SAFETY
IMPORTANT NOTE: After completing the servicing or replacement of components always:
1. Test for gas soundness.
2. Test the burner manifold anges for soundness. This can be done with leak detection spray whilst
operating the boiler. The gas valve and controls must be shielded from the spray.
3. Check the water system is correctly lled and free of air. Air in the boiler could cause damage to
the heat exchanger. For this reason a non-isolatable automatic air vent is tted as standard on
all FHE boilers.
4. Check the module cover panels are correctly tted.
5. With the system hot examine all water connections for soundness.
