Session III

1099 Board Policy Explanation




Policy regarding Employer Certification of Applicant Hours

Adopted June 24, 2009

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 necessary for an apprenticeship. When such a situation takes place, the form shall be deemed to be incomplete and the following policy applies: 1. If the records are unavailable because the applicant was unpaid, then the following must

be provided:

A. 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.

B. A copy of the contract between the master and the applicant showing an

agreement that the work was unpaid.

C. A list of jobs, with contact information, to allow the Board to verify independently that the applicant worked on those jobs.

2. 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:

A. The employing master should be notified that they may contact the relevant tax authorities if the use of the 1099 was in error.

B. 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 regarding the applicant’s employment. In this instance the employer may also be required to appear before the Board.

3. 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 applicant 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 complaint has been filed, the Board would have justification 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.

Requirements for Emergency Installations and Inspections


248 CMR 4.03 Rule 3. In cases 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; and c. the Inspector (or the chief inspector if more than one inspector) is notified and a regular Inspection is made at the earliest opportunity but not later than the next working day. 248 CMR 3.05 Permits and Inspections 6. In cases of emergency, a plumbing fixture may be turned on temporarily by the licensee provided: a. the installer has tested the piping in accordance with the appropriate requirements of 248 CMR; b. the installer and local water/sewer superintendent (if applicable) are satisfied that the installation of piping and use of equipment will assure safe operation; and c. the Inspector (or the chief inspector if more than one inspector) is notified and a regular inspection is made at the earliest opportunity and in no case later than the next working day. 248 CMR 3.05 (3)(d) Notification. 1. 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. 2.

Session III

CSST UPDATE




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 manufactures installation instructions, for this reason, it is the manufacturers 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.




CSST Update — March 2009 Informational use only. For official Board interpretation, contact the Board of Examiners

of Plumbers and Gas Fitters at (617) 727-9950 or:

www.ma. gov/dplfboards/pl

All CSST piping systems shall be bonded according to manufacturer’s instructions,

including Trac Pipe’s Counterstrike. The bonding shall be done by a licensed electrician or homeowner (if the municipality

allows).

INSTALLER

Cheek with the local electrical inspector to be sure he will issue permit and inspect the bonding. If he will not issue a permit, DO NOT INSTALL CSST.

Install the CSST piping system.

INSPECTOR

Before inspecting, determine if an electrical permit for the bonding has been issued by the electrical inspector.

If the permit has been issued, you can inspect the CSST piping system according to the

Fuel Gas Code. DO NOT INSPECT THE BONDING, since this will be done by the electrical inspector.

NOTES If replacing an appliance and no ADDITIONAL CSST is installed, the system does NOT

have to be bonded.

Any new or additional CSST piping requires bonding.

If the system has been previously bonded and inspected by the electrical inspector and

they are adding or modifying the existing system, no additional bonding is required.

Combustion air is needed to achieve the most complete combustion from natural gas.

Type of Space Confined — a space where the volume is less than 50 cubic feet

per 1,000 BTU’s per hour of the total combined input rating of all the appliances located in that space.

Unconfined — a space where the volume is not less than 50 cubic feet per 1,000 BTU’s per hour of the total combined input rating of all the appliances located in that space. Rooms without doors directly connected with the space where the appliances are located are considered to be part of the unconfined space.

Gas Pipe Sizing




NFPA 54 2002 Edition How to Calculate Gas Pipe using the longest run method


NFPA 54 2002 Edition C.3.1 The Longest Length Method. This sizing method is conservative in its approach by applying the maximum operating conditions in the system as the norm for the system and by setting the length of pipe used to size any given part of the piping system to the maximum value. To determine the size of each section of gas piping in a system within the range of the capacity tables, proceed as follows. (Also see sample calculations included in this annex.) (1) Divide the piping system into appropriate segments consistent with the presence of tees, branch lines, and main runs. For each segment, determine the gas load (assuming all appliances operate simultaneously) and its overall length. An allowance (in equivalent length of pipe) as determined from Table C.2.2, shall be considered for piping segments that include four or more fittings. (2) Determine the gas demand of each appliance to be attached to the piping system. Where Table 12.1 through Table 12.23 are to be used to select the piping size, calculate the gas demand in terms of cubic feet per hour for each piping system outlet. Where Table 12.24 through Table 12.33 are to be used to select the piping size, calculate the gas demand in terms of thousands of Btu per hour for each piping system outlet. (3) Where the piping system is for use with other than undiluted liquefied petroleum gases, determine the design system pressure, the allowable loss in pressure (pressure drop), and specific gravity of the gas to be used in the piping system. (4) Determine the length of piping from the point of delivery to the most remote outlet in the building/piping system. (5) In the appropriate capacity table, select the row showing the measured length or the next longer length if the table does not give the exact length. This is the only length used in determining the size of any section of gas piping. If the gravity factor is to be applied, the values in the selected row of the table are multiplied by the appropriate multiplier from Table C.2.4. (6) Use this horizontal row to locate ALL gas demand figures for this particular system of piping. (7) Starting at the most remote outlet, find the gas demand for that outlet in the horizontal row just selected. If the exact figure of demand is not shown, choose the next larger figure left in the row. (8) Opposite this demand figure, in the first row at the top, the correct size of gas piping will be found. (9) Proceed in a similar manner for each outlet and each section of gas piping. For each section of piping, determine the total gas demand supplied by that section. When a large number of piping components (such as elbows, tees, and valves) are installed in a pipe run, additional pressure loss can be accounted for by the use of equivalent lengths. Pressure loss across any piping component can be equated to the pressure drop through a length of pipe. The equivalent length of a combination of only four elbows/tees can result in a jump to the next larger length row, resulting in a significant reduction in capacity. The equivalent lengths in feet shown in Table C.2.2 have been computed on a basis that the inside diameter corresponds to that of Schedule 40 (standard-weight) steel pipe, which is close enough for most purposes involving other schedules of pipe. Where a more specific solution for equivalent length is desired, this may be made by multiplying the actual inside diameter of the pipe in inches by n/12, or the actual inside diameter in feet by n. N can be read from the table heading. The equivalent length values can be used with reasonable accuracy for copper or brass fittings and bends although the resistance per foot of copper or brass pipe is less than that of steel. For copper or brass valves, however, the equivalent length of pipe should be taken as 45 percent longer than the values in the table, which are for steel pipe.

NFPA 54 2002 Edition How to Calculate Gas Pipe using the longest run method



NFPA 54 2002 Edition How to Calculate Gas Pipe using the Branch method


C.3.2 The Branch Length Method. This sizing method reduces the amount of conservatism built into the traditional Longest Length Method. The longest length as measured from the meter to the farthest remote appliance is only used to size the initial parts of the overall piping system. The Branch Length Method is applied in the following manner: (1) Determine the gas load for each of the connected appliances. (2) Starting from the meter, divide the piping system into a number of connected segments, and determine the length and amount of gas that each segment would carry assuming that all appliances were operated simultaneously. An allowance (in equivalent length of pipe) as determined from Table C.2.2 should be considered for piping segments that include four or more fittings. (3) Determine the distance from the outlet of the gas meter to the appliance farthest removed from the meter. (4) Using the longest distance (found in Step 3), size each piping segment from the meter to the most remote appliance outlet. (5) For each of these piping segments, use the longest length and the calculated gas load for all of the connected appliances for the segment and begin the sizing process in Steps 6 through 8. (6) Referring to the appropriate sizing table (based on operating conditions and piping material), find the longest length distance in the first column or the next larger distance if the exact distance is not listed. The use of alternative operating pressures and/or pressure drops will require the use of a different sizing table, but will not alter the sizing methodology. In many cases, the use of alternative operating pressures and/or pressure drops will require the approval of both the authority having jurisdiction and the local gas serving utility. (7) Trace across this row until the gas load is found or the closest larger capacity if the exact capacity is not listed. (8) Read up the table column and select the appropriate pipe size in the top row. Repeat Steps 6, 7, and 8 for each pipe segment in the longest run. (9) Size each remaining section of branch piping not previously sized by measuring the
