REMOVAL OF THE THERMOSTAT
To fit and remove thermostat on HSB boilers:
1. Pull the thermostat knob off the shaft.
2. Remove access cover plate, use a No.2 Pozi
screw driver and remove the M5 screw.
3. Remove the two M5 screws securing the ther-
mostat body, the thermostat and mount is now
free and you will be able to remove it from the
stove body.
4. On the rear of the stove remove the
thermostat sensor from its pocket and push
this carefully through the hole in the corner
cut-out of the stove.
5. Take care not to kink or fracture the copper
tubing (See Fig. 3).
6. Refitting of the thermostat is the reverse of the
above procedure.

SERVICE & MAINTENANCE
SETTING OF THERMOSTAT DAMPER
With the thermostat removed replace the control knob.
Rotate the control knob fully clockwise (as viewed with
the damper shaft to your left) until you reach the end of
possible travel.
Place the thermostat on a flat surface with the base of
the mechanism body on a small piece of
8mm thick
MDF or similar wood, see fig 3.
Now measure the high edge of the damper plate be-
tween the bench and the top edge of the damper, the
edge furthest from the control knob. This should be
29mm +/-1mm if not adjust as follows. Slacken off the
locking nut against the damper sprung boss and screw
the damper either in or out as required to achieve the
correct distance, once set re-lock and check the gap.
Repeat if necessary to achieve the correct clearance.
Once set re-fit as detailed previously.
Note:
You will need two open ended spanners for this
procedure, a 10mm spanner for the damper boss and
an 8mm for the damper lock nut.
Dependant on the stove size the damper plate may be
located in one of two hole positions. Please note this
before disassembling.
