Boiling Water - Rinnai RUS-51FT Instructions Manual

Check that water is available at the heater before first
ignition. (Turn the control to the " cold" position and push to
check water flow, then push the knob again to stop water
flow, then return it to a hot water position.
Fully open the gas valve on the unit. Do not open any other
gas valve when the room' s gas valve is open.
TO TURN ON: Push the control knob. The burner will
ignite and hot water will flow. Ignition can be checked in the
confirmation window.
TO TURN OFF:Push the button again, and release.
Gas and water will stop automatically.
If the water trickles out a few seconds after the water is
turned off, it is not a fault. Face the hot water outlet pipe
down so the water can flow out straight and the trickling will
lessen.
TEMPERATURE CONTROL
To increase the temperature of the water, turn the control
clockwise, to decrease it, anticlockwise. (The water flow
will decrease as the temperature increases).
CAPACITY CHANGEOVER
When water temperature is high (in Summer etc.) turn the
capacity changeover level to " low" . These will lessen gas
flow and lower water temperature. When water
temperature is low (in Winter etc.) turn the lever to " high" .
This will increase gas flow and increase water
temperature.
COLD WATER ONLY
Turn the control to the " COLD" position, and push the but-
ton. In this case, water flows without ignition. If the control
knob is positioned in any other position, hot water will flow
out. To stop the flow, push the button again.

BOILING WATER

Turn the control to " high" (Summer) or " high" (Winter). Use
the " Summer" positioning when seasonal temperatures are

back slightly.

reached:
" Summer" : Water temperature +=60°C
