When all these checks are O.K. you must now fire the
furnace following the operating instructions and check the
following:
Check that the circulation fan blower comes on when the
furnace reaches a temperature of 155°F.
Check that the damper door closes when the house
reaches the desired temperature.
Check that the blower fan motor shuts off when the fur-
nace temperature drops below 110°F.
When you have completed the intial start up tests and are
satisfied that the system is functioning properly you must
now fully explain the operating of the unit to your cus-
tomer. You must give your customer both the Installation
and Owner’s Operation Instructions and caution him as to
the safety practices which he must comply with.
Testing
All “Summeraire” furnaces are factory tested to ensure
reliability of welding; air streams tests have been conduct-
ed to minimize primary surface temperatures and ensure
efficient air circulation.
