■ 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.

■ Natural gas is lighter than air and can collect around

rafters or ceilings.

■ Use your neighbor’s phone and call your fuel gas

supplier and your fire department. Do not re-enter the
building or area.

■ Stay out of the building and away from the area until

declared safe by the firefighters and your fuel gas

supplier.

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 confinement buildings can mask fuel gas odor.

ATTENTION -- CRITICAL POINTS TO REMEMBER!

■ 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 “snif f 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 amou nt of gas, CONTACT YOUR FUEL G AS

6. Insure that all accessories that ship with the heater
have been removed from inside of heater’s shipping
container and installed. This pertains to gas hose,
regulators, etc.

7. The heater’s gas regulator (with pressure relief valve)
should be installed outside of building. Typically any
regulators inside the buildings must be properly
vented to the outside. However, local, state and
national codes always apply to regulator installation.

15. Turn off the gas supply when the heater is not in use.

8. Any reg u l a tor mounted outside the building be
pro tec ted ag a i n st the weather, pa r ticula r l y i c e
fo rm a ti o n. Ic e fo rm a ti o n can le a d to
overpressurization of the regulator and subsequent
gas leaks. See codes covering proper protection.

9. Always use pipe joint compound that is resistant to

liquefied petroleum gas and natural gas.

10. Check all connections for gas leaks using approved
gas leak detectors. Gas leak testing is performed as
follows:

WWAARRNNIINNGG

FFiirree aanndd EExxpplloossiioonn HHaazzaarrdd

■ Do not use open flame (matches, torches, candles,

etc.) in checking for gas leaks.

■ Use only approved leak detectors.

■ Failure to follow this warning can lead to fires or

explosions.

■ Fires or explosions can lead to property damage, injury

or death.

-- Check all pipe connections, hose connections,
fittings and adapters upstream of the gas
control with approved gas leak detectors.

-- In the event a gas leak is detected, check the
co mponents involved for cle anliness a nd
proper application of pipe compound before
further tightening.

-- Furthermore tighten the gas connections as
necessary to stop the leak.

FUNCTION AND INSTALLATION

(Optional)

With proper (5 PSIG) gas pressure supplied, spark ignition
heaters will operate in the standard ON/OFF mode when
electrically connected to a building environment controller or
thermostat

If you require two stages of heat for greater temperature
control, a two stage solenoid operated zone panel must be
installed. This panel incorporates solenoids to control the
first and second stage heating levels as well as a pressure
regulator to set the firing rate of the first stage. Use of this
panel requi r e s a t w o s t age therm o s t at or a buildi n g
controller capable of controlling the heat in two stages.

When energized by a building controller or thermostat, the
zone panel’s first stage solenoid opens providing 2 PSIG,
controlled by the regulator on the zone control panel, to the
heater. This represents approximately half the heater’s full
output. If this level of heating does not satisfy the demand,
the building controller or thermostat will call for the second
stage of heating, full output, by energizing the second stage
solenoid. This provides 5 PSIG to the heater.

As the heat demand is satisfied, the building controller or
thermostat will reduce the firing rate by closing the second
stage solenoid and lastly the first stage solenoid if heat is no
longer needed.

Two stage zone panels are available in high or medium
capacity configurations and will control the following quantity
of heaters depending on fuel type.

Solenoid Zone Control System

Medium High

Model and Capacity Capacity

Heat Output Fuel Panel Panel

Quantity Quantity

I34 L. P. Gas 7 20

(34,200 BTUH) Natural Gas 4 20

All zone control pan els mus t have an adjustabl e high
pressure regulator installed upstream of the inlet of the
panel. This regulator may be purchased from PSI as an
optional accessory. The regulator must be capable of
handli n g a m aximum i n l et press u r e of 10 p si, whil e
supplying an outlet pressure of 5 psi nominal.

Separate installation instructions accompany each zone
panel.

IMPORTANT

This filter kit is designed to provide additional dust filtration
capability and capacity for Infraconic heaters when installed
in severely dusty environments.

1. Attach filter sleeve to injector body. The injector body
tabs fit into the slots on the sleeve. Rotate the sleeve
to lock it onto the injector body.

2. Position the filter onto the sleeve. Ensure all sleeve
holes are covered by the filter.

Follow steps 1-5 on initial start up after heater installation
by a qualified gas heater service person. For normal
startup, simply turn the building thermostat above room
temperature.

1. Connect the heater to an approved electrical supply
and building’s temperature control system.

2. Open all gas supply valves to the heater and check
for gas leaks at all connections using approved leak
detectors.

3. Energize the building’s temperature control system to
provide power to the heater.

4. Position the ON/OFF switch on the heater’s control
box to ON. See Fig. 7. The igniter will spark and
ignition will occur.

5. Set the building’s temperature control to desired
temperature.

■ It is normal for air to be trapped in the gas line on new

installations.

■ The heater may attempt more than one ignition trial

before air is purged from the line and ignition occurs.

purposes of controlling the timing of the ignition process of
the heater as well as monitoring the safety functions. The
control module is located in a control box at the gas inlet
end of the heater. On a call for heat, the igniter will spark
and the gas control valve will open shortly afterward. The
igniter will continue to spark for approximately 10 seconds.
Flame sense, as monitored by the ignition control, will keep
the gas valve open and main burner in operation until
proper temperature is achieved.

The ignition control module will make up to 3 trials for
ignition. There will be a 15 second time span between each
ignition trial. If ignition is not achieved after the third trial, a
15 minute wait period will occur. After the 15 minute time
span has elapsed, the heater will make three more trials for
ignition. This process will continue as long as there is a call
for heat from the building’s temperature control system.

-- Ignition control sends high voltage to igniter
electrode

-- Igniter sparks

-- Gas control solenoid opens

••

Ignition occurs

-- Igniter continues to spark for 10 seconds until
flame proving occurs

-- Ignition spark is shut off

-- Gas control solenoid stays open

••

Ground warms to desired temperature

-- Building thermostat is satisfied

-- Heater shuts down

••

Process is repeated on a call for heat

IGNITION FAILURE SEQUENCE:

••

Ignition control will make three ignition trials

-- Each trial lasts 10 seconds

-- 15 seconds time span between each trial

••

If ignition control does not establish flame sense within

ignition trial:

-- Ignition spark shuts off

-- Gas valve closes

••

After three ignition trials, ignition control will wait for 15

minutes before retrying for ignition.

••

This process will be repeated continually until the

ignition problem is solved.

••

To manually reset the ignition control:

-- Unplug the heater and plug it back in

OR

Heater Component Function

Burner Orifice

Metering device used to feed gas to combustion cones at a
specific flow rate.

Canopy

Reflective aluminum heat shield for heater.

Double Combustion Chamber

Made of special alloy steel. This is where combustion of gas
occurs, providing radiant heat used in the warming process.
Consists of small inner cone and large outer cone

Gas Control Valve

Component that houses electromagnet which is energized by
voltage and therefore opens or closes to supply or shut off
the flow of gas to the burner.

Gas Hose

Flexible connector used to convey gas from gas supply line
to inlet of heater.

High Limit Switch

Safety device wired into the heater’s electrical supply which
is used to open the electrical circuit to the ignition control
module in the event of an overheat condition.

Igniter/Sensor

Electrical ignition device used on automatic ignition control
systems. Ignites gas by spark. The igniter also serves as a
flame sensor on this heater to prove flame after ignition

Ignition Control Module

Electronic device which controls the ignition sequence and
operation of the heater.

Injector Body

Allows combustion air to be drawn in to injector tube with
gas flow for combustion.

Manual Shut Off Valve

It’s purpose is to shut off gas flow to the appliance if
maintenance or service are required, or if an emergency
situation occurs. When the handle on the manual valve is
turned parallel to gas flow, the valve is completely open
delivering full gas supply to the appliance. Turning handle
perpendicular (90°) to gas flow shuts off gas flow.

On/Off Switch

Simple electrical device used to connect or disconnect
incoming voltage at the ignition control box on the heater.

Venturi Tube

Tubular steel neck connecting the gas control valve and
burner orifices to the combustion cones. Gas is fed to the
combustion cones through the injector tube.
