Carrier
Upflow and Downflow Gas-Fired Furnaces
HANG ON WALL NEAR FURNACE
This 58B unit has been approved by the American Gas Association Laboratories and carries all required safeguards against fires and accidents. Such occurrences will take place only if the unit is mistreated or not properly maintained.
The operation and care of your unit is simple and easy. By following these operating and main tenance procedures, you can expect to receive better, longer, and more reliable service from your new Carrier appliance.
Here Are a Few "Do's" and "Don'ts"
•Do become familiar with wallcard instructions.
•Do use filters Check them periodically and make sure that they are clean.
•Don't set your thermostat too low. Ideal comfort zone is usually between 72 F and 78 F
•Don't be a “thermostat jiggler.” Frequent changing of your thermostat can increase your operating costs.
•Don't turn your furnace off just because you’ll be away for a day or more. It takes quite a while to restore comfort — but it costs rela tively little to maintain it.
•Don't block registers with furniture. Don’t put a lamp, TV or radio too near your thermostat. This will cause it to give a “false” reading.
Here's How Your Heating System Works
The furnace operates automatically. It is con trolled by a thermostat which you set at the temperature most comfortable to you. When the inside temperature drops below this setting your thermostat senses this and turns on the system.
First the gas valve opens, and the burners are lighted by your pilot. After a few moments, the blower turns on automatically. The air it moves over the element is warmed and goes on thru the ducts to room registers.
When the temperature in the room reaches the thermostat setting, the gas valve closes and the burners are turned off. The blower continues a few moments until the heat in the element is used up. Then it turns off, too.
All forced air furnaces are equipped with high temperature limit switches (one on most upflow models, two on other types) that prevent the furnace from overheating by turning off the burners if the blower fails to come on. Except on downflow furnaces, these switches should recycle automatically, causing the burner to go on and off. On downflow models, the second of the two switches used requires manual reset. (Reset button is on furnace top.)
Here's How You Get Greater Satisfaction
The following steps are very easy to perform. So before you get ready to light your furnace pilot make sure that you have gone thru the list.
1. Open all warm air registers and make sure that all return air grilles are unobstructed.
2.Set room thermostat below room temperature.
3.If a humidifier is installed with your system, open the water supply valve.
4.If a line voltage switch is provided in the furnace circuit, make sure that it is turned to the “Off” position.
5.Make sure that the main burner and pilot manual gas shutoff valves are closed. “On”and “Off ” positions are clearly marked.
6.Wait five minutes for unit to be purged of gas, and then get ready to start the burner.
STARTING YOUR BURNER - Lighting in structions are also shown on rating plate located on or near burner compartment door. Should any doubt exist in your mind concerning proper lighting procedures, call your gas serviceman to light unit.
1. After five minute wait for unit to be purged of gas, turn unit electric switch to “Off.”
2.Open the pilot manual gas shutoff valve.
3.Light the pilot with a match or taper.
NOTE. If your unit is equipped for 100 percent shutoff, it will be necessary to reset the safety valve before you can relight the pilot
5.Open the main burner manual gas shutoff valve.
6.Turn the unit electric switch to “On.”
7.Set your thermostat to the desired room temperature. On heating/cooling systems, set the system switch to “Heat,” and the fan switch to “Auto.” or “Cont.” That’s all there is to it.
OPERATING FAN CONTINUOUSLY (FAN SWITCH SET ON “CONT”) - Your distribution system will perform at its best if the furnace fan is run continuously when weather outdoors is 40 F or less. This will eliminate cold floors and hot ceilings and provide for a more constant temperature.
1. On heating only models, turn the summer switch (located on the furnace) to the “On” position.
2.On heating/cooling models, turn the thermostat fan switch to “Cont.”
3.If your needs are not met by Step 1 or 2, see your dealer for specific instructions.
