7.Replace main furnace door. (See Fig. 13.)

8.Turn ON the electrical supply to the furnace and wait 1 minute. (See Fig. 14.)

9.Open the external manual gas valve. (See Fig. 15.)

10.Set the room thermostat to a temperature slightly above the room temperature. This will automatically signal the furnace to start.

11.When the furnace receives the start signal, the inducer is started. When the pressure switch senses that there is suf- ficient combustion air, the hot surface igniter is energized. After the hot surface igniter is heated for 17 seconds, the gas valve permits gas to flow to the main burners. After ignition and a time delay of about 30 sec, the furnace blower will start. Variable-capacity furnaces start at medium speed until the control makes the necessary adjustments to operate the blower at either the low-, medium-, or high-heat speed.

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 temperature that satisfies your comfort requirements.

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

When the room temperature drops below the temperature selected on the thermostat, the furnace will switch on automatically. When the 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 set on AUTO, the furnace blower cycles on and off. In the ON mode, the furnace blower runs continuously. Continuous fan keeps the temperature level in your home more evenly balanced. It also permits the indoor air to be continuously filtered. With the unique feature Fan On Plust, 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 for 1 to 3 seconds (or AUTO depending on
