Tankless Gas Water Heater Question
Just moved into a Condo which has a gas tankless hot water heater (my first tankless water heater). The Condo's Rules & Regs require residents to turn off the main water line to their Condo when the leave on an extended trip. Do I need to do anything regarding the tankless heater if the water supply is shut off? I don't see where it has an on/off switch and there is no breaker in the electrical panel that's dedicated to the tankless heater. In case it's relevant, the tankless heater is a Takagi T-K3.
Thanks in advance for your responses.
