Chimney Connector
•  Frequency: As necessary / Yearly
•  By:QualiedServiceTechnician/User
At the end of the burn season, brush and clean all sections 
of chimney connector pipe. Some owners remove the 
chimney connector for the off season. Any ashes left in the 
connector pipe will actually draw moisture which promotes 
rust. This is why it is very important to clean all ashes at the 
end of the heating season. 
When cleaning the chimney connector above the appliance, 
keep the bypass damper in the open position. This will keep 
any loosened material from falling into the Firedome Plus 
combustion chamber. 
Chimney
•  Frequency: As necessary / Yearly
•  By:QualiedServiceTechnician/ChimneySweep
The entire chimney should be professionally cleaned at 
least once yearly. It is best to have this done at the end of 
the heating season to be sure all ash is removed. You'll also 
want to inspect the condition of the chimney prior to using 
the appliance, to be sure there are no bird or animal nests.
