eF Series® Optional Equipment Features: Maxitrol Gas Pressure Regulating valve— Ensures proper supply pressure to eF unit of 7" to 11" W.C. (provided incoming pressure is between 1/2 and 2 psi). This can be ordered as a separate part, or as part of the heater. For the separate part, please use p/n 243-45517-00 Intake/ (not available for use with the EF-100T-399). Combustion Rain Cap Air Low Gas Inlet Pressure Option—Pre-assembled to allow operation at lower inlet natural gas pressure. Vent Exhaust Concentric Vent Terminal Kit—3" termination fitting provides for only one exit opening through 36 1/4" wall or roof (p/n 239-44069-01).
