A LICENSED APPRENTICE GASFITTER WHO HAS NOT SUCCESSFULLY OBTAINED A JOURNEYMAN GASFITTER LICENSE THROUGH THE EXAMINATION PROCESS FOLLOWING SIX EXAMINATION ATTEMPTS SHALL NOT BE RENEWED. AN APPRENTICE WHOSE LICENSE HAS NOT BEEN RENEWED FOR NON-COMPLIANCE WITH THE REQUIREMENTS OF THIS SECTION SHALL BE PERMITTED TO PETITION THE BOARD FOR REINSTATEMENT, FOR GOOD CAUSE, HIS OR HER APPRENTICE LICENSE. PG 2 Slide 5: Enforcement of C.E. Requirements Any licensee who does not complete the required clock hours of continuing education within the license renewal cycle shall be responsible for completing make-up classes covering the Board approved material for the continuing education missed. In addition to any makeup classes, all licensees who fail to complete continuing education requirements for any renewal cycle shall be subject to Board review and disciplinary action that may include, but not be limited to the issuance of fines, denial of applications for additional licenses. The board is under no obligation to warn a Licensee of non-compliance with continuing education requirements prior to commencing disciplinary action, however, said action shall be subject to any hearings required by law. PG 3 Slide 6: Enforcement of C.E. Requirements Cont. (5) Reinstatement of lapsed/expired/suspended licenses. (a) Licensees who have failed to renew their licenses must fill out any applications required by the Board and must pay any back or late fees prior to board consideration. (b) Licensees who are lapsed/expired must meet the following additional requirements for reinstating their licenses: 1. If expired for four years or less, Licensees must complete the continuing education hours for the current renewal cycle prior to applying to reinstate their license. 2. If expired for more then four years, licensees must complete the continuing education hours for the current renewal cycle and pass the full Board examination for their license prior to being reinstated. However, Licensees shall not be required to take the examination if they completed all Board required continuing education requirements for each two year cycle during the period in which their license was expired. PG 4 Slide 7: Enforcement of C.E. Requirements Cont. 3. Without special Board approval, no waivers of continuing education granted under any other section of these regulations shall apply for purposes of reinstating a lapsed or expired license. (c) Unless a decision or consent agreement explicitly states otherwise, licensees who are suspended must complete all continuing education in order to qualify for reinstating their licenses. (d) This section shall not be deemed to sanction unlicensed practice. An individual practicing with an expired or suspended license may face disciplinary action up to and including revocation of the right to renew that license. PG 5 Slide 8: Qualifications for admission to the Master Gasfitter Examination An applicant who is a licensed journeyman gas fitter shall be required to complete the following education and experience criteria to be eligible for admission to the master gasfitters examination: Experience.

Education. The applicant shall furnish documentation satisfactory to the Board of having completed 50 clock hours of gasfitting theory in a master Gasfitter educational program, culminating in a school or instructor designed examination to ensure competency. This program must meet the Board administered requirements of 248 CMR 11.00. However, applicants who have completed the 110 hour three tier Gas Fitter Educational Program as approved by the Board and described in 248 CMR 11.06 shall be exempt from having to obtain additional education. PG 7 Slide 10: EMPLOYER CERTIFICATION OF APPLICANT HOURS IN GENERAL, EMPLOYERS MUST BE ABLE TO PROVIDE SOCIAL SECURITY RECORDS FOR THEIR EMPLOYEES WHEN THOSE EMPLOYEES SEEK A LICENSE. HOWEVER, THE BOARD HAS NOTED THAT CERTAIN INDIVIDUALS ARE UNABLE TO PRODUCE THOSE RECORDS AND HAS CHECKED “NO” ON THE RELEVANT FORM. THESE RECORDS ARE NECESSARY FOR THE BOARD AS THEY SHOW A SUPERVISORY EMPLOYMENT RELATIONSHIP GENERALLY NECES- SARY FOR AN APPRENTICESHIP. WHEN SUCH A SITUATION TAKES PLACE, THE FORM SHALL BE DEEMED TO BE INCOMPLETE AND THE FOLLOWING POLICY APPLIES: A CERTIFICATION BY THE SUPERVISING MASTER PLUMBER/GAS- FITTER, UNDER PAINS AND PENALTIES OF PERJURY, THAT THE APPLICANT WAS NOT PAID FOR THE TIME THAT THEY WORKED. A COPY OF THE CONTRACT BETWEEN THE MASTER AND THE APPLICANT SHOWING AN AGREEMENT THAT THE WORK WAS UNPAID. PG 8 Slide 11: A LIST OF JOBS, WITH CONTACT INFORMATION, TO ALLOW THE BOARD TO VERIFY INDEPENDENTLY THAT THE APPLICANT WORKED ON THOSE JOBS. IF THE RECORDS ARE UNAVAILABLE BECAUSE THE APPLICANT WAS ISSUED AN IRS 1099 FORM, THUS INDICATING SOCIAL SECURITY WAS NOT WITHHELD, THE FOLLOWING MUST OCCUR: THE EMPLOYING MASTER SHOULD BE NOTIFIED THAT THEY MAY CONTACT THE RELEVANT TAX AUTHORITIES IF THE USE OF THE 1099 WAS IN ERROR. IN THE EVENT THE MASTER DOES NOT CORRECT THE 1099 ISSUE AND BECOME ABLE TO PROVIDE SOCIAL SECURITY RECORDS, THEY MUST FILL IN AN AFFIDAVIT APPROVED BY THE BOARD REGARD- ING THE APPLICANT’S EMPLOYMENT. IN THIS INSTANCE THE EMPLOYER MAY ALSO BE REQUIRED TO APPEAR BEFORE THE BOARD. EMPLOYER CERTIFICATION OF APPLICANT HOURS CON. PG 9 Slide 12: IT IS THE OBLIGATION OF ALL MASTERS TO ADHERE TO THIS POLICY WHEN THEY AGREE TO TAKE ON AN APPRENTICE. FAILURE TO ADHERE TO THESE PROVISIONS CONSTITUTES UNPROFESSIONAL CONDUCT AND MAY SUBJECT THE MASTER TO DISCIPLINARY ACTION. AS THE APPLICATION IS CONSIDERED INCOMPLETE WITHOUT ADHERENCE TO THIS POLICY, AN APPLI- CANT MAY BE SUBJECT TO HAVING THEIR APPLICATION BEING RETURNED AS INCOMPLETE. SUCH AN APPLICANT MAY CHOOSE TO FILE A COMPLAINT AGAINST THE MASTER. IF SUCH A COM- PLAINT HAS BEEN FILED, THE BOARD WOULD HAVE JUSTIFICA- TION FOR GRANTING THE APPLICANT AN APPEARANCE BEFORE THE BOARD. THE BOARD MAY THEN BE WILLING TO CONSIDER ADDITIONAL EVIDENCE BY THE APPLICANT DEMONSTRATING THAT ALL LAWS AND REGULATIONS HAVE BEEN ADHERED TO AND THAT THE APPLICANT HAS ACCRUED THE REQUIRED EXPERIENCE FOR THE LICENSE SOUGHT. EMPLOYER CERTIFICATIONS OF APPLICANT HOURS CON. PG 10 Slide 13: PG 11 Slide 14: Changes in the Plumbing and Gas Permit Applications PG 12 NEW PERMIT OLD PERMIT Slide 15: Emergency Installations 248 CMR 4.03 Rule 3 In case of emergency a gas appliance may be turned on temporarily by the licensed installer provided: (a) The installer has tested the piping in accordance with the appropriate section of 248 CMR. (b) The installer and the supplier are satisfied that the installation of piping and use of the equipment will assure safe operation. (c) The inspector (or the chief inspector if more than one inspector) is notified and a regular inspection is made at the earlier opportunity but no later than the next working day. PG 13 Slide 16: Notification 248 CMR 3.05 It shall be the duty of the permit holder or the licensed plumber or gas fitter employed by the master plumber or gas fitter to give notice to the inspector when plumbing or gas fitting work is ready for inspection. The licensed plumber or gas fitter or the permit holder shall establish that the work will stand the prescribed test and that the roughing-in has been completed as far as practicable before giving the notification. If the inspector determines that the work will not pass the test and/or requirements of 248 CMR 3.00 through 10.00 necessary corrections shall be made and the work shall be resubmitted for inspection. PG 14 Slide 17: Covering of work 248 CMR 3.05 New plumbing and gas fitting work and such portions of existing systems that may be directly affected by new work shall not be covered until it has been tested if required by the inspector and the inspector has certified that the work is in compliance with M.G.L.C. 142 and 248 CMR 3.00 through 10.00. If new plumbing and gas fitting work and such portions of existing systems that may be directly affected by new work are covered before being tested and approved by the inspector, the work shall be uncovered for inspection after the inspector has issued a notice to uncover to the permit holder responsible. PG 15 Slide 18: CSST Update Regarding Counterstrike In 248 CMR Section 5.02 (4) other standards: It states, in applying NFPA-54, Reference should also be made to the manufacturer’s instructions. In all CSST installations, bonding requirements shall comply with the manufacturer’s installation instructions, for this reason, it is the Manufacturer’s responsibility to insure that the licensed installer’s have the current edition of the installation Instructions. This will help to eliminate confusion when and if the instructions are requested by the inspector. Based upon the amended verbiage listed in the latest edition of the Tracpipe installation instructions dated June 2009, in section 4.10A (3) the manufacturer states: unlike Tracpipe, there are no additional bonding requirements for Counterstrike imposed by the manufacturer’s installation instructions. Counterstrike is to be bonded in accordance with the National Electrical Code NFPA 70 Article 250.104 in the same manner as the minimum requirements for rigid metal piping. However, installers must always adhere to any local requirements that may conflict with these instructions. PG 16 Slide 19: Section 4.10 – Electrical Bonding/Grounding WARNING! FIRE/FUEL GAS PIPING The TracPipe flexible gas piping MUST be bonded to an effective ground-fault. Current path per NFPA 54 in accordance with the instructions contained in this section. It is HIGHLY RECOMMENDED to bond all mechanical systems to the building’s grounding electrode. Definitions: Grounding: The process of making an electrical connection to the general mass of the earth. This is most often accomplished with ground rods, ground mats or some other grounding system. Low resistance grounding is critical to the operation of lightning protection techniques. Bonding: The process of making an electrical connection between the grounding electrode and any equipment, appliance, or metal conductor pipes, plumbing, flues, etc. Equipment bonding serves to protect people and equipment in the event of an electrical fault. PG 17 Slide 20: Section 4.10 – Electrical Bonding/Grounding Cont. Equipotential Bonding: The process of making an electrical connection between the grounding electrode and any metal conductor: pipes, plumbing, flues, etc., which may be exposed to a lightning strike and can be a conductive path for lightning energy towards or away from the grounding electrode. 2. The TracPipe gas piping system shall be bonded in accordance with these instructions and the National Fuel Gas Code, NFPA 54/ANSI Z223. In the event of a conflict between these instructions and local codes, the local codes shall control. The piping system is not to be used as a grounding conductor or electrode for an electrical system. PG 18 Slide 21: Section 4.10B – Bonding Conventional Yellow Jacketed Tracpipe For bonding of the conventional yellow-jacketed Tracpipe system, a bonding clamp must be attached to the brass AutoFlare fitting adapter (adjacent to the pipe thread area – See Figure 4-21) or to a black pipe component (pipe or fitting) located in the same electrically continuous gas piping system as the AutoFlare fitting. The corrugated stainless steel portion of the gas piping system SHALL NOT be used as the bonding attachment point under any circumstances. The bonding conductor shall be bonded per the National Electrical Code NFPA 70. Bonding electrode conductor sizing shall be in accordance with NFPA 70 Article 250, Section and Table 250.66 Note: TracPipe Bonding clamps have been tested and approved by CSA in Accordance with UL 467/CSA C22.2 No. 41-07 when installed on Black Iron/Galvanized steel pipe and TracPipe AutoFlare brass hex fittings (report #3000657, 5/2/08) PG 19 Slide 22: Section 4.10A Counterstrike Installation Instructions Counterstrike CSST with the black, protective sleeve uses the same easy to install AutoFlare fittings as conventional TracPipe with the yellow jacket. Counterstrike systems are sized in the same manner as TracPipe either using capacity tables or other approved methods. The instructions for cutting the tubing and for making fitting connections to CounterStrike are identical to standard yellow jacketed TracPipe. The jacket shall remain intact as much as practical when attaching the fitting. Unlike TracPipe, there are no additional bonding requirements for CounterStrike imposed by the manufacturer’s installation instructions. CounterStrike is to be bonded in accordance with the National Electrical Code NFPA 70 Article 250.104 in the same manner as the minimum requirements for rigid metal piping. However, installers must always adhere to any local requirements that may conflict with these instructions. Counterstrike meets building code requirements (ASTM E84) with respect to flame spread and smoke density. This permits installation in drop ceilings used as return air plenums. CounterStrike has thru penetration UL classifications for 1, 2, and 4 hours with the black jacket intact. PG 20 Slide 23: Section 4.10B – Bonding Conventional Yellow Jacketed Tracpipe Cont. IMPORTANT SAFETY PRECAUTION -Failure to properly bond the conventional yellow-jacketed TracPipe flexible gas piping may lead to damage to the CSST system in the event of a lightning strike. -The lightning may arc to or from another metal system, creating a hole in the wall of the TracPipe CSST. -This presents a risk of fire in the building, and could lead to serious personal injury or significant property damage. 2. Lightning is a powerful and unpredictable natural force, and it has the capacity of damaging gas piping systems due to arcing between the gas piping system and other metallic systems in the building. 3. If the building to be piped is in a high lightning flash density area or a region with a high number of thunderstorm days per year, (figure 4-22) consideration should be given to utilizing the Lightning Risk Assessment method given in Annex L of NFPA 780 for a determination of the need for a lightning protection system. PG 21 Slide 24: Section 4.10B – Bonding Conventional Yellow Jacketed Tracpipe Cont. Notes: If possible, avoid running the bonding jumper a long distance through the building. The connection should be as short as possible. Gas meter should be near the electrical service if possible. If not, the bond can be connected at any point near the electrical service per figure 4-21. Lightning induced voltages seeking ground are subject to impedance; consider utilizing a braided or stranded bonding jumper for greater surface area, rather than solid wire. PG 22 Slide 25: Requirements are the Same for standing pilots or electronic ignition A valve shall be located on the main gas line feeding the appliances served by the draft hood, and shall stop the flow of gas to the appliances upon loss of draft. No by-pass of gas solenoid valve is allowed Valves shall be controlled by a draft providing switch measuring draft within the hood allowing valve to open only when the fan is operational or damper 100% open Valves must be manually reset when lock out condition is correct, due to hood draft not proven. Reset shall not be automatic. Commercial cooking hoods Draft hood interlock requirements NFPA 54 10.3.5.2 2002 edition Next page PG 23 Slide 26: Questions from previous page What if I am only changing one appliance under the hood? Install valve on the one appliance Can I use an alternate device in lieu of the air switch to determine draft failure such as A C.O. detector? Yes If the following functions are included When device fails (or sunsets) it will leave the gas valve closed until replaced No by–pass allowed #4 An audible alarm shall sound when the C.O. level is reached #3 Detector shall be interlocked with gas valve. Gas valve shall be equipped with a manual reset integral or otherwise #2 C.O. detection must be taken from a minimum of two separate locations. 2. May be one location if manufacturer’s instructions allow. PG 24 Slide 27: Air for Combustion and Ventilation 8.3.1 Air for combustion, ventilation, and dilution of flue gases for utilization equipment installed in buildings shall be obtained by application of one of the methods covered in 8.3.2 through 8.3.6. Where the requirements of 8.3.2 are not met, outdoor air shall be introduced in accordance with methods covered in 8.3.3 through 8.3.6. Exception No 1 – This provision shall not apply to direct vent appliances. Exception No 2 – Type I clothes dryers that are provided with makeup air in accordance with 9.43. Indoor Combustion Air 8.3.2 The required volume of indoor air shall be determined in accordance with the method in 22.214.171.124 or 126.96.36.199 except that where the air infiltration rate is known to be less than 0.40 ACH the method in 188.8.131.52 shall be used. The total required volume shall be the sum of the required volume calculated for all appliances located within the space. Rooms communicating directly with the space in which the appliances are installed through openings not furnished with doors, and through combustion air openings sized and located in accordance with 184.108.40.206 are considered a part of the required volume. PG 25 Slide 28: INDOOR COMBUSTION AIR 220.127.116.11 THE TOTAL REQUIRED VOLUME SHALL BE THE SUM OF THE REQUIRED VOLUME CALCULATED FOR ALL APPLIANCES LOCATED WITHIN THE SPACE. ROOMS COMMUNICATING DIRECTLY WITH THE SPACE IN WHICH THE APPLIANCES ARE INSTALLED THROUGH OPENINGS NOT FURNISHED WITH DOORS, AND THROUGH COMBUSTION AIR OPENINGS SIZES AND LOCATED IN ACCORDANCE WITH 18.104.22.168 ARE CONSIDERED A PART OF THE REQUIRED VOLUME. OUTDOOR COMBUSTION AIR 8.3.3 OUTDOOR COMBUSTION AIR SHALL BE PROVIDED THROUGH OPENING(S) TO THE OUTDOORS IN ACCORDANCE WITH THE METHODS IN 22.214.171.124 OR 126.96.36.199. THE MINIMUM DIMENSION OF AIR OPENINGS SHALL NOT BE LESS THAN 3 IN. TWO PERMANENT OPENINGS METHOD 188.8.131.52 TWO PERMANENT OPENINGS, ONE COMMENCING WITHIN 12 IN. OF THE TOP AND ONE COMMENCING WITHIN 12 IN OF THE BOTTOM OF THE ENCLOSURE. SHALL BE PROVIDED. THE OPENINGS SHALL COMMUNICATE DIRECTLY, OR BY DUCTS, WITH THE OUTDOORS OR SPACES THAT FREELY COMMUNICATE WITH THE OUTDOORS. PG 26 Slide 29: TWO PERMANENT OPENINGS 184.108.40.206(2) PG 27 DUCTS MUST BE THE SAME AREA AS THE OPENINGS TO WHICH THEY CONNECT.
