02- 658 C.M.R. ch. 110, § 21 - Welding of non-residential warm air Heat exchangers
1. The manufacturer shall be consulted to
determine whether the welding of a heat exchanger is sound engineering
practice. The manufacturer shall provide a written statement as to the
feasibility of its heat exchanger being welded. If the heat exchanger is no
longer in production, a master licensee shall make a written request to the
Board and obtain written approval from the Board before the repair is
undertaken.
2. The repair of a heat
exchanger by welding shall be performed by a welder in a procedure suitable for
the material. A master licensee shall oversee such repairs.
3. The master licensee shall receive guidance
from the welder as to the feasibility and acceptability of performing the
welding procedure of the metals prior to the repair of any heat
exchanger.
4. After completion of
said repairs or welding, the master licensee shall obtain a written statement
from the welder documenting that the heat exchanger has been welded, tested and
is acceptable for use without leakage of after-products.
5. Written documentation of said repairs or
welding shall be provided to the owner. The original documentation shall be
kept on file by the master licensee who requested the welding. A copy of all
the repair documents containing, at a minimum, the following information shall
be sent to the Board :
A. The name of the
owner and location where the repairs were completed;
B. The name and address of the
welder;
C. Specific area(s) or
location(s) where the repair(s) or welding was performed;
D. Written approval of the repair from the
manufacturer where applicable;
E.
Equipment identification information, i.e., name, model number, serial number
and gross Btu. rating; and
F. The
name, address, and license number of the master licensee who requested the
repair.
6. Welding
repair of a heat exchanger may be performedonly once. A subsequent welding
repair may not be made to a heat exchanger unless a master licensee makes
written request to the Board and obtains written approval from the Board before
the repair is undertaken.
