it is backwards compatible with 370V systems

This 1/8" NPT brass automatic vent limiter is engineered specifically for use with Maxitrol 325-3 and 325-3L series regulators

Precise Pressure Control: Specifically calibrated for a 5" to 15" water column range to meet demanding industrial specifications

Its primary function as a safety limit control is to protect the blower motor and heat exchanger from thermal stress caused by restricted airflow or mechanical failure

This SPST furnace rollout switch is engineered to interrupt the burner circuit when it detects excessive temperatures caused by poor drafting or flame rollout conditions

Robertshaw 10-166 Pilot Orifice it is backwards compatible withThe Robertshaw 10 166 is a high precision LP gas pilot orifice engineered specifically for the 1810 100 Uni Pilot Kit and 1800 1810 series (2B, 2BLC, 9B) pilot assemblies. Featuring a fixed . 011" orifice size, this component ensures a consistent and stable pilot flame crucial for the reliable ignition of main burners in commercial cooking and high demand HVACR systems. It is designed to interface seamlessly with 1 4" pilot tubing, providing a gas
