What model heater do I have?
How to find your heater’s Model Number:
There will be a decal affixed to the side or on the fuel tank of the heater. This decal will state the model number, serial number, fuel capacity, pump pressure, voltage, amps, etc.
If your heater has a plastic fuel tank the number is generally stamped in the plastic
Examples: R100A, R100, RH100VT, RHD125T (There will always be a letter followed by a number and sometimes more letters)
Pro 125 and Pro 165 are examples of what’s NOT model numbers, but are series numbers. Examples of those as model numbers are RH125T or RH165CT.
