10. Securing diagram of Exhaust Pipe and Exhaust Pipe Top installation
NOTE: Put a semi-straight pipe or straight pipe in the Exhaust Pipe fitting hole at first, and
lay transversely.
NOTE: Select a place which is clear of combustible objects within 15 cm around the
Exhaust Pipe Top, and 60 cm in the exhaust direction. And any opening such as the
window or ventilation hole which can blow exhaust gas back indoors is not allowed
on the wall as shown above.
NOTE: Use corrosion and heat resistant steel.
11. Caution in areas of heavy snowall
In a cold-district (heavy snowfall), select a place where the Exhaust Pipe Top is free from
snow. In case the Exhaust Pipe Top is blocked or plugged, exhaust gas may leak indoors
and cause a danger.
NOTE: Clearance between ground surface and Exhaust Pipe Top should be increased as
far as possible to avoid blocking the Exhaust Pipe Top.
