and flue connections. The furnace may be installed on
a combustible floor.
Do not install furnace directly on carpeting, tile or other
combustible material.
The furnace must be installed level for safe quiet
operation.
CAUTION

atmosphere containing chlorine, fluorine or
any other damaging chemicals. Refer to Part
