9.  Maintenance 

 

To maintain the high degree of efficiency of the unit, it is necessary to service it regularly. Depending on the type 

of operation, annual or semi-annual servicing is recommended. 
The boiler and firing must be inspected by a qualified specialist in accordance with the official regulations. 
Before performing any work on the unit, it must be disconnected from the mains and the fuel supply must be shut 

off. 
The device contains components made of synthetic silicon mineral fibers (ceramic and glass fibers, insulation 

wool). In order to avoid all types of health hazards, suitable clothing and a protective mask must be worn for work 

on or with these components. 

 

 

9.1.  Periodical checks and maintenance operations 

Check manometer with circulation pump off. Low water or pressure level indicates that the system must be 

filled up with water. 

Check that the expansion chambers function properly 

Check safety valves as well as heating and hot water system blowers 

Carry out burner maintenance according to the recommendations given in the burner manual. 

Check fuel oil level 

Clean boiler and chimney 

 

9.2.  Boiler cleaning 

Boiler should be cleaned by your chimney sweeper and engineer. 

 

 

The cylindrical type construction of Ensbury LT boilers makes cleaning much easier to perform. However, we 

recommend that heating surfaces in fuel oil boilers be cleaned with appropriate chemical products. Your 

installation contractor, as an engineer, will know how to best advise you. 

Turn off burner 

Disconnect burner plug from socket 

Loosen boiler door screws and rotate door together with burner till it stops. 

Remove the turbulators 

Clean the combustion chamber and smoke tubes 

Disassemble the lid on the back of the boiler and clean the flue gas collector 

Re-install the cleaned turbulators following the instructions given in chapter 6.6 of these instructions 

Re-install lid and close furnace door 

Start up burner again. 

 

9.3.  Burner maintenance 

The regular maintenance of the burner (body, jet, burner head, igniter, pump filters) must be carried out by a 

qualified specialist in accordance with the instructions of the burner. 
After the work has been completed, the settings of the burner must be checked to ensure that they meet the 

performance requirements of the boiler.
