Some of the significant revisions in the 2006 National Fuel Gas Code include expanded pipe sizing tables and new rooftop support requirements; permitting Type B vents to be installed in outdoor insulated chases and revising vent-connector length limits; and new requirements for appliances located in attics, new options for appliance shut-off valve locations, and revised appliance connections.
The National Fuel Gas Code provides criteria on most aspects of fuel-gas installations on consumer premises. Coverage includes gas piping materials, system design, installation and inspections; combustion air; equipment venting; and specific equipment installation criteria.
"The new National Fuel Gas Code is the country's premier model fuel gas installation code," said Paul Cabot, administrator of the National Fuel Gas Code for the AGA.
