▲! CAUTION

To prevent shortening its service life, the furnace should not be used as a “Construction Heater” during the finishing phases of construction until the require- ments listed in item 9, a-g of the safety section of this publication have been met. Condensate in the pres- ence of chlorides and fluorides from paint, varnish, stains, adhesives, cleaning compounds, and cement create a corrosive condition which may cause rapid de- terioration of the heat exchanger.

▲! WARNING

These furnaces are not approved or intended for instal- lation in manufactured (mobile) housing, trailers, or recreational vehicles.

Failure to follow this warning could result in property damage, personal injury, or death.

▲! CAUTION

Do NOT install the furnace in a corrosive or contami- nated atmosphere.
