FG2-15	202	Revises definition of “Appliance.”

The revision will ensure that all of the IFGC's
general appliance installation requirements are also applied to residential CNG equipment. The change would also correct an inconsistency in the current IFGC where Sections 413.2.3 and 413.4 currently refers to this equipment as appliances

Cost Impact: Will not increase the cost of construction.
The change does not impact appliance installation costs for those already covered by the definition.	Same as change between 2015 IFGC, 2018 IFGC and 2017 FGC	No action is needed

Short lengths of steel pipe that are cut from longer pipe stock where the stock has identification markings. It is common practice to cut short lengths of pipe from longer pipe stock. In those cases the identification marks may not appear on the cut pieces.  The code change was further modified by the Committee to remove the limitation for pipe to be cut and threaded in the field, because such operations can occur in other locations such as fabrication shops.

FG40-15	623.2	Revises section 623.2 Prohibited location to allow for cooking appliances listed and labeled for commercial use to be installed in a dwelling unit or within any area where domestic cooking operations occur with the exceptions of appliances that are also listed as domestic cooking appliances or where the installation is designed by a licensed Professional Engineer, in compliance with the manufacturer's installation instructions.  The code change was further modified by the Committee to make sure that the manufacturer’s installation instruction are adhered to in addition to the design requirements specified by the engineer.

Cost Impact: Will not increase the cost of construction.
The installations currently do occur under 105.2 and therefore no new code requirement is being proposed that would increase cost of installation.	Same as change between 2015 IFGC and 2018 IFGC

FG43.15	202	Revises definition of “Piping.”

The proposal removes brass because brass is a copper-alloy and copper-alloy is the term used to identify materials manufactured where copper is the base metal and includes brass and bronze.

Cost Impact: Will not increase the cost of construction.

This proposal will not increase the cost of construction as this change is only to update the name of a material that is already in the code.
