NOTE: If the burners fail to ignite after 4 attempts, the furnace control system will lock out. If lockout occurs, main burners fail to light, or blower does not come on, shut down the furnace and call your dealer for service.

12.Set your thermostat to the temper- ature that satisfies your comfort requirements.

SUGGESTION: Setting the ther- mostat back a few degrees and compensating for the difference with warmer clothing can make a big difference in your fuel con- sumption. The few degrees at the top of your thermostat “comfort level” are the most costly degrees to obtain.

When room temperature drops below the temperature selected on the thermostat, the furnace will be switched on automatically. When room temperature reaches the temperature selected on the thermostat, the furnace will be switched off automatically.

Some thermostats have a FAN mode with 2 selections, AUTO and ON. When thermostat is set to AUTO, the furnace blower cycles on and off. In ON mode, the furnace blower runs continu- ously. Continuous fan keeps the temperature level in your home more evenly balanced. It also per- mits the indoor air to be continu- ously filtered. Fan On Plus™ –On all but the 340MAV, the blower speed can be increased or decreased if desired due to change of seasons, large gatherings in your home, etc. Simply change your FAN from ON to OFF (or AUTO depending on your thermo- stat), and then return to ON. The blower will switch to the next highest speed. There are at least 3 speeds to choose from. If the blower is running on its highest speed, a request to change will direct the blower to return to its lowest speed.

YOUR FURNACE

Should you need to shut down your furnace for service or maintenance, you will need to turn the furnace off.
