CAUTIONS
1. Maximum extendable length
FOR BEST ROOM AIR HUMIDITY, KEEP
WATER IN THE HUMIDIFIER TRAY.
2. To prevent water condensation
Condensed water
may accumulate
here, and cause a blockage
preventing combustion.
MAXIMUM FLUE LENGTH 7 METRES.
Reduce length 1 metre for each bend used.
(e.g. 4 metres, 3 bends).
• The bend where the hose and pipes leave
the body is not counted.
• The air intake hose should run along the
exhaust pipe.
3. Condensed water formed by
combustion, will run back to the
unit, and may overflow from the
condensation pan if pipes are
longer than 2.5m. Therefore,
pipes exeeding these lengths
should be made to drain to the
outside by giving their horizontal
portions 75mm or more downward
and outward slope.
CAUTION
Never allow the exhaust pipe to sag, as
condensed water may accumulate and
cause incomplete combustion.
75mm slope(approximate)
Less than 2.5m
