INSPECT EXISTING CHIMNEY before
installing boiler. Failure to clean or replace
perforated pipe or tile lining will cause severe injury
or death.
Vent installation shall be in accordance with
"Venting of Equipment," of the National Fuel Gas
Code, ANSI Z223.1/NFPA 54, or "Venting Systems
and Air Supply for Appliances," of the Natural Gas
and Propane Installation Code, CAN/CSA B149.1,
or applicable provisions of the local building codes.
Observe all general venting guidelines provided in
Appendix B—Venting. Additionally:
1. Install any of the following for this Series 3
