Re: Revised Emergency Gas Code Regulation

Attached for information only pdf format of 110105_new_revised_gas_reg_attachment.pdf
, is a copy of a revised emergency gas regulation that became effective on October 6, 2005. The regulation applies to the installation of side walled horizontal gas fueled equipment in residential occupancies. This regulation is to be enforced by the local plumbing/gas inspector. We would encourage fire officials to work with the gas/plumbing officials when they have questions regarding carbon monoxide detector placement and installation.

Highlights from the new regulation require licensed plumbers/gas fitters:

  • Comply with CO requirements for installations that have sidewall vents less than7ft high.
  • Install a hard wired carbon monoxide detector within 30 days of equipment installation (a battery operated detector may be used in the interim).
  • Determine an alternative location in the event the heating unit is located in an attic or crawl space. In that case, the CO detector is placed in the next adjacent habitable floor level.
  • Recognize exempted equipment in accordance with CH. 10 of NFPA 54.

Once Nicole's law has passed, this statutory CO legislation may require further revision of the regulation. The Board of Fire Prevention Regulations will work with the gas/plumbing board to reconcile both regulations going forward.
