The Lanair heater should have a (negative) -.02 draft reading when cold, and a (negative) -.06
when hot. Check the heater when it is running after 45 minutes. If the reading is not what it
should be, adjust the barometric damper according to the instructions provided with the
damper. The draft reading should be taken with a manometer. Consult your heating contrac-
tor, or a manometer can be purchased from the Lanair Customer Service Department .
