Propane gas and natural gas have man-made odorants added specifi cally for detection of fuel gas leaks.
If a gas leak occurs, you should be able to smell the
fuel gas .
THAT’S YOUR SIGNAL TO GO INTO IMMEDIATE
ACTION!
■ Do not take any action that could ignite the fuel
gas. Do not operate any electrical switches. Do not
pull any power supply or extension cords. Do not
light matches or any other source of fl ame. Do not
use your telephone.
■ Get everyone out of the building and away from the
area immediately.
■ Close all propane gas tank or cylinder fuel supply
valves, or the main fuel supply valve located at the
meter if you use natural gas.
■ Propane gas is heavier than air and may settle in
low areas. When you have reason to suspect a
propane leak, keep out of all low areas.
■ Use your neighbor’s phone and call your fuel gas-
supplier and your fi re department. Do not re-enter
the building or area.
■ Stay out of the building and away from the area
until declared safe by the fi refi ghters and your fuel
gas supplier.
■ FINALLY, let the fuel gas service person and the
fi refi ghters check for escaped gas. Have them
air out the building and area before you return.
Properly trained service people must repair the
leak, check for further leakages, and then relight
the appliance for you.
■ Some people cannot smell well. Some people
cannot smell the odor of the man-made chemical added to propane or natural gas. You must
determine if you can smell the odorant in these
fuel gases.
■ Learn to recognize the odor of propane gas and
natural gas. Local propane gas dealers and your
local natural gas supplier (utility) will be more than
happy to give you a “scratch and sniff” pamphlet.
Use it to become familiar with the fuel gas odor.
■ Smoking can decrease your ability to smell. Being
around an odor for a period of time can affect your
sensitivity to that particular odor. Odors present in
animal confi nement buildings can mask fuel gas
odor.
■ The odorant in propane gas and natural gas is col-
orless and the intensity of its odor can fade under
some circumstances.
■ If there is an underground leak, the movement of
gas through the soil can fi lter the odorant.
■ Propane gas odor may differ in intensity at different
levels. Since propane gas is heavier than air, there
may be more odor at lower levels.
■ Always be sensitive to the slightest gas odor. If you
continue to detect any gas odor, no matter how
small, treat it as a serious leak. Immediately go into
action as discussed previously.

■ Propane gas and natural gas have a distinctive
odor. Learn to recognize these odors. (Reference
“Fuel Gas Odor” and “Odor Fading” sections
above.
■ If you have not been properly trained in repair and
service of propane gas and natural gas fueled
heaters, then do not attempt to light the heater, perform service or repairs, or make any adjustments
to the heater on a propane (LP) gas or natural gas
fuel system.
■ Even if you are not properly trained in the service
and repair of radiant heaters, ALWAYS be consciously aware of the odors of propane gas and
natural gas.
■ A periodic “sniff test” around the heater or at the
heater’s joints; i.e. hose, connections, etc., is a
good safety practice under any conditions. If you
smell even a small amount of gas, CONTACT
YOUR FUEL GAS SUPPLIER IMMEDIATELY.

installed outside the building.
-- Regulators installed inside should be vented outside.
-- Local state and national codes apply to regulator in-
stallation. Refer to NFPA 54, National Fuel Gas Code,
and NFPA 58, Standard for Storage and Handling of
Liquifi ed Petroleum Gas.
8. Always use pipe joint compound that is resistant to
liquefi ed petroleum gas and natural gas.
9. Check all connections for gas leaks using approved
gas leak detectors. Gas leak testing is performed as
follows:
-- Check all pipe connections, hose connections, fi ttings
and adapters upstream of the gas control with approved gas leak detectors.
-- In the event a gas leak is detected, check the compo-
nents involved for cleanliness and proper application of
pipe compound before further tightening.
-- Tighten the gas connections as necessary to stop the

Heater Controls
Refer to the heater’s burner box hinged access panel, or
refer to Start-up instructions in this manual to determine if
your heater has a single or two stage gas control.
The tube heater is operated by the building’s environmental control system. To accomplish this, the heater must be
connected to an electrical outlet controlled by a relay or
set of contacts that is closed and opened by the building
controller.
A series tap thermostat may be used to operate the tube
heater.
Connecting a Series Tap
Thermostat
-- Connect the power cord of the heater to the female side
of the thermostat cord set.
-- Plug the male side of the thermostat cord to an approved extension cord or to a wall outlet.
Start-Up Instructions
Follow steps 1 - 6 on initial start-up after heater installation. For normal start-up, set building control thermostat
above room temperature. The heater will start.
1. Open all manual fuel supply valves and check for gas
leaks using approved leak detectors. The gas control
valve has a manual shut-off feature incorporated into
the valve assembly. Ensure the indicator on the valve
is turned to the ON position. See Fig. 14.
WARNING
Electrical Shock Hazard
■ Disconnect the heater’s electrical supply before
interconnecting the temperature control.
■ Failure to disconnect the electrical supply will
result in electrical shock.

Air diff erential switch:
The air differential switch is a normally open, critical
safety device. See Fig. 23 for location. Its purpose is
to prove to the ignition control that there is a suffi cient
difference in pressure within the burner box before the
ignition control sends power to open the gas control
valve.
FIG. 23
Its electrical contacts close based on the difference
between pressures between the air inlet and the burner
box compartment. If the switch does not close after the
fan motor starts, the igniter will not spark nor will the gas
control valve open. A rapid fl ash will occur on the red
fault diagnostic light. The ignition control will lock-out
for 60 seconds before another trial attempt. After three
(3) fail attempts, a 2-time fl ash pattern will occur. The
same will occur if the fan motor does not start on a call
for heat.
If the switch is already closed from a past ignition trial,
and stays closed prior to a call for heat, the fan motor
will not start, nor will the igniter spark or the valve open.
A rapid fl ash will occur on the red fault diagnostic light.
The ignition control will lock-out for 60 seconds before
another trial attempt. After three (3) failed attempts, a
1-fl ash pattern will occur.
The air differential switch orifi ces should be free of dirt.
If cleaning is needed, use pressurized air. See picture
below.
• Remove the respective orifi ce from the switch.
• Hold up to light. If blocked, clean with air.
• Ensure the orifi ces are pushed back into the proper
location on the switch.
• Green orifi ce into black stem
• Blue orifi ce into white stem on switch.
To test the switch:
• Disconnect the pressure switch wiring at terminals PSI
and PSO of the ignition control.
• Route the wires so both are exterior of the burner box
when the burner box’ access door is closed and latched.
• Start the heater. As soon as the fan motor starts, connect both air switch leads together.
• If the heater starts and operates normally, verify the
following:
o Pressure switch wire terminals at the ignition control
are tight and in good condition.
o No obstructions at air inlet

Transformer
The transformer (Fig. 27) reduces the main power supply voltage to 24 VAC. The 24 VAC is sent to the ignition
controller. Once the ignition controller receives 24 VAC,
an ignition cycle begins.
If the transformer is receiving main power voltage, but
24 VAC is absent from its output terminals, the transformer is defective. The heater will not operate, nor will
the green LED on the burner box side be on.
