1. Radiant tubing between burners, and 20-50' (6-15 m) downstream of the last burner is normally hot rolled steel or heat-treated aluminized steel. All tailpipe tubing must be por- celain coated steel or heat-treated aluminized steel.
2.Damper couplings are required when layout has unequal branches. Unequal branches are achieved by unequal geometry, burner quantity or burner firing rates.
3.Plain couplings are used to connect combustion chambers to radiant tubing and radiant tubing to tailpipe tubing. All tailpipe couplings must be lined.
