Control Of The Gas Inlet Pressure; Control Of Primary Air Flow; Control Of Pilot Burner - OFFCAR 700 Serie Manual De Instrucciones

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 ").
− Before connecting the manometer, the screw of the pressure port must be loosened.
− Connect the U-shaped pressure gauge while the appliance is operating to measure
pressure.
− The pressure reading on the gauge should be in the admitted pressure range stated in
table 6b "Inlet pressures" of paragraph "Technical data".
− If pressure figures should not be correct, apply to the gas board or the company which
has installed the system.
− Having read the pressure, re-tighten the screw carefully.
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 3.
- 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 3).
