Notes for Table 1 and Table 2 1. Burner capacities listed for elevations up to 2,000 feet. For higher elevations, consult local Weil-McLain distributor/agent or sales office. 2. Light oil ratings based on No. 2 fuel oil with heating value of 140,000 Btu per gallon. 3. Gas ratings based on natural gas with heating value of 1,000 Btu per cubic foot and specific gravity of 0.60. Gas burners for other gases are available. Consult local Weil-McLain distributor/agent or sales office. 4. Boiler-burner unit to be adjusted to achieve +0.10 inches W.C. pressure at the flue collar, resulting in positive pressure in firebox as listed. 5. Minimum gas pressures listed are subject to variations due to job conditions. Gas burners for other gas pressures are available. Consult local Weil-McLain distributor/agent or sales office. 6. Tee pressures shown are for initial start-up. Final pressure should be determined after checking actual gas flow and combustion readings. 7. 120/60/1 control circuit is used for all burners. 8. Control circuit transformer is available as an option. 9. Motor relay or contactor will be furnished for all units, except 488R and 488. 10. Airflow safety switch is standard for all gas and combination gas/light oil units. 11. Burners will be completely assembled and wired (except gas train) and factory test-fired. 12. Burners listed by Underwriters Laboratories, Inc., state of Connecticut, Fire Marshal state of Massachusetts, city of New York MEA, and others. 13. Special controls can be provided to meet other code requirements not listed. Consult your local Weil-McLain distributor/agent or sales office. 14. Electric gas pilot will be furnished as standard e...
