Safety Precautions WARNING Asphyxiation Hazard ■ Do not use this radiant heater for heating human living L.B. White Company to determine combustion air quarters. ventilation requirements of the heater. ■ Do not use in unventilated areas. ■ The flow of combustion and ventilation air must not be obstructed. ■ Lack of proper ventilation air will lead to improper combustion. ■ Proper ventilation air must be provided to support the combustion air requirements of the heater being used.
Safety Precautions 1. Do not attempt to install, repair or service this heater or the gas supply line unless you have continuing expert training and knowledge of gas heaters. Qualifications for service and installation of this equipment are as follows: QUALIFICATIONS FOR SERVICING AND INSTALLATION: a.
14. A qualified service person shall inspect the heater and its gas train at least on an annual basis. This should consist of, but is not limited to, the following points of action: -- Thorough inspection of the heater’s component parts for corrosion, stripped threads, etc. with subsequent parts replacement as necessary. -- Gas pressure checks. -- Start-up and shut down of the heaters and zone control panel to test for proper operation. 15. Turn off the gas supply when the heater is not in use.
involved for cleanliness in the thread areas and proper application of pipe compound before further tightening. 12. The heater is designed for either L.P. vapor withdrawal or natural gas, depending on model number. Do not use this heater in an LPG liquid withdrawal system. Do not permit LPG in liquid form to enter the heater at any time. -- Tighten the gas connection as necessary to stop the leak. 13.
GAS TRAIN ASSEMBLY Your heater is supplied with one of the following gas train assemblies. Refer to the appropriate illustrations.

ZONE CONTROL PANEL COMPONENT FUNCTION AND INSTALLATION The zone control panel is a remote mounted control system allowing the operation of a specific amount of heaters within a certain zone of the building. These panels will control the following quantity of heaters depending on fuel type. Modulating System Model and Heat Output Fuel I17 L. P.
Start-Up Instructions 3. Fully depress the button on the safety control valve while applying flame to the inner cone point. Remove the vinyl cap from the safety valve if necessary. See Fig.8. Keep the button fully depressed for about 30 seconds until the inner cone stays lit. Release the button. Allow outer combustion cone to heat up completely. Replace the cap onto the safety control valve. WARNING Fire or Explosion Hazard ■ Do not force the safety control valve button.
Cleaning Instructions CAUTION ■ Disinfectants utilized in agricultural animal 6. Return the heater to its normal hanging position and relight the heater. FIG. 9 confinement buildings may contain chemicals damaging to components of the heater. ■ Protect the safety gas control valve and pressure valve by wrapping these components with a plastic bag before disinfecting. ■ Always make sure to remove the plastic bag or other protective covering before start up.
FIG. 11 B. FILTER (accessory) A. During continued use: WATER HOSE - Remove filter and shake off dust. - Do not squeeze or tap filter while filter is installed on heater. Doing so will cause dust to be blown into venturi tube or combustion cones. B. After continued use or before building repopulation: 3. Repeat steps 2 and 3 until water runs clean. - Remove filter and shake off dust. - Use compressed air or water (standard faucet pressure) to clean it.
Maintenance Instructions 1. Have your gas supplier check all gas piping annually for leaks or restrictions in gas lines. Also, at this time have your gas supplier clean out the sediment trap on the zone control panel of any debris that may have accumulated. 2. The heater’s surrounding area shall be kept clear and free from combustible materials, gasoline, and other flammable vapors and liquids. 3. Regulators can wear out and function improperly.
SAFETY GAS CONTROL VALVE 1. Disconnect the gas hose. 2. Disconnect the thermocouple from the safety valve. FIG. 12 SAFETY CONTROL VALVE 3. Loosen the jam nut on the air housing. JAM NUT O-RING 4. Turning counterclockwise, remove the safety control. AIR HOUSING When reassembling: -- Ensure o-ring is seated in jam nut. -- Apply Loctite (supplied with replacement) to first four threads of air housing.
THERMOSTATIC HEAD and MODULATING VALVE Individual Control Heaters and Modulating Zone Panels ■ The following service instructions apply to individual control or zone control heaters. ■ The head assembly includes the adjustable thermostatic head, capillary and sensor. The part numbers for the thermostatic heads are: -- Zone panel head: Part No. - 09416 w/ 26 ft. capillary -- Individual control head: Part No. - 09415 w/ 6 ½ ft.
BURNER COMBUSTION CONES and GASKET Very little servicing is required for the combustion cones and gasket. Routine cleaning is sufficient to ensure that the cones remain unblocked by dust and dirt. Periodic tightening of the the three burner plate nuts, (see Fig.18) ensures that the heater operates to normal combustion characterisitics. 4. Inspect the inner cone. See Fig.21. If the cone is in good condition, (cone weld seam not split or tip is not missing) then clean using the compressed air method.
THERMOCOUPLE 1. Loosen the thermocouple connector nut at the safety control valve. See Fig. 23. FIG. 24 2. Loosen the screw securing the clip holding the thermocouple’s auto reset temperature switch to the air housing. See Fig. 23. UPPER RETAINING NUT 3. Loosen upper retaining nut on thermocouple. See Fig. 24. KEY HOLE SLOT 4. Remove the thermocouple, with nuts and cover, from the heater. THERMOCOUPLE INSTALLED 5.
GAS PRESSURE CHECKS A. Preparation C.Reading Pressures 1. Obtain a pressure gauge test kit part no. 20736. 1. With the heater operating at full heat output and at minimum heat, the pressure gauge should read the pressure specified on the dataplate of the zone panel. 2. Close the fuel supply valve to the heater. 3. Brush or blow off any dust and dirt on or in the vicinity of the gas control valve. 4. Disconnect the gas hose from the heater. 2.
