GAS ADJUSTMENTS
Max and minimum gas pressure
adjustments can be made by means of
the gas valve respecting the values
shown on the tables relating to each
boiler for the type of corresponding gas.
Measurement is made using a pressure
gauge connected to the outlet of the gas
valve (6) and to the positive pressure
point located on the upper part of the
sealed chamber
(see illustration
alongside),
Then proceed as follows depending on
the gas valve fitted to the boiler.
- VALVE VK 4105 M
(with yellow protection cap)
Minimum pressure adjustment
- After interrupting the power supply
to the modulation coil (*), turn screw
"3" clockwise to increase pressure to
the burner and anticlockwise to
decrease it.
Maximum pressure adjustment
(operation to be performed after
minimum pressure adjustment)
- Do a d.h.w.request (open a tap) and
setting the temperature selector at
maximum.
Turn nut ”4” clockwise to increase
pressure to the burner and
anticlockwise to decrease pressure.
