NH Gas appliance venting rule changes yet again

Granite State Trade School has learned that, according to the State Fire Marshal’s Office, based on a failure of the state legislature to ratify and formally adopt the January 1st, 2016 amendment that changed the way category III and Category IV gas appliances were vented, the amendment has now “sunsetted” and is no longer a provision of the code.


What does this mean?  Good news in some ways.  The way the venting amendment was written placed the full responsibility to select the proper venting material squarely on the shoulders of the installer, essentially exempting the manufacturer if they recommended some material other than what the amendment allowed.  Now we are back to just abiding by the 2009 NFPA 54 which says to install according to manufacturer’s recommendations when it comes to plastic pipe.  The entry is found in chapter 12, specifically 12.5.3 under Plastic Vent Joints.

Potential bad news could be included in the reversion back to the code as the code also says in 12.5.2 that the venting material must be “approved”.  With all the recent developments concerning PVC being used as a gas vent material, who will approve PVC as a vent material and who will not approve it?  The state inspectors have indicated that they won’t approve PVC as a venting material, even though the manufacturers continue to tell installers to use it in their installation instructions.

So where do we go from here?  We are still on the 2009 NFPA 54 code, and now their is no NH amendment to contend with.  We install according manufacturer’s instructions, checking with the local authority having jurisdiction to see if they have any issue or local ordinance that prohibits the use of whatever venting material the manufacturer recommends.

Granite State Trade School will wait to see what the next move is for NH in terms of this Category III and Category IV venting discussion.  Massachusetts has recently passed what looks to be a complete ban on PVC as a gas venting material.  Will NH follow suit?



Is the gas appliance venting law about to change again?

The venting law in NH is already the topic of much discussion since it was adopted last January.

At Granite State Trade School we have been teaching the specifics of this law to our licensing students and our gas continuing education students.

Is the law about to change again?  Based on the Massachusetts Board of Examiner’s meeting on Oct 4th, 2017 that indicated that state will likely ban PVC altogether for venting gas appliances, it seems likely NH will review it’s policy as well.

Stay posted to this blog site on our website granitestatetradeschool.com for any developments.

What is required to obtain a New Hampshire fuel gas fitter license

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.

Still misunderstanding the NH venting amendment of Jan 2016

It has been over a year since the state of NH made the venting amendment changes to NFPA 54.

Yet rumors and myth still prevail, heightened by local inspector interpretations and requirements which further cloud the issue.

Granite State Trade School always seeks to help in matters of interpreting code and changes to the fuel gas equipment installation and venting.

The information contained in this blog can be found in Informational Bulletin 2016-01 from the NH Dept of Safety, State Fire Marshal’s Office.

Myth:  PVC has been banned in the state of NH for venting appliances.

Truth:  PVC is not banned and can still be used IF the manufacturer’s installation instructions allow for it AND the temperature potentially passing through that venting material is limited so as not to cause damage.

Myth:  All PVC in existence mus be changed out by a licensed service tech who comes in contact with or service the appliance.

Truth:  The venting amendment is not retroactive and there is no requirement to remove existing venting materials if they show no sign of damage or endangerment to the occupants.

Myth:  A mixture of venting materials can be used on a single appliance, such as PVC and CPVC.

Truth:  The venting materials must be installed as a complete system.

More information is available in the information bulletin, but these are some highlights that are most commonly misinterpreted.

When will NH adopt the 2015 NFPA 54 code book?

Granite State Trade School attempts to keep our finger on the pulse of legislative bodies that make decisions concerning the plumbing and Fuel Gas codes here in NH.

The Mechanical licensing board has submitted their approval to the adopt the 2015 NFPA 54 code book to the legislature.  We expect the NH mechanical licensing board to adopt the 2015 version by July of 2017.

New Hampshire Gas License renewal requirements

New Hampshire Fuel gas licenses are normally issued for two years and expire on the last day of the birth month of the license holder.

The present educational requirement for renewal of that license as set by the NH Mechanical Licensing Board of the State Fire Marshal’s Office requires that each license holder complete 6 hours of Code related training from an approved seminar provider over the two year license period prior to renewal.

That education can come in each of the two licensing years, or in some cases all in the same year.  The 6 hour mandate does not specifically state 3 hours in each of the licensing years, just three hours per year.

Where does a license holder go to get the training they need?  A list of the approved seminar providers is on the NH Mechanical Board website.

Granite State Trade School offers one of the most convenient and comprehensive continuing education schedules, all by approved providers, right in Raymond NH. Some of these classes offer 3 hours of credit, while some offer all 6 hours in the same day.  Granite State Trade School also conducts approved gas license renewal seminars at various locations throughout the state, to include FW Webb locations in Dover, Madison, Gilford, Lebanon, as well as Plumber’s Supply in Lebanon.

Lp and Natural Gas- Sediment Trap vs. Drip Leg


Granite State Trade School offers Continuing education for Fuel Gas Fitters.

Much of the training centers around NH Gas Code and what is contained in the 2009 NFPA 54 code book.

One of the topics that often gets confused deals with sediment traps and drip legs.

Chapter 7.6 of NFPA 54, 2009 addresses drip legs.  It begins with the phrase :For other than dry gas conditions, a drip shall be provided…”  So the first thing to take into account is that the standard Natural Gas and LP gas used in our region are considered dry gas.  Therefore, no drip leg would be required.

However, the code in 7.6.3 distinguishes that Sediment Traps are something different, and the code directs the reader to 9.6.7 to get the required info pertaining to the installation of sediment traps.

9.6.7 paraphrased says sediments traps ARE required for natural gas and lp systems prior to each appliance inlet, with exceptions listed as illuminating appliances, clothes dryers, ranges, decorative hearth products such as fireplaces and gas logs, and outdoor gas grills.  It DOES NOT exempt all outside appliances. The exact method of installing the sediment is also covered, depicting where the shut off is located, how long the trap portion must be, etc.

So simply stated, sediment traps are most likely REQUIRED each natural gas or LP appliance, and Drip Legs are most likely NOT required on the system, unless some special gas mixture beyond the standard LP and Natural gas is being introduced.


Plumber’s continuing education now on Friday’s as well as Saturdays in 2017

Granite State has been a leader in providing flexible continuing education for fuel gas license holders and for plumbers.
