NOTE: If the burners fail to ignite after 4 attempts, the furnace
control system will lock out. If lockout occurs, main burners fail

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 f urnace will switch on a utomatically .
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. ComfortFant, the blower s peed 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 your thermostat), and
then return to ON. The blower will switch t o the next higher
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.
