Questar Gas - Good Practices for Gas Piping and Appliance ...

GREEN STICKER
The proper installation and adjustments of a natural gas appliance
is the responsibility of the installer. This book contains tables listing
the Btu content (heat value) and specific gravity of gas, deration
factors and altitudes throughout Questar’s service area. When
natural gas space heaters (furnaces, boilers, etc.) and water heating
equipment installations have been completed and properly adjusted
for the heat value of the gas and derated for altitude according to
the manufacturer’s installation instructions, the installer shall fill
out and post a “GREEN STICKER” on the appliance where it will
be visible by the customer. The green sticker is an identifier which
will let the customer or a repairman know that the appliance has
been properly adjusted.
Effective July 1, 2002, any contractor installing or servicing natural
gas appliances in Utah must have a Natural Gas Technician
Certification identification with them on the job site. Currently, the
certification is not required by Journeyman Plumbers. For further
information, contact Rocky Mountain Gas Association.
