Motor supply voltage must not vary more than 10 percent
from nameplate ratings. At initial startup and at least once a
year thereafter, check the motor current with a meter while
the burner is in high fire position. If the reading exceeds the
nameplate rating plus service factor, determine the cause and
correct it immediately. In dusty locations, clean the motor
regularly to assure adequate cooling. Lubricate in accordance
with the manufacturer's instructions.
Extended Shutdown
When shutting down the burner for an extended period of
time, the operator should use the following general guidelines
to protect the burner from its surrounding elements. This will

Turn the main electrical disconnect switch to the burner
to "OFF."
2.

If the burner operates in a damp environment, cover it
