Check furnace location
Pre-installation checklist
Verify code compliance
Local, state, provincial, and national codes, laws, regulations
and ordinances
NFPA-31, Installation of Oil-Burning Equipment
National Electrical Code
All local codes and/or regulations take precedence over the
instructions in this manual and should be followed accordingly.
TMP furnaces, their burners and controls met safe
lighting and other performance criteria when furnace
underwent tests specified in Underwriters Laboratories
Standard UL727.
Check location and furnace specifications
Use the table below to verify:
Furnace heating capacity
Space is large enough to provide required clearances
Verify the installation will meet the requirements of this manual:
Clearances (page 3)
Combustion/ventilation air openings (pages 4)
Supply air duct (page 8)
Vent system (page 11)
Fuel oil piping (page 12 plus burner manual)
Electrical connection (page 14)
Clearances
Minimum clearance to combustible materials
1. Install the furnace, ductwork and vent such that no combustible
surface is closer than listed in Table 1.
Flue pipe clearances must take precedence over
jacket clearances (listed below).
Service accessibility clearances
1. Provide no less than the minimum clearances given in Table 1 to
ensure the furnace can be properly operated, serviced and
maintained.

2. Always apply whichever clearance is LARGER – combustible
construction or service accessibility.
Flooring and foundation
Flooring
TMP furnaces are approved for installation on non-combustible floor.
If a combustible floor is used, follow these instructions:
Horizontal installation on combustible floor
Always keep the minimum installation clearances of 1 inch between
the combustible floor and the furnace sides. Use appropriate leveling
legs or optional kit #HFB-1-W.
Counterflow installation on combustible floor
Always keep the minimum installation clearances of 1 inch between
the combustible floor and the furnace bottom or air supply plenum.
Use appropriate leveling base and spacers or optional kit #CFB-
1-W.
Do not install furnace on carpeting even if foundation
is used. Fire can result, causing severe personal
injury, death or substantial property damage.
Foundation
1. Provide a solid brick or minimum 2-inch thick concrete
foundation pad if any of the following is true:
•
the floor can become flooded.
•
the furnace mounting area is not level.
Residential garage installations
Take the following special precautions when installing the furnace in
a residential garage. If the furnace is located in a residential garage:
•
Mount the furnace a minimum of 18 inches above the floor
of the garage.
•
Locate or protect the furnace so it cannot be damaged by a
moving vehicle.
