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 "PROPORTIO-
NAL", able to change the gas consumption (modulating the flame)
to respond to the amount of water extracted.
This device is equipped with an electronic tool that is powered by
a 1.5 V battery that automatically switches on the pilot flame and
then the burner every time that hot water is extracted.
The flame is switched on using a card that ionizes the flame
Lipari Tn 11i: for the extraction of 2,5 to 5 l/min the temperature
of the water supplied remains at 60°C, (in this case the has valve
supplies the burner with the necessary quantity of gas proportional
to the water supplied), above 5 l/min to 11 l/min the water tempera-
ture varies from 60°C to 40°C.
Lipari Tn 14i: for the extraction of 2,5 to 7 l/min the temperature
of the water supplied remains at 60°C, (in this case the has valve
supplies the burner with the necessary quantity of gas proportional
to the water supplied), above 7 l/min to 14 l/min the water tempera-
ture 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 immedia-
tely before the water heater on the gas input pipe
- Rotate knob A towards the large flame (ON
when the small flame is reached it is necessary to press lightly
while turning until it reaches its destination.
- When hot water is requested, the device automatically turns on
the pilot flame, this lights the main burner.
- When the hot water request has terminated (turning the water
tap off) the burner automatically switches off, the device then
awaits another heating request.
If after 60 seconds it does not switch on, the flame detector inter-
rupts the flow of gas and blocks the device.
To reuse the device after it has been blocked, close the hot water
extraction tap and then reopen it to restart the sequence.
A
If the main burner accidentally switches off, the device will attempt
to turn it on again.
If within 60 seconds the device does not function it is blocked.
The device is built to function with normal water pressure; in addi-
tion a temperature selector B is also supplied.
Rotate the knob completely to the left to obtain the maximum water
output or completely to the right for the minimum water output.
The machine is switched off by rotating knob A to the ( OFF) po-
sition.
When the water heater is not used for long periods close the gas
supply tap or the LPG gas valve on the tank.
For the best operational results it is recommended to have a quali-
fied technician service the machine at least once a year.
Gas economizer
The device is equipped with a gas economizing device which is
used to choose the temperature of the water so it may be supplied
at the temperature necessary while saving gas.
The economizing device is activated by turning the knob A until it
reaches the picture of the small flame (MIN
mizer limits the amount of heating when the hot water usage is mo-
dest (water supplied is already warm or there is a reduced usage,
for example in summer).
DANGER OF FREEZING
If there is a possibility that the area where the device is stalled
could reach below 0°C, the device must be emptied of all water
contained.
