Notes for Table 1, Table 2 and Table 3 (continued)

be driven to both low fire and high fire positions, prevent start up if pre-ignition interlocks are open and has low fire start proven circuit. In the event pre-ignition interlock circuit or running interlock circuit does not “prove”, system will lock out on safety. Ultra violet sensitive electronic flame detector is standard.

17.Other flame safeguards available upon request.

18.Control circuit transformer is available as an option.

19.Airflow safety switch is standard for all gas and combination gas/light oil units.

20.Burners will be completely assembled and wired (except gas train) and factory test-fired.

21.Burners listed by Underwriters Laboratories, Inc., state of Connecticut, Fire Marshal state of Massachusetts, city of New York MEA, and others.

22.Special controls can be provided to meet other code requirements not listed. Consult your local Weil-McLain distributor/agent or sales office.

23.Electric gas pilot will be furnished as standard equipment on all combina- tion gas/light oil units.

24.Direct spark ignition is available as an option for combination gas/light oil units. Consult your local Weil-McLain distributor/agent or sales office.
