6. Once the configuration for the appropriate heating
system is complete, press the NEXT key until the
LCD displays the “Start test in __Sec.” screen. Press
the + key to designate the delay before the test is to
start. This service test will begin after the TEST
START key is pressed and the delay designated in
this step has elapsed. Press the ENTER key to
confirm this choice.

7. Press the TEST START key to start the test.
Remember that the delay designated in step 6 must
elapse before the fan will begin to operate.
8. Once the system has started, verify that the electric
heat or the hydronic heat system is operating
properly by using appropriate service technics; i.e.
amperage readings, delta tees, etc.
9. Press the STOP key at the Human Interface Module
in the unit control panel to stop the system
operation.
Gas Furnace Start-Up
(Constant Volume and Variable Air Volume
Systems)
It is important to establish and maintain the
appropriate air/fuel mixture to assure that the gas
furnace operates safely and efficiently.
Since the proper manifold gas pressure for a particular
installation will vary due to the specific BTU content of
the local gas supply, adjust the burner based on carbon
dioxide and oxygen levels.
The volume of air supplied by the combustion blower
determines the amount of oxygen available for
combustion, while the manifold gas pressure
establishes fuel input. By measuring the percentage of
carbon dioxide produced as a by-product of
combustion, the operator can estimate the amount of
oxygen used and modify the air volume or the gas
pressure to obtain the proper air/fuel ratio.
Confirming the correct air/fuel mixture for a furnace
results in rated burner output, limited production of
carbon monoxide, and a steady flame that minimizes
nuisance shutdowns.
