THERMOSTAT INSTALLATION (continued)

N.B.: It is possible to change the setting of your unit such that
if the thermostat does not call for heat after 45 minutes, the
unit will remain at the lowest heat setting (#1) but will not shut
down (this is the PILOT ON mode). The stove will remain at
the lowest heat level until the thermostat calls for heat again.
If you prefer that your unit runs following that logic, you need
to change the setting to PILOT ON by simultaneously pressing
the following two buttons on the PC Board for a couple of
seconds:
and
Once you do that, the letters P, I, L, O, T, O, N will appear on
the PC Board to let you know that you are in the "PILOT ON"
mode. If you wish to go back to the default thermostatic mode
(i.e. the unit shuts down after 45 minutes if the thermostat
does not call for heat), simply press the same two buttons
again for a couple of seconds. The letters P, I, L, O, T, A, U,
T, O will appear on the PC Board to let you know that you are
in the "PILOT AUTO" mode.
NOTE: When in thermostatic mode:

You should not operate the manual control or play with the
temperature setting.

YOUR THERMOSTAT SHOULD BE INSTALLED BY AN
AUTHORIZED DEALER OR SERVICE PERSON.
