BURNER STARTING
Close the control devices and set switch 1)(A) to
"MAN".
As soon as the burner starts check the direction
of rotation of the fan blade, looking through the
flame inspection window 17)(A)p.4.

to the solenoids, or pilot lights on the solenoids
themselves, indicate that no voltage is present.
If voltage is present, then immediately stop the
burner and check electrical connections.

operation (see the layout of electric panel board
p. 20), act on the switch 3) (A).
BURNER FIRING
Having completed the checks indicated in the
previous heading, the burner should fire. If the
motor starts but the flame does not appear and
the control box goes into lock-out, reset and wait
for a new firing attempt. If firing is still not
achieved, it may be that gas is not reaching the
combustion head within the safety time period of
3 seconds.
In this case increase gas firing delivery.
The arrival of gas at the sleeve is indicated by
the manometer (C) p. 10.
Once the burner has fired, now proceed with
global calibration operations.
