Will this work on propane?

No. It is designed exclusively for LNG, so it needs a natural gas supply. A propane setup requires a different unit or a conversion kit the maker does not list.

How many fixtures can it run at once?

It is rated for two to three points of use at the same time, such as a shower plus a kitchen sink. Running more than that at once will split the hot water and drop output.

What water pressure does it need?

It can operate on as little as 3.6 PSI, which suits low-pressure or gravity-fed supplies. Check that your line stays above that when other taps are open.

What venting does it require?

It uses a 2.5-inch horizontal vent pipe and needs a smoke exhaust pipe with proper ventilation to the outdoors. Route it per local code before mounting the unit.

Can I install it myself?

The fittings are standard 1/2" NPT, but it is a gas appliance. Most buyers should have a licensed plumber or gas fitter handle the gas line, venting and final checks.

What temperature range can I set?

The LED display adjusts output from 95°F to 149°F. The maximum 149°F rise is the most it can add to incoming water, so cold climates reduce flow at high settings.

Our take on the Gray 16L Indoor Gas Tankless Water Heater with Multi-Protection

This is a gray, unbranded indoor tankless gas water heater rated at 16 liters, built for LNG (natural gas) only. It heats on demand at up to 4.21 GPM with a maximum 149°F temperature rise, and the LED panel sets output from 95°F to 149°F. A stainless steel body and oxygen-free copper heat exchanger are meant to resist corrosion and lose little heat. It suits small homes, cabins and apartments running two to three hot-water points, and it takes far less wall space than a tank. Against branded rivals it lacks a known name and certified listings, so venting and gas work should be checked by a licensed installer.
