11 -  Inspect the furnace return air duct connection to 

ensure the duct is sealed to the furnace. Check for 

air leaks on supply and return ducts and seal where 

necessary.

12 -  Check the condition of the furnace cabinet insulation 

and repair if necessary.

13 -  Perform a complete combustion analysis during the 

furnace inspection to ensure proper combustion 

and operation. Consult Service Literature for proper 

combustion values.

14 -  

Verify operation of CO detectors and replace 

batteries as required.

Perform a general system test. Turn on the furnace to 

check operating functions such as the start-up and shut-

off operation.

1 -   Check the operation of the ignition system, inspect 

and clean flame sensor. Check microamps before 

and after. Check controls and safety devices (gas 

valve,  flame  sensor,  temperature  limits).  Consult 

Service Manual for proper operating range. Thermal 

Limits should be checked by restricting airflow and 

not disconnecting the indoor blower. For additional 

details, please see Service and Application Note 

H049.

2 -   Verify that system total static pressure and airflow 

settings are within specific operating parameters.

3 -   Clock gas meter to ensure that the unit is operating 

at  the  specified  firing  rate  for  each  stage  of 

operation. Check the supply pressure and the 

manifold pressure on both low fire and high fire. If 

manifold pressure adjustment is necessary, consult 

the  Service  Literature  for  unit  specific  information 

on adjusting gas pressure. Not all gas valves are 

adjustable. Verify correct temperature rise.
