2. Spray inside surfaces with light lubricating or
crankcase oil using gun with extended stem so as to
reach all corners.
3. With steam boilers, at end of season add sufficient
water to fill boiler to top of water column and leave
it that way until fall when water should be drained
again to proper level. If, at this time, boiler water
is dirty, drain water, flush out boiler, and refill with
clean water to prescribed water level.
4. Always keep the manual fuel supply valve shut off
if the burner is shut down for an extended period of
time.
VII: MAINTENANCE AND SERVICE INSTRUCTIONS (continued)
VIII: BOILER CLEANING
WARNING
All boiler cleaning must be completed with burner service switch turned off.
A.
CLEAN THE FLUEWAYS (See Figure 31).
1. Disconnect oil line(s) and remove burner and burner
mounting plate. See Figures 1A thru 1D.
2. Lay protective cloth or plastic over combustion
chamber blanket.
3. Remove the smokepipe as necessary to gain access
to the boiler canopy.
4. Remove the jacket top panels.
5. Remove the canopy being careful not to damage the
cerafelt gasket.
6. Using a 1¼” diameter wire or fibre bristle brush
(30” handle) clean the flueways. Brush from the top
using 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.
1. Brush and vacuum the tops of the boiler sections.
C.
CLEAN THE FIREBOX.
1. 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 and burner mounting plate insulation
for signs of damage. If damaged, replace as needed.
E.
REASSEMBLE BOILER.
CAUTION: DO NOT
start the burner unless canopy,
smokepipe and burner swing door 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. Close and secure burner swing door to front section
with fasteners.
3. Reconnect oil line(s).
4. Reinstall Top Panels and secure with sheet metal
screws.
5. Reinstall smokepipe on canopy and secure to collar
with sheet metal screws.
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.
5. To recondition the heating system in the fall season
after a prolonged shut down, follow the instructions
outlined in Section V, Paragraphs A through K.
WARNING
This boiler contains controls which may cause the
boiler to shut down and not restart without service.
If damage due to frozen pipes is a possibility, the
heating system should not be left unattended
in cold weather; or appropriate safeguards and
alarms should be installed on the heating system
to prevent damage if the boiler is inoperative.
