apg gas heaters works

The basic principle of gas indoor heaters is cold water enters the heater, air flows through the water at a certain pressure valve linkage difference between the role of the flow of water, promote water-gas linkage valves, and a DC power supply while promoting micro switch will power on and start the Pulse ignition, at the same time open the gas gas solenoid valve, pulse igniter continue automatic ignition again until successful ignition into normal working condition so far, this process is about continuously for 5 to 10 seconds, when a apg gas heaters in the course of their work or ignition process water shortages or lack of water pressure, lack of electricity, lack of gas, hot water temperature is too high, unexpected blow when flameout and other symptoms, pulse igniter feedback signal by detecting the sensor needle, automatically cut off power, gas gas solenoid valve the case of shortage of supply immediately respond to a normally closed valve original state, that time has been cut off the gas passage, shut off the gas heater play a security role. Typically a qualified apg gas heaters, refers to the performance indicators in line with GB6932-2001 "Domestic gas instantaneous water heater" apg gas heaters national standards from the ignition state to enter the normal operating state of the entire process is fully automated control, without human adjustment or Additional settings, simply open the cold water switch or turn cold water, adjusting means and the air conditioner to get the right amount of water and the water temperature by adjusting the amount of water, apg gas heaters immediately within 5 to 10 seconds in a short time into the normal working state, while production out of hot water, once more unexpected failure,apg gas heater will automatically stop working within 10 seconds, and immediately cut off the gas passage to prevent the gas continues to flow, and can not be automatically re-opened, unless artificially clear the fault and restart Gas food, in order to work state, so its performance is more safe and reliable.
