TO SHUT DOWN THE HEATER FOR

SHORT PERIOD:

Adjust the room temperature controller to its lowest

setting or "OFF". The fan will continue to run for a

short period to cool the heat exchanger. The pilot will

remain alight.

WARNING: The electrical isolator

should only be used in an emergency and

should not be used for closing down the

main burner, as it switches off the fan pre-

maturely and may damage the heat ex-

changer, invalidating the warranty.
