CHECK AIR FILTER: Before attempting to start your furnace, be sure the furnace air filter is clean and in place. See “Performing Rou- tine Maintenance” section in this manual. Then proceed as follows:

STEPS FOR STARTING YOUR FURNACE

1.Open all warm air registers and make sure that all return-air grills are unobstructed.

2.If a humidifier is installed with your system, open water supply valve.

3.Make sure blower access door is secured in place.

4.Set your room thermostat to lowest temperature setting. (See Fig. 5.)

5.Turn on electric power to furnace. (See Fig. 6.)

6.Open oil supply valve. (See Fig. 7.)

7.Check all connections to ensure there are no leaks.

8.Set room thermostat to a tem- perature slightly above room temperature. This will auto- matically signal the furnace to start.

9.When the thermostat calls for heat, power from the trans- former energizes the fan control board. The fan control energizes the ignition control. The igni- tion control will automatically light the burner.

The electronic fan control auto- matically turns on the blower after 60 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 registers.

This unit is equipped with con- tinuous ignition control. If the main burner does not ignite within 30 sec from the call for heat, the control will lock out. The red button on top of the control must be depressed for 3 sec in order to reset the control. The control CANNOT be reset from the room thermostat.

10.Set your thermostat to the tem- perature that satisfies your com- fort requirements. SUGGES- TION: Setting the thermostat back a few degrees and compen- sating for the difference with warmer clothing can make a big difference in your fuel consump- tion on extremely cold days. The few degrees at the top of your thermostat “comfort level” are the

5

most costly degrees to obtain.

When room temperature drops below temperature selected on the thermostat, the furnace will be switched on automatically. When room temperature reaches the degree selected on the ther- mostat, 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, controlled by the thermostat. In ON mode, the furnace blower runs contin- uously. This keeps the tempera- ture level in your home more evenly balanced. It also contin- uously filters indoor air.

NOTE: Constant low-speed blower operation can also be achieved by turning on the constant blower rocker switch located on side of control box. Regardless of room thermostat setting, blower will run continuously in low speed to pro- vide constant air circulation. If constant blower rocker switch is turned off, room thermostat will control blower operation.

SHUTTING DOWN

YOUR FURNACE

Should you need to shut down your furnace for service or mainte- nance, you will need to turn the furnace off. The following proce- dures must be followed:

1.Set thermostat to lowest setting. (See Fig. 8.)
