A qualified service agency must check for properoperating gas pressure upon installation of theheater.10. Light according to instructions on heater or withinowner's manual.11. The heater must have the proper gas regulator for theapplication. Use only the L.B. White regulatororiginally supplied with the heater. This regulatorincludes a POL fitting incorporating an excess flowvalve. The excess flow valve is a safety device whichprotects against discharge from the propane gassupply container if the regulator is broken off. If thePOL fitting is ever replaced, it needs to be replacedwith an L.B. White POL fitting. Failure to do so canresult in fires, explosions, loss of property, injury ordeath.12. A regulator must be connected to the gas supply sothat the pressure to the inlet of the gas control valveis regulated within the range specified on thedataplate at all times. Contact your gas supplier orthe L.B.white Co., if you have any questions.13. This heater is configured for use for propane gasvapor withdrawal only. Do not use the heater in anpropane gas liquid withdrawal system or application.If you are in doubt, contact the L.B. White Co., Inc.14. The heater must be installed so as not to interferewith or obstruct normal exits, emergency exits, doorsand walkways.15. Railing, fencing or suitable substitute materials mustbe used to keep the heating equipment from anypeople using and visiting the structure.16. The unit shall be located so that rain, ice, or snowdrainage from the structure does not af fectequipment operation. If the unit is mounted outside,it must be mounted above any pooled or standingwater. If the unit is to be located on the ground, asurrounding trench is recommended to drain any rain,ice or snow away from the unit.17. The ground and surrounding terrain must be clearedof any combustible vegetation and other combustiblematerials when the heater is mounted outside.18. Eventually, like all electrical/mechanical devices, thethermostat can fail. Thermostat failure may result inan underheating condition. The thermostat should betested to make sure it turns the heater on and offwithin a temperature differential of ±3°F (±1.5 °C).19. Take time to understand how to operate and maintainthe heater by using this Owner’s Manual. Make sureyou know how to shut off the gas supply to thebuilding and also to the individual heater. Contactyour fuel gas supplier if you have any questions.20. Any defects found in performing any of the service ormaintenance procedures must be eliminated anddefective parts replaced immediately. The heatermust be retested by properly qualified ser vicepersonnel before placing the heater back into use.The vaporization of propane is affected by several factors:the surface area of the container, the liquid level ofpropane, temperature surrounding the container, and therelative humidity. All of these factors are specific to a site.Therefore, a degree of experience and judgement isrequired to select the proper propane supply.Although experience is the best guide, the followingrecommendations can be used as a starting point. Thetable is based on experience in northern climates wherecold weather and high humidity are prevalent in the winter.If more or less favorable conditions prevail at a specific site,adjustments can be made on the basis of experience.8PROPANE GAS SUPPLY SIZING
