INSTALLATION INSTRUCTIONS
(Continued)
GAS SUPPLY & CONNECTION
Check that the gas supply corresponds to that specified on the data plate.
Connection is via a 1/2" bspt male thread on the back of the unit. If connection to the supply pipe is via a
flexible hose, ensure that the hose used is suitable for commercial catering appliances.
Check that the gas supply pipeline has sufficient volume for the appliances/s to be connected to it.
WARNING: Black domestic hoses are not suitable for this appliance.
When making the connection onto the appliance, secure the hexagon on the fitting to prevent rotation of the
internal pipe work. An isolating cock should be fitted into the supply line to the appliance for servicing
purposes.
PRESSURE SETTING
For Natural gas appliance only, fit the pressure governor supplied onto the inlet pipe-work after the isolating
cock. Remove the control panel and fit the pressure gauge to the test nipple situated on the left hand end of
the manifold. With the oven burner lit only and burning at full rate, adjust the burner pressure to:
17.5mbar for Natural gas
The supply pressure for Natural gas appliances are 20mbar and for LPG (Propane) appliances, 37mbar and
for Butane 30mbar nominal.
OVEN LOW FLAME SETTING
Check the low flame setting by lighting the oven and heating to a set temperature. When the set temperature
has been reached the thermostat will reduce the oven burner flame to its low rate. Check that rapid closing of
the oven door does not extinguish the flame. If necessary, adjustment to the low flame setting is made by
removing the oven knob and turning the bypass adjustment screw (Clockwise to decrease and anti-clockwise
to increase the flame). Care should be taken, as the appliance will become hot during commissioning.
Note: To obtain the above burner pressures adjust the regulator as supplied with the unit. When the correct
operating pressure has been obtained then re-assemble unit.
WARNING: Failure to check and set the oven low flame setting may initiate an un-necessary service
call due to the oven burner "going out".
