10. Once the alignment between the manifold and the burner is complete, secure the manifold to the burner panel using four (4) screws.
11. Place the manifold bracket onto the air box and manifold inlet pipe and secure with two (2) hex head screws.
12. Connect the brown and yellow wires to the gas valve.
13. Place the manifold gasket over the manifold inlet pipe and slide it between the air box cutout and the manifold bracket cutout.
14. Reconnect the gas supply line to the gas valve. Turn on the main gas supply and check the connections for leaks.
CAUTIONSome leak test solutions (including soap and water) may cause corrosion or stress cracking. Rinse the piping with water after testing.
WARNINGNever test for gas leaks with an open flame. Always use a test leak solution or liquid soap solution to check for gas leaks at connections.
15. Confirm the wiring is correct. See Figure 8.16. Follow steps 1 through 4 of Section F to complete
