Tjernlund In-Line Draft Inducers assure positive draft when restricted boilers and furnaces, poor chimneys or negative pressures in buildings prevent proper exhaust of combustion gases. The venturi action starts air moving up the stack instantly & keeps it moving smoothly. These units are quick and easy to install and completely automatic in operation. In-Line Draft Inducers are built for long-lasting, trouble-free service and available in sizes and capacities to meet virtually all heating system requirements. The Vari-Draft control permits adjustment to individual job requirements.
Vents/Chimneys utilizing In-Line Draft Inducers must be vertically terminated above the roof line.
EVERYTHING NEEDED TO CONFORM WITH NATIONAL MECHANICAL CODES
Draft Inducer Model
PS1505 Fan Prover Safety Interlock
UC1 Universal Control
MAC1E/MAC4E Multiple Appliance Control (if applicable)
Fan Prover Safety Interlock Model PS1505
To satisfy national mechanical codes for oil and gas installations, Draft Inducers must be properly interlocked with burner circuits. The PS1505 Fan Proving Switch monitors pressure within the Inducer housing to verify Inducer operation. Used in conjunction with the UC1 Universal Control, it assures compliance with codes and simplifies electrical interlock with all 24/115 VAC burner circuits. The PS1505 is not compatible with millivolt gas valves.
| Chimney Stack Assist Kit for Orphaned Water Heaters | |||
As a result of upgrades to direct vent condensing furnaces, water heaters are often orphaned and left to vent in chimneys that are oversized after the vent connector from the old furnace is capped. This can lead to condensation and flue gas spillage problems. The CSA1 allows a water heater to be vented through an existing vent connector into an oversized chimney without adding a chimney liner.
