A Home's Oil Furnace The Series Windsor County Vermont Home Buyers Accompany Series Post 3, this post and two others to follow are accompaning posts to my second series of a challenge to write blog post series. The title to the series is A Home's Oil Furnace The Series Windsor County Vermont Home Buyers. These seriers are to help Home Buyers, Home Owners, and Real Estate Agents, to understand Oil Furnaces. Feel free to pull up a chair, and enjoy reading and learning.
A conversion type oil burner can be adapted to most forced warm-air furnaces. There are areas in the Country, that do not have natural gas available, like here in Vermont and New Hampshire, a oil burnering furnace is the next best heating source. The operating cost is midway between natural gas and electric residential heating.
An oil burner requires a combustion chamber to contain the flame. This chamber is fourteen inches to eighteen inches in diameter and can be made of stainless steel or insulating firebrick. The stainless steel chamber of the furnace, is sized to match the firing rate in gallons per hour. Some firebrick chambers are preformed to size, while some others are built on site to fit the available space in the home.
A Home's Oil Furnace The Series Windsor County Vermont Home Buyers Accompany Series Post 3, the information you'll need to purchase an oil burner can be found on the nameplate of the furnace. The nameplate has the BTU input and output, such as, 85,00 BTU. 100,000 BTU input. The BTU input determines the firing rate in gallons per hour. The standard domestic oil burner uses No. 2 fuel oil. which contains 136,000 BTU per gallon heat value. Most single homes of up to 1,800 square feet floor area would have a 150,000 BTU furnace firsed at a rate of 1.10 GPH, Smaller homes might need a firing rate of 0.70 or 0.85 GPH.
If your installing a new oil burner, you'll want to have the combustion chamber inspected and replace it, if needed. You'll want to measure the present chamber for correct size replacement. The furnace manufacturer's local dealer should have all of the necessary parts on hand, or they can order the items for you. In addition, you'll need furnace cement, bolts, 3/8 inch copper tubing, 3/8 inch flare fittings and flare nuts, a short piece of flexible metal conduit, necessary fittings, and wire connectors. A new stack safety relay or other safety control might be included with the new burner. The fan and limit controls can still be used, if they are in good operating condition.

If the wiring of the furnace is in good condition, it can be reused. But do replace the flue pipe and vacuum, and brush the passages inside the furnace. You'll want to determine the nozzle firing rate and angle of spray, and whether it is a solid or hollow spray. Theres a designation stamped on the nozzle such as, 0.85-80-H, this means a 0.85 gallons per hour oil flow, 80 degree spray angle, and H, hollow or S, solid. The hollow spray is similar to a funnel, with the funnel wall the oil droplets. A solid spray is still the cone shape, but the cone is solid with oil droplets. The design of the replacement burner might be slightly changed, making minor adjustments necessary.
If you are not familiar with a oil burners operations and start up, it sure would be wise to have the burer started and adjusted by a service technician. There are necessary tests that must be made, for which specialized instruments are needed, and its worth the cost of the service call to have the start up done right.
