2.Boiler Fire off Protection :

If oil gas boiler fire off,if continue to supply fuel, the furnace may explode.This oil(gas) boiler burner equip with flam detection device,it can inspect the the furnace combustion condition.if gnition is failure or flamout halfway,it will close the oil(gas) solenoid vave in 5seconds(ignition),close the solenoid valve in 10 seconds(operation),and will Send out sound and light alarm signal. At this time,the forced draft fan continue working to blow off the flammable gas, after 20-30 seconds, the forced draft fan will stop working and all auxiliaries will power off automatically.
