METHOD FOR OPERATING GAS BOILER ACCORDING TO LOWERING OF GAS PRESSURE

摘要

PURPOSE: A method for operating gas boiler according to lowering of gas pressure is provided to control air amount by downwardly adjusting temperature set by a user, thereby removing air frictional sound. CONSTITUTION: A method for operating gas boiler according to lowering of gas pressure includes the steps of starting operation of a system in a gas boiler(S2), performing normal combustion operation by sensing the temperature of heating collecting water side and heating tapping side(S4), sensing lowering of gas pressure during the normal combustion(S6), downwardly adjusting temperature set by a user if the lowering of gas pressure is sensed(S8), confirming the downward adjustment of the temperature set by a user by sensing the temperature of the heating tapping water(S10), and performing normal combustion by maintaining the state until air frictional sound is not generated if the confirmation of the downward adjustment is completed(S12).
