(Accessories)
1. The air discharge diverter duct provides improved
directional air flow and greater heat throw,
beneficial in heating long houses. Use the duct
only on indoor mounted heaters. Do not use
the diverter when the heater is mounted outside
the greenhouse. The diverter duct requires hand
forming prior to assembly. Make 90 degree bends
utilizing the perforations provided. Assemble as
shown in Fig. 1.

Indoor Ventilation
Requirements
This heater requires a properly sized motorized air
inlet shutter, flexible duct, and exhaust fan. All items
must be installed when the heater is located within the
greenhouse. These components, along with specific
instructions, are provided in the indoor ventilation kit,
part number 500-25985.
Air Inlet
Ideally the air inlet shutter should be located as shown
in Fig.4a, 4b, and 4c. However, it may also be installed
in any other location on an end or side wall, especially
if water, gas, or electrical lines create interference. See
Fig.4d for alternate locations at end or side walls.
Regardless of air inlet location, the flexible duct
(included with the ventilation kit) must be installed.
The duct must be cut to proper length to prevent
sagging and kinks from preventing proper air flow to
the heater. Separate duct installation instructions are
provided in the duct kit.
Ensure the motorized air inlet and the heater’s air inlet
are kept free of any blockages.
