B. Electrical and Gas Requirements

It is your responsibility to have ALL electrical connections made by a properly licensed and competent electrician to assure that the electrical installation is adequate and conforms with local and state regula- tions or codes. In the absence of such codes, ALL electrical connections, material, and workmanship must conform to the applicable requirements of the National Electric Code ANSI/NFPA No. 70-LATEST EDITION.

The dryer installation must meet the AMERICAN NATIONAL STANDARD, National Fuel Gas Code ANSI Z223.1-LATEST EDITION, as well as, local codes and ordinances, and must be done by a qualified technician.

NOTE: Undersized gas piping will result in ignition problems and slow drying and can create a safety hazard.
