This product is designed for zero clearance, but use the following mounting and spacing criteria:
1. Unit can be installed vertically or horizontally. When vertical, inlet must face down.
2. Observe the airflow direction decal and the inlet decal.
3. Make mounting provisions for a 1" air space at the top.
4. The sides, any location, can be in direct contact with wood framing materials.
5. No materials shall be in contact with the cabinet housing which has a flame point less than wood,
300°F (150°C).
6. Product shall be installed in a conditioned space only.
7. Heating elements are locked out when outlet air temperature is > set point dial switch.
General:
1. Select a location which will provide minimal noise vibration and minimal fan noise to the
building occupants.
2. The outside hood and ducting material are not included with this unit. It is the installer's
responsibility to provide the necessary weather protection for the inlet.
In cold climates, insulated ducting must be used between the outside inlet air hood and the
inlet of this unit.
3. Install unit with a slight air inlet incline (housing outlet end is ¼" higher than inlet end).
4. The unit can be mounted within the ceiling (between joists where it will fit) or ceiling hung, at
any convenient location between the outside inlet hood and the fresh air discharge connection.
The discharge connection is wherever the conditioned fresh air is distributed within the
building – furnace cold air return, special ducting, hallway register, furnace room, etc.
5. 6" inlet and outlet ducting is adequate for these two mini models.
Note: In cold climates, frost and or condensation may collect on metal parts of this product. External field
provided insulation may be required in certain situations. The inlet damper and insulated inlet piping will
prevent cold air migration and a slight incline will keep moisture collection at the inlet end.
