Introduction
WARNING:
It is important that the case (not the controls tray)
is not disturbed or removed other than for servicing by a
competent person.
Please read these instructions and follow them carefully for the
safe and economical use of your boiler.
The Micron FF series are fanned flue boilers designed to
provide central heating and indirect domestic hot water.
The boiler is fully automatic in operation having only one user
control, the control thermostat.
Gas Leak or Fault
Turn off the gas emergency control valve immediately. Eliminate
all sources of ignition, i.e. smoking, blowlamps, hot air guns etc.
Do not operate electrical lights or switches either on or off. Open
all doors and windows, ventilate the area.
Electrical Supply Failure
Failure of the electrical supply will cause the burner to go out.
Should this occur, operation of the appliance will normally
resume after the electrical supply is restored.
If the boiler does not relight after an electrical supply failure the
overheat safety cutoff device may need resetting, remove the
controls cover and press the reset button, refer to diagram 8.1.
Overheat Safety Cutoff
If the overheat safety cutoff device operates on any other
occasion than an electrical supply failure, press the reset button
as in “Electrical Supply Failure”. If the overheat operates again,
turn the appliance off and contact your installation/servicing
company.
Maintenance
To ensure the continued efficient and safe operation of the
boiler it is recommended that it is checked and serviced as
necessary at regular intervals. The frequency of servicing will
depend upon the particular installation conditions and usage,
but in general once a year should be enough.
