Featuring the MPCI Controller and Auto-Draft® VSAD-Series Inducers and VSUB-Series Universal Blowers

Problem: Erratic draft is the most common cause of heater performance and operation problems. Traditional chimneys cannot adjust to varying winds, temperatures, building pressures and burner firing rates. A chimney has even a tougher time providing stable draft when it is serving multiple heaters. Fan assisted and condensing heaters have specific draft requirements that are not as forgiving as atmospheric heaters.

Solution: Specify the MPCI Controller to automatically monitor and modulate the speed of either VSAD-Series Inducers or VSUB-Series Universal Blowers to maintain optimum draft. MPCI controlled draft systems feature 100% modulation. Add another MPC-Series controller to modulate a separate combustion air blower and/or control a motorized combustion air louver. Vent heaters hundreds of feet in any direction.
