CONVERSION OF GAS
TYPE
Conversion of the boiler
from natural gas to LPG
and viceversa must be
performed by qualified
personnel only.
Conversion is performed
as follows:
a.
turn off the main
power switch;
b.
close the gas cock;
c.
substitute the jets on
the main burner as
follows:
•
undo the gas pipe 5
(fig.1) from the burner
manifold using a size
24 spanner;
•
separate the burner manifold 2 from the burner ramps 1 by undoing the 4 screws 3 using a Philips screwdriver;
•
fit new jets 4 to the burner suitable for the type of gas the boiler will run on using a no. 7 spanner. The jets must be fitted
with new gaskets;
•
reassemble the entire burner unit. Use the soapy water method to check for gas leaks each time gas connections are
dismantled and reassembled;
d.
calibrate the new max. and min. settings for the modulator.
e.
replace the gas setting plate that indicates the type of gas and nominal pressure for the boiler. When converting the boiler
to work with a different type of gas, remove the existing plate and replace it with the new one supplied in the conversion kit.
