when installing your water heater:
GENERAL
The T-KD20. Water Heater is an
instantaneous, tankless water heater designed
to supply endless hot water to your entire
household and/or commercial facility utilizing
total efficiency. The principle behind the T-
KD20 Water Heater is simple. Once you open
a hot water tap, water flows through the T-
KD20 Water heater. Once a minimum of 0.75
GPM is achieved, the flow sensor
automatically commands the computer to turn
on the fan, activate the electronic igniter and
open the gas valves. The computer monitors
water temperature, water flow rate, and gas
flow to insure that you get the right amount of
hot water at the correct hot water temperature.
After the burners are ignited, the “fire on” lamp
is lit. The computer will modulate the gas
supply valve and water flow 0.75 gallons per
minute is required to turn the burners on;, after
the burners are ignited, the flow rate can be
lowered to 0.6 gallons per minute to maintain
the heater on. It is advisable to increase the
cold tap rather than decreasing the hot tap to
adjust the water temperature. As long as you
have water, gas and electricity, you will get an
endless flow of hot water. Open a hot water tap
to turn on your water heater. Close the tap to
turn off your water heater.
