Is this 30,000 BTU or 20,000 BTU? Under the Specs it shows: 20,000 BTUs In the name of the product it says 30,000 BTU

Asked by: The German Grappler
All vent free are available in 10, 20, and 30 thousand btu units. The part number is the key to knowing what is in the box or the model number. There will be only a 10 20 30 in the model number. So it sounds like you are getting a 30 btu unit. Call us if you need further help. Rich Mr Heater

Will it operate off of a 250 gallon tank

Asked by: leroy863
They will with the right connections. Technically our heaters are designed with 20 and 40 pound containers in mind.

How difficult are they to install for a fairlyvadept layman?

Asked by: Hal51
Pretty much if you can turn a screw you can install a vent free heater for the wall or floor. The "feet" are attached by screws. Rich Mr Heater

Can these heaters run 24/7 I use my 35 foot camper in the winter allot

Asked by: Pjg69
Yes... if needed when connected to a big tank and safety regulations and rules are followed. Test the alarms, and provide some venting. Moisture from the combustion does condense on RV windows readily. Rich Mr Heater

The name of this says "Propane" use, but in the summary and specs, it says "Natural Gas". Does this means "both" can be used with this machine?

Asked by: Jose I
No, these units are either purchased as a natural gas unit or a propane unit and are not convertible.
