Washington State Energy Code reference:
603.10.3 89sling. All ducts, air handlers, filter boxes, and building cavities used as ducts shall be sealed. Joints and seams shall comply
with Section M1601.3 of the International Residential Code or 603.9 of the International Mechanical Code. Duct tightness testing shall be
conducted to verify that the duds are sealed. A signed affidavit documenting the test results' hall be provided to the jurisdiction having
authority by the testing agent. When required by the building official, the test shall be conducted in the presence of department staff.
Exceptions: 1. Duct tightness test is not required if the air handler and all ducts are located within conditioned space.
2. Duct testing is not required if the furnace is a nondirect vent type combustion appliance installed in an unconditioned space.
A maximum of six feet of connected ductwork in the unconditioned space is allowed. All additional supply and return ducts
shall be within the conditioned space. Ducts outside the conditioned space shall be sealed with a mastic type duct sealant and
Insulated on the exterior with R-8 insulation for above grade ducts and R-5 water resistant insulation when within a slab or
