Baxi 11i - Gas Transformation

8
2.h Gas transformation
Transforming the product so it may receive a different type of gas
can be easily performed even while it is mounted. The instructions
for transforming and regulating the product to receive various types
of gas are below.
This operation must be performed by qualied personnel according
to law in force.
TRANSFORMATION FROM METHANE TO LPG
Transforming the product so it may receive a different type of gas
can be easily performed even while it is mounted.
Before any operation ensure that the gas supply is switched off.
I – SUBSTITUTION OF THE PILOT INJECTOR
- Disconnect the pilot ame tube (g. 8)
- Remove the pilot injector
- Insert the seal contained in the transformation kit (g. 9)
II – SUBSTITUTION OF THE BURNER INJECTORS
- Remove the screws that hold the pilot ame in position (g. 10)
- Remove the nut that holds the burner in place (g. 11)
- Remove the screws that hold the diffuser in place (g. 12)
- Unscrew the diffuser
- Unscrew the injectors and substitute them with those found in the
transformation kit
III – SUBSTITUTION OF THE MODULATION VALVE
- Loosen the cold water entry ramp nut on the exchanger
- Remove the 4 screws (B) of the gas valve (g. 13)
- Disconnect the microswitch’s cables
- Separate the water/gas valve set

- Extract the large spring and the small spring/modulation valve
set (g. 14)
- Substitute the modulation valve with the one in the kit
- Insert the valve and the large spring, taking care with the di-
rection of the insertion (g. 16) and making sure that the drilled
spring guide disc is in its correct position (g. 15)
- Remount the diffuser attaching it to the upper hole
- Remount the pilot ame
IV – DISABLING THE GAS ADJUSTER
- Remove the protective cap
- Regulate the supply calibration screws so that the maximum
amount of gas can pass (disk completely horizontal).
After regulating seal the lid with paint, lacquer or other such
materials.
Note: It is necessary to use a pressure regulator that operates at
30 mbar for Butane Gas and at 37 mbar for Propane Gas.
The above values must be measured using a barometer con-
nected to the devices pressure entrance.
TRANSFORMATION FROM LPG TO METHANE GAS
Execute operations I, II and III described above
IV – ENABLING THE GAS ADJUSTER
- Remove the protective cap
- Regulate the pressure screws so that the burner reaches the
pressure levels indicated on the technical data on page 3.
Note: ensure that the gas pressure is at 20 mbar.
After regulating seal the lid with paint, lacquer or other such
materials.
Check that all the disassembled parts are perfectly sealed
once the device is operational using a soapy solution.
WARNING – IMPORTANT Write on adhesive paper “device
transformed”, including the date of the operation, the name
and signature of the person who performed the transforma-
tion and attach it to the device near the older information pla-
te. In addition attaché the “Transformed Gas to…” sticker.
Attach it to the device over the previous similar sticker, on the
frontal part of the hood.
