THERMOSTAT
Before lighting the fire check the cold setting distance of the
thermostat. With the control knob at the minimum setting the flap
should be just closed as shown in Fig. 9. To adjust the distance slacken
the locking nut and adjust as necessary. When set correctly re-tighten
the locking nut. Ensure that the flap opens and closes freely as the
knob is turned.
Fit the side panels and the hood onto the appliance. Instructions for
this are enclosed with the panel pack. Replace any internal parts
previously removed.
PRE LIGHTING CHECK
Before initial lighting check the following points:
1. The bottom grate bars must all be fitted and should move freely and
easily when the riddling mechanism is operated.
2. The plates round the sides and back of the grate must be in position
and sitting correctly.
3. The throat plate must be fitted in the roof of the appliance.
COMMISSIONING
On completion of the installation and after allowing time for the fire
cement and mortar to dry out, the fire should be lit and checked to
ensure that the smoke and fumes are taken from the appliance up the
chimney and emitted safely. Also check all joints and seals.
On completion of the installation and commissioning please leave the
operating instructions with the customer and advise on the use of the
appliance.
ASSEMBLY
positioning the appliance in the fireplace if the fire surround is already
fitted.
Before fitting the boiler, remove the front firebars, the side and back
fire plates and the firebricks. Knock out the knock-outs for the boiler
tappings on the appropriate side of the firebox.
Remove the backnuts and fibre washers from the boiler tappings and
fit the boiler into the appliance. Place the fibre washers over the
tappings on the outside of the appliance and fit the backnuts,
ensuring that the boiler is held tightly against the rear inside face of
the appliance and that the top edge of the boiler is level or runs uphill
to the flow tapping.
When re-fitting the firebricks, note that the short side firebrick
supplied with the boiler must be fitted on the same side as the boiler
tappings. One of the original sidebricks is fitted on the other side, and
the rear brick is discarded. The firebricks are held in position by the
retaining brackets.
Replace the back fireplate, the side fireplates, the front firebar and
the throat plate.
Connect the boiler to the heating system ensuring that the flow pipe
rises from the boiler. Fill the system with water and check for leaks.
