This well engineered, tankless gas water
heater has all the features a water heater
should have:
The instantaneous principle of heating water is
very simple. Cold water enters the heater when
a hot water faucet is opened. This flow of water
causes the gas valve to open. Gas flows to the
burners and is ignited by the pilot flame. The heat
exchanger then absorbs the heat generated by
the burners and transfers it to the cold water as it
travels through the heat exchanger. When the hot
water is turned off, the gas valve automatically
closes and the burners shut off. Your hot water
faucet is an ignition key for hot water. You now
have complete control over your hot water energy
use. [See pages 22-26 for detailed Description
of Operation and Parts Layout Diagrams].
