Safety Precautions

WARNING

Asphyxiation Hazard

■

Do not use this heater for heating human living quarters.

L.B. White Company to determine combustion air ventilation requirements of the heater.

■

Do not use in unventilated areas.

■

The flow of combustion and ventilation air must not be obstructed.

■

Proper ventilation air must be provided to support the combustion air requirements of the heater being used.

■

Refer to the specification section of the heater’s

Owner’s Manual, heater dataplate, or contact the

■

Lack of proper ventilation air will lead to improper combustion.

■

Improper combustion can lead to carbon monoxide poisoning in humans leading to serious injury or death.

Symptoms of carbon monoxide poisoning can include headaches, dizziness and difficulty in breathing.

■

Symptoms of improper combustion affecting livestock can be disease, lower feed conversion, or death.

FUEL GAS ODOR

LP gas and natural gas have man-made odorants added specifically 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 o r a ny ot h e r s o u rc e o f f l a m e . D o n ot u s e yo u r telephone.

■

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.

■

Get everyone out of the building and away from the area immediately.

■

Close all propane (LP) gas tank or cylinder fuel supply valves, or the main fuel supply valve located at the meter if you use natural gas.

■

Stay out of the building and away from the area until declared safe by the firefighters and your fuel gas supplier.

■

Propane (LP) 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.

■

FINALLY, let the fuel gas ser vice person and the firefighters 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.

ODOR FADING -- NO ODOR DETECTED

■

Some people cannot smell well. Some people cannot smell the odor of the man-made chemical added to propane (LP) or natural gas. You must determine if you can smell the odorant in these fuel gases.

■

Learn to recognize the odor of propane (LP) gas and natural gas. Local propane (LP) 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 confinement buildings can mask fuel gas odor.

■

The odorant in propane (LP) gas and natural gas is colorless 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 filter the odorant.

■

Propane (LP) gas odor may differ in intensity at different levels. Since propane (LP) 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.

ATTENTION -- CRITICAL POINTS TO REMEMBER!

■

Propane (LP) gas and natural gas have a distinctive odor. Learn to recognize these odors. (Reference Fuel

Gas Odor and Odor Fading sections above.

■

Even if you are not properly trained in the service and repair of the heater, ALWAYS be consciously aware of the odors of propane (LP) gas and natural gas.

■

If you have not been properly trained in repair and service of propane (LP) gas and natural gas fueled heaters, then do not attempt to light heater, perform service or repairs, or make any adjustments to the heater on propane (LP) gas or natural gas fuel system.

5

■

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. DO NOT WAIT!

Installation Instructions

GENERAL

WARNING

Fire or explosion hazard.

Can cause property damage, severe injury or death.

1. Disconnect power supply before wiring to prevent electrical shock or equipment damage.

2. To avoid dangerous accumulation of fuel gas, turn off gas supply at the appliance service valve before starting installation, and perform gas leak test after completion of installation.

3. Do not force the gas control knob. Use only your hand to turn the gas control knob. Never use any tools. If the knob will not operate by hand, the control should be replaced by a qualified service technician. Force or attempted repair may result in fire or explosion.

1.

Read all safety precautions and follow L. B. White recommendations when installing this heater. If during the installation or relocating of heater, you suspect that a part is damaged or defective, call a qualified service agency for repair or replacement.

2.

Make sure the heater is properly positioned before use and is hung level. Observe and obey all minimum safe distances of the heater to the nearest combustible materials. Minimum safe distances are given on the heater nameplate and on page 4 of this manual.

3.

For heaters intended for outdoor installation, the heater is to be installed at least 18 inches above the ground or to a height that would prevent snow blockage of heater’s air inlet.

4.

The heater may be used either indoors or outdoors.

When the heater is mounted outdoors, use only the ductwork supplied in the outdoor mounting kit.

5. The heater must have the proper gas regulator installed for the application. A regulator must be connected to the gas supply so that gas pressure at the inlet to the gas valve is regulated within the range specified on the dataplate at all times. Contact your gas supplier, or the

L.B. White Co., Inc. if you have any questions.

6.

The heater’s gas regulator (with pressure relief valve) s h o u l d b e i n s t a l l e d o u t s i d e o f b u i l d i n g . A ny regulators inside the buildings must be properly vented to the outside. Local, state and national codes always apply to regulator installation. Natural gas regulators with vent limiting device may be mounted indoors without venting to outdoors.

7.

All gas pressure regulators must be installed in strict accordance with the manufacturer’s safety instructions.

These instructions accompany each regulator.

7

8.

Insure that all accessories that ship within the heater have been removed from inside of heater and installed. This per tains to air diver ters, hose, regulators, etc.

9.

Make certain that a sediment trap is installed at the gas valve inlet to prevent foreign materials (pipe compound, pipe chips and scale) from entering the gas valve. Debris blown into the gas valve may cause that valve to malfunction resulting in a serious gas leak that could result in a possible fire or explosion causing loss of products, building or even life. A properly installed sediment trap will keep foreign materials from entering the gas valve and protect the safe functioning of that important safety component.

10.

Any heater connected to a piping system must have an accessible, approved manual shut of f valve installed within six feet (6 ft.) of the appliance it serves.

11.

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

WARNING

Fire and Explosion Hazard

■

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, personal injury or loss of life.

-- 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 components involved for cleanliness and proper application of pipe compound before further tightening.

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

-- After all connections are checked and any leaks are stopped, turn on the main burner.

-- Stand clear while the main burner ignites to prevent injury caused from hidden leaks that could cause flashback.

-- With the main burner in operation, check all connections, hose connections, fittings and joints as well as the gas control valve inlet and outlet connections with approved gas leak detectors.

-- If a leak is detected, check the components involved for cleanliness in the thread areas and proper application of pipe compound before further tightening.

-- Tighten the gas connection as necessary to stop the leak.

-- If necessary, replace the parts or components involved if the leak cannot be stopped.

-- Ensure all gas leaks have been identified and repaired before proceeding.

12.

2.

Connect the electrical cord to an approved electrical outlet.

3.

Set the thermostat (if supplied) to desired room temperature.

4.

This heater includes a direct ignition control module for purposes of controlling the timing of the ignition process of the heater as well as monitoring of the safety functions. The control module is contained within the control enclosure. On the control module is a red light emitting diode (LED). This LED indicates the status of the heater. The LED is visible external of the control enclosure through the plastic eye. A constant light from the LED is an indicator that the heater is functioning correctly. Any flash pattern by the LED is indicative that there is a problem in the operation of the heater. Refer to the troubleshooting decal on the access panel at the fan motor end of the heater for assistance in troubleshooting. Only qualified and properly trained personnel shall service or repair the heater.

5.

On a call for heat, the motor will start up and run for five seconds. This pre-purge is a safety feature and a normal operational characteristic prior to ignition taking place. After five seconds, the igniter will begin to spark.

NOTE: It is normal for air to be trapped in the gas hose on new installations. The heater may attempt more than one trial for ignition before the air is finally purged from the line and ignition takes place.

6.

The ignition control will make up to three trials for ignition. Each trial for ignition will take approximately ten (10) seconds. The first three trials for ignition will occur within 40 seconds if ignition is not achieved. A

15 minute “wait period” will then begin after the third trial for ignition has taken place. After the 15 minute time span has elapsed, three more trials for ignition will take place. If ignition is not achieved at this final trial, the system will lock out and a three flash pattern will be indicated by the LED.

Shut-Down Instructions

If the heater is to be shut down for cleaning, maintenance or repair, follow steps 1 - 5. Otherwise, simply turn thermostat to “off” or “no heat” for standard shut down.

1.

Close all manual fuel supply valves.

2.

With the heater lit, allow heater to burn off excess fuel in gas supply hose.

3.

Turn the indicator on the gas control to “off”.

4.

Turn thermostat to “off” or “no heat” position.

5.

Heater Component Function

Air Proving Switch

Safety device used to insure that the proper air flow is being achieved before the gas valve is opened.

Burner

Cast iron component used to channel gas and provide an area at which the fuel may ignite.

Igniter/Flame Sensor Assembly

This assembly consists of two components mounted adjacent on the same bracket.

-- Spark Igniter: Electrical ignition device used on automatic ignition control systems. Ignites gas by a spark.

-- Flame Sensor: Also known as a flame rod or flame probe, this device works in conjunction with the ignition module in proving that burner flame has been established.

Burner Orifice

Brass metering device used to feed gas to burner at a specific rate.

Fan Housing

Chamber used for compressing air for efficient air movement.

Fan Wheel

Component used in conjunction with the motor and fan housing to pull the hot air from heater and blow it into room for heating (also known as a “squirrel cage”).

Motor

Electric device used to force preheated air through the heater and to circulate heat within a cer tain area. Conver ts electrical energy into mechanical energy.

Regulator

The heart of any gas supply installation. Used to deliver a working pressure to the appliance under varying conditions in tank pressure.

Gas Control Valve

A device which consists of a low pressure regulator and electrical solenoids which are used for the control of gas flow to the burner assembly. A feature of the control is a built in gas shut off which is used to isolate the heater from its gas supply when servicing.

Thermostat

Electrical device used as an automatic “on/off” switch which will respond to changes in temperature in a certain area. Can be wired so contacts in the thermostat open or close on temperature increase or decrease.

Gas Hose

Flexible connector used to convey gas from supply line in building to heater.

Throttle Valve

Manually adjustable component used to increase or decrease the flow of gas to the burner. The throttle valve is located between the gas control valve and burner assembly.

Heat Chamber

Metal “fire box” within the appliance that provides an area where burner flame mixes with combustion air thereby providing heat.

High Limit Switch

Safety device wired into the control system which is used to break an electrical circuit to the gas control valve in event of overheat situation.

Transformer

This device is responsible for reducing a higher incoming voltage (normally 120 V.A.C.) to a lower outgoing voltage. The lower voltage (24 V.A.C.) is essential to operate the ignition control module.

Ignition Control Module

Controls the ignition sequence and operation of the heater as well as monitoring the safety sevices. A major service feature is the board’s ability to diagnose component and flame failure by means of a diagnostic light located within the module. This light will provide a specific flash pattern repetitively, depending on the type of componenet failure that has occurred.
