INSTALLATION
It is imperative that this unit is installed and operated with the designed airflow, gas, and electrical supply
in accordance with this manual. If there are any questions about any items, please call the service
department at 1-866-784-6900 for warranty and technical support issues.
Mechanical
WARNING: DO NOT RAISE VENTILATOR BY THE INTAKE HOOD, BLOWER OR
MOTOR SHAFT, OR BEARINGS – USE LIFTING LUGS PROVIDED OR A SLING
Site Preparation
1) Provide clearance around installation site to safely rig and
lift equipment into its final position. Supports must
adequately support equipment. Refer to manufacturer’s
estimated weights.
2) Consider general service and installation space when
locating unit.
3) Locate unit close to the space it will serve to reduce long,
twisted duct runs.
4) Do not allow air intake to face prevailing winds. Support
unit above ground or at roof level high enough to prevent
precipitation from being drawn into its inlet. The inlet must
also be located at least 10 feet away from any exhaust
vents. The heater inlet shall be located in accordance with the applicable building code
provisions for ventilation air. If in doubt regarding the application, consult the manufacturer. All
ventilation air to the heater shall be ducted directly from the outdoors.
5) Recirculation of room air may be hazardous in the presence of:
a) Flammable solids, liquids and gases
b) Explosive materials (e.g., grain dust, coal dust, gunpowder, etc.)
c) Substances which may become toxic when exposed to heat (e.g., refrigerants, aerosols, etc.)
6) Recirculation is not recommended in uninsulated buildings where outside temperatures fall below
32°F (0°C).
7) Excessive recirculation or insufficient ventilation air, which results in inadequate dilution of the
combustion products generated by the heater, may create hazardous concentrations of carbon
dioxide, carbon monoxide, nitrogen dioxide, and other combustion products in the heated space.
8) If gas fork trucks or other fossil fuel powered equipment are utilized in the conditioned area,
additional ventilation requirements for the facility must be addressed separately.
9) If the heater utilizes room sensors for limiting room CO
2
concentration:
a) The CO
2
control set-point shall be no greater than the maximum allowable room
concentration of 5000 ppm less the sensor’s published accuracy tolerance. The control shall
prevent the CO
2
concentration in room air from exceeding 5000 ppm.
b) A minimum of one sensor shall be installed per room served by the heater.
c) When a room area, served by a single heater, does not exceed 10,000 ft
2 (929 m 2 ) and height
does not exceed 20 ft (6 m), a duct sensor may be installed in the return air opening of the
heater.
d) Sensors shall be calibrated per the sensor manufacturer’s recommended procedure and
frequency or annually, whichever is more frequent.
e) Sensors shall not be place near sources of CO
2
.
f) Each heater shall require its own CO
2
sensor(s).
CLEARANCES
The top, back, and front
surfaces of this heater may not
be installed less than 6” from
combustible materials. The
heater base may be installed
on
combustible surfaces.
Allow 24” minimum service
clearance on both sides of this
heater.
