Patent abstract
A leak detector for an insulated duct carrying pressurized hot air comprises a cover secured over a circumferential cut in the insulation of the duct, or over a joint connecting duct sections, thereby creating a reservoir of hot air which has leaked from the duct or joint, a manifold block defining a conduit therein in communication with the hot air reservoir and a cap for securing heat sensitive wires to manifold at the end of the conduit such that the hot air from the hot air reservoir impinges directly on the heat sensitive wires. The leak detector includes flow control mechanisms in the body of the manifold block, to prevent false alarms arising from nominal leakage resulting from ordinary operation of the duct system.
