READ THIS FIRST!
Failure to adhere to the guidelines below can result in severe personal injury, death or substantial property damage.
Service and maintenance –
1.
To avoid electric shock, disconnect electrical supply before
performing maintenance.
2.
To avoid severe burns, allow furnace to cool before performing
maintenance.
3.
Perform service and maintenance as described in this manual
and the burner manual.
4.
Do not attempt to make adjustments to the blower or motor while
the furnace is in operation. Disconnect power to the furnace and
be sure all parts have stopped moving before attempting
adjustments or maintenance.
5.
The burner must be set up and adjusted using combustion test
instruments. Visual examination of the flame alone cannot
determine combustion performance.
Operation -
6.
Do not use the furnace as a construction heater.
7.
Do not operate any furnace if the heat exchanger is damaged,
corroded or pitted. Toxic flue products could enter the air stream.
8.
Do not jumper, attempt to by-pass or override any limit control.
9.
Do not block flow of combustion or ventilation air to furnace. Do
not block or obstruct the air openings in the furnace casing.
10.
Do not store or use combustible materials, gasoline, or other
flammable liquids or vapors in the furnace area.
11.
Do not operate the furnace if the furnace area will be exposed to
air contaminants as described on page 5.
12.
Should overheating occur, do not turn off or disconnect electrical
supply to furnace. Instead, shut off the oil supply at a location
external to the appliance, if possible.
13.
Do not use this furnace if any part has been under water. Call a
qualified service technician immediately, to inspect the furnace
and to replace any part of the furnace, control system or burner
that was submerged in water.
14.
Do not operate furnace if temperature rise through heat
exchanger exceeds 85
o
F.
15.
Inspect, clean and replace (if necessary) return air filter regularly.
16.
Do not obstruct return air grills or supply air outlets.
17.
Supply only #2 fuel oil to the burner. Never attempt to use gasoline,
a mixture of gasoline and oil, waste fuel, refuse or any other
substance in the burner of furnace.
Installation -
18.
Do not block flow of combustion or ventilation air to furnace. Do
not block or obstruct the air openings in the furnace casing.
19.
Connect furnace only to a functional vent system in good
condition. Place the furnace to allow proper venting, with the
shortest possible venting and minimum number or elbows.
20.
Always connect and seal a return air duct to the furnace unless
the furnace is located in a large space, such as an unpartitioned
basement. Route the return air duct to an adjacent room if no
return air manifold is used.
21.
Install furnace maintaining minimum clearances for service and
separation from combustible surfaces described in this manual.
22.
Install, start-up, service and maintain burner per instructions in
this manual and the burner manual.
23.
Verify burner is properly inserted through the combustion
chamber opening.
24.
Furnace must be installed so that burner and control system
components are protected from dripping, spraying water or rain
during operation or service.
25.
If installing an air conditioning evaporator coil, install the coil
downstream of, or in parallel with, the furnace to prevent
condensation on the furnace heat exchanger. If the coil is in
parallel, provide means to prevent flow of chilled air into the
furnace, including an interlock to prevent simultaneous operation
of heating and air conditioning.
Apply the following suggestions to prevent unsatisfactory operation of the furnace.
Installation –
1.
Be sure to level the furnace, using a spirit level at the front and
one side. If the furnace is not level, oil can drip into the
combustion chamber after burner cycling and contaminate the
heat exchanger and the burner head.
2.
Make sure all legs are in contact with the floor to distribute the
load and prevent the possibility of undue noise or vibration.
3.
Avoid locating return grills in rooms that may contain undesirable
odors.
4.
Never locate a return air grill closer than approximately 20 feet
from the furnace.
5.
Locate the furnace near the center of the supply and return duct
systems.
6.
Always check the size of the ducts on a replacement installation,
particularly if adding air conditioning.
