Before installing or operating this heater, make sure you have read and understand this manual. |\n| --- |\n| IMPROPER INSTALLATION OR LACK OF MAINTENANCE WILL VOID THE WARRANTY.\u003Cbr>The most critical sections of this manual are\u003Cbr>• Correct Draft Over Fire-Page 21\u003Cbr>• General Maintenance Requirements-Page 24\u003Cbr>Identical to any gas or oil burner, without adequate draft over the fire, the combustion gases cannot escape resulting in an overheated combustion chamber. Even if the burner is installed correctly and adequate draft achieved, a flue passage blockage will affect the draft. Burning used oil is similar to burning wood. A fine gray ash accumulates in the chamber and flue passages. This accumulation of ash will eventually affect the draft. It is important to remove this ash before the draft is affected.\u003Cbr>These topics are discussed in detail on the pages listed above. Please familiarize yourself with these sections of your manual. Spending a few minutes to review this material will assure that you receive the return on investment that you expect from your heater. |\n\nForm I-RA/RAD 150/250, Page 2  \nTable of Contents  \nInstallation....................4-18  \nIntroduction.................................... 4  \nUse.................................................. 4  \nCodes and Regulations ................ 4  \nWarranty......................................... 4  \nSafety Warnings ............................ 5  \nSecondary Heat Source................ 5  \nFuels............................................... 5  \nHazardous Atmosphere................ 5  \nVenting ........................................... 5  \nAir for Combustion ....................... 6  \nNon-Compliance............................ 6  \nUnpacking and Inspection............ 6  \nParts Carton................................... 7  \nHeater Placement .......................... 8  \nMinimum Clearances from Combustibles ................................ 8  \nHigh Altitude Installation .............. 9  \nFuel Tank, Pump, and Supply Lines ........................... 10  \nFuel Tank...................................... 10  \nGeneral Requirements................ 10  \nPump ............................................ 11  \nSupply Lines Installation............ 11  \nTypical Installation ...................... 12  \nMounting the Heater.................... 13  \nWeights ........................................ 13  \nSuspension.................................. 13  \nVenting the Heater ...................... 14  \nGuidelines for the Vent System . 14  \nDetailed Vent System Information ............................ 15  \nDraft Regulator ............................ 16  \nInstalling Ducts............................ 17  \nInlet Air Duct ................................ 17  \nDischarge Duct............................ 17  \nPower Installation........................ 18  \nHeater Power ............................... 18  \nPump Power Installation ............ 18  \nHeating Thermostat .................... 18  \nHeater Start-Up .......... 19-23  \nSystem Check .............................. 19  \nPriming and Leak Check ............ 19  \nHeater Start-Up ............................ 21  \nStart-Up Procedure ..................... 21  \nCheck Test-After Start-up ......... 21  \nMaintenance...............24-33  \nGeneral Maintenance Requirements .......................... 24  \nMaintenance Schedule ............... 24  \nMaintenance Procedures ............ 25  \nService ....................... 3","cbCaiv6wfOWqO91w","https://ap.wps.com/l/cbCaiv6wfOWqO91w","pdf",1211890,52,"English","# Table of Contents\n## Installation\n## Maintenance\n## Service\n## Appendix\n## Index","[{\"question\":\"Why is correct installation and maintenance critical for warranty coverage?\",\"answer\":\"The manual states that improper installation or lack of maintenance will void the warranty.
