HOW YOUR GAS FURNACE WORKS
Your furnace is a very easy appliance to take for granted. Season after season, it sits there in your home, keeping you warm and comfortable. For this reason, you may never have given much thought to the way your furnace operates. In order to get the safest and most efficient operation from your furnace, though, you should understand how your fur­nace does its job.
When you set your thermostat to provide more heat in your home, you are starting the heating cycle of the furnace. First, the inducer motor starts to purge the heat exchanger of any remaining gas­ses. Next, the hot surface ignitor glows and after a warm-up period the gas valve opens and ignition occurs. A short time later the blower starts and distributes the warm air throughout the home. When the temperature set on your thermostat is reached, the gas valve closes, the main burners are turned off, and the blower continues to run until the remain­ing warm air in the system is distributed. When the blower stops, the heating cy­cle has ended.
KEEP THE FURNACE AREA CLEAR
NEVER
furnace as a storage area for items which could block the normal flow of air. This flow of air is required for ventilation of the various furnace components.
NEVER
any kind near your furnace. Gasoline, sol­vents, and other volatile liquids should be stored only in approved containers outside your home. These materials vaporize eas­ily and are extremely dangerous.
NEVER
near your furnace. Materials such as bleaches, detergents, powdered cleans­ers, etc., can cause corrosion of the heat exchangers.

1. On the furnace.
2. Air openings communicating with the air in which the furnace is installed.
3. The spacings around the furnace.

WARNING: Insulating materials may be flammable.
CAUTION: When a furnace is installed in an attic or other insu­lated space, or if insulation is added, examine the furnace area to ensure that the furnace is kept clear and free of insulation.
ST ART -UP AND SHUTDOWN ­GENERAL INSTRUCTIONS
Read and follow these procedures CAREFULLY and COMPLETELY.
Before attempting to start your furnace, always do the following things FIRST:
Turn the thermostat OFF.
Open windows or make other provi-
sions to ventilate the area around the furnace.
If the blower is running, wait until it
shuts off automatically.
Turn off all electrical power to the
furnace.
Make sure all metal surfaces of the
furnace have cooled to room tem­perature before beginning.
FOR YOUR SAFETY, READ BEFORE OPERATING:
WARNING:
not follow these in­structions ex actly , a fire or explosion may re­sult, causing property damage, personal in­jury or loss of life.
A. This appliance does not have a pilot.
It is equipped with an ignition device which automatically lights the burn­ers. Do not try to light the burners by hand.
B. BEFORE OPERATING, smell all
around the appliance area for gas. Be sure to smell next to the floor because some gas is heavier than air and will settle on the floor.

YOUR FURNACE’S FILTER ­WHAT IT DOES
The filter in your furnace takes the lint and dust out of the air that passes through it. This keeps dirt particles from getting into the moving parts of the furnace, where they could cause serious damage. It also keeps the dirt from circulating through your home.
As the filter continues to collect these particles, it becomes clogged and no longer allows enough air to circulate through the furnace. If this happens, the heat exchangers and blower motor could overheat; a potentially dangerous situation. It is very important to keep the air filter clean! Never operate your fur­nace without a suitable air filter.
WARNING:
When replacing fil­ters DO NOT use a type with excessively high pressure drop. Some high efficiency filters avail­able will cause the furnace to operate improperly and could re­sult in a safety hazard.
FREQUENCY OF CHECKING FILTERS
Clean your furnace’s filter at least every three months. If you need to replace a filter, check the filter chart to be sure you install the right size and type of filter for your furnace.
If your home is new, you should check the filter every week for the first four weeks after you begin to use the fur­nace, and then at least every three weeks after that, e specially if the system runs constantly .
NOTE: Some installations may have more than one filter.
LOCATING/REMOVING FILTERS
UPFLOW FURNACES
Most upflow furnaces have their filters located on the side or bottom of the furnace in a filter frame.
If your furnace has this type return filter frame, remove the door by pulling on it. Slide the filter out of its channel. T o re place after cleaning, slide filter into place and snap the door on the end of the filter rack.
Some installations may have filters lo­cated in the blower compartment. Check with the installer for your filter location.

UPFLOW FURNACE BOTTOM MOUNT FILTER RET AINER
To check filters located in the blower compartment, remove the upper furance door by lifting up. Pull out bottom of door and lower from furnace. Remove the blower compartment panel by lifting up.
NOTE: The spring-loaded safety cutoff switch, mounted under the blower deck will automatically cut off the electrical power supply to the furnace when the blower panel is removed.
To remove bottom mounted filter(s) on all furnaces, push the looped end of the filter retainer to the side and then lift up. Reverse the procedure to reinstall filters.
DOWNFLOW FURNACES
The filters in your downflow furnace are located in the plenum or ductwork above the furnace.To check the filters, turn off the electrical supply to the furnace.

HORIZONTAL FURNACE TYPICAL FILTER LOCATION
HORIZONT AL FURNACES
Most horizontal furnaces have their fil­ters located in a filter grille(s) so that it may be easily changed without gaining access to the attic or crawlspace.
Some installations may have a filter rack near the furnace. With this type of acces­sory , unsnap the filter rack door and pull. The filter is attached to the door and will slide out. If you are unsure where the furnace filter is installed, check with the installer.
HOW TO CLEAN YOUR FURNACE’S FILTER
High-velocity filters may be cleaned with a vacuum cleaner or washed with a gar­den hose. Be sure to shake off excess water before re-installing the filter.
MOTO R L U B R ICA T IO N
The motors in these furnaces are perma­nently lubricated, and require no peri­odic oiling.
INST ALLA TION AND MAINTENANCE INSTRUCTIONS
YORK strongly recommends regular pe­riodic preventative maintenance on this equipment.
In order to ensure safe, reliable opera­tion and long product life, it is recom­mended that the entire heating system be inspected annually by a qualified service person.
The person most familiar with the equip­ment in your system is a YORK dealer. The YORK dealer can ensure your main­tenance program meets the conditions of the "YORK Warranty", maximize the efficiency of the equipment, and service your unit within the mandated guidelines with regard to unlawful discharge of re­frigerants.
The inspection should include heating element, vent piping, to see that they are clear and free of obstructions and with­out holes or corrosion. Make sure the horizontal run of the vent system slopes upward and all of the connections are secure. Make sure the return air duct connections are physically sound and sealed to the furnace casing. Make sure no sagging, cracks, gaps, etc. exist around the base of the furnace.
Routine periodic maintenance checks should be done on your furnace at least every time you check the filters. Proper burner flame appearance is shown below .

CAUTION: Before proceeding, be sure the area is well venti­lated. T urn the thermostat OFF. If the blower is running, wait until it stops automatically. Turn OFF the gas and electrical power sup­plies to the furnace. Check all metal parts and surfaces to be sure they have cooled to room temperature before you begin.
Remove the front panels and turn the knob on the gas control to the OFF po­sition. Check the following items:
Check for dust and lint on the sensor
and main burners.
Check the vent pipe and chimney for
blockage, corrosion or leakage or any obstructions.
