Caution:
1. When ventilating a room that use combustion equipment with a chimney, provide a suction port large enough.
The size of the suction port should be decided by the instruction of the combustion equipment. (Exhaust gas may
reverse into the room, which may cause carbon monoxide poisoning.)
2. For an exhaust duct to outdoor, attach a pipe hood to the end and keep at least a 1/100 slant downward. (To
prevent rain or frozen water entering.)
3. Heat insulation should be taken if there is dewfall outside of the adapter and frame when indoor heating in winter.
