Yes, you can vent two oil-fired appliances together with one power venter as long as you size the power venter to handle the maximum input firing rate in GPH (gallons per hour) of both appliances combined. Each appliance would need to use its own control kit. You would wire the power side of the control kits in parallel and “Tee” the pressure switches together. The control side of the control kits, being T1-T3, would be wired to their respective appliance. Also, make sure there is enough combustion air for both appliances firing together.
