Properly installed and located service switch; and6. Properly installed and located low water cut-off.8.5.3Combustion Efficiency Test RequiredWhen performing an installation, a combustion efficiency test must be conducted, and a copy of the test results must be posted on-site.
8.5.4Water and Condensate Connections to Boilers and Water Heaters 8.5.4.1Hot and Cold Water PipingA master or journeyman oil burner technician may connect hot and cold water piping from a boiler or oil fired water heater to existing piping only in the same room where the installation is taking place.
