EXPLOSION HAZARD
Do NOT store or use gasoline or other flammable va­pors and liquids in the vicinity of this or any other ap­pliance.
Improper installation, adjustment, alteration, service, or
maintenance can cause a fire or explosion resulting in

!

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.

on the right-hand or left-hand side (horizontal configu-

ration), the positions of the oil burner and the fan an

Often, household chemicals contain chloride-bearing

compounds. There are many compounds representative
of this classification of chemicals. A few common ex-

amples are listed below

-Cleaning solvent

- Varnish and paint remover

-Bleaches

-Fabric softener

-Water softener salt

-Tile adhesive
Avoid storing or using these chemicals within close

proximity to the furnace. In addition, avoid storing o
using any chemicals, of an unknown and possibly flam­mable nature, in close proximity to the furnace. If it is
necessary to store or use chemicals in the same spac
as the furnace, the area should be well-ventilated an
all containers should be sealed when not in use. If pos
sible, keep chemicals in a separate, well ventilated
room closed
The furnace shall be installed in a location within the
building that permits a satisfactory supply of air fo

combustion, ventilation, and proper operation of the

venting system. While all forms of building constructio

cannot be covered in detail in this installer's guide, this

requirement may usually be met by application of on

of the following methods in ordinary

CHIMNEY INSPECTION

The chimney, vent, or any passageway for the stac
gases to flow to the outdoor atmosphere is a very im
portant part of the heating system. No furnace, regard
less of the efficiency of the design, can perform satisfa
torily when the chimney to which it is connected is in
adequate or in poor condition

Any of the following symptoms may indicate a chimney

has severe structural damage and is unsuitable for use:

-Chimney appears to be leaning to the side.

-Chimney appears to have structural damage, i.e

loose or missing blocks or bricks, or excessive deteri
ration at mortar joints

-Tile liner damaged or missing

-Flue gas leakage along the length of the chimney be-

tween the chimney connector and discharge termina­tion.

-Excessive corrosion at the cleanout port or at th
chimney connector entrance into the chimney

-Structural debris, i.e. mortar or tile liner flakes, in

base of the flue way

A qualified person shall inspect the chimney to confirm

it is correctly sized for the application, properly con­structed, and in sound condition

for the Installation of Oil-Burning Equipment, NFPA

2001, for details on proper chimney sizing and construc­tion. If needed, the chimney should be cleaned before

CHIMNEY SIZING:

The furnace must be connected to an adequate chimney

or an approved vent in a

lined with the capab
draft and having the capacity to handle the amount of
stack gases that are introduced into it. A chimney wit

PREVENTION OF CHIMNEY CONDENSING:

!

WARNING

PROPER VENTING REQUIRED!
Improper venting may lead to condensation in the
chimney. This may result in property damage, injury,
or loss of life. To prevent condensation refer to NFPA
31 Section 6 and Appendix E.

Stack gas may do one of two things as it escapes u
the chimney

A. Remain entirely in a gaseous state if the interna
chimney wall temperature is above the dew point, or

B. Condense water vapor on the chimney walls if the

Condensing will always
temperatures are below the dew point

condensate may evaporate when the walls war

above the dew point. If the chimney wall temperatur
does not exceed the dew point during the heating

cycle of the furnace, the moisture may accumulate in

large enough quantities to cause problems such a

corrosion of a metal chimney (especially plain steel o

galvanized steel), erosion and break up of a tile liner
in a masonry chimney and, in severe cases, corrosio

of the heat exchanger. Condensate also could enter

the home through cracks or joints in the chimney in
a worse case situation.
Condensation most likely w

FUEL SYSTEM INSTALLATION

In situations where the oil storage tank is installed a

oil tank is installed

return line are necessary. See Figure
Refer to the
Equipment, NFPA
instructions for detailed information on oil storage tank

& oil supply/ return line installation.

NOTICE: We recommend installing a high effi­ciency oil filter, in the oil supply line, capable of fil-

tering 10 to 20 micron diameter (or preferably
smaller) particles from the fuel.

If available, the use of ultra-low or low sulfur (less
than 0.0015%
spectively), no. 2 fuel oil is highly recommended.

Low sulfur fuel oil can help to significantly reduce in­stances of

A disconnect switch equipped with overcurrent prote

tion (e.g. a time delay-type fuse or inverse time, circui
breaker) should be installed in the service line for shut­ting down and protecting the furnace and electrical sys
tem

.
Since the furnace is entirely pre-wired at the factory, i
is only necessary to connect the

building electrical ser-

vice lines to the two (2) pigtail wires extending from th

fan center junction box. The fan center is mounted in

side the furnace burner compartment or mounted o
the front exterior of the furnace, in the case of th
downflow / horizontal

furnace should be no smaller than

model. The service lines to th

., insulated cop
per wire with a temperature rating of 60ºC, or greater.
Connect an equipment ground wire to the furnace a
the fan center junction box. If wiring is run through
metal electrical conduit, it may not be necessary to run
a separate equipment ground wire. Consult local codes
