Now that the weather is warmer and "any" chance of snow is small to non existent, it is a good time to overhaul and maintain your monitor heaters. Unplug the unit, shut off and disconnect the fuel line, remove the exhaust tube nut and gasket, pull the unit out of the wall and get it to a workbench. Remove the front panel and vacuum the heat exchanger fins. Open up the fuel sump and clean any sludge gunk off the bottom of the sump. Clean the sump filter. Take the fan guard off remove the fan blade and wash with soap and water. The combustion blower uses ball bearings but there may not be a fiber dust cover on them. Lubricate these with a light machine oil. The fan, same light machine oil. Use a solvent to clean the flame rod. Take the cover off the combustion pot and look at the burner mat. If its all curled up replace it. Look at the burner head if its really distorted replace it. Look at the air holes. Use a small wire brush to clean these. Use new gaskets when replacing the covers.
