HANDLING CERAMIC FIBER
MATERIALS
REMOVING BURNER GASKET or
COVER PLATE INSULATION
The EVG cover plate refractory contain
ceramic fi ber materials that have been
identifi ed as carcinogenic, or possibly
carcinogenic, to humans.
Ceramic fibers can be converted to
cristobalite in very high temperature
applications.
The 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 certified dust respirator (N95).
This type of respirator is based on the OSHA
requirements for cristobalite 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 fi 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.
NIOSH stated First Aid
■
Eye: Irrigate immediately
■
Breathing: Fresh air.
FIRST-YEAR SPECIAL INSPECTION
It is recommended that you obtain a
Weil-McLain Boiler Maintenance kit before
attempting the fi rst-year inspection, to ensure
all parts that may be needed are available
. This
kit includes a heat exchanger cover plate gasket,
burner gasket, new ignitor, and ignitor gasket. See
listing in Replacement parts section of this manual.
These parts must be on hand when you perform
the fi 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 damage.
1. No later than 12 months
after the boiler is installed,
perform a fi rst-year inspection of the boiler. This should
include the following
in addition to routine annual start-
up procedures .
a. Inspect the heat exchanger and clean if necessary (see
page 117 , EVG 70 or 110, or page 123 , EVG 155, for access
and cleaning procedures).
b. Inspect the cover plate refractory and gasket. Replace if
not in good condition.
c. Inspect the burner and inspect carefully. Clean the burner
thoroughly using a vacuum cleaner and compressed air
if needed.
d. Make sure there is no blockage or accumulation of debris
in the burner or the burner ports. Replace the burner if
necessary.
e. EVG 70 or 110: Check the burner for tightness. Remove
the cover plate refractory and tighten the burner
mounting screws if needed, following the instructions
on page 117 .
f. EVG 155: Check burner access cover for tightness.
g. Make sure to follow the inspection procedure given in
“Chec k exchanger and vent seals,” page 98 .
h. Disconnect the condensate trap and drain lines. Inspect,
then fl ush thoroughly. Reinstall and refi ll the trap per
page 93 .
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 fi rst-year
inspection again, sooner than the normal twelve months
between.
b. Heavy fouling of the exchanger or condensate lines
indicates possible combustion air contamination.
Inspect the air intake area carefully, and remove possible
contaminants. See page 22 , for products to avoid.
You must eliminate causes of corrosion and
contamination to ensure reliable operation of the
boiler and system.
