No. The unit needs power for its ignition and controls, so plan an outlet near the install.

Is it for indoor or outdoor use?

It is designed for indoor installation with the included vent pipe. Do not run it outdoors or in an unvented space.

What fuel does it use?

Propane (LPG) only. It is not set up for natural gas.

Our take on the Ranein Propane Gas Tankless Water Heater with Vent Pipe

The Ranein is a propane-fired tankless water heater rated at 100,000 BTU and up to 4.3 GPM, with a vent pipe included for indoor installation. It heats water on demand for several taps at once and carries anti-dry-burn, anti-leak and anti-overheat protection. At this output it suits one to two bathrooms in a mild climate, but it is a budget unit: expect a lower flow rate than premium condensing models and less precise temperature control. Owners rate it around 4.2 out of 5, generally satisfied with the value and the hot water delivery.
