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-tightenscrews.

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.
