WARNING
!
THIS FURNACE IS DESIGN
CERTIFIED TO OPERATE ON #2
FUEL OIL. DO NOT ATTEMPT TO
CONVERT THIS FURNACE TO
BURN NATURAL GAS OR LP GAS.
FAILURE TO FOLLOW THIS
WARNING CAN CAUSE A FIRE OR
EXPLOSION RESULTING IN
PROPERTY DAMAGE, PERSONAL
INJURY OR DEATH.

LOCATION

WARNING
!
THIS FURNACE IS NOT APPROVED
FOR INSTALLATION IN A MOBILE
HOME. DO NOT INSTALL THIS
FURNACE IN A MOBILE HOME.
INSTALLATION IN A MOBILE HOME
COULD CAUSE FIRE, PROPERTY
DAMAGE AND PERSONAL INJURY
OR DEATH.
Locate furnace as close to chimney as
practical, giving considerations to duct
trunk lines and accessibility of oil
burner, controls, blower and filter. For
basement installation, if there is no
level concrete floor or if water may be
encountered, a level concrete base
should be provided. Allow a minimum
of twenty-four inches at front of furnace
for servicing oil burner and controls.
Fire protection clearances are printed
in figure 1 and on the rating plate of the
furnace.
An oil-fired furnace installed in a
residential garage must be located or
protected to avoid physical damage by
vehicles.
This furnace is approved for installation
indoors only. Do not install unit
outdoors.
WARNING
!
COMBUSTIBLE MATERIAL MUST
NOT BE PLACED ON OR AGAINST
THE FURNACE JACKET. THE AREA
AROUND THE FURNACE MUST BE
KEPT CLEAR AND FREE OF ALL
COMBUSTIBLE MATERIAL
INCLUDING GASOLINE AND OTHER
FLAMMABLE VAPOR OR LIQUIDS.
THE HOMEOWNER SHOULD BE
CAUTIONED THAT THE FURNACE
AREA MUST NOT BE USED AS A
BROOM CLOSET OR FOR ANY
OTHER STORAGE PURPOSES.
COMBUSTIBLE MATERIAL PLACED
AGAINST FURNACE JACKET COULD
CAUSE FIRE, PROPERTY DAMAGE,
PERSONAL INJURY OR DEATH.

COMBUSTION AIR SUPPLY

WARNING
!
THIS FURNACE MUST BE PROVIDED
WITH ENOUGH FRESH AIR FOR
PROPER COMBUSTION
VENTILATION OF FLUE GASES.
SOME HOMES MAY REQUIRE THAT
OUTSIDE AIR BE SUPPLIED TO THE
FURNACE AREA. FAILURE TO
PROVIDE ENOUGH FRESH AIR CAN
CAUSE DEATH FROM CARBON
MONOXIDE POISONING.
Adequate facilities for combustion and
ventilation must be provided in
accordance with section number 1-5,
"Air for Combustion and Ventilation," of
the Standard for Installation of Oil
Burning Equipment, NFPA No. 31 , latest
edition or other applicable provisions of
local building codes. The flow of com-
bustion air to the furnace area must not
be obstructed.
Important: Air for combustion and
ventilation must not come from a
corrosive atmosphere. Any failure due
to corrosive elements in the atmosphere
is excluded from warranty coverage.
Combustion air must be free of acid-
forming chemicals such as sulphur,
fluorine and chlorine. These elements
are found in aerosol sprays, detergents,
bleaches, cleaning solvents, air
fresheners, paint and varnish removers,
refrigerants and many other commercial
and household products. Vapors from
these products when burned in a flame
form acidic compounds and are highly
corrosive when they condense.
When appliances are installed within a
confined space and combustion air is
taken from within the heated space, the
air supply must be through two
permanent openings of equal area, one
located within 12 inches of the ceiling
and one within 12 inches of the floor
(see figure 4). Refer to the rating plate
label on the furnace for information on
the minimum free area of these two
openings.
FIGURE 4
OPENINGS FOR CONFINED SPACES
AND
When appliances are installed in an
unconfined space in a building of con-
ventional frame, brick or stone
construction, infiltration normally is
adequate to provide for combustion
ventilation and draft control dilution. If
the unconfined space is within a
building of unusually tight construction,
a supply of combustion, ventilation and
draft control dilution air must be
obtained from outdoors or spaces freely
connected to the outdoors. Under these
conditions a permanent opening or
openings having a total free area of not
less than 1 sq. in. per 5,000 BTUH of
total input rating of all appliances shall
be provided. This code is found in
NFPA 31, Standard for Installation of
Oil Burning Equipment . Other State,
Provincial, and Local codes may apply,
check with local inspectors.
When appliances are installed in a
confined space within a building of
unusually tight construction, air for
combustion must be obtained from
outdoors or from spaces or ducts freely
drawing from the outdoors. Under these
