Smoke and smell come out from
the Unit
Floor and wall covering and/or dust may be burning.
Ventilate the room for about 10 ~ 15 minutes to let
smoke and smell go out and bring your heater to
SAV.
Electromagnetic pump makes jit-
tering sound, or flames are not
stable.
Unnecessary air bubble may arise in the pumping
system. As air bubble disappears, flames will be sta-
ble.
After repeating ignitions and ex-
tinguishments, fuel gas over
flows to accidentally put out
flames, or emits smell.
Sufficient fuel may not have reached the burner unit.
If error code "E1" is indicated on the digital indicator,
press <OFF> key first, then <ON> key.
Sometimes small sounds comes out.
Sounds are caused by metal expansion and con-
traction.
They are all normal.
The Unit does not reignite instantaneously
once extinguished.
It requires 1 to 2 minutes of preheating.
