Warranty Exclusion
Warranty is void if the furnace is operated in the presence of
chlorinated vapors, if the airflow through the furnace is not in
accordance with rating plate, or if the wiring or controls have
been modified or tampered with.
WARNING
Hot surface hazard . Can cause severe equipment
damage, personal injury, or death .
