Draught Regulator; Putting The Boiler Into Operation - Instructions For A Service Organization - ATTACK FD20 Instructions For Use Manual

12 DRAUGHT REGULATOR

Draught regulator – the thermostatic regulator is equipped with a thermostatic head adjustable
between 30 and 100 ° C.
Screw the regulator into the ¾" opening of the front head and put it with red index on the upper
part. The lever with the chainlet should be introduced in the regulator holder after removing the
plastic lock. If the joint which fixes the lever with the chainlet is taken out, take care in assem-
bling it again in the same position.
After adjusting the knob to 60°C, block the lever with the chainlet in a slightly inclined position
downwards so that the chainlet will be in axis with the air gate damper. For the adjustment of
the regulator that basicly depends on the determination of the chainlet length, proceed in the
following way:
•
adjust the knob at 60°C,
• burn the boiler with open air gate damper,
• when the temperature of heating water reaches 60°C, fix the chainlet in such a position that
the air gate damper will be open with the opening of cca.1mm.
After this setting the regulator is calibrated and it is possible to choose the desired operating tem-
perature by a rotating head.
13 PUTTING THE BOILER INTO OPERATION – INSTRUCTIONS
FOR A SERVICE ORGANIZATION
WARNING: Putting the boiler into operation can be performed only by a service organi-
sation certified for this activity.
Checking activities before start
Before putting the boiler into operation it is necessary to check:
a) filling the heating system with water (check by a manometer) and tightness of the set
b) connection to the chimney - this connection can only be carried out with the approval of a
chimney-sweeping company, to measure the draught of the chimney by a chart of fuels
Filling the heating system with water:
• Water hardness must correspond to standards and in case of unsuitable hardness it is necessary
to treat water
• Heating systems with an open expansion tank enable a direct contact of heating water with
the atmosphere. In the period of heating expanding water in the tank absorbs oxygen that
increases corrosive effects and in the same time water is evaporated significantly. To refill,
only water treated to values by STN 07 7401: 1992 can be used.
• The heating system must be thoroughly rinsed, to wash out all the dirt.
