GENERAL — Inspection should be conducted
A.
annually. Service as frequently as specified in
paragraphs below. While service or maintenance is
being done, electrical power to the boiler must be "off."
B.
CLEAN THE BOILER HEATING SURFACES
& FLUE at least once each year, preferably at the end
of the heating season.
1. CLEAN THE VENT SYSTEM — Vent system
should be checked annually for:
a. Obstructions.
b. Accumulations of soot.
c. Deterioration of vent pipe or vent accessories
due to condensation or other reasons.
d. Proper support — no sags, particularly in
horizontal runs.
e. Tightness of joints.
f. Remove the smoke pipe. Remove all
accumulations of soot with wire brush and
vacuum. Remove all obstructions. Replace
all deteriorated parts and support properly.
Seal all joints.
2. CLEAN THE BOILER FLUEWAYS
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. Slide baffles out through flue openings. If
necessary, use needle-nose pliers to grasp baffles.
Remove any soot buildup on the baffles.
d. Using a 1¼" diameter wire or fibre bristle brush
(36ʺ handle) clean the flueways. Start at the top
of each flueway opening and work down the pin
rows using two or three horizontal strokes per
row for best results.
3. CLEAN TOP OF BOILER SECTIONS
Remove the jacket top panel. Remove the top flue
canopy cover or outlet assembly. Use a flashlight to
inspect the upper portion of the flueways and top of
castings for soot and debris. Heavy accumulations
over 1/16" thick must be removed. Remove the
canopy being careful not to damage the cerafelt
strips. Brush and vacuum the upper flueways and
tops of castings.
4. CLEAN THE FIREBOX
a. Disconnect fuel line(s) and remove burner and
burner mounting plate.
b. Using wire or fibre bristle brush clean crown of
boiler and inside of water legs.
c. Inspect target wall (V903A only) for damage or
deterioration. If target wall is damaged, replace.
5. REASSEMBLE BOILER
Do not start the burner unless canopy, smokepipe,
burner mounting plate and all flue plates are secured
in place.
Ne démarrez pas le brûleur tant que l'auvent, le tuyau
de fumée, la plaque de montage du brûleur et toutes les
plaques de cheminée ne sont pas fixés en place.
a. If removed, install the canopy taking care to
align the cerafelt strips. If strips are damaged
replace as needed.
b. Reinstall burner mounting plate to front section
making sure 3/16" diameter rope gasket is
in place and forms gas tight seal. If gasket is
damaged, replace.
c. Bolt burner to burner mounting plate. Inspect
gasket to assure adequate seal. Replace if
damaged. Connect oil line(s) and/or gas line(s).
d. Reinstall flue plates making sure gasket on each
plate is in place and forms gas tight seal. If
damaged, all edges of the cleanout plates should
be sealed with silastic sealant when reinstalled
until insulation can be replaced.
e. If removed, reinstall jacket top.
f. Reinstall left side panels.
g. Reinstall smokepipe.
C.
MAINTENANCE OF LOW WATER CUTOFF
DEVICES.
Probe and float type low water cutoff devices require
annual inspection and maintenance.
Les dispositifs de coupure de bas niveau d'eau de
type sonde et flotteur nécessitent une inspection et un
entretien annuels.
1. PROBE TYPE LOW WATER CUTOFF
Although these devices are solid state in their
operation, the probe is exposed to possible
contamination in the boiler water and subject to
fouling.
It is important to physically remove the probe from
the boiler tapping annually and inspect that probe
for accumulation of scale or sediment.
Follow these steps to inspect, clean and/or replace
the probe:
a. Turn off electric service to the boiler.
b. Drain boiler water to a level below the tapping
for the probe.
