Unpacking 10 1. Visually check for any physical damage to the shipping container. 2. Inspect the equipment surfaces that are adjacent to any damaged area. 3. Open the furnace door and remove the packing material from inside the furnace chamber. 4. Vacuum the chamber prior to use to remove the insulation dust due to shipment. 5. Retain the original packaging material if reshipment is foreseen or required.
Installation Site Selection Caution Be sure ambient temperature does not exceed 40°C (104°F). The recommended ambient temperature is 17°C - 27°C. Ambients above this level may result in damage to the controller. Caution Allow at least six inches of space between the furnace and any combustible surface. This permits the heat from the furnace case to escape so as not to create a possible fire hazard. Install furnace on a sturdy surface and allow adequate space for ventilation.
Operation, All Models Warning To avoid personal injury do not use in the presence of flammable or combustible chemicals; fire or explosion may result. This device contains components which may ignite such materials. Power Switch Both the ON/OFF power switch and the digital display will illuminate when power is switched ON. The furnace will begin to heat to its controller's current setpoint. (See the instructions for your type of controller for information on checking and setting the setpoint.
