IV – DISABLING THE PRESSURE REGULATOR
- Remove the protective lid
- 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 PRESSURE REGULATOR
- Remove the protective lid
- 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
plate. 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.

3.a Function
The water heater is used for the production of instant hot water.
The removal of hot water can be preformed by multiple taps.
By turning on the relative tap, the main burner switches on heating
the water that passes.
These devices with a modifiable flame are particularly suited for
usage with mechanical mixers and thermostats.
This water heater, in contrast with other water heaters with a fixed
flame, has a modulation valve to optimise the water heaters opera-
tion. It allows for the water to be heated using less water pressure
and gas by modulating the flame according to the amount of water
used, maintaining the water extracted at a constant temperature.
The water heater uses automatic variation that is "PROPOR-
TIONAL", able to change the gas consumption (modulating
the flame) to respond to the amount of water extracted.
Model 11: for the extraction of 2.5 to 5.5 l/m the temperature of the
water supplied remains at 60°C, (in this case the has valve sup-
plies the burner with the necessary quantity of gas proportional to
the water supplied), above 5.5 l/m to 11 l/m the water temperature
varies from 60°C to 40°C.
Model 14: for the extraction of 2.5 to 7 l/m the temperature of the
water supplied remains at 60°C, (in this case the has valve sup-
plies the burner with the necessary quantity of gas proportional to
the water supplied), above 7 l/m to 14 l/m the water temperature
varies from 60°C to 40°C
3.b Usage
Ensure that the gas tap and all water taps are switched off
- Turn on the Main gas supply tap or that of the gas tank if using
Liquefied Petroleum Gas (L.P.G.)
- Open the gas tap, not supplied with the device, placed imme-
diately before the water heater on the gas input pipe
– rotate knob A to the on position (
the way and keep it pressed
– press the piezoelectric button (positioned on the left side of the
water heater) until the spark ignites the pilot flame. When it igni-
tes keep the knob A pressed for 20-30 seconds. If the flame
does not ignite repeat the operation until the flame remains on.
– Rotate Knob A towards the large flame (
necessary to keep the knob pressed down lightly until the final
position is reached.
– From this moment the device is able to produce hot water on
request. Opening the hot water tap causes the main burner to
be ignited, and inversely, by closing the hot water tap the main
burner is switched off; but the pilot flame remains switched on
for future requests.
– If the main burner or pilot flame is accidentally turned off, the
gas valve automatically blocks the output of gas within 60 se-
conds so to avoid any danger. To return the device to an opera-
tional mode, repeat the steps above.
