upgrading to a 40VA transformer is often recommended for systems with modern smart thermostats or multiple zone dampers that exceed the capacity of original 30VA units

The Sporlan C-083 is rated for a nominal capacity of 0

0 SCFH bleed rate for accurate one-pipe control

The 440V rating indicates the maximum dielectric strength

Reznor 201158 Pressure Switch Els PW 17895 upgrading to a 40VA transformerThe Reznor 201158 Pressure Switch is a critical safety component designed for precise combustion air monitoring in high capacity gas fired unit heaters. Engineered for a setpoint of 1. 10" WC, this SPST (Single Pole Single Throw) vacuum switch verifies that the inducer motor is moving sufficient air to ensure safe venting and combustion before the ignition sequence initiates. This specific model features dual 1 4" barb connections, allowing for
