Gas boom installed when the issue of "creak" sound, I do not know what is the fault? After the start is normal!
Gas furnace is easy to produce noise parts and reasons: 1, fan fan is driven by the motor device, long-term use after the lack of maintenance (dust, plus lubricants, etc.) prone to friction and noise. 2, pump water pump is the heating power of the cycle of power devices, but also a motor device, prone to noise.
You can listen carefully, is not what place caused by vibration
It should be the sound of boiler ignition. You can try to turn off the gas valve to let the boiler fire, see will not appear three times this sound, if there are three times, then your boiler is normal, but after the fire you want to re-under the boiler
May be the sound of the exhaust fan! The When the fireplace starts the first start is the fan!
