About This Item
The Pentair Manifold Kit (460748) is the OEM replacement manifold assembly for the MasterTemp 250K BTU pool heater — specifically the 250NA (natural gas) and 250LP (liquid propane) models. This is a complete kit, not a single component.
⚠️ IMPORTANT: HEATER COMPONENT — PROFESSIONAL SERVICE REQUIRED
Gas and electrical heater components must be serviced by a licensed pool professional or qualified HVAC technician. Do not attempt to service gas or high-voltage components without proper certification.
⚠️ IMPORTANT: COMPLETE KIT — NOT A SINGLE PART
This listing is a kit, not an individual component. It includes Item Nos. 3–14 and 21 from the MasterTemp water system diagram, plus Item Nos. 5–7 from the electrical system diagram — O-rings, insulation, the igniter, and blower gaskets are all included.
The manifold kit services the internal water circuit of the MasterTemp 250K BTU heater, directing pool water flow through the heat exchanger section. A cracked, leaking, or degraded manifold assembly causes water loss, pressure drop across the heat exchanger, and accelerated damage to surrounding components. Replacing this kit restores the full water system to OEM specification in a single service event. Verify part number 460748 against the serial tag and service manual for your specific heater before ordering.

Pro Tip
Cross-reference the item numbers listed on this kit (Nos. 3–14, 21 in the water system diagram; Nos. 5–7 in the electrical system diagram) against the exploded parts diagram in your MasterTemp service manual before beginning disassembly. This confirms every component in the kit maps to your specific heater build. When reassembling, follow the torque specifications in the MasterTemp service manual for all manifold fasteners — under- or over-torquing manifold connections is a leading cause of post-service leaks on this heater platform.
