!

CAUTION

To prevent shortening its service life, the furnace
should not be used as a “Construction Heater” during
the finishing phases of construction until the require­ments listed in item 8, a-g of the safety section of this
publication have been met. Condensate in the pres­ence of chlorides and fluorides from paint, varnish,
stains, adhesives, cleaning compounds, and cement
create a corrosive condition which may cause rapid
deterioration of the heat exchanger.

WARNING

SUPPORT FURNACE PROPERLY
DO NOT hang the downflow/ horizontal furnace from
a structure, or surface, by any integral part or fas­tener of the furnace. The furnace was not designed to
support itself in this manner.

In as much as practical, the furnace should be posi
tioned near a chimney or vent and should be centralized
with respect to the air distribution system
For a utility room installation, the entrance door must
be wide enough to permit the largest part of the furnace
to pass through the doorway or allow sufficient clear
ance to permit the replacement of another appliance,
e.g. a water heater, in the room
If the furnace is installed in a residential garage, it
must be installed so the burner is located higher tha
18 inches above the floor. Also, the furnace must be lo-

cated or protected to avoid physical damage from im

pacts by vehicles.
Highboy and lowboy furnace models must rest o
sturdy, stable, and level surfaces.
The downflow/ horizontal model may be mounted on
level surface, as described above, or it may be sus­pended from an overhead structure or surface. If thi
model is suspended from hanger rods, support the

f

urnace from the bottom casing surface at three

(3) places, across

the casing, near the middle of the furnace
Generally, a simple support frame for the furnace can
be fabricated from structural steel angle, threaded stee
rod, and fastener hardware, refer to Figure

CLOSET AND ALCOVE INSTALLATION

All furnace models may be installed in a closet or alcove
on combustible flooring with specified (standard) clear

ances to combustible construction

The horizontal/ downflow furnace model requires
an optional combustible surface-mounting base

(model # BAYSUB10ABASEAA) for vertical instal-
lation (i.e., downflow configuration) directly on
combustible materials, refer to Figure 2.

DOWNFLOW/ HORIZONTAL FURNACE
SETUP

The downflow/ horizontal furnace is shipped from the

factory upright for vertical installation (downflow con­figuration). If the furnace is to be installed lying dow
on the right-hand or left-hand side (horizontal configu-

ration), the positions of the oil burner and the fan an
limit control thermostat may have to be changed. See
Figure 3.
The horizontal furnace may be turned end for end, or
rotated, making the top into the
