2. The burner blower will start.
3. The burner will start firing.
In applications in which the remote thermostat is not being used (I), the
burner will fire continuously.
In applications in which the remote thermostat is being used (II), the burner
will fire until the air temperature of the application area reaches the target
temperature set by the remote thermostat. At that time, the burner will shut
off, but the blower will continue to operate. When the air temperature of the
application area falls below the target temperature set by the remote thermo-
stat, the burner will refire. The process continues as long as there is fuel for
the burner.
4. The main blower will begin blowing warm air when the combustion chamber is
hot.
