What is the meaning of BTU? - Pentair Minimax Ch 400,000 Btu Propane Pool Heater Millivolt Ignition

The "048" in the model number means that it is a 4 ton unit...12,000 btu /ton... it is a 48,000 btu unit, so it is a 4 ton unit...

Look for the second cluster of digits of the model number. It will be a number divisible by 6 or 12, and represents the nominal BTU of the system in thousands. A ton of air conditioning equals 12,000 BTU, and 24 divided by 12 equals 2, so the data plate below indicates the system is 2 tons.Mar 20, 2019

How may tons is my Ruud air conditioner or heat pump? - and ...

Its sign of you air con filter has been dirty need go clean it .

Ton is a measure of cooling only when buildings were cooled by ice and how many tons of ice they would use in 24 hours.
British Thermal Units (BTU's) is also a measure of cooling as well as heating in 1 hour.
1 ton equals 12,000 BTU/hr and 1 watt equals to 3.41214 BTU/hr.

The letters BTU means British Thermal Units.

Hi,

no. the flame should be behind the cone. If it passes the cone, this means that there is too much air. simply turn the air pressure screw until the flame no longer comes beyond the cone.

3 ton unit the 36 in the numbers means 36 thousand btu 12 thousand btu per ton

Hi,
I found this explanation which I certainly couldn't improve on.

The British thermal unit (BTU or Btu) is a traditional unit of energy. It is approximately the amount of energy needed to heat one pound of water one degree Fahrenheit. One Btu is equal to about 1.06 kilojoules. It is used in the power, steam generation, heating and air conditioning industries. In scientific contexts the BTU has largely been replaced by the SI unit of energy, the joule (J), though it may be used as a measure of agricultural energy production (BTU/kg). It is still used 'unofficially' in metric English-speaking countries (such as Canada, the United Kingdom), and remains the standard unit of classification for air conditioning units manufactured and sold in many non-English-speaking metric countries.
In North America, the term "BTU" is used to describe the heat value (energy content) of fuels, and also to describe the power of heating and cooling systems, such as furnaces, stoves, barbecue grills, and air conditioners. When used as a unit of power, BTU 'per hour' (BTU/h) is understood, though this is often abbreviated to just "BTU".
