New Hampshire currently recognizes 5 different fuel gas fitter licenses:
Service Technician, Equipment/Venting installer, Gas Piping, Hearth Installer, Domestic Appliance technician
The state law requires all those entering into the fuel gas fitting trade to start with a Trainee License. This is obtained through the state Fire Marshal’s office, with little requirement on the applicant. Once this license is obtained, the trainee can now begin to accrue required field hours toward an actual gas license while working under the direct supervision of a licensed fuel gas fitter.
With 1,000 hours of field experience and a 60 hour gas piping course from Granite State Trade School, the Trainee would be eligible to upgrade to a gas piping license.
With 1,000 more hours of field experience and a minimum of a 40 hour equipment installer course from Granite State Trade School, the gas piping license holder can upgrade to the Equipment/Venting Installer license.
After obtaining the Equipment Installer license, with a minimum of a 40 hour service technician course, the license holder can obtain the gas Service Technician license.
Hearth Installer is a “stand alone” license that offers no crossover path to the three licenses listed above. Individuals must obtain 1,000 hours of field experience as a trainee, pass a 60 hour long course related to the gas hearth industry.
The Domestic Appliance technician is the newest license and like the Hearth Installer it is a Stand alone license. Individuals must obtain the 1,000 hours of field experience as a trainee and complete a minimum of a 40 hour course offered by Granite State Trade School, as well as be factory trained on the equipment they intend to install. They are limited to work downstream of the appliance shutoff and only on domestic appliances listed here: Generators, pool heaters, outdoor BBQ’s/outdoor living equipment, household cooking equipment, clothes driers.
