The Pentair Bolt Down Kit (42001-0085S) is the OEM replacement mounting hardware kit for securing Max-E-Therm and MasterTemp pool and spa heaters to a fixed pad or base surface.
⚠️ IMPORTANT: KIT LISTING
This listing is a complete Bolt Down Kit — all mounting hardware components are included as a set. This is not a single bolt or bracket sold individually.
⚠️ IMPORTANT: LICENSED PROFESSIONAL INSTALLATION 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.
This kit provides the hardware necessary to anchor a Max-E-Therm or MasterTemp heater to its installation surface, preventing movement or displacement over time. A properly secured heater protects gas and electrical connections from stress and vibration, reducing the risk of connection fatigue or damage at the heater base.

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment's manual or on the original part itself before ordering.
Pro Tip
Before ordering, confirm your heater's model number on the rating plate affixed to the unit — this is typically located on the side or rear panel. The fit notes for this kit reference Max-E-Therm heaters specifically; if your unit is a MasterTemp, verify against your equipment manual that this kit is the correct hardware for your installation configuration before ordering.
