HANDLI NG CERAMIC FIBER
MATERI ALS
REMOVINGCOVERPLATEREFRACTORY
e Evergreen
®
cover plate refractory contains
ceramic ber
materials that have been identied as
carcinogenic, or possibly carcinogenic, to humans
.
Ceramic bers can be converted to cristobalite in
very high temperature applications.
e International Agency for Research on Cancer
(IARC) has concluded, “Crystalline silica inhaled in
the form of quartz or cristobalite from occupational
sources is carcinogenic to humans (Group 1).”:
Avoid breathing dust and contact with skin and eyes.
• Use NIOSH certied dust respirator (N95). is type of
respirator is based on the OSHA requirements for cris-
tobalite at the time this document was written. Other
types of respirators may be needed depending on the job
site conditions. Current NIOSH recommendations can
be found on the NIOSH web site at http://www.cdc.gov/
niosh/homepage.html. NIOSH approved respirators,
manufacturers, and phone numbers are also listed on
this web site.
• Wear long-sleeved, loose tting clothing, gloves, and eye
protection.
Handle carefully to minimize dust that could be caused by
abrasion.
If replacement is necessary, remove the refractory from the
boiler and place it in a plastic bag for disposal.
Wash potentially contaminated clothes separately from other
clothing. Rinse clothes washer thoroughly.

INSPECT ION
It is recommended that you obtain
a Weil-McLain
Evergreen
®
Boiler
Maintenance kit before attempting
the rst-year inspection, to ensure
all parts that may be needed are
available
. This kit includes essential
components, gaskets and seals required to
perform the annual start-up procedures.
See listing in Replacement parts. ese
parts must be on hand when you perform
the rst-year inspection in the event they
must be replaced.
Failure to replace the items above when
needed could result in severe personal
injury, death or substantial property dam-
age.
1. No later than 12months aer the boiler is in-
stalled, perform a rst-year inspection of the boiler.
is should include the following inadditionto
routineannualstart-upprocedures
.
a. Inspect the heat exchanger and clean if nec-
essary (see page111 for access and cleaning
procedures).
b. Inspect the cover plate refractory and gasket.
Replace if not in good condition.
c. Inspect the burner carefully. Clean the burner
thoroughly using a vacuum cleaner or com-
pressed air if needed.
d. Make sure there is no blockage or accumula-
tion of debris in the burner or the burner ports.
Replace the burner if necessary.
e. Check the burner for tightness.
f. Disconnect the condensate trap and drain lines.
Inspect, then ush thoroughly. Reinstall and
rell the trap per page88.
g. Check heat exchanger seals and vent seals, pro-
cedure described on page92, “Check exchanger
and vent seals”.
2. Determine any follow-up maintenance and service
needs based on the condition of the heat exchanger
and condensate lines.
a. If the heat exchanger shows substantial fouling,
or if condensate lines show accumulation of
sediment, schedule a follow-up service call to
perform the rst-year inspection again, sooner
than the normal twelve months between.
b. Heavy fouling of the exchanger or condensate
lines indicates possible combustion air contami-
nation. Inspect the air intake area carefully, and
remove possible contaminants. See page19, for
products to avoid.
You must eliminate causes of corrosion
and contamination to ensure reliable
operation of the boiler and system.
ANNU AL ST ART UP
Theboilershouldbeinspectedandstarted
annually, at the beginning of the heating season,
only by a qualied service technician. In addition,
the maintenance and care of the boiler designated
in Figure90,page93 and explained on the follow-
ing pages must be performed to assure maximum
boiler eciency and reliability. Failure to service
and maintain the boiler and system could result in
equipment failure.
TOOLS REQUI RED
Before beginning annual start-up or rst-year special inspec-
tion, obtain the tools listed on page102.
