Insert Manual

For complete installation instructions, reference the Tube Heater General Manual that accompanies this insert manual.

The DX2 Series Infra-Red 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 specic information

related to the DX2 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,

re 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 re department.

Keep these instructions for future reference.

Clearance to Combustibles

WARNING

Placement of explosive objects, ammable objects, liquids and vapors close to the heater may result in explosion, re, property damage, serious injury or death.

Do not store or use explosive objects, liquids or vapor in the vicinity of the heater.

Clearance to combustibles is dened as the minimum distance that must exist between the tube surface, or reector, 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 your series tube heater and

conguration must be maintained. Refer to Chart 1.1 on the following page to determine the required

distances for your model.

The stated clearance to combustibles represents a surface temperature of 90ºF (32ºC) above room temperature. Building materials with a low heat tolerance (such as plastics, vinyl siding, canvas, 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 ame 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 briey interrupting the power

source.

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

immediately acts to reignite the gas-air mixture (identical to the starting sequence). If ame 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 briey interrupting the power source.

Thermostat

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

specications for details.

NOTE: A relay transformer may be used in lieu of the factory installed 24VAO option.

physically

damaged?

Is the blower

obstructed?

Yes

Remove obstruction

and lubricate fan.

Is the inlet or the outlet of

the unit obstructed (i.e.,

ice, birds nest, dirt, etc.)?

Yes

Remove obstruction.

Check voltage at ignitor during

ignition sequence (usually 3045 seconds after power to the

heater). Is it 120V?

Yes

Does valve light

energize?

Yes

Does valve open?

Yes

Continued on page 16.

Yes

Replace ignitor.

Does the burner

ignite at all?

Yes

Replace faulty light.

Conﬁrm that gas pressure

is within minimum and

maximum inputs as

indicated on the burner

rating plate. Are they ok?

Replace circuit board.

The circuit board and/or wiring

harness may be faulty and

needs to be replaced.

Yes

Correct problem.

Replace gas valve.

NOTICE

Is 120V coming

to the fan?

Yes

The fan is faulty

and must be

replaced.

Check for loose wiring

or resistance in hose

connection to pressure

switch. Are they ok?

Bypassing any switch is intended for testing purposes only. Do not leave switch bypassed during normal operation or the heater’s built-in safety mechanisms will be compromised.

Key

Correct

wiring.

Yes

Start Question

The heater is equipped with a safety pressure

switch. This differential switch, located in

the valve compartment, is a normally open

pressure switch. Temporarily place jumpers

across the terminals of the switch (Be sure to

reinstall the burner control box cover).

Does the light energize?

Process Question

Corrective Action

Replace faulty light.

Yes

Repair.

Is resistance through

the ignitor 50-400 Ω ?

Replace

ignitor.

Yes

Consult

factory.

Replace the differential switch after verifying the following:

• Bafe(s) is/are in the radiant tube(s) farthest from the burner.

• 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.

DX2 Series

After ignitor is

warmed up, does

gas valve open?

Yes

Does the

burner ignite?

Yes

Does the burner

stay on?

Yes

Test for 120V at valve opening period (usually 30 to 45 seconds

after power to heater). Is there 120V to valve for 8 seconds?

Replace circuit board and/or wiring harness.

Is the gas supply

to the heater in

the ON position?

Yes

Turn on.

Does the burner stay on

for approx. 8 seconds

and then shut off?

Check to make sure gas pressure is within

minimum and maximum inputs, as indicated on

burner rating plate. Is gas pressure OK?

Correct problem.

Does the burner come

on and turn off

immediately (1 or 2

seconds)?

Yes

Check to make sure gas pressure

is within minimum and maximum inputs, as indicated on the burner rating plate. Is gas pressure OK?

Yes

Pressure switch may be faulty or

there is a

restriction in the exhaust.

Does the heater

stay ON until a call

for heat ends?

Yes

Troubleshooting ends

The heater can shut down due to:

• Improper grounding.

• High winds.

• Taking combustion air from the attic.

• Dirty environment.

• Improperly positioned bafes.

• Fluctuating gas pressure.

Correct problem.

Check to make sure gas pressure is within minimum and

maximum inputs, as indicated on burner rating plate.

Is gas pressure OK?

Correct problem.

Yes

4.0 Troubleshooting Guide

Replace gas valve.

Were the gas lines purged of air?

Purge gas line.

Is the heater properly

grounded? Is the heater’s

polarity correct?

Correct problem.

Yes

Conrm manifold pressure is

correct and/or gas orice is not

plugged and is the correct size.

With micrometer, check

Yes Yes

amperage at ame rod. Is it

greater than .7 microamps?

Sensing rod is faulty or ame

is weak. Check to make sure

heater is operating at proper

gas pressure as indicated on

burner rating plate and then, if

needed, replace sensing rod.

Check to make sure ame

sensor wire is OK. If so,

then replace circuit board.
