INITIAL OPERATION OF THE FURNACE
Initial Burner Operation
c WARNING: To avoid possible explosion, DO NOT attempt to light the burner if:
• Oil has accumulated in the base of the combustion chamber.
• The furnace is full of fuel vapors.
• The combustion chamber is very hot.
c CAUTION: The oil burner must be installed and adjusted using recently (within
the last year) calibrated combustion instruments by a qualified heating contractor
prior to placing the furnace in operation. Refer to this manual and the oil burner
instruction manual for details.
c CAUTION:
• To minimize initial fuel oil and combustion odors, ventilate the building
well while operating the furnace for the first time.
• Do not run the oil pump dry (without oil) for more than two (2) minutes.
Damage to the oil pump may result.
To initially operate the furnace:
1) Turn the electrical disconnecting switch to the “OFF” position.
2) Set the room thermostat above room temperature.
3) Be sure the oil tank is full of clean # 2 fuel oil.
4) Open all shutoff valves in the oil line.
5) Turn on the electrical disconnecting switch and prime the burner oil pump
according to the pump manufacturer’s instructions.
6) When ignition is established, make a temporary air adjustment for a clean,
smoke-free flame. At this point, the final burner adjustment should be made
using test instruments to measure oil pump pressure, smoke number, carbon
dioxide (CO
2
), carbon monoxide (CO), draft, and flue gas temperature.
• Refer to item (4) under the Troubleshooting section of this manual for a list
of required test instruments.
In order to achieve the best combustion efficiency, the following procedure is
recommended.
