Platform Furnace Support

Construct working platform at location where all required furnace clearances are met. (See Fig. 2 and 17.) For furnaces with 1-in. (25 mm) clearance requirement on side, set furnace on non-combustible blocks, bricks or angle iron. For crawlspace installations, if the furnace is not suspended from the floor joists, the ground underneath furnace must be level and the furnace set on blocks or bricks.

Roll-Out Protection

Provide a minimum 17-3/4-in. x 22-in. (451 x 559 mm) piece of sheet metal for flame roll-out protection in front of burner area for furnaces closer than 12 inches (305 mm) above the combustible deck or suspended furnaces closer than 12 inches (305 mm) to joists. The sheet metal MUST extend underneath the furnace casing by 1 in. (25 mm) with the door removed.

The bottom closure panel on furnaces of widths 17-1/2 in. (445

312AAV

mm) and larger may be used for flame roll-out protection when

bottom of furnace is used for return air connection. See Fig. 17.

 

 

for proper orientation of roll-out shield.
