

Spacing of 1/4" to ducting within 3 feet of furnace must be provided

unless UL listed wire bound vinyl ducts are used. All ducting material

must be rated for continuous use at minimum of 200°F.



Clearances are specifically for plywood or similar building materials

surrounding the furnace (i.e. Furnace should not be located under

furniture or in a closet space where clothing or other material could be

located).



Furnace efficiency rating is a thermal rating determined under

continuous operating conditions, independent of any installation.

Efficiency rate is given at 76% minimum; actual efficiency rating may

be higher.



Return air is supplied through openings or around the furnace. All

return air passages must be kept clear for furnace to function properly.

Refer to Minimum clearance to floorboards, walls & similar combustible

building material in Table 4.



The total unobstructed return air opening size must not be less than

specified in specification Table 1. Failure to meet minimum return air

requirements nullifies furnace warranty.



To install without adding the additional 16 sq. in. cutout on the blower

side supply the right side of unit (blower side) with 2" clearance full

length of the unit.
