Be sure ambient temperature does not exceed 40°C (104°F). Ambients above this
level may result in damage to or malfunction of the controller. Allow at least 6 inches
of space between the furnace and a surface,and at least 40 inches above the furnace.
This permits the heat from furnace case to escape so as not to create a possible fire
hazard.
Do not install above or near flammables.

Site Selection
Place the furnace on a sturdy level surface about 26-28 inches high and capable of supporting the
weight of the fully assembled furnace. Furnace must be placed on a level surface to permit door to
safely swing and remain open for loading and unloading. Allow space for air flow around the furnace
(6" minimum). Locate the furnace so you can direct the furnace’s emissions through ducting to a fume
hood or other appropriate ventilation system. We recommend an exhaust length of not more than

10 feet, if possible. Leveling feet are adjustable. The furnace should be leveled so the door will remain
open.

Electrical Connections
The electrical specifications are:
Your furnace is factory configured for a 27 amp supply. You have the option of re-configuring the
wiring at the back of the furnace for 20 amps. Please see
“Amperage Configurations” on page 85 .
Typically, a 20 amp configuration is used for mobile laboratory installations or if your supply is only
rated for 20 amps.
Prior to connecting your asphalt testing furnace to your electrical supply, be sure the front power

switch and rear circuit breaker are in the OFF position.
The power supply entry is located at the right rear of the lower case (as you face the rear of the unit). A
terminal block is located behind an access plate. Remove the six screws retaining the plate covering the
To avoid electrical shock, this furnace must be installed by a competent, qualified
electrician who ensures compatibility among furnace specifications, power source and
ground code requirements.
For supply connections, use 10 AWG or larger wires suitable for at least 90°C. Failure
to observe this caution could result in damage to furnace and/or work area.
