FOGATTI Natural Gas Tankless Water Heater, Indoor 4.0 GPM, 90,000 BTU Instant Hot Water Heater, InstaGas Classic 90 Series








Key features
- •【Smaller size and better performance】It is only 1/4 the size of a 50 gallon tank water heater, yet it produces approximately 4.0 GPM of hot water through 90,000 BTU for both bathroom and kitchen hot water demand. The highly integrated components also provide greater safety from water pressure surges without the need to install an expansion tank.
- •【Fast and endless supply of hot water】The heat exchanger quickly heats the water to a maximum of 140℉ in a short time, and the hot water is quickly piped through to the shower and tap. No need to wait for the water temperature to heat up slowly like a tank water heater. After that it continues to operate at approximately 4.0 GPM for 40 minutes, which is enough time to produce almost 160 gallons of hot water.
- •【Stable and comfortable temperature】Benefiting from the calculation and control of the heating power 1000/s by the chip, the temperature difference of the water can be precisely controlled within ±2°F.
- •【High compatibility and easy installation】Most tank water heaters have exhaust vent, water and gas pipe that can be universally used in tankless, requiring only a simple re-layout. If installing a tankless water heater in a new house, its compact size makes it easy to install. Of course, we recommend that all installations are carried out in accordance with local building and plumbing codes by licensed professionals.
- •【Excellent quality and service】CSA certification in the USA and Canada. Superior safety and durability using the world's most advanced technology. FOGATTI provide 5 years warranty on heat exchanger and 2 years warranty on other parts.

Really fast delivery. Arrived 1 week earlier than expected

I suggest taking the time to remove the 4 screws holding the front panel- 2 on top and 2 on bottom.
The fan plug was not plugged in and of course, the system wouldn't fire up until I discovered that it wasn't, and I connected it. I'm suggesting inspecting the wiring etc. inside.

Great Value! Save money monthly!

The unit was delivered quickly and in sound condition. 2 hour installation, including tool hunts. Saving $38 a month on heating water! Nice and easy to adjust control panel with L.E.D. display. Best part was the price. Cost was HALF the cost of a 40 gallon gas fired water tank! Size is just right. There are six of us. We have three showers, two bathrooms, kitchen with dishwasher, and a clothes washing machine. The unit provides 130 degree endless hot water in about 8 seconds! Extremely recommended for new or replacement for tank models.
So Far, So Good

I've had this installed for a couple of months now and it is working fine. We had one power outage and I had to go out and touch the touch screen to get it to come back on but other than that it has worked without a hitch. Installing it was easy. It hung on 2 screws with a supplied template, then I added two at the bottom. Literally just connect the incoming cold water, outgoing hot water, and the gas line, and plug in the electrical cord. All were already there as this was a replacement. If you are going from a tank type to this, you might need additional piping or adapters but for me, all the existing pieces connected so there was no looking around for parts or trips to the hardware store. This is an indoor unit so it connects to a flue (or needs a flue) and I did replace the elbow that connected to the flue as my old one was rusty but it was a typical size and was no issue.
GREAT GENERATOR

This unit was delivered exactly as promised! Easy to get set up and operate and runs very quiet. Very excited to put to good use if an emergency manifests! They need to mention in setup process that the single quart of oil is not enough so it is necessary to purchase addition quart of 10w30 oil to bring it up to level.
Never ending hot water
