Refer to page 5.
The following are conditions that are normal or easily remedied :
§ OPENING HOT WATER SUPPLY VALVE A SMALL AMOUNT WON'T START UNIT :
The burner of this unit cannot be ignited unless minimum water flow about 0.45 G/min is
maintained. Open up faucet wider.
§ HOT WATER TEMPERATURES CAN VARY WITH MULTIPLE FAUCETS OPEN :
When hot water is used from two or more faucets simultaneously, the amount and
temperature of hot water from each faucet could vary depending on piping scheme and how
much each valve is opened. This tendency could be enhanced when shower and another
faucet are put to service simultaneously.
§ HOT WATER APEARS OPAQUE :
Hot water might look white and opaque during initial outflow, because air mixes with
water in heater, and under pressure is released to atmosphere when faucet is opened.
When this happens, air and water come out in the form of bubbles, looking white. There is
no harm in this process, and hot water will soon turn transparent.
| SOUND OF FAN MOTOR STILL AUDIBLE AFTER UNIT IS TURNED OFF :
Fan motor continues to run for about 150 seconds after unit is turned off in order to drive
exhaust gas out of combustion chamber.
-14-
•
BURNER OPERATES IN REPETITIVE RUN/STOP CYCLE :
This is normal if flow is low.
This unit is being controlled by micro-processor to maintain steady outlet temperature.
• WHITE VAPOR RISING FROM FLUE (IN WINTER)
Vapor in exhaust gas could turn into droplets in winter, which may come out from flue in
the form of white vapor.
• UNIT OCCASIONALLY DISPLAYS AN ERROR CODE "4" AFTER REFILLING FUEL
TANK :
Error code "4" may start blinking, a sign of air being in fuel supply pipe after filling a
empty fuel tank.
Follow the procedure provided on page 5 for air purge. Then, set the hot water supply
temperature adjustment on the control panel on "High". Fully open the water supply
valve, and press "Power" switch once again. Allow unit to run for 10 to 15 minutes after
it moves into "Continuous Operation" mode to make sure that there is no air remaining in
pipe. Do not allow fuel tank to become empty.
• ONLY LUKEWARM WATER IS SUPPLIED IN THE BEGINNING :
This can happen especially in winter or when the unit that has been installed with a long
hot water supply piping arrangement. When standing water in pipe is purged, the
temperature of hot water will become constant.
DETECTION OF TROUBLES BY READING CODE INDICATOR :
1. Code indicators on control panel can tell where trouble is.
2. If service of your local dealer is needed, provide information on code signs.
( CODE SIGNS )
" 4 " Burner does not ignite. Flames stall occasionally. Cds has a broken wire. (Refer to page
