MasterTemp 250 HD ASME: match the fuel and configuration
Pentair 461020 is the natural gas MasterTemp 250 HD ASME pool and spa heater, rated at 250,000 BTU/hr fuel input. The HD configuration has a cupro-nickel heat exchanger.
Exact fuel selection
Natural Gas configuration. Match the gas supply to the heater rating plate.
Configuration matters
ASME-rated model; keep its parts and pressure requirements distinct from non-ASME heaters.
Plan the installation
Gas heating still requires electrical power, suitable water flow and a correctly designed combustion-air and vent system.
Check before ordering
Have a qualified installer verify available gas capacity, electrical supply, water flow, combustion air, venting and service clearances. Installation labor, site-specific venting and automation are separate. Confirm the supplied control generation before relying on smart-automation features.
Installation and service require a qualified pool-heater professional following the complete manufacturer instructions. Improper work can cause fire, explosion, electric shock or carbon-monoxide exposure. Never bypass a safety switch.
