FAQ burner

1 motor is running, the ignition is normal, but later downtime
(1) The magnet valve is not open, because the solenoid valve coil failures or cable breaks (1) replace the solenoid valve or exclude circuit unreasonable failure
(2) Disconnect the ground line (2) to re-examine the ground is intact
2, the device has a tightness test apparatus, the burner motor running, the ignition is normal, but later stop (no fault display)
(1) The solenoid valve does not seal (1) exclude the seal case
(2) insufficient supply (2) to improve gas flow
(3) filters (3) Clean or replace
3, the burner motor running, the flame is formed normally, but then downtime
(1) ionization current instability, is too low (1) to change the position of the flame ionization electrode plate and check the connection line
(2) gas air mixture adjustment unevenness (2) to re-adjust the gas air mixture
(3) spark ignition affects the ionization current (3) ignition transformer primary winding replace the phase and neutral

Gas burners safety valve how to care?

Gas Burner Safety Valve is boiler to protect the last line of defense, in the boiler pressure exceeds the limit, according to the valve design with a set pressure, exhaust pressure relief, to ensure the normal operation of the boiler.
1. To keep clean safety valve to prevent the valve spring stalks, etc. are full of dirt or corrosion grease to prevent the gas valve discharge pipe is clogged oil or other foreign matter; always check seal is intact, preventing the lever-type safety valve hammer loose or moved, preventing the spring-loaded safety valve adjustment screw is free to twist.
2. After cleaning the safety valve must be re-commissioning.
3. The valve should be used to clean light oil.
4. After the beginning of the operational phase of commissioning, should be carefully observed the operation of the safety valve.
5. Safety valve leaks found signs should be replaced or maintenance. Prohibit the use of increased load (eg adjusting screw on the lever or safety valve lever and hang heavy loads over tighten the spring-loaded safety valve) is the way to eliminate leakage.
6. Periodically check the operation of the safety valve leaks, appropriate measures to jamming and spring corrosion and other irregularities, and to observe the adjustment nut and adjusting ring set screw lock nut is loose, if a problem should take timely .
7. The safety valve is installed outdoors should take appropriate protective measures to prevent the rain and fog, dust, rust and other dirt pollution and invasive valve discharge pipe, when the environment is below zero degrees Celsius, freezing should take the necessary measures to ensure safety valve reliability.
