The DX3 Series Infrared Tube Heater is a positive pressure, single-stage radiant heater system. This
insert manual is a supplement to the Tube Heater General Manual and provides specific information
related to the DX3 Series model. All persons involved with the installation, operation and maintenance of
the heater system must read and understand the information in this insert manual and the accompanying
Tube Heater General Manual.

For Your Safety

If you smell gas:

WARNING

Improper installation, adjustment, alteration, service or maintenance can cause
property damage, injury or death. Read the installation, operation and maintenance
instructions thoroughly before installing or servicing this equipment.

This heater must be installed and serviced by trained gas installation and service
personnel only. Failure to comply could result in personal injury, asphyxiation, death,
fire or property damage.

In locations used for the storage of combustible materials, signs must be posted to
specify the maximum permissible stacking height to maintain the required clearances
from the heater to the combustibles. Signs must either be posted adjacent to the
heater thermostats or in the absence of such thermostats, in a conspicuous location.

Not for residential use! Do not use this heater in the home, sleeping quarters,
attached garages, etc. Installation of a commercial tube heater system in residential
indoor spaces may result in property damage, serious injury, asphyxiation or death.

• Do not try to light any appliance. • Immediately call your gas supplier from a neighbor’s phone.

• Do not touch any electrical switch. • Follow the gas supplier’s instructions.

• Do not use any phone in your building. • If you cannot reach your gas supplier, call the fire department.

INSTALLER: Present this manual to the end user.

Keep these instructions in a clean and dry place for future reference.

WARNING

Radiant Tube (s)

Clearance to combustibles is defined as the minimum distance that must exist between the tube surface,
or reflector, and any combustible items (see Figure 1.1). It also pertains to the distance that must be
maintained from moving objects around the tube heater. When installing the tube heater system, clearances
to combustibles for the model tube heater and configuration must be maintained. Refer to Chart 1.1 to
determine the required distances for your model.

Placement of explosive objects, flammable objects, liquids and vapors close to
the heater may result in explosion, fire, property damage, serious injury or death.
Do not store or use explosive objects, liquids or vapor in the vicinity of the heater.
