Insert Manual

For complete installation instructions, see the General Manual
that accompanies this insert.

The XTS3 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 XTS3 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.

!

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.

For Your Safety

If you smell gas:

• 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.

Keep these instructions for future reference.

AVOID EQUIPMENT FAILURE

THIS 10 FT. TUBE IS THE

COMBUSTION CHAMBER.

The combustion chamber utilizes either 409

stainless, titanium alloy or aluminized steel -

depending on the model number of your heater.

THIS TUBE MUST BE THE FIRST TUBE

FOLLOWING THE BURNER CONTROL BOX.

Rotate the tube’s welded seam to bottom.

Consult the manual(s) for further details.

!

WARNING

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 and vapor in the vicinity of
the heater.

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 Series tube heater and
configuration must be maintained. Refer to Chart 1.1 on the following page to determine the required
distances for your model.

tri-ply, etc.) may be subject to degradation at lower temperatures. It is the installer’s responsibility to
assure that adjacent materials are protected from degradation.

3.0 Operation

!

WARNING

This heater must be installed and serviced by trained gas installation and service
personnel only.

Do not bypass any safety features or the heater’s built in safety mechanisms will be
compromised.

NOTE: Reference the Tube Heater General Manual for installation requirements.

Sequence of Operation

Starting Circuit: Upon a call for heat, the fan is energized. Once operational static pressure is achieved,

the differential switch will close initiating the ignition sequence. After a 5-second delay, the glo-bar is
energized for 45 seconds and the control allows the gas valve to open.

The trial for ignition is 8 seconds. If flame sense is not established within 8.5 seconds, the heater will

attempt two (2) additional ignition sequences before proceeding to soft lockout. Soft lockout
automatically retries after one (1) hour or the control can be reset by briefly interrupting the power
source.

Running Circuit: After ignition, the flame rod monitors burner flame. If sense of flame is lost, the control

immediately acts to reignite the gas-air mixture (identical to the starting sequence). If flame sense is
not established within 8.5 seconds, the heater will attempt two (2) additional ignition sequences
before proceeding to soft lockout. The control can be reset by briefly interrupting the power source.

Thermostat

NOTE: Different thermostats operate according to their particular features. Refer to thermostat

specifications for details. Refer to Figure 2.1 for field wiring diagrams.

XTS3 Series heaters with 24VAO option require a 24V, single-stage thermostat to operate. The burner
control box is equipped with a round terminal strip that accepts two (2) 1/4” female spade terminals. Do
not supply 120V to the 24V connection.

• The heater, fan blower, squirrel cage, intake and exhaust are free from

dirt and obstructions.

• The 4” air intake pipe does not exceed 20 feet and/or 2 elbows.

• There is not a negative pressure experienced at the area of air intake

(i.e., attic space, high winds, very tight building).

If any of the above are occurring, please address the problem.
