Gas Heater Repair

Friends who read this part, please read the above: Principle of umbrella-shaped gas heater, principle of cabinet-type gas heater. Because the protective devices of umbrella-shaped heater and cabinet-type heater are roughly the same, here we combine umbrella-shaped heater and cabinet-type heater. The maintenance of heater is basically the maintenance of protective device. Let's first know the accessories that make up the protective device: thermal sensing needle (ie thermocouple), solenoid valve, tipping protection device, Fault phenomenon: 1. When the heater is ignited for 3 seconds and then released under normal burning conditions, the heater will immediately go out. Cause of failure: This fault is mostly caused by a broken thermocouple, which can be replaced. After replacement, the fault still exists, replace the solenoid valve. If the new machine is extinguished when released, it is mostly caused by the excessive pressure of liquefied gas, and the flame sprays too long to burn the thermocouple sensing needle. Just adjust the pressure of the pressure reducing valve appropriately. 2. The heater goes out naturally for no reason when burning normally. Cause of failure: The inferior heater uses an unqualified tipping protection device, so replace the tipping protection device with a good quality one. Also, check whether the fuel in the liquefied gas cylinder is used up. 3. The flame is huge or very small after ignition. Cause of the fault: The pressure reducing valve is broken, replace the pressure reducing valve. 4. Other faults, such as the simple problem of not being able to ignite the heater due to the liquefied gas cylinder switch not being turned on, the liquefied gas cylinder fuel being used up, the control knob not being adjusted to the open position, etc., I believe that the instructions of each brand of heater will explain in detail, so I will not repeat them here.
