NOTE − Flue gas may be acidic and may adversely affect some building materials. If flue gases impinge
on the building materials, a corrosion−resistant shield should be used to protect the wall surface. The
shield should be constructed using wood, sheet metal or other suitable material. All seams, joints, cracks,
etc. in affected area, should be sealed using an appropriate sealant.
