Fuel Gas Installation Technician License

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

This license does not cover standalone piping work or service and repair of installed equipment — separate NH Mechanical Board licenses exist for those trades.

$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 per-month late penalty — once the license lapses, submit either the renewal application (expired less than 1 year) or restart initial licensure (expired 1 year or more) at the same $198 rate. 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 approved classroom education in fuel gas fitting theory, applicable codes, and safety, plus at least 1,000 hours of on-the-job experience in fuel gas installation, accumulated within 60 consecutive months. Holding an NH Fuel Gas Fitting Trainee registration is one qualifying path; applicants with out-of-state fuel gas fitting licensure may satisfy the requirement through equivalent documented experience (Mec 304.04(e)). After meeting education and experience requirements, pass the Installation Technician examination.

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 full initial licensure if your license has been expired more than 1 year — reapply, satisfy CE, and pass the examination. Per the OPLC education page (oplc.nh.gov/mechanical-safety-and-licensing-education-certification-requirements), OPLC offers an exam through approved providers as an alternative to the full 100-hour training course specifically for this reinstatement path. The fee is $198.

Operating Without This License Violates RSA 153

RSA 153 and Mec 305 require a valid Installation Technician license before performing any gas appliance installation work in New Hampshire. Penalties include fines, stop-work orders, and potential criminal charges.
