Packaging
Check for shipping damage. If any damage is found, document the damage
with the shipping agency and immediately contact your Distributor. If you are
an authorized Distributor, follow the FOB freight policy procedures provided by
Thomas & Betts for this product.
Because of their modular design, these heaters are packaged in sections and
require field assembly. The burner/control box is in one carton, and the tubes
are packaged in one, two, or three cartons depending on the length of the sys-
tem. Each shipped-separate option has its own carton. Be sure all parts are at
the site before beginning installation.
Burner/Control Box Carton - For the convenience of both the stocking and
the non-stocking distributor, Model VR burner/control boxes have two differ-
ent packaging schemes. Read carefully to determine whether or not the
burner/control box requires field conversion before being installed. Model
GVR burner/control box is available in specific sizes only.

(2) Burner/Control Box Factory Built to a Specific Size (Models VR & GVR)
- If the burner/control box carton does not have a label about field conver-
sion, the carton contains a burner/control box factory-built to a specific size.
Check the rating plate to verify size and type of gas.
Tube Cartons (Models VR & GVR) - Tubes are also packaged so that a mini-
mum number of cartons will cover all lengths of heater systems. This package
identification system applies to all heaters, whether shipped from distributor
stock or shipped to order from the factory. Before beginning installation, verify
that the packages at the job site match the length of heater being installed.
Reflectors, wire reflector retainers, hanger bars, tube brackets, compression
couplings, and hardware bags with required reflector and tube hardware are
included in each carton.
should be located parallel to the wall. The distance from the wall is determined
by whether the reflectors will be angled or horizontal.
For spot heating applications, the tubular system should be located to direct
the rays toward the area requiring heat. Depending on the installation, this
can be done from directly overhead or reflector angled from the side. U-tube
configurations are often best suited for overhead spot heating applications.
Refer to the recommended minimum mounting heights below. Use the mount-
ing height, the size of the heater, the heater configuration, and the application
conditions to determine the most efficient location of the heater.
