The maximum length of exhaust flue is less than 3m and the curvature should be
limited to two places.
Intake/exhaust flue should be placed on the wall that connects to the outside.
There should be no dangerous materials or obstructions near intake/exhaust flue.
The wall where intake/exhaust flues are placed should be incombustible interior
material.
The connection part of the exhaust flue should be airtight by inserting a "O-ring"
then sufficiently pushing it through. Please check for any exhaust gas leaks.
Do not use the readily available aluminum wrinkle pipe as extension pipe. Please use
the extension pipe set or extension elbow available at the dealers.
When the exhaust flue goes through the combustible wall (including the flue), or
when it goes through combustible material ceiling, it should be insulated with over
20mm of incombustible material and keep at least 50mm from any combustible
materials.
The Air intake hose connection portion should be held together with wire clamp to
prevent any damages to the supply pipe.
In the exhaust flue or exhaust elbow connection portion, insert "O-ring" then connect
it so that it does not disconnect and allow any exhaust gas leaks.
Intake/exhaust top parts should be installed on the same wind pressure panel and
prevent any exhaust gas reverse currents.
Cleaning of the Intake/exhaust flue should be done after turning off the boiler and
cooling the pipes.
Do not use aluminum wrinkle pipe for supply pipe hose. Please use approved plastic
wrinkle pipe.
When connecting the intake/exhaust flue elbow and the boiler pipes, you must user an
"O-ring" to prevent any exhaust gas leak.
