Modine 56145 Combination Gas Control Pilot Valve Natural Gas

Product Description

The MODINE 56145 is a combination gas control and pilot valve designed for natural gas-fired unit heaters. Operating on 24 volts at 50/60 Hz single phase, it draws 0.430 amps and regulates outlet pressure at 3.5 inches water column with a maximum inlet pressure of 0.5 psi. The valve features a 0.5-inch connection and serves as a direct OEM-style replacement for gas-fired commercial and industrial unit heaters. Installation is performed by licensed HVAC technicians or gas service professionals as part of gas control system service or replacement work. This part also carries the alternate part number 5H0806810000.

The MODINE 56145 is used in gas-fired unit heaters across a wide range of residential, commercial, and industrial heating applications. It is suited for suspended and cabinet-style unit heaters in warehouses, garages, loading docks, and similar spaces where direct-fired gas heat is required. Compatible model families span decades of production, including BA, BAE, BAH, BD, BDP, BV, CP, CX, DB, DC, DF, DH, DJ, FX, HB, HC, HD, HF, HP, PA, PAE, PAH, PD, PDP, PV, WB, WD, WH, WS, and related series as listed below.

Installation Notes

Gas valve replacement must be performed by a licensed HVAC technician or qualified gas service professional in accordance with local codes and the IFGC. Shut off the main gas supply and disconnect 24-volt control power before removing the existing valve. Verify inlet and outlet pressure settings with a manometer after installation to confirm regulated output meets equipment specifications. Do not overtighten gas fittings; use an approved pipe sealant rated for natural gas on all threaded connections.
