FLUE EXTENSION KITS
■CAUTIONS
1.Maximum extendable length
FOR BEST ROOM AIR HUMIDITY, KEEP WATER IN THE HUMIDIFIER TRAY.
•7.0 Metres less 1m per bend to a max 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 2.0 metres. Therefore, pipes exceeding these lengths should be made to drain to the outside by giving their horizontal portions 3˚ or more downward and outward slope.

2. To prevent water condensation
Condensed water may accumulate
here, and cause a blockage preventing combustion.
CAUTION
Never allow the exhaust pipe to sag, as condensed water may accumulate and cause incomplete combustion.
4.Wherever the air intake hose and exhaust pipe run sideways, try to have the exhaust pipe on top (to prevent the air intake hose from sagging onto the exhaust pipe.)
