Abstract
Radiant tube space heating appliance (FIG.,) has radiation ducting,with one or more inline burners,in a branch or branches,upstream of common tailpipe,. An exhuast fan,in the tailpipe draws heated gases thought the ducting. A power operated control damper,in the tailpipe is actuated in response to sensing of the gas temperature in the tailpipe to reduce the induced flow therein when the temperature is below a certain level to counteract the increased volume throughput of the adjacent fan at lower temperature so that performance burners, e.g. on start up, is not adversely affected.
