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.
