4.Place only the Burners with pilots mounted in the locations given in Table 2.2. Install the Burners by slipping the opening on the front of the burner over the orifice adapter and slipping the pin on the end of the burner into the hole in the Burner Support Channel directly opposite the orifice.

5.Cut and fit the 1/4" aluminum tubing provided from the pilot gas shut-off device(s) to the pilot burners.

6.Do not install the remaining burners until the Boiler Sections are installed.
