2. The overlap at the first and second reflector is a slip overlap.
Thereafter, every third reflector joint is a slip overlap. A slip
overlap is achieved by either:
a.) both reflectors lay inside a hanger.
(No reflector support needed.)
b.) using a reflector support with
loose screws at the reflector
overlap.
3. The remaining reflector overlaps require a non-slip
overlap connection. To affix the reflectors together in
a non-slip overlap either:
a.) use reflector support and tight screws.
b.) if both reflectors lay inside a hanger, u-clips or
sheet metal screws may be used.
This section of three reflectors joined together must
be affixed to the tube with at least one reflector support
with tight screws.

Step 6.5.1 Reflector, U-Clip and Reflector Support Installation
The pictorial drawings of the heater construction in
Section 6 are schematic only and provide a general
guideline of where hangers, reflector supports and
U-clips are to be installed.
To ensure proper expansion and contraction
movement of the reflectors, a combination of U-clips
and reflector supports are used. The positioning of
reflector supports and U-clips depend on the
individual installation. The following rules must be
observed.

Failure to follow these instructions can result
in injury.
SECTION 7: OPTIONAL HEATER ACCESSORIES
7.1 U-Tube Configuration
Heaters (except BH-40) are approved for optional
U-tube configurations.
The U-tube may be installed in either a standard
horizontal position, a 45° position or in an opposite
45° position as shown on Page 6, Figure 7 through
Page 7, Figure 9. When using a U-tube configuration,
the following additional rules must be adhered to:
• A minimum of 10' (3 m) on BH-60/80 and a
minimum of 15
150/175/200 is required between the burner and
the U-tube.
• The correct turbulator (See Page 20, Step 6.4)
must be installed in the last standard section of
the tube.
• The burner must never be operated in a tilted
position.
• The heater must be properly supported at all
locations. See Page 26, Figure 19.
