HANDLING CERAMIC FIBER
MATERIALS
REMOVAL OF COMBUSTION
CHAMBER LINING
The combustion chamber lining in this
product contains ceramic fiber mate-
rial. 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 respira-
tors may be needed depending on the job site
conditions. Current NIOSH recommenda-
tions 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 fitting clothing, •
gloves, and eye protection.
Apply enough water to the combustion chamber
lining or base insulation to prevent airborne dust.
Remove combustion chamber lining or base insula-
tion from the boiler and place it in a plastic bag for
disposal.
Wash potentially contaminated clothes separately
from other clothing. Rinse clothes washer thor-
oughly.
NIOSH stated First Aid
Eye: Irrigate immediately
Breathing: Fresh air.
FIRST-YEAR SPECIAL INSPECTION
. This kit includes a heat exchanger
cover plate gasket, burner gasket (80 and
105 only), new ignitor, and ignitor gasket.
See listing in Replacement parts section of
this manual. These parts must be on hand
when you perform the first-year inspec-
tion 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. after the boiler is in-
stalled, perform a first-year inspection of the boiler.
This must include the following
.
Remove the heat exchanger cover plate. Inspect a.
the heat exchanger and clean if necessary. See
instructions for removing and replacing the heat
exchanger cover plate, and for cleaning the heat
exchanger, in the Maintenance section of this
manual. Replace the cover plate gasket if not in
good condition.
Inspect the burner gasket (80 and 105), and b.
replace if necessary. Make sure the burner is
clean, and that is is fastened tightly to the cover
plate.
Disconnect condensate trap and drain lines. c.
Inspect, then ush thoroughly.
Determine follow-up maintenance and service 2.
needs based on the condition of the heat exchanger
and condensate lines.
If the heat exchanger shows substantial fouling, a.
or if condensate lines show accumulation of
sediment, schedule a follow-up service call to
perform the first-year inspection again, sooner
than the normal twelve months between.
Heavy fouling of the exchanger or condensate b.
lines indicates possible combustion air contami-
nation. Inspect the air intake area carefully, and
remove possible contaminants. See “ Corrosive
contaminants and sources,” Figure 30, page 30,
for products to avoid.
You must eliminate causes of corrosion
and contamination to ensure reliable
operation of the boiler and system.
