No pilot light on this model I have the same, it should ignite on start up.
Check the fan runs there is a differential pressure switch across the fan this will prevent the boiler operating if flow of air out of the flue is not proven.
Easy way is to go outsdie and see if unit is lowing when boiler should be firing, Run the hot tap.
There is a definate igition click from the spark unit can you hear this.
And finally is the gas switched on!!!
Good Luck
