A.CLEAN THE FLUEWAYS (See Figure 26).

1.Prior to cleaning boiler, lay a protective cloth or plastic over combustion chamber blanket to collect debris falling from flueways.

2.For access to firebox

On boilers with burner swing door and flexible fuel line(s), remove fastener securing door and swing door open. For full access to firebox, remove burner and swing door from mounting plate by pulling hairpin cotter from bottom of hinge pin and removing pin from hinge. Set burner aside. Remove swing door mounting plate, see Figure 6.

3.For cleaning from the side:

a.Lift the jacket's upper right side access panel off to expose the flue cleanout plates.

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.

4.For cleaning from the top:

a.Lift the jacket's upper right side access panel off to allow removal of the jacket top panel.

b.Remove as much smokepipe as necessary to allow removal of the jacket top panel and canopy (smokebox).

c.Remove the jacket top panel.

d.Remove the canopy, being careful not to damage the ceramic fiber gasket.

5.Using a 1¼” diameter wire or fibre bristle brush (30” handle) clean the flueways. Brush from the top and/or side using horizontal and diagonal strokes for best results. DO NOT allow brush to strike the target wall or liner in the chamber.

B.CLEAN TOP OF BOILER SECTIONS (if cleaning from the top).

Brush and vacuum the tops of the boiler sections.

C.CLEAN THE FIREBOX.

Using wire or fibre bristle brush, clean crown of boiler and inside of water legs. DO NOT allow brush to strike target wall or blanket in the combustion chamber.

D.AFTER CLEANING, remove protective cloth with debris and vacuum as necessary, but be careful not to damage blanket. Inspect target wall, combustion chamber blanket, burner mounting plate insulation and burner swing door insulation for signs of damage. If damaged, replace as needed.

E.REASSEMBLE BOILER.

CAUTION: Do not start the burner unless canopy,

smokepipe, burner mounting plate, burner swing door and all flue plates are secured in place.

1.Install the canopy taking care to align the gaskets without blocking the flueways. If gasket is damaged, replace as needed.

2.Reinstall flue plates, making sure gasket on each plate is in place and forms gas tight seal. If damaged replace as needed.

3.Reinstall jacket top panel and secure with sheet metal screws. Replace jacket upper right side access panel.

4.Reinstall smokepipe on canopy and secure to collar with sheet metal screws.

5.Install swing door mounting plate to front section with fasteners, see Figure 6.

6.Reinstall burner in reverse order of disassembly outlined in paragraph A.2 above. For details, see Figure 6.

WARNING

The boiler must be connected to an approved chimney in good condition. Serious property damage could result if the boiler is connected to a dirty or inadequate chimney. The interior of the chimney flue must be inspected and cleaned before the start of the heating season and should be inspected periodically throughout the heating season for any obstructions. A clean and unobstructed chimney flue is necessary to allow noxious fumes that could cause injury or loss of life to vent safely and will contribute toward maintaining the boiler's efficiency.
