Heat Exchanger Cleaning; Blower Removal - Dettson AMP1-IE2 Guide D'installation Et Manuel Du Propriétaire

When thermostat is satisfied, the burner blower
continues to run during a post purge period

the instruction on the control for post purge period

This furnace should never be operated without air
filter. Disposable filters should be replaced at least
once a year. If equipped to provide cooling, filters
should be replaced a minimum of twice a year.
To avoid personal injury, make sure the electrical
supply power is "OFF" before servicing.
WARNING
Before performing any service functions,
unless operations specifically require the
power to be on make sure all utilities are

The procedure for
replacement is outlined in the oil burner instruction
manual which came with the furnace.
After replacement of the nozzle, the burner should be
adjusted in accordance with the "COMBUSTION
CHECK" section of the instructions.
