This well engineered, gas water heater has been spe-

cially designed to operate with incoming pre-heated

water:

It operates on the principle of heating water instantaneously

"on demand". When a hot water faucet is opened, cold

water flows through the coils of the heat exchanger in the

Aquastar. This same flow opens the gas valve, and the

burners are ignited by the pilot flame. The heat exchanger

coils absorb the heat generated by the burners and trans-

fer heat to the water. When the hot water faucet is shut

off, the gas valve automatically closes and the burners

turn off. Your hot water faucet is an ignition key to turn on

the water heater, giving you control over your hot water

energy use. Each time you turn off your hot water faucet,

you also shut off the water heater. On the Aquastar "S"

model, if the incoming water is colder than the thermostat

setting of the heater, the burners will ignite to heat the

water in order to boost it and maintain it at the tempera-

ture setting. If the incoming water has been pre-heated,

(ie) solar, and this water temperature is warm then the

the burners will modulate down accordingly, or shut down

completely if the temperature is as hot or hotter than the

heater thermostat setting. The Aquastar 125 BS is the

perfect backup to a solar hot water system.

FEATURES

- High Quality Materials for Long Working Life.

- Copper heating coils for endless supply of hot water.

- Burner output proportional to hot water flow demand

for maximum energy efficiency.

- Automatic Thermostatic Control for steady hot water

temperature

- Input BTU's modulate to zero to prevent overheating of

water from pre-heat source

- Safety thermocouple at pilot burner.

- Automatic overheating protection shut-off sensor.

- Stainless steel burners with stabilized blue flame.

- Built-in corrosion resistant draft inducer.

- Compact space saver: mounts on a wall with two hooks.
