HAZARD
Failure to follow this warning could result in personal injury, death, or
property damage.
Do not install the furnace on its back or hang furnace with control
compartment facing downward. Safety control operation will be
adversely affected. Never connect return−air ducts to the back of the
furnace.
Suspended Furnace Support
The furnace may be supported under the entire length of the
furnace with threaded rod and angle iron. (See Figure 24)
Secure angle iron to bottom of furnace as shown.
Platform Furnace Support
Construct working platform at location where all required
furnace clearances are met. (See Table 1 and Figure 25) 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.
