DESCRIPTION
RT750 & RT1500 models are supplied with the model PSA-1 Fan Proving Switch which will disable the burner(s) if an Inducer mal-
function should occur and are compatible with Tjernlund UC1 and UCRT interlock controls. The RT750H & RT1500H are supplied with
a wall mount speed control to vary inducer performance in solid fuel applications. The Rooftop Inducer may be used on positive or
negative pressure rated chimneys because the fan creates a negative pressure throughout the entire venting system. Suitable for use
on natural gas, LP-gas, oil-fired, solid fuel heating systems or general ventilation. Also applicable for dryers, gas fireplaces, stoves,
BBQ’s or pizza ovens. The Rooftop Inducer must always be installed outdoors at the vent system termination. Refer to heating appli-
ance manufacturer's instructions regarding specific venting requirements.
GENERAL SELECTION INFORMATION
Selection of a Rooftop Inducer involves determination of the maximum volume of air or gases to be handled, their density and the
maximum static pressure which the fan must overcome. Rooftop Inducer performance needs to be de-rated from 70
O F performance
curves to anticipated air or gas temperatures. Please feel free to contact us for application and model selection assistance by calling
800-255-4208 or email us at [email protected]. Vent layout or other information can be faxed to 651-426-9547.
