Abstract: This concept is very new, and it will allow for safe and continuous operation of gas heating units when the induced draft fan no longer operates. This device will allow the HVAC service technician to continue to operate the gas heating unit until the proper replacement induced draft fan can be acquired and installed on the gas heating unit. This invention is a supplemental induced draft fan that will attach to the exhaust output side of a gas heating units inoperable induced draft fan to draft air through the heat exchanger and create a vacuum to the pressure switch at a rate to be regulated by a control switch to make the gas heating unit operate safely until the correct part is acquired and installed.
