SECTION 5 DRAFT
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 contractor, or manometers can be purchased
from the Lenan customer service department 800-753-1601.
