1.
Close the main gas tap to the boiler.
.
Remove the hatch on the control panel by opening it
straight out and carefully bending it upwards in the
centre so that the pegs are released (see chapter 6:12).
.
Remove the lower front plate (see fig 12). Lever with a
screwdriver in the groove on the bottom of the plate until
the tabs are clear. Then pull outwards/downwards until
the plate is free and can be removed.
.
Switch off the main current switch or remove the fuse on
the control panel. Set the thermostat knob in the ignition
position. Remove screw (fig 15 A) which holds the rod in
the automatic knob. Press the knob down and carefully
lift the rod from the knob.
.
Unfasten the springs (fig 13 A) which hold the sensor (fig
13 B) and overheating protection (fig 13 C) and remove
these from the boiler casing, se fig 14. Disconnect the
ignition cable from the ignition transformer (fig 13 D), as
well as the screw to the earthed connection (fig 15 B).
.
Remove the remainder of the screws, 13 off B6 x 9
(fig 15 C) in the burner plate.
7.
Disconnect the inlet gas pipe to the automatic unit
(fig 15 D) and remove the burner unit from the boiler,
see fig 16.
8.
Check that the front packing (fig 16 A) is intact before
the burner unit is replaced. Fasten the burner unit and
earth cable. Attach the inlet gas pipe to the burner unit
and tighten. Install the overheating protection, sensor
and ignition cable. Ensure that there is heat-conducting
paste between the sensor and the boiler. Check that
the capillary tube to the boiler thermostat, overheating
protection and ignition cable are correctly installed to
the right of the automatic unit, and are not trapped or
damaged.
9.
Fit the rod in the automatic knob and insert the screws.
Carefully turn the knob to the stop position and check
that the micro-switch ”clicks”, switches off.

Fit the fuse and switch on the main switch. Turn the
thermostat knob to the ignition position and check that
the indicator lamp flashes and that there is a spark at
the spark plug. Press down the thermostat knob and
turn to no. 7 on the scale. Check that the arm of the
micro-switch does not drag against the knob hub. (If
necessary adjust the micro-switch, see Chapter 6:10).
Turn to the stop position and check that the spark is
switched off and that the lamp stops flashing.

Install the lower front plate (fig 12), push the upper
parts under the edge of the control box, press the plate
inwards/downwards so that the tabs grip the boiler foot.
Fit and close the hatch.
