NEW CONSTRUCTION
The operation of gas furnaces in a construction environment
can cause a variety of problems with the furnace. Before
occupying the residence, homeowners should have these
safety inspections performed by a licensed technician:
• The fi lter must be replaced or cleaned and the furnace
must be inspected by a licensed HVAC technician. The
furnace must be cleaned and/or repaired if found to be
dirty, damaged, or malfunctioning in any way. Before
occupancy, the furnace shall be inspected and ap-
proved by applicable local authority even if this results
in redundant inspections.
• The duct work must be inspected and cleaned if found
to contain any construction debris.
FURNACE AND AIR DUCTS
Homeowners should perform frequent visual inspections
of the furnace for obvious signs of deterioration. The
furnace should be sound without sagging, cracks gaps,
etc around the base. The return air duct connection(s) is
secured and sealed to the furnace cabinet and terminates
outside the area containing the furnace. Any signs of
damage or loose connections should be repaired by a
qualifi ed HVAC technician.
