54 2. CLEAN THE BOILER FLUEW A YS a. Remove the jacket left side panels. b. Loosen nuts securing the flue cleanout plates and remove the plates. The insulation should be removed with the plates taking care not to damage the insulation. c. Using a 1¼” diameter wire or fibre bristle brush (36” handle) clean the flueways.
55 b. Using wire or fibre bristle brush clean crown of boiler and inside of water legs. c. Inspect target wall (903A only) for damage or deterioration.
56 2. FLOA T TYPE LOW W A TER CUT OFF During the heating season, if an external low water cutoff is on the boiler , the blow off valve should be opened once a month (use greater frequency where conditions warrant) to flush out the sediment chamber so the device will be free to function properly .
