Fiberglass wool and ceramic fiber materials:
• POSSIBLE CANCER HAZARD
BY INHALATION
• CAN CAUSE RESPIRATORY,
SKIN AND EYE IRRITATION
This product contains fiberglass wool and ceramic
fiber materials. Airborne fibers from these materials
have been listed by the State of California as a
possible cause of cancer through inhalation. Apply
special care when handling ceramic fiber (chamber
lining, base insulation) materials. Ceramic fibers can
be converted to chrystobalites, a substance listed as a
probable cause of cancer.
Suppliers of fiberglass wool products recommend
the following precautions be taken when handling
these materials:
Precautionary measures:
• Avoid breathing fiberglass dust and contact
with skin and eyes.
• Use NIOSH approved dust/mist respirator.
• Wear long-sleeved, loose fitting clothing, gloves
and eye protection.
• Wash work clothes separately from other
clothing. Rinse washer thoroughly.
• Operations such as sawing, blowing, tearout
and spraying may generate airborne fiber
concentration requiring additional protection.
First aid measures:
• Eye contact — Flush eyes with water to remove
dust. If symptoms persist, seek medical attention.
• Skin contact — Wash affected areas gently
with soap and warm water after handling.
Place boiler:
1. A-SGO-3 through 6W — position on site.
Smaller-sized boilers may be top
heavy. Use caution when
handling to avoid minor personal injury or
property damage.
a. Boiler is shipped for back flue outlet.
To change to top flue outlet (see FIGURE 2):
1) Loosen two screws holding flue cap strap
to collector hood. Remove strap and flue
cap from opening. Re-tighten screws.
2) Check rope placement inside flue cap.
(Read under Step #3 on
page 7.)
3) Loosen two screws on back flue outlet. Set
flue cap on outlet. Install strap by
engaging slots in screws. Tighten screws.
Make sure cap is securely installed.
2. A-SGO-7, 8 & 9W— split the assembled block
for easier handling (see FIGURE 2):
a. Open burner mounting door and,
using utility knife, slit floor insulation at
joint to be separated.
b. Remove 5½" draw rod and the longest draw
rod from each side. Pull block apart. Save
draw rods, nuts, washers and sealing rings
for reassembly.
c. Move divided block to location.
d. Clean port openings with clean rag.
Do not use petroleum-based
compounds to clean
openings. Damage to system components
can result, causing property damage.
e. Place rings in port openings. If ring slips out
of groove, stretch ring gently for several
seconds, then place in groove.
f. Position sections so aligning lugs fit into
sockets of next section. Make sure sealing
rope is in good condition and in position.
g. Oil threads on draw rods. Install washer
and nut on end to be tightened. Use nut
only on other end.
h. With wrench at washer/nut end,
uniformly tighten nuts starting with 5½"
rod at large port, 5½" rod at small port,
bottom long rod and finally top long rod.
i. Torque on both 5½" rods and bottom
long rod should be 50-60 ft. lbs; long
top rod should be 20-25 ft. lbs. Do not
back-off nuts.
j. Metal-to-metal contact should be
made around port openings. If gap
does exist, it should be less than .020".
Check with feeler gauge.
k. If gap around port openings exceeds .020",
check for dirt on port openings, sockets or
misaligned lugs. If corrections are made
and gap still exists, contact your
Weil-McLain distributor or sales office
before continuing installation.
