Operation

General

The Flash Water Heater is an instantaneous, tankless water heater designed to efficiently supply domestic or commercial hot water. The principle behind the Flash water heater is simple: Once a hot water tap is opened, the Flash’s flow sensor detects that hot water is needed, and automatically commands the computer to electronically ignite the burners, and heat water. During operation, the computer monitors the water temperature and flow rate, and controls the gas flow and fan speed to maintain a constant output temperature. After the burners are ignited the “fire on” lamp will be lit.

3.If necessary, mix in cold water to get a comfortable temperature.

Turning It Off

To turn off the Flash water heater

1.Close the hot water tap, or turn appliance off.

2.Flow will diminish, unit will shut off.

3.“Fire On” lamp will go out.

0.75gallons per minute is required to turn the burners on, but after the burners are ignited, the flow rate can drop to 0.6 gallons per minute without the burners turning off.

As long as water, gas and electricity are connected, there will be an endless flow of hot water. To turn on your water heater, just open a tap. To turn the heater off, just close the tap.

Temperature

The output temperature of the T-K2 has been factory set for a maximum 120° F (50° C). This is electronically controlled by the computer and can be adjusted with a TK- RE01 temperature controller, or with the dipswitches on the computer board (See pgs. 21-22 for dipswitch settings). Further adjustment may be made by mixing in cold water with the hot to obtain the ideal water temperature.

The flow rate possible out of the unit is dependent on the temperature setting chosen. Consult the flow charts on the last page of this unit to determine the possible outlet temperature and flow rate combinations.

WARNING: Temperatures above 125º F (52º

C)can cause severe burns or death from scalding. Children, the disabled and the elderly are at a high risk of being injured. Feel the water temperature before bathing or showering. Do not leave children, disabled persons, or the elderly unsupervised.
