Checking The Air And Gas Pressure On The Combustion Head; Safety Components - Riello RS 200/E FGR Installation, Use And Maintenance Instructions

Clean UV sensor
Periodically clean the bulb to ensure correct operation of the UV
sensor.
Gas leaks
Make sure that there are no gas leaks on the pipes between the
gas meter and the burner.
Gas filter
Replace the gas filter when it is dirty.
Flame inspection window
Clean the glass of the flame inspection window.
Boiler
Clean the boiler as indicated in its accompanying instructions in
order to maintain all the original combustion characteristics intact,
especially the flue gas temperature and combustion chamber
pressure.
Combustion
If the combustion values found at the start of the intervention do
not satisfy current standards or anyway indicate a poor state of
combustion (consult the table below), contact the Technical As-
sistance Service for the necessary adjustments.

7.2.4 Checking the air and gas pressure on the
combustion head
To carry out this operation a pressure gauge must be used to
measure the air and gas pressure at the combustion head, as
shown in Fig. 37.
