fan guard and the fan blades. Use care when
cleaning the fan blades to prevent causing
misalignment or imbalance.
Unit operation
The combustion and correct operation of the
appliance should be verified as a part of the
normal service routine. Follow the steps in
the start up and commissioning procedures to
