Weekly Maintenance; Annual Maintenance; E As Required Maintenance - Smith 88 Installation And Operation Instructions Manual

2. Observe general boiler conditions (unusual noises,
vibrations, etc.)
3. Observe operating temperature and/or pressure on
the gauge located on the right side of the boiler.
Boiler pressure should never be higher than 5 psi
below the rating shown on the safety relief valve.
The valve rating can be found on the top of the
safety relief valve (see Figure 6.1 for location of the
safety relief valve). Boiler temperature should never
be higher than 250°F.
4. Check for water leaks in boiler and system piping.
5. Smell around the appliance area for gas. If you smell
gas, follow the "To Turn Off Gas to Appliance"
procedure listed in the Lighting/Operating
Instructions in Section 8.
C. MONTHLY MAINTENANCE (WITH BOILER
OPERATING)
1. Check boiler room floor drains for proper
functioning.
2. Check function of the safety relief valve (monthly
unless specified otherwise by manufacturer) by
performing the following test:
a. Check valve piping to determine that it is
properly installed and supported.
b. Check boiler operating temperature and pressure.
c. Lift the try lever on the safety relief valve to the
full open position and hold it for at least five
seconds or until clean water is discharged.
d. Release the try lever and allow the valve to close.
If the valve leaks, operate the lever two or three
times to clear the valve seat of foreign matter. It
may take some time to determine if the valve has
shut completely.
e. If the valve continues to leak, it must be replaced
before the boiler is returned to operation.
f. Check that operating pressure and temperature
have returned to normal.
g. Check again to confirm that valve has closed
completely and is not leaking.
3. Test low-water cut-off as described by the
manufacturer.
4. Test limit by lowering the limit set point until the
main burners shut down. When proper operation is
confirmed, return the set point to the desired setting.
5. Test function of gas safety shut-off features as
described by gas valve and ignition control
manufacturer.
6. Cycle the boiler at least once and check operation of
the vent damper
INSTALLATION AND OPERATING INSTRUCTIONS
D. ANNUAL MAINTENANCE (BEFORE
START OF HEATING SEASON)
DANGER
When servicing or replacing components, be
absolutely certain that the following conditions are
met:
Water, gas and electricity are off.
●
The boiler is at room temperature.
●
There is no pressure in the boiler.
●
1. Check flueways and burners for cleanliness and
clean if necessary. Use the following procedure if
cleaning is required:
a. Refer to the Lighting/Operating Instructions in
Section 8 "To Turn Off Gas to Appliance."
b. Turn off all electrical power to the boiler.
c. Remove burners and brush gas outlet ports
lightly using a soft bristle brush.
d. Remove the vent pipe, vent damper, top jacket
panels and flue collector.
e. Brush flueways with wire brush.
f. To the extent possible, inspect inside of vent pipe
and vent damper for obstructions in flow or vent
damper movement. Remove or replace as
necessary.
g. When replacing the flue collector, be certain that
the blanket seal between the flue collector and
top section makes a tight seal to prevent leakage
of the products of combustion.
h. Re-install the top of the jacket, vent damper and
vent pipe.
i. Connect blocked vent switch wiring harness to
blocked vent switch.
k. Re-install burners.
2. Inspect entire venting system for corrosion, support
and joint integrity. Repair as necessary.
3. Check the pilot and main burner flame. See Figure
8.1. The pilot should provide a steady flame
enveloping 3/8" to 1/2" of the flame sensor. If
required, adjust the pilot as stated in the gas valve
manufacturer's instructions. The main burner flame
inner cone should be approximately 1-1/2" high and
should have a very sharp, blue color characteristic.
E. AS REQUIRED MAINTENANCE
Test and inspect low water cut-off(s) per manufacturer's
instructions.
If the steam boiler water level is erratic and dirt &
deposits appear in the water gauge glass, skim the boiler
as described in Section 8.
