Frequently Asked Questions
What size pool does a 300,000 BTU heater suit?
It suits large in-ground pools and pool and spa combinations. Sizing depends on surface area, temperature rise, and climate, so have a pool professional size it for your install.
Is the 460735 propane or natural gas?
Liquid propane. Fuel is set by model. Order 460734 for the 300K BTU natural gas version.
Should I choose 300K or 400K BTU?
300K covers most large residential pools on a normal schedule. Step up to the 460737 at 400K if you want faster spa recovery or you are in a colder climate.
Is the MasterTemp Low NOx compliant?
Yes. MasterTemp heaters are Low NOx certified, which is required in California and other regulated air quality districts.
Does it work with pool automation?
Yes. It integrates with Pentair automation systems for remote temperature control, scheduling, and status notifications.
Does it need professional installation?
Yes. Propane sizing, venting, electrical, and local code make this a licensed installer job, and improper installation can affect warranty coverage.
