Utilizing an LP changeover kit ensures that manifold pressure is correctly regulated

Enhanced System Efficiency: Eliminates air and non-condensable gases that cause air binding and reduce heat exchange performance

Reznor 121884 Relay 326058-755 and has a depth ofThe Reznor 121884 Relay is a specialized OEM time delay relay designed for precise sequencing in industrial gas heat sections. Engineered for compatibility with Reznor PDH, RDH, and SDH series models, this 120VAC component ensures critical timing between the ignition cycle and blower activation. By managing the HVAC fan delay, it prevents the delivery of cold air into a space during the heat exchangers warm up phase, while enabling a post purge cycle
