MAINTENANCE
Service intervals should be determined during the first months of operation. Details of this procedure can be found
in the Installation Commissioning and Maintenance Instructions for the appliance. If these instructions are not
available, a copy should be obtained from Lochinvar's website
on the back cover of this document.
Even if the maintenance schedule for the storage vessel is determined to be less than annually, it is
important that all controls and safety features are checked for correct operation on an annual basis. The
sacrificial magnesium anodes must be inspected at least once a year unless the Correx non-sacrificial
anode protection system is used, in which case there is no requirement to check the condition of the
sacrificial anodes.
A competent person should check and ensure that the flue system, ventilation to the plant room, safety valve,
drain, pressure gauge etc. are in a serviceable and working condition and still comply with the relevant standards
and codes of practice, as detailed in the Installation, Commissioning and Maintenance Instructions.
1.6
FROST PROTECTION
The LBF water heater has no built in frost protection system. Adequate protection must be provided to prevent the
water heater being exposed to freezing temperatures.
1.7
AIR SUPPLY
When installed in a compartment, the appliance compartment must be ventilated in accordance with
relevant standards.
Blocking these air vents may lead to severe injury, serious property damage or death.
The area in which the appliance is installed should not be used to store any other materials.
1.8
FLAME FAILURE LOCKOUT
If the LBF water heater should go to a flame failure condition, reset the unit by depressing the red lock-out
light on the control panel and a new ignition cycle will begin.
The combustion fan will pre-purge and attempt to light. Once a flame is established, the green 'Burner On'
lamp, located on the control panel, will illuminate. Should the water heater lock out again, a competent
engineer should be called to investigate the cause of the fault.
