Caution
Be sure ambient temperature does
not exceed 104°F (40°C); ambients
above this level may result in dam-
age to the control.
Allow at least six inches of space
between the furnace and any com-
bustible surface. This permits the heat
from the furnace case to escape so as
not to create a possible fire hazard.
Note
Furnace comes with both 1" and 2"
dia. end caps. Install the end cap
which fits the tube you plan to use.
To avoid electrical shock, this furnace
must be installed by a competent, qual-
ified electrician who insures compatibili-
ty among furnace specification, power
source and ground code requirements.
Warning
Installation
SITE SELECTION: Install furnace on a sturdy sur-
face and allow space for ventilation.
The electrical specifications are located on the specifica-
tion plate on the back of the furnace. Consult Barn-
stead/Thermolyne if your electrical service is different
than those listed on the specification plate. Prior to con-
necting your Type 21100 furnace to your electrical sup-
ply, be sure the power or control switch is in the OFF
position.
