Pipe For Gas Connection; Checking Heat Output; Connection For Liquid Gas G30/G31; Connection With Methane Gas H G20 - Lotus BRF-94G Guia Para La Intalación E Instrucciones De Uso

The gas connection must be effected with steel or copper pipes, or otherwise with flexible steel pipes in compliance
with the national norms, if any exist. Each appliance must be provided with a cut-off cock for rapid interruption of the
gas supply. Once the appliance has been installed, it is necessary to check for gas leaks for the pipe fittings; do not use a
flame for this purpose but a non-corrosive substance such as soapy water or phoamy substances as contained in leak-
finder sprays. All our appliances undergo careful testing: the type of gas, the operating pressure and the category are
indicated on the data plate.
The appliances must be checked in such a way as to verify that the heat output is correct:
• The heat output (thermal power) is indicated on the data plate of the appliance.
• Firstly, check that the appliance can be used with the type of gas supplied; then check that the indication on the
plate corresponds to the gas to be used. For converting to another type of gas, check that the type of gas complies
with what is stated in this instruction manual.
The pressure must be read by inserting a gauge for liquids (e.g. a U gauge). With a minimum definition of 0,1
mbar, into the relative pressure outlet (see fig. B position C).
Remove the screw from the airtight pressure outlet, connect the rubber pipe of the U gauge and read the
pressure.
After reading, remove the flexible pipe of the gauge, put back the screw, tighten hermetically and check the pressure
tightness.

Connection for liquid gas G30/G31

The connection pressure for liquid gas is 30 mbar with butane and 37 mbar with propane.
Check the plate, read the pressure and verify that the description of the nozzle installed corresponds to the one supplied
by the manufacturer.

Connection with methane gas H G20

The connection pressure for methane gas is 20 mbar.
Check the plate, read the pressure and verify that the description of the nozzle installed corresponds to the one supplied
by the manufacturer.

CHECKING PRIMARY AIR TO THE MAIN BURNERS AND PILOT NOZZLES

All the burners are fitted with an air regulator by means of which the primary air can be varied thanks to an adjustable
bush that can be locked with a screw. In the "Burner Technical Data" table you will find the approximate values for the
"h" parameter (primary air). The flow of primary air must be regulated so there is no detachment of the flame when the
burner is cold or a return of the flame when the burner is hot.
The pilot air is regulated when the appliance is tested and inspected for the gas it is set for.
If you are going to change to a different type of gas, regulate the air by means of the adjusting bush until the flame stops
sputtering and becomes an intense blue colour.
