New Hampshire Fuel Gas Installation Technician License
The NH Mechanical Safety and Licensing Board (OPLC) issues the Fuel Gas Installation Technician license under RSA 153 — hold this license before connecting appliances to gas piping, installing venting, or performing startup tests on any gas appliance in New Hampshire.
This License Covers Four Specific Installation Scopes
Under Mec 305.03(a) and RSA 153:27, V, the Installation Technician license authorizes:
1. Installing natural gas and LP gas piping from the point of delivery (meter or first-stage regulator) to appliances
2. Installing gas appliances and utilization equipment
3. Installing venting and vent systems — including combustion air and dilution systems — for all gas appliances
4. Performing safety checks, equipment conversions, efficiency verification, and startup procedures
Servicing and repairing installed gas equipment requires the separate Fuel Gas Service Technician license (Mec 305.04).
$198 Fee — Apply, Renew, or Reinstate at the Same Rate
Plc 1002.25 (effective July 1, 2025) sets a single unified $198 fee for initial application, biennial renewal, and reinstatement for all fuel gas fitter license types. There is no separate late fee — an expired license does not authorize you to practice (RSA 310:8, III); within one year of expiration you reinstate through the renewal process at the same $198 rate (Mec 405.01), and after one year you must apply for initial licensure. Apply or renew at oplc.nh.gov/applications-mechanical-safety-and-licensing.
100 Classroom Hours and 1,000 OJT Hours Required
Mec 305.03(b) requires completion of at least 100 hours of education in gas theory, piping, appliance installation and venting, startup, and applicable codes, plus at least 1,000 hours of on-the-job experience in fuel gas installation, accumulated within 60 consecutive months.
6 CE Hours Required Every 2 Years
Mec 404.01(a) requires 6 hours of continuing education per 2-year renewal cycle — two separate board-approved 3-hour code update sessions. The same 3-hour course may not count twice. Complete CE before submitting renewal.
Expired Over 1 Year — Full Re-Licensure Required
Mec 405.01(b) requires you to apply for initial licensure if your license has been expired more than 1 year. The fee is $198.
Operating Without This License Violates RSA 153
RSA 153 no longer has its own licensing penalty section (RSA 153:37 was repealed in 2023). Unlicensed practice is unlawful practice under RSA 310:13 — after notice and a hearing the board may fine up to $10,000 for each offense, or the gain from the violation if greater, and may seek an injunction.

That window is the post-expiration late-renewal/reinstatement period, during which the credential is expired and may not be used until reinstated (RSA 310:8 III); it is not a penalty-free grace period, so it stays in prose only.
