help Rinnai V65iN FAQ
Can the Rinnai V65iN be installed indoors, and does it use natural gas?
Yes. Rinnai identifies the V65iN as an indoor, natural-gas, non-condensing tankless heater for small to medium homes or remodels, with a maximum input of 150,000 BTU. [Rinnai V65iN](https://www.rinnai.us/residential/product-detail/v65in)
How much hot water can the Rinnai V65iN deliver?
Rinnai lists a maximum domestic hot-water flow rate of 6.5 GPM, but that is not a guarantee at every temperature rise. Cold incoming water, target temperature, and simultaneous fixtures determine the flow you actually get. [V65iN specifications](https://www.rinnai.us/residential/product-detail/v65in)
What space and connections does the Rinnai V65iN need?
The unit is about 26.9 inches high, 14.04 inches wide, and 9.27 inches deep, with 3/4-inch gas, cold-water, and hot-water connections. Because it is an indoor gas appliance, the installation also needs approved venting and combustion-air arrangements under local code.

Does the Rinnai V65iN support Wi-Fi?
Rinnai lists the V65iN as Wi-Fi capable, and its UEF is 0.80. Confirm which controller or accessory is required for the specific installation, because Wi-Fi capability does not remove the need for professional gas and vent work.
