water.
Once the controls are set the boiler operates automatically.
Compartment or Cupboard Installations
Ventilation is not required for compartment or cupboard
installations.
Do not use the compartment or cupboard for storage.
The minimum clearances to fixtures are shown in
diagram 1.
Pluming from flue terminal
Like all condensing boilers it will produce a plume of
condensation from the flue terminal in cool weather. This is
due to the high efficiency and hence low flue gas temperature
of the boiler. It is normal and not a fault indication.
Electrical Supply Failure Reset Switch
The boiler will not work without an electrical supply.
Normal operation of the boiler should resume when the
electrical supply is restored.
Reset any external controls, to resume normal operation of
the central heating.
If the boiler does not resume normal operation turn the mains
reset switch off and on. If the boiler does not resume normal
operation after this the overheat stat may have operated.
+ A removable compartment door can be placed
at least 5mm in front of the appliance
