527 CMR 4:00 Oil Burner Equipment (26-50)- Questions
and Answers
Fuel Oil Correct Ans-Any oil as specified by the American Society for Testing and Materials
(ASTM) standard D396-90, Standard Specification for Fuel Oils; or ASTM D6751-02, Standard
Specification of Biodiesel Fuel (B100) Blend Stock for Distillate Fuels.
Furnace, Central Warm-Air Correct Ans-A self-contained indirect-fired or electrically
heated appliance designed to supply heated air through ducts to spaces remote from or
adjacent to the appliance location
Gravity-type Central Furnac Correct Ans-A central furnace depending primarily on
circulation of air by gravity.
Gravity-type Central Furnace with Integral Fan Correct Ans-A central furnace equipped
with a fan as an integral part of its construction and operable on gravity systems only. The fan
is used only to overcome the internal resistance to air flow.
Gravity-type Central Furnace with Booster Fan Correct Ans-A central furnace equipped
with a booster fan that does not materially restrict free circulation of air by gravity flow when
such a fan is not in operation
Forced-Air-type Central Furnace. Correct Ans-A central furnace equipped with a fan that
provides the primary means for circulation of air
Horizontal-type Central Furnace Correct Ans-A furnace designed with air flow through the
furnace essentially in a horizontal path.
Upflow-type Central Furnace Correct Ans-A furnace designed with air flow essentially in a
vertical path, discharging air at or near the top of the furnace.
