DESCRIPTION
This is a high end product line for those in the dedicated oil
business or HVAC contractor who demands the best in an oil
furnace. These oil-fired furnaces are decorator-styled warm
air heating units designed for installation in basements, clos-
ets, recreation rooms or garages. The complete line consists
of three types of furnaces with 9 available models. Heating
capacities range from 58 through 188 MBH bonnet output.
All models are designed to accommodate add-on air condi-
tioning. The capacities, cfm's and performance are matched
to meet year-round comfort requirements. After the installa-
tion of an oil-fired furnace, the air conditioner may be added
at any time by adding a compact cooling coil to the furnace,
and a small quiet condensing section outside the home.
