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.
repopulation. Such inspection should consist of, but is not limited to, the following points of action: control panel to test for proper operation. -- Leak check of all pipe joints and hose connections. -- Insure proper clearance of heater to nearest combustible materials. -- Thorough cleaning of the exterior of the heater, its air inlets, combustion cones and filter (if applicable). -- Check for general cleanliness. Clean if necessary. -- Check for tightness of the gas hose connections.
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. 9.
GAS TRAIN ASSEMBLY Your heater is supplied with one of the following gas train assemblies. Refer to the appropriate illustrations.

ZONE CONTROL PANEL 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. Solenoid Zone Control System Fuel Medium Capacity Panel High Capacity Panel I34 L. P.
Start-Up Instructions WARNING 3. Fully depress the pilot button on the pilot safety control valve while applying flame to the main burner cone point. On initial start-up leave the main burner on for several minutes to bleed residual air from the system. 4. De-energize the solenoid of the zone control panel. The pilot flame should light and remain lit upon completion of transition from full output to pilot. Fire or Explosion Hazard ■ Do not force the gas control button.
Cleaning Instructions CAUTION ■ Disinfectants utilized in agricultural animal confinement buildings may contain chemicals damaging to components of the heater. ■ Protect the pilot gas control valve, pressure valve, and pilot relight 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. 5. Repeat Steps 3 and 4 until the cones and the venturi tube are no longer emitting dust. 6.
B. Use the clean-out feature at the start of each new growing cycle, or when plugging of the orifice occurs. Indications of pilot orifice plugging are: FIG. 10 WATER HOSE -- Weak pilot flame center -- Pilot outages FIG. 11 PLUNGER PUSH BUTTON BUTTON TOPOF OF BODY TOP BODY 4. Repeat steps 2 and 3 until water runs clean. 5. Remove the plastic bag and inspect the cones and venturi tube to make sure these areas are clean. 6.
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. 6. If any warning or instruction labels, dataplates, etc. become lost or hard to read, replace them immediately. Do not operate the heater until you have all instructions and can read and understand them. 2.
