2.2 — Draft Conditions
Automatic over-fire draft control or barometric draft regulators are not usually required except where the system
has a tall chimney. The exact height of a chimney requiring draft control is indeterminate, but draft regulation is
seldom needed for chimneys less than 50 feet high, especially with Scotch Marine or sealed firebox boilers.
