1 - Convert the
boiler from Natural
Gas to Propane gas
or viceversa
Contents:
This conversion kit is composed of
the following elements, which are
necessary for the gas change:
- a label rating the new gas setting;
- this instruction sheet;
- an orice (see Table 1 for the
stamping reference);
Installing:
in order to make the gas change
please follow the instructions below:
1 - turn off power to the boiler;
2 - open the boiler’s casing;
3 - open the instrument panel (Follow
Section 2);
4 - Move switch #7 (see Figure 4)
from OFF position to ON position;
5 - turn on power to the boiler;
6 - on the boiler’s display you’ll see
followed by a number;
7 - using the push buttons and
set the input to:
- 61 to convert the boiler from LP
GAS to NATURAL GAS
or
- 62 to convert the boiler from
NATURAL GAS to LP GAS,
8 - push button to save the
new value;
9 - turn off power to the boiler;
10 - Move switch #7 (see Figure 4)
from ON position to OFF position;
11 - Replace the orice item “C” of
Figure 1 for the correct one for the
type of gas used. Verify that the
stamping on the orice matches the
gas type (See Table 1).
11 - turn on power to the boiler;
12 - Turn completely counter
clockwise the screw E of Figure 1;
13 - Checking gas supply pressure
following Section 3. The Gas supply
pressure must be between the
maximum and minimum value as
stated in Table 1.
14 - Verifying the CO2 rate and its
eventual adjustment following
Section 4: The boiler during its
normal operation, has a CO2
exhaust rate as shown in Table 1.
If not within range of value shown,
malfunctions will occur.
WARNING!!! The CO
(carbon monoxide) level should
not exceed values given in
Table 1, when combustion is
correct. Failure to comply with
this requirement could result in
severe personal injury, death or
substantial property damage.

WARNING!!! All
combustion measurements
must be performed with
calibrated equipment to ensure
proper reading and accuracy.
Failure to comply with this
requirement could result in
severe personal injury, death or
substantial property damage.
WARNING!!! If the
combustion levels are not
within the range given in
Table 1 for the ring rate, shut
the boiler down and contact
your distributor or the boiler
manufacturer (see reference in
the last cover page). Failure to
comply with this requirement
could result in severe personal
injury, death or substantial
property damage.
15 - Attach to the front of the boiler the
appropriate conversion label, found
in the conversion kit (see Figure 2
or Figure 3), stating the new type of
gas adjustment of the boiler.
a - Apply the label in Figure 3 if the
boiler has been converted to LP
GAS;
b - Apply the label in Figure 2 if the
boiler has been converted to
NATURAL GAS.
