Ductwork Configuration
When connecting ducts, insert a canvas duct between the main body and the duct.
• Use non-combustible duct components.
• Install sufficient insulation to prevent condensation forming on outlet duct flanges and outlet ducts.
The contractor is responsible for providing transitions to accommodate difference in sizing between the unit and the building ducts. Duct con-
nections to collar-type openings can be made with S-cleats or overlapping joints. Apply caulk around each duct connection. Failure to seal
duct connections can cause air leakage and system performance problems.
When an air duct which carries supply air or warm air passes through a combustible roof, a clearance of one (1) inch must be maintained between
the outside perimeter of ductwork and any combustible materials, per NFPA Standard 90A.
