OPERATING SEQUENCE

1.

  Check that the system has been filled and the boiler is not air locked - 

air in the boiler could damage the heat exchanger.  For this reason the 

airvent located in the left top side must never be shut off.

2. 

Check that all the drain cocks are closed and any valves in the flow 

and return are open.

3.

  Check that the GAS SERVICE COCK IS ON.

4.

  Fill the condensate trap with water before putting the unit into operation 

(see Frame 58 for condensate trap removal).  

5.

  Check the indication on the pressure gauge.  If the pressure is less 

than 1 bar the installation should be filled up first (sealed system only).

6.

  Switch the electricity supply ON and check that all 

the external controls are calling for heat.  Check 

boiler is set for winter operation - see Evomax user 

interface basic operating instructions.

7.

  The boiler will commence the ignition sequence.  If 

after 5 attempts the boiler has failed to light then it 

will lock out.  Press the reset button to restart the 

ignition sequence.

8. 

Operate the boiler for 10 minutes and check the gas 

rate (Table 1).  You should be able to read at least 

90% of the nominal.
