GAS PRESSURE SETTINGS
To regulate the gas inlet pressure :
• Connect a manometer to pressure test point (PM)
• Ensure that gas supply pressure is sufficient as detailed the table in the manual provided :
To regulate the head pressure at the injectors:
• Connect a manometer to pressure test point (PV)
• Adjust the pressure untill it is correct to the data supplied in the following table:

ERSION TWO STAGE
Propane Gas (G31)
TYPE 1 2 3 4 5 6
Gas inlet pressure 37 mBar
Head pressure max 35,0 35,5 35,5 34,5 35,5 34,5 mBar
Head pressure min (two stage)

Warning gas inlet pressure should not exceed 60 mBar.
SINGLE STAGE
Gas valve regulatiion Propane G31:
For operation with propane G31 the pressure regulation
screw on the valve must be excluded.
To exclude the regulation screw on the gas valve
the following proceedure should be carried out:
• Remove the plastic cap
• Turn the screw RP clockwise to the bottom
• Replace the plastic cap and reseal with paint
For heaters equiped with two gas valves it will be necessary to exclude both valves .
TWO STAGE
Gas valve regulation Propane G31 :
Gas valve head pressure setting high fire Propane G31:
When setting the gas pressure for propane high fire
(second stage ) contact SF should be closed the high
fire pressure adjusting screw on the gas valve must be
excluded.
Connect a manometer on test point PV
Remove the plastic cover from the adjuster RP1 RP2
With a screw driver hold the adjuster RP1 stationary
and using a spanner, screw adjuster RP2 clockwise to
the bottom of the thread until the correct pressure
according to the data plate is achieved .
