an aftermarket permanently located, manufactured (mobile) home, where not prohibited by local codes.
This appliance is only for use with the type of gas indicated on the rating plate. This appliance is not
convertible for use with other gases.
The appliance is equipped with two catalytic tiles which are designed to fi lter out harmful gases and limit
carbon monoxide output. It is likely that with the appliance in operation, the catalytic tiles will actually scrub
the carbone monoxide normally found in the room and reduce it to a lower level. The tiles must not be altered
or removed. Do not operate the appliances when using products such as paint, paint thinner, adhesives, etc.
These products will permanently affect the catalytic tiles’ ability to scrub the air.
Expansion / contraction noises during heating up and cooling down cycles are normal and are to be expected.
