This assembly ensures that gas is ignited safely and that exhaust gases are vented correctly through the blower system. If your water heater won?t ignite, struggles to maintain temperature, or the blower fails to operate, replacing the combustion assembly may resolve the problem. Over time, wear on the burner or blower motor can cause ignition failures or poor heating performance. Installation requires safely disconnecting gas and electrical connections. Always turn off the gas supply and unplug the water heater before starting this repair. Wear work gloves to protect your hands when handling the assembly. | Rheem Complete Combustion Assembly SP21001B Genuine OEM
