and other flammable vapors and liquids.  Clean the jacket surfaces with a damp cloth 

and mild soap.  Do not use flammable cleaning materials.  Keep the vent terminal free of 

obstructions. do not pile snow against the vent terminal.

ANNUAL INSPECTION AND SERVICE

You should visually inspect the vent pipe once a year. should any corrosion or leaks 

exist, have the affected parts replaced.

Once each year a qualified service agency should conduct a detailed inspection of all flue 

product carrying areas of the boiler and vent system. Follow the service instructions in 

the “installation and operating instructions Manual” for the Laars neotherm.

boiler.  Any  part  of  the  control  system  and  any  gas  control 

which has been under water must be replaced.
