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 tail-
pipe couplings must be lined.
