Durable Construction: Manufactured from corrosion-resistant aluminum to withstand standard gas contaminants and environmental factors

Using a rating lower than 189-227 MFD may result in insufficient torque

System Stability: High-gauge steel construction prevents warping under the extreme temperatures of the heat exchanger header

If your water heater uses extra-thick foam insulation (up to 3")

this wrot copper pressure fitting is designed to handle the high operating pressures of R-410A

Lennox 13H28 Transformer Els PW 17895 Durable Construction: Manufactured from corrosion-resistantThe Lennox 13H28 Transformer is the designated OEM replacement for 51M4401, engineered for high demand HVAC control voltage applications. Designed by Basler Electric (Model BE28868001), this 70VA transformer handles a primary input of 208 240V AC and steps it down to a stable 24V secondary output. This component is critical for powering low voltage control circuits, indoor air handlers, and packaged unit control boards. It features a robust 3. 5 Amp
