Clean and replace filters as often as required.

WARNING

IT IS HIGHLY RECOMMENDED TO OPERATE THE FURNACE WITH FILTERS. THIS

APPLIES ESPECIALLY TO TEMPORARY HEATING DURING CONSTRUCTION

AND OTHER PARTICLES IN THE AIR TO CIRCULATE FREELY AND TO

PENETRATE INTO THE BLOWER AND MOTOR CARTER, CAUSING SOME

DEFECTS.
