SYSTEM INSTALLATION
WARNING
COLLAPSE, FIRE AND EXPLOSION HAZARD
Improper suspension of the tube heater may
result in collapse and being crushed. Always
suspend from a permanent and secure part of
the building structure that can evenly support
the total force and weight of entire the heating
system.
Failure to maintain minimum clearance to
combustibles may result in fire and/or explosion,
property damage, serious injury or death.
Always maintain minimum clearances and post
clearance signs where needed.
Combustion Research Corporation recommends that
Reflect-O-Ray
®
EDS-4DI & EHS-4DI
systems are hung by
means of chain.
DO NOT
STRETCH OR INSTALL CHAIN
OTHER THAN IN A VERTICAL FASHION WHEN
INITIALLY INSTALLED (BURNER NOT FIRING).
WARNING
DO NOT SUSPEND 1/4 HP AND LARGER
VACUUM EXHAUSTER BY CHAIN - USE
THREADED ROD, ANGLE IRON, ETC.
If chain is not supplied by Combustion Research
Corporation, furnish a chain with a minimum 90 lb. workload
(trade size #3 or larger).
CAUTION
:
This infrared tube system will expand and
contract upon each call for heat and allowances must be
made to accommodate this expansion.
Provisions must be made to limit lateral movement when
systems are installed in site conditions where open doors
may create a wind condition. See page 10 for details.
SUSPENSION COMPONENTS - Sub Assembly and
Installation
1. Using the system layout, beginning at the vacuum
exhauster position, determine location of suspension
points of system in relation to building structure, paying
close attention to dimensional limits as shown on page 8.
2. Determine suspension requirements for chain, wire rope,
beam clamps, etc. with the type of mounting hardware as
illustrated. Secure appropriate of each item before
starting installation. Suspension hardware may not be
furnished with this system.
3. If any suspension supports are to be anchored in
cement, drill and insert Acherman-Johnson stud anchors
(or equivalent) as required. DO NOT install anchors in
existing cracks or joints.
4. Determine suspension chain lengths and proceed to cut
and pre assemble suspension components.
NOTE:
Each
Reflect-O-Ray
®
EDS-4DI & EHS-4DI
burner
assembly is equipped with a suspension point. Adjust as
required to keep the burner assembly level and square to
the radiant tubing.
5. Install beam clamps, eyebolts, etc. at predetermined
suspension locations - refer to the installation layout and
the illustration on page 10 of this manual for guidance.
IMPORTANT NOTE:
If wind or sever air movement can be
encountered in the building (such as found in airplane
hangers where opposing doors are simultaneously open) or
if your area is prone to seismic activity, additional support of
the radiant tube and reflector network will be required. See
page 11 for details
RADIANT TUBE INSTALLATION
The
Reflect-O-Ray
®
EDS-4DI & EHS-4DI
radiant heating
system is sealed system. Therefore the heat radiant tubing
installation must be adhered to as outlined in this manual for
optimum performance as designed.
RECOMMENDED HANGER LOCATIONS
For 40K to 175K input systems, the first 10' section of
radiant tube (0404.AS.16 or 0404.16.HT) after the burner
should be supported and hung with 3 combination hangers.
For 180K to 250K input systems, the first 20' of radiant tube
(0404.AT.16 & 0404.16.AS) after the burner should be
supported and hung with 5 combination hangers
NOTE – THE WELD SEAM ON THIS FIRST (AND
SECOND IF PROVIDED) SECTION OF TUBE MUST BE
POSITIONED SO THAT IT IS ON THE BOTTOM OF THE
TUBE WHEN INSTALLED
.
Weld Seam
Position
Bottom of Tube
Burner Tube End View
The first hanger should be located approximately 5" from the
burner and the next two combination hangers shall be hung
on approximately 56" centers. The rest of the system
combination hangers may be hung on approximately 9'-10"'
centers with intermediate reflector supports placed halfway
between hangers. Each reflector should be supported at
two points, either with two combination hangers or with one
combination hanger and an intermediate support
NOTE: When a vertical rise of tube is necessary, use a
combination hanger (P.N. 0464.00) at both the lower
horizontal run hanger and at the upper horizontal run. If the
vertical run exceeds ten feet (10') a midway support must be
installed. This support may be secured to a wall, beam or
fabricated support. It is recommended that the vertical run
not exceed twenty-five feet (25').
