Frequently Asked Questions
What is the MasterTemp 125 used for?
It is the smallest MasterTemp and is typically installed on spas, hot tubs, and small pools rather than full size in-ground pools.
What does without cord mean?
The heater ships without a factory power cord and is intended to be hardwired by the installer. If you need the cord version, order 461061 for propane. Confirm the natural gas cord variant with us before ordering.
Is the 461058 natural gas or propane?
Natural gas. Order 461060 for the 125K BTU propane version without cord, or 461061 for propane with cord.
Is it Low NOx compliant?
Yes. MasterTemp heaters are Low NOx certified, which is required in California and other regulated air quality districts.
Can it heat a full size pool?
It will, but slowly. For an in-ground pool, step up to the 460792 at 175K BTU or the 460730 at 200K BTU.
Does it need professional installation?
Yes. Gas sizing, venting, and hardwired electrical make this a licensed installer job, and improper installation can affect warranty coverage.
