Control Of The Gas Inlet Pressure; Control Of Primary Air Flow; Control Of Pilot Burner - Firex 900 Serie Manuel D'installation, D'entretien Et D'emploi

2.3.1. CONTROL OF THE GAS INLET PRESSURE

- The feed pressure is measured using a liquid pressure gauge ( e.g. a U-shaped
pressure gauge, minimum definition 0.1 mbar). The supply pressure can be measured
directly at the inlet pressure intake on the gas feed pipe. The inlet pressure intake can
be reached by opening the lower front panel once the two side screws have been
removed. (See figure "Measuring the inlet pressure ").
- Unloose or remove the pressure intake screw
- Connect the U shaped pressure gauge
- Start the appliance according to instructions
- Measure the inlet pressure
- Disconnect the U shaped pressure gauge
- Tighten the seal screw
Warning! The sealed adjuster screws on the gas solenoid valve must not be
tampered with, otherwise any guarantee rights shall be forfeited
immediately.

2.3.2. CONTROL OF PRIMARY AIR FLOW

- Primary air can be considered correctly adjusted if no flame lift is ensured when the
burner is cold and the injector lights when the burner is hot.
- The distance recommended for primary air regulation is indicated in table 4.

2.3.3. CONTROL OF PILOT BURNER

- Start the pilot burner according to instructions. If the pilot is adjusted correctly, the
ignition flame will contact the thermocouple evenly and the flame will have a perfect
appearance. Otherwise it is necessary to check if the correct injectors have been
installed (see table 4).
