local code concerning fire prevention. 
 

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.
