How to replace a General 1A-25A Fuel Oil Filter Element
The General 1A-25A Fuel Oil Filter is a common filter used in residential homes with oil-burning heating and water heating appliances. It is relatively easy to replace and can help to prevent sludge, debris and water from clogging your oil burner nozzle.
To replace a General 1A-25A Fuel Oil Filter Element, first locate the oil burner service switch and turn it off. Then, close the valve to stop the oil from flowing to the filter and prevent excessive spillage. Place a catch pan under the filter to catch any spillage.
Loosen the centre bolt on the top of the filter, which secures the filter canister in place. Bang the centre bolt sharply with a wrench to loosen the canister. Invert the canister and the old element into the catch pan, and dump out the oil and old element. Make sure the gasket is removed from the canister and has come completely off the top housing. Remove the centre screw and vent screw and take the washers off them.
Open the box with the new filter parts and put the new washers from that box on the centre bolt and vent screw. Place the new filter element in the canister and moisten the rubber gasket for the canister with a thin film of oil, then push it into place. Lift the canister and new element into place, hand tighten the centre screw, and make sure the gasket is seated properly then tighten the centre screw.
You will need a good quality adjustable wrench or a wrench set, something to catch spilling oil with such as an old metal baking pan, some rags, and a flashlight. You will also need to buy a new replacement element with the General part number # 1A-30, which is a 10-micron wool felt element.

How to locate the oil burner service switch
The General 1A-25A Fuel Oil Filter is a common filter used in residential homes with oil-burning heating and water heating appliances. It is relatively easy to replace and can be done by the user. To replace the filter, you will need a good quality adjustable wrench or a wrench set, something to catch spilling oil, some rags, and a flashlight.
The General 1A-25B Fuel Oil Filter is also available as a replacement cartridge. It is the exact same as the 1A25A, but now sold with biofuel-compatible gaskets.
To locate the oil burner service switch, you must first turn off the oil burner service switch and the valve that will stop the oil from flowing to the filter. This will allow you to change the element without excessive spillage. The valves used are unique because the valve is a fused valve, which in the event of a fire is designed to melt and close on its own. You will find that the knob unscrews then the stem of the valve snaps closed.
For electrically powered appliances, there should be an identified switch in the burner circuit, placed near the entrance to the room where the appliance is located. If the appliance is located in a cellar or basement, the switch must be located at the top of the stairs leading to the basement. If the boiler room door is on the building's exterior, the switch should be located just inside the door. If there is more than one door to the boiler room, there should be a switch located at each door. The switch should be marked for easy identification and consideration should be given to the type and location of the switch to safeguard against tampering.
