Heat Commander Furnace Installation and Operation Manual

Appendix 1: Optional air filters (AC01390, AC01391)

The filter option (AC01390 – cardboard frame or AC01391 – washable aluminum) allows

filtrating dirt before distribution warm air in your installation in addition of protecting your

blower. This system can be installed on either sides of the blower box located behind the

furnace on the most convenient of your installation. This option includes the filter, the filter

holder, two caps and the screws necessary for the installation.

Clean and replace filters as often as required.

Note: The operation cost is higher and the overall efficiency is reduced when using a

dirty filter.

1 filter holder

2 caps

1 filter (15" x 20" x 1")

WARNING: IT IS NOT RECOMMENDED TO OPERATE THE FURNACE WITHOUT

FILTERS. THIS APPLIES ESPECIALLY TO TEMPORARY HEATING DURING

CONSTRUCTION PERIOD. OPERATING THE FURNACE WITHOUT FILTERS WOULD

ALLOW DUST AND OTHER PARTICLES IN THE AIR TO CIRCULATE FREELY AND TO

PENETRATE INTO THE BLOWER AND MOTOR CARTERS, CAUSING SOME

DEFECTS.
