NOTE: ALL GAS FITTING MUST ONLY BE CARRIED OUT BY A QUALIFIED PERSON.
1.
This appliances do not require an electrical connection, as they function totally on the gas supply only.
2.
It is essential that the gas supply is correct for the appliance to be installed and that adequate supply
pressure and volume are available. The following checks should therefore be made before installation:-
a. Gas Type the appliance has been supplied for is shown in the rating label. Check that this is correct for the
gas supply the appliance is being installed for. The gas conversion procedure is detailed in this manual.
b. Supply Pressure required for this appliance is shown above table 1. Check the gas supply to ensure adequate
supply pressure exists.
c. The appliance should be connected to the gas supply by means of metal pipes --either rigid or flexible-- having
an adequate diameter. When joining pipe fittings, never use oakum or Teflon as their residues could get to the valve
and jeopardize its operation. Instead, interpose a seal gasket suitable for use in gas systems.
WARNING:
DO NOT USE A NAKED FLAME TO CHECK FOR GAS LEAKAGES.
4.11 Checking gas supply pressure after installation
Gas supply pressure may be measured using a liquid or a digital manometer.
Proceed as follows:
1)
Remove the control panel;
2)
Connect the manometer;
3)
Start up the appliance by following the information in "Operating instructions";
4)
Check supply pressure;
5)
Remove the manometer;
6)
Refit the screw and check for leaks.
If the measured pressure valve is within the range shown in
."Table 1: Gas categories and pressures"
, the appliance
can be turned on; otherwise, contact your Gas Company.
4.12 Gas technical specifications
The appliance should be started up at its rated output with the nozzles shown in
"Table 2: burner specifications"
below. All the necessary nozzles are provided in a small bag together with the appliance. The nozzles of the main
burners are marked in hundredths of mm, while those of pilot flames have a reference number.
4.13 Checking operation
1. Start up the appliance by following the instructions given in chapter
"Using the appliance"
;
2. check for gas leaks;
3. check for flame stability throughout the whole control range by going from high to low.
