SAFETY CONSIDERATIONS
Recognize safety information. This is the safety-alert symbol
_. When you see this symbol on the furnace and in
instructions or manuals, be alert to the potential for personal
injury.
Understand the signal words DANGER, WARNING, and
CAUTION. These words are used with the safety-alert symbol.
DANGER identifies the most serious hazards which win result in
severe personal injury or death. WARNING signifies a hazard
which could result in personal injury or death. CAUTION is used
to identify unsafe practices which may result in minor personal
injury or product and property damage. NOTE is used to
highlight suggestions which will result in enhanced installation,
reliability, or operation.

INTRODUCTION
The model 58VLR Furnaces are available in 2 sizes. Each size
can be fired at 3 different rates by a simple nozzle change. Unit
58VLR105 covers input ranges from 70,000 to 105,000 Btuh.
Unit 58VLR120 covers input ranges from 119,000 to 154,000
Btuh.
This furnace is a Low-Boy unit. It may be operated only in the
upflowconfiguration. This furnace is not approved for
installation in mobile homes, recreational vehicles, or outdoors.
The furnace is shipped as a packaged unit. complete with burner
and controls. It requires a line voltage (115 vac) connection to
control box, a thermostat hook-up as shown on wiring diagram,
oil line connection(s), adequate duct work, and connection to a
properly sized vent.
The air handling capacity of this furnace is designed for cooling
airflow. Refer to Table 19 or 20 for expected airflows at various
external duct static pressures.
LOCATION
STEP 1--General
ELECTRICAL SHOCK, OR UNIT DAMAGE
HAZARD
Failure to follow this warning could result in property
damage, personal injury or death.
This furnace is not water tight and is not designed for
outdoor installation. This furnace shall be installed in such
a manner as to protect electrical components from water.
Outdoor installation would lead to a hazardous electrical
condition and to premature furnace damage.
PERSONAL INJURY AND UNIT DAMAGE
HAZARD
Failure to follow this caution may result in equipment
damage or improper operation.
This oil furnace may be used for construction heat provided
that:
-The furnace is permanently installed with all electrical
wiring, piping, venting and ducting installed according to
these installation instructions. A return air duct is provided.
sealed to the furnace casing, and terminated outside the
space containing the furnace. This prevents a negative
pressure condition as created by the circulating air blower.
causing a flame roll-out and/or drawing combustion
products into the structure.
-The furnace is controlled by a thermostat. It may not be
"hot wired" to provide heat continuously to the structure
without thermostatic control.
-Clean outside air is provided for combustion. This is to
minimize the corrosive effects of adhesives, sealers and
other construction materials. It also prevents the
entrainment of drywall dust into combustion air, which can
cause fouling and plugging of furnace components.
-The temperature of the return air to the furnace is
maintained between 60"F (13°C) and 80°F (2W"C) with no
evening setback or shutdown. The use of the furnace while
the structure is under construction is deemed to be
intermittent operation per our installation instructions.
-The air temperature rise is within the rated rise range on
the furnace rating plate, and the firing rate has been set to
the nameplate value.
-The filters used to clean the circulating air during the
construction process must be either changed or thoroughly
cleaned prior to occupancy.
-The furnace, ducrwork and filters are cleaned as necessary
to remove drywall dust and construction debris from all
HVAC system components after construction is completed.
-After construction is complete, verify furnace operating
conditions including ignition, input rate, temperature rise,
and venting, according to the manufacturer's instructions.

The required minimum clearances for this furnace are specified in
Table 1.
This furnace is approved for reduced clearances to combustible
construction, therefore, it may be installed in a closet or similar
enclosure. It may be located in a basement or on the same level as
area to be heated. In any case, unit should always be installed
level.
The furnace should be located as close as possible to chimney or
vent in order to keep vent connections short and direct. The
furnace should also be located as near as possible to center of air
distribution system.
STEP 2--Location Relative to Cooling Equipment
When installing furnace with cooling equipment for year-round
operation, the following recommendations must be followed for
series or parallel airflow:
1. In parallel akflow applications, dampers must be provided
to direct air over furnace heat exchanger when heat is
desired and over cooling coil when cooling is desired.
2. In series airflow applications, coil is mounted after furnace
in an enclosure in supply-air stream. The furnace blower
is used for both heating and cooling airflow.
The requirements for combustion and ventilation air depend upon
whether or not the furnace is located in a space having a volume
of at least 50 cubic feet per 1,000 Btuh input rating for all
appliances installed in the space.
• Spaces having less than 50 cubic feet per 1,000 Btuh require the
OUTDOOR COMBUSTION-AIR METHOD.
• Spaces having at least 50 cubic feet per 1,000 Btuh may use the
INDOOR COMBUSTION-AIR, STANDARD- or
KNOWN- AIR-INFILTRATION METHOD.
CARBON MONOXIDE POISONING HAZARD
Failure to follow this warning could result in personal injury
or death.
The operation of exhaust fans, kitchen ventilation fans.
clothes dryers, attic exhaust fans or fireplaces could create a
NEGATIVE PRESSURE CONDITION at the furnace.
Make-up air MUST be provided for the ventilation devices,
in addition to that required by the furnace. Refer to the
Carbon Monoxide Poisoning Hazard warning in the venting
section of these instructions to determine if an adequate
amount of make-up air is available.
UNIT DAMAGE HAZARD
Failure to follow this caution may reduce the life of this
unit.
The coil MUST be installed on air-discharge side of
furnace. Under no circumstances should airflow be such
that cooled, conditioned air can pass over furnace heat
exchanger. This will cause condensation in heat exchanger
and possible failure of heat exchanger. Heat exchanger
failure due to improper installation may not be covered by
warranty.
IMPORTANT: The dampers should be adequate to prevent
cooled air from entering furnace. If manually operated, dampers
must be equipped with a means to prevent operation of either
cooling unit or furnace unless damper is in full cool or heat
position.
INSTALLATION
STEP 1 --Air for Combustion and Ventilation
Provisions for adequate combustion, ventilation, and dilution air
must be provided in accordance with:
• U.S. Installations: Section 8.3 of the NFGC, Air for Combustion
and Ventilation, and applicable provisions of the local building
codes.
•Canadian Installations: Part 7 of the NSCNGPIC, Venting
Systems and Air Supply for Appliances, and all authorities
having jurisdiction.
STEP 2 --Outdoor Combustion-Air Method
1. Provide the space with sufficient air for proper
combustion, ventilation, and dilution of flue gases using
permanent horizontal or vertical duct(s) or opening(s)
directly communicating with the outdoors or spaces that
freely communicate with the outdoors.
2. Fig. 4 illustrates how to provide TWO OUTDOOR
OPENINGS, one inlet and one outlet combustion and
ventilation air opening, to the outdoors.
a. One opening MUST commence within 12" (300 mm) of
the ceiling and the second opening MUST commence
within 12" (300 mm) of the floor.
b. Size openings and ducts per Fig. 5 and Table 2.
c. TWO HORIZONTAL DUCTS require 1 square inch of
free area per 2.000 Btuh (1,100 mm2/kW) of combined
input for all appliances in the space per Fig. 4 and Table
2.
d. TWO OPENINGS OR VERTICAL DUCTS require 1
square inch of free area per 4,000 Btuh (550 mm2/kW)
for combined input of all appliances in the space per
Fig.4 and Table 2.
