2 Industrial Combustion 351 21st Street Monroe, WI 53566 608-325-3141 PREFACE It is the responsibility of the owner of this equipment to post and maintain a legible copy of this installation , Operation and Maintenance Manual while this equipment is in Service . Warning and caution references have been made in this Manual and should be adhered to for smooth operation of the burner. ! Warning This symbol precedes information which, if disregarded, may result in injury to the user of the burner or to others. ! Caution This symbol precedes information which, if disregarded, may result in damage to the burner.

3 NOTE: This symbol precedes information which is vital to the operation or maintenance of the burner. Model designations are based on the type of fuel(s) to be fired and the amount of furnace pressure to be overcome. Burner size is based on firing rate (rated input in Btu/hr). Model Standards Fuel-Air Atomization MTH Gas The equipment must be installed in accordance with applicable local, state, or Provincial installation Requirements including the National Electrical Code (NEC) and Associated Insurance Underwriters. Where applicable, the equipment shall be installed in accordance with the Provincial installation Requirements, or in their absence, the Canadian Gas Association (CGA) and and Canadian Standard Association (CSA) B140 and B139 (for oil burners) installation Codes shall prevail.

4 Authorities having jurisdiction should be consulted before installations are made. Oil and gas burning equipment shall be connected to flues having sufficient draft at all times to assure safe and proper operation of the burner. The MTH Series burners are designed to burn gas only as defined by ASTM D396-2010 specifications.

9 If the altitude > 2,000 ft then derate input by 4% for every 1,000 ft above 2,000 ft. For altitudes > 8,000 ft consult with factory. The amount of gas depends on 1,000 Btu / cubic foot (Btu / ) and specific gravity gas. When using the 50 Hz power supply, please consult the factory. MTH models have UL / cUL certification from 2,500 to 16,000 MBtu (other models are also available). MTH Series Standard Dimensions Accompanying dimensions are for layout purposes only.
