CAUTION / ATTENTION
Electrical Shock Hazard. Label all wires prior to
disconnection when servicing controls. Wiring
errors can cause improper and dangerous
operation. Verify proper operation after
servicing.
Au moment de l´entretien des commandes,
étiquetez tous les fils avant de les débrancher.
Les erreurs de câblage peuvent nuire au bon
fonctionnement et être dangereuses.
S´assurer que l´appareil fonctionne
adéquatement une fois k´entretien terminé.
9.
Inspect the condensate trap to verify it is open and free
from debris. Inspect condensate line integrity between
boiler and condensate neutralizer (if used), condensate
neutralizer and the drain. Clean/repair if needed.
If the condensate neutralizer is used, check pH before
and after the neutralizer to determine neutralizing
effectiveness. Replace limestone chips and clean out
the neutralizer if needed.
10.
Inspect the flue temperature sensor cap to verify that
it is free from leakage and deterioration. Replace if
needed.
11.
Inspect vent connections and vent connector to heat
exchanger seals to verify that they are free from
leakage and deterioration. Repair as needed. Follow all
instructions in Section IV “Venting” when reassembling
vent system.
12.
Check for vent and air intake terminal for obstructions
and clean as necessary. Check rodent screens in vent
and air intake terminations to verify they are clean and
free of debris.
13.
Reinstall the burner/blower/gas valve assembly and
secure with M6X1 hex flange nuts.
14.
Reconnect any wiring which has been disconnected
.
15.
Verify that the system pH is between 7.5 and 9.5.
16.
Inspect the heating system and correct any other
deficiencies prior to restarting the boiler.
17.
Follow Section IX “System Start-up” before leaving
installation.
18.
Perform the combustion test outlined in Section IX
“System Start-up”.
D. Recommended Heating System Water
Treatment Products:
1. System Cleaning and Conditioning:
a. The following heating system water treatment
products are recommended for an initial existing
heating system sludge removal, initial boiler
cleaning from copper dust, flux residue and any
boiler debris and for preventive treatment as
corrosion/scale inhibitors:
i.
Fernox™ Restorer (universal cleaner, sludge
remover, scale remover, flux residue/debris
remover, corrosion inhibitor)
ii.
Fernox™ Protector (Alphi 11, CH#, Copal)
(sludge remover, corrosion inhibitor)
Follow manufacturer application procedure
for proper heating system/boiler cleaning and
preventive treatment.
Above referenced products are available
from Cookson Electronics Company, 4100
Sixth Avenue, Altoona, PA 16602, Tel: (814)
946-1611 and/or selected HVAC distributors.
Contact Thermal Solutions for specific details.
4.
Remove the igniter assembly and flame sensor and
inspect them for oxide deposits. Clean the oxide deposits
from the igniter electrodes and flame sensor rod with
steel wool. Do not use sandpaper for the cleaning.
Inspect the ceramic insulators for cracks and replace
the igniter assembly and/or flame sensor if necessary.
Check the igniter electrode spacing gap. Refer to Figure
41 “Igniter Electrode Gap” for details.
XI. Service and Maintenance

5.
To gain access to boiler burner and combustion chamber,
first disconnect and remove gas inlet piping from gas
valve. Then, remove six M6X1 hex flange nuts and
take out the burner/blower/gas valve assembly from
the boiler.
6.
Inspect the assembly for lint and dust presence. If
significant lint and dust accumulations are found,
disassemble the blower/gas valve assembly to expose
the swirl plate and blower inlet. For parts identification,
refer to Section XIII “Repair Parts”. Vacuum these parts
as required, being careful not to damage the vanes on
the swirl plate.
7.
Vacuum any dust or lint from the burner if present. If
the burner shows any visual deterioration or corrosion
signs, replace it immediately. Inspect the burner gasket
and replace if necessary.
8.
Inspect the heat exchanger combustion chamber, clean
and vacuum any debris found on the surfaces. If
required, brush the coils of the heat exchanger using a
non-abrasive, non-metal bristle brush. Any cleaning of
the combustion chamber with acid or alkali products is
prohibited. Do not use any cleaning agents or solvents. If
insulation disc has signs of damage, it must be replaced.
