If it is necessary to convert to a different
type of fuel (natural gas to propane and
vice versa), the boiler is reconstructed in
the following manner. This reconstruction
may be performed exclusively by a service
authorised by the manufacturer.
The following are performed:
1. Disassembly of burner from boiler;
2.
Replacement of all burner jets with
others (according to type of fuel).
3. Replacement of burner tubes with others
(according to type of fuel).
4.
Upon change from natural gas to
propane the cooling rods including
clamps are mounted on the burner tubes
– three rods on each tube. The rod in the
axis of the combined ignition electrode is
shortened by approx. 35 mm. Upon
change from propane to natural gas, the
Converting to different fuel
cooling rods must be removed.
5. Re-mounting of burner.
6. Setting of prescribed gas pressure to
designated boiler output (see chapter
“Preparing and starting the boiler”).
Together with setting the prescribed gas
pressure for the designated boiler output
the following are performed:
- upon change from natural gas to propane
setting of “SOFT-LITE” to MAX (fastest
opening of gas valve);
- upon change from propane to natural
gas setting of “SOFT-LITE” to MIN
(slowest opening of gas valve).
“SOFT-LITE” is located on the foot of
the body, on the side of gas outlet from
the valve. It has a dark plastic plug with
bayonet hook (turning and removal of plug
must be performed without use of force
