The RT750H & RT1500H aresupplied with a wall mount speed control to vary inducer performance in solid fuel applications. The Rooftop Inducer may be used onpositive or negative pressure rated chimneys because the fan creates a negative pressure throughout the entire venting for use on natural gas, LP-gas, oil-fired, solid fuel heating systems or general ventilation. Also applicable for dryers, gas fire-places, stoves, BBQ s or pizza ovens.

4 The Rooftop Inducer must always be installed outdoors at the vent system termination. Refer toheating appliance manufacturer's instructions regarding specific venting SELECTION INFORMATIONS election of a Rooftop Inducer involves determination of the maximum volume of air or gases to be handled, their density and themaximum static pressure which the fan must overcome. Rooftop Inducer performance needs to be de-rated from 70OF performancecurves to anticipated air or gas temperatures.
