SWITCHING OVER TO ANYOTHER TYPE OF
GAS
During the course of their production, the boilers are
produced and calibrated for G20 type natural gas.
Switching the devices to another type of gas and
carrying out its gas technical calibration can only be
carried out by the brand service!
Switching over to another type of gas – e.g. G30
(propane) – involves the following:
Replacing the nozzles
o
Take off the door of the boiler
o
Screw the nozzles out of the collector and in
their place screw in the nozzles of the right size
for the gas type. Use the washers!
Gas technical calibration
o
Connect the pressure gauge on the measuring
stub (A).
o
Start the boiler in the manner introduced earlier.
o
Remove closing valve number 1 of the gas
valve.
o
With the help of bolt number 2, set the pressure
value to the value specified in the table (the bolt
under the closing bolt). By turning the bolt to the
right, pressure increases, by turning it into the
opposite direction, it decreases.
o
Remove the measuring device and put back the
closing bolts.
When switching the gas device to another gas type, the
size of the nozzle and the value of the gas pressure are
to be the same as the values specified in the table
introduced above!
o
Before and during calibration, check the
pressure of the tanked gas system.
o
Check the density of the complete pipe system.
o
Remove the label “Calibrated for G20” stuck
under the gas connection, and instead post a
label referring to the current gas type.
