How to Install an Oil Heater

Choose a location indoors for the heater. It must be along the inside of an exterior wall that no foliage or other flammable objects on the outside. Be sure that there are no electrical lines or plumbing in the exterior wall behind the heater. There must be sufficient distance between the heater an all flammable objects so that no walls, curtains, furniture or other materials are affected by the heater. There must also be a wall outlet within reach of the heater's electrical cord. Don't use an extension cord.

Drill a hole for the flue pipe. Locate the center of the joint pipe opening and drill a corresponding hole through the outside wall so that the straight flue pipe can pass directly from the joint pipe through the hole. Use a drill bit that is the same size as the flue pipe, typically less than 2 inches. If your exterior wall is masonry, use a masonry bit and an impact driver. After drilling through just the drywall, look and visually confirm that there are no impediments, such as studs or gas lines, to finishing the hole and installing the flue pipe. Drilling through insulation is not a problem. If there are impediments, move the heater. Pass the flue pipe through the hole, and fasten it to the joint pipe.

Install a lifter pump to provide fuel for the oil heater. The lifter pump must be installed on a wall above the heater and inside the home. It can be in the same room as the heater, or on another floor. Connected the fuel tank to the lifter pump and the lifter pump to the heater with approved copper pipes. Be sure the fuel tank is equipped with a shutoff valve and a fuel filter, which will be labeled and fitted at the outflow spout of the tank.
