Steps For Starting Your Furnace - Carrier 58VMR User's Information Manual

DANGER
!
ELECTRICAL SHOCK HAZARD HIGH VOLT-
AGE AT IGNITER.
Severe electrical shock, personal injury, or
death could result.
• If a suspected malfunction occurs with your oil control
system, such as the burner not lighting when it should,
refer to the "Shutting Down Your Furnace" section and
call your dealer as soon as possible.
CHECK AIR FILTER: Before attempting to start
your furnace, be sure the furnace air filter is clean and
in place. See " Performing Routine Maintenance" sec-
tion 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 set-
ting. (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 temperature slightly above
room temperature. This will automatically signal
the furnace to start.
9. When the thermostat calls for heat, power from the
transformer 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 automatically turns on
the blower. 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 continuous 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 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 on extremely cold days. The few
degrees at the top of your thermostat "comfort
level" are the most costly degrees to obtain.
When room temperature drops below temperature
selected on the thermostat, the furnace will be
switched on automatically. When room tempera-
ture reaches the degree selected on thermostat, the
furnace will be switched off automatically.
Some thermostats have a FAN mode with 2 selec-
5
tions, AUTO and ON. When thermostat is set to
AUTO, the furnace blower cycles on and off, con-
trolled by the thermostat. In ON mode, the furnace
blower runs continuously. This keeps the tempera-
ture level in your home more evenly balanced. It
also continuously filters indoor air.
