Totally Exposed Outdoor Applications; Lamp Installation & Replacement - Fostoria 222 Series Manual

For totally exposed outdoor applications (not
ceiling protected) the connections must be made
as illustrated at right.
Red sleeves used for visible light reduction are
not recommended for applications near coastal
waters. Purchase lamps with integral light filter
from factory for these applications.
CAUTION: Disconnect power before installing
or replacing supplied quartz lamps or quartz
tubes. These elements can and should be
installed prior to mounting heater.
1. Remove the housing end caps and open
positioning clips.
2. Position heating elements in "L" slots at ends of
reflector. Avoid handling quartz glass as much
as practical. Quartz glass should be wiped off
with a clean cloth before energizing heater.
3. Close positioning clips to secure the heating
element in the slot (see figure A).
4. Carefully wrap heating element pigtail clockwise
around terminal screws (see figure B).
5. Tighten terminal screws (see figure B).
CAUTION: Do not draw pigtail so tight
that pressure is put on heating element.
Maintain a partial loop (or looseness) in the
pigtail 1/2" max. see FIGURE B.
NOTE: Cut excess pigtail off at terminal to
prevent lead from touching metal parts.
6. Install end caps using sheet metal screws
supplied in parts kit.
Note: The Mul-T-Mount heaters are designed for
use with Fostoria quartz lamp infrared heating
elements only. They are NOT intended to be
used with straight metal rod heating elements.

POSSIBLE LAMP FAILURE
The heating elements used in this product can be damaged
by contamination (salt deposits from perspiration or
coastal air) on the surface of the quartz sleeve. At high
temperatures, these salts will cause the quartz to become
porous and leak, allowing air to come in contact with the
tungsten element. When this occurs, the element will burn
out quickly and the outer quartz sleeve can break. The
instructions below must be followed.
• Always wear cotton or latex gloves when installing or
replacing elements.
• Always clean the quartz sleeve with an alcohol
moistened soft cloth before using the heater
• Whenever contamination (milky white appearance
on quartz sleeve) is observed, the element must be
immediately replaced
