Carrier 58BTA, 58BLA, 58BMA manual Here are a FEW DO’S and do NOT’S, Combustion AIR Requirements

!WARNING

The unit cabinet must have an uninterrupted or unbroken electrical ground to minimize personal injury if an electrical fault should occur. This may consist of electrical wire or approved conduit when installed in accor- dance with existing electrical codes. Do not use oil piping as an electrical ground. Fail- ure to follow this warning could result in an electrical shock, fire, or bodily harm.

1.Excessive oil burner after drip and oil fumes.

2.Sooting.

3.Melted oil burner couplings and/or ignitor/relay control.

4.A condition where air band or air shutter settings must be more open than normal to achieve proper combustion.

5.Lockouts on start-up.

!WARNING

Return air must not be taken from the room in which the appliance is installed. All duct connections to the furnace must be airtight to avoid a “negative” pressure condition within the room. Incorrect ductwork termi- nation and sealing will create a hazardous condition which could lead to bodily harm.

!CAUTION

The ability to properly perform maintenance on this equipment requires certain mechan- ical skills and tools. If you are at all uncer- tain, contact your dealer for qualified maintenance and service.

HERE ARE A FEW DO’S AND DO NOT’S

•DO become familiar with the instructions.

•DO use filters. Check them periodically and make sure that they are clean.

•DO check to see that your home has adequate insula- tion, weatherstripping, caulking, and storm windows. Eliminating infiltration of outside air and drafts can save up to 40% of your fuel bill.

•DO NOT waste fuel by setting your thermostat too

high. Energy conservation experts recommend daytime thermostat setting of 68° F, with a lower setting at night.

•DO NOT turn off the furnace when you expect to be away for more than a day. Instead, lower the thermostat setting by a few degrees. You can then restore normal comfort level quickly and save fuel too.

•DO NOT block registers with furniture.

The operation and care of your unit is simple and easy. By following these operating and maintenance proce- dures, you can expect to receive better, longer, and more reliable service from your new appliance.

COMBUSTION AIR REQUIREMENTS

Combustion air requirements become more important for your new furnace. More efficient units have lower flue temperatures and less natural draft. Especially with new homes and with older homes that have been weatherized (storm windows, vinyl siding, additional insulation, etc.) infiltration air may no longer be enough to supply the necessary combustion air to your furnace. In these cases outside air will need to be in- troduced into the furnace location or directly into the furnace vestibule. This can be accomplished by means of louvered openings, ductwork, or tubing. Your dealer or service technician has access to the necessary air requirements specified by the National Fire Protection Agency.

Some symptoms of a lack of the proper amount of combustion air are:

•DO NOT put a lamp, TV, or radio near your thermo- stat. This will cause it to give a false reading.

HERE’S HOW YOUR

HEATING SYSTEM WORKS

The furnace operates automatically. It is controlled by a thermostat which you set at the temperature most com- fortable to you. When the inside temperature drops be- low this setting, your thermostat starts the furnace.

When the thermostat calls for heat, power from the transformer energizes the fan control board. The fan control energizes the ignition control. The ignition con- trol automatically lights the burner.

The electronic fan control automatically turns on the blower after 30 sec. Fan on control is not adjustable. The air moved over the heat exchanger by the blower is warmed and passes through the ducts to the room regis- ters.

When the thermostat is satisfied, the circuit is de-ener- gized and the primary control shuts off the burner. The blower continues to run until the selectable fan off time period has expired.
