INSTALLATION and OPERATING INSTRUCTIONS
EQUIPMENT SELECTION
An accurate heating load calculation must be conducted
using American Society of Heating, Refrigeration and
Air Conditioning Engineers (ASHRAE) or Air
Conditioning Contractors of America (ACCA) manuals.
Do not add a large safety factor above the calculated
value. If the calculated heating load requirement
exceeds the heating capacity rating of a given model,
use only the next larger size available. Never increase
by any more than absolutely necessary based upon
available equipment heating capacities. Always select
based upon heat capacity (output), never use input
capacities.
NOTE: It is the personal responsibility and
obligation of the purchaser to contract a
qualified installer to assure that installation
is adequate and is in conformance with
governing codes and ordinances.
LOCATING THE FURNACE
When installing the furnace be sure to provide adequate
space for easy service and maintenance. Locate the
furnace as close to the chimney as practical, giving
consideration to the accessibility of the oil burner,
controls, and blower for service. Allow a minimum of
24 inches at front of furnace for servicing oil burner.
Allow adequate room for filter and blower
maintenance. Clearance from combustible material as
stated on the furnace and repeated in Table 1 must be
maintained. For damp basement installations, a raised
concrete pad is recommended. This will help keep the
bottom of the furnace dry and reduce the risk of rusting.
An oil burner must have a generous supply of
combustion air to operate properly. The flow of
combustion and ventilating air must not be obstructed
from reaching the furnace. See “Combustion Air
Requirements” section.
The furnace area must be kept clear and free of
combustible materials, gasoline and other flammable
vapors and liquids.
This unit is not designed for mobile home or trailer
installations. Always install furnace in a level position.

For the first three (3) feet from plenum. After three (3) feet, no clearance required.
