Connecting the Optional Thermostat

into the terminal strip located in the left rear corner of the
heater.

a special low resistance thermostat. Do not use a regular
heating thermostat.
Be sure that all electrical connections are clean, free
from corrosion, and tight. inspect connections periodically
to confirm that no corrosion has built up over time.
When properly installed and maintained, a millivolt
control system should give many years of trouble-free
service.
