APPENDIX G – CHECkING DRAFT AND COMBUSTION
CHECK DRAFT (GAS BOILERS WITH DRAFT HOODS)
1.
  Insofar as is practical, close all doors and 
windows in the building.
2.
  Turn on all appliances not connected to the 
same venting system as the boiler being 
checked.
3.
  Turn on all exhaust fans (such as range 
hoods and bathroom exhausts) to their 
maximum speed.  Do not turn on any 
summer exhaust fans.
4.
  Close all fireplace dampers.
5.
  Operate the appliance being checked. 
Follow lighting instructions.
CHECK DRAFT (OIL BOILERS)
1.
  Use a manometer precise to 0.01” water 
column.
2.
  Fire the boiler until the chimney/vent reaches 
normal operating temperature.
3.
  Locate the pressure sensing tapping on the 
boiler.
4.
  While the boiler is still firing, use the 
manometer to measure the draft at the 
pressure tapping.
5.
  Confirm that the draft measurement matches 
the required draft specified for the boiler.
6.
  If the required draft is not present, make any 
necessary adjustments and check again.
CHECK COMBUSTION
1.
  Use a flue gas analyzer that accurately 
measures CO
2
, O
2
, CO, and flue gas 
temperature.
2.
  For oil boilers, also use a smoke tester with 
smoke test paper.
3.
  Operate the boiler at its rated (high fire) 
input.
4.
  With the analyzer, check the CO
2
 (or O
2
), 
CO and temperature of the flue gases 
exiting the boiler.
5.
  For two-stage or modulating boilers, also 
check the CO
2
 (or O
2
), CO and temperature 
of the flue gases at low fire.
6.
  Confirm that the measured CO
2
 (or O
2
matches the required CO
2
 (or O
2
) specified 
for the boiler.
7.
  For oil boilers, also take a smoke 
measurement of the flue gases.  Smoke 
should not exceed #1.
  If CO
2
, O
2
, or CO fall outside of the 
             range specified for the boiler, review the 
installation and startup instructions and make 
any necessary adjustments to the boiler or 
associated venting or piping systems.
 
          
i        
  Note the gross flue gas temperature for   
           future reference.  Significant changes in 
           flue gas temperature can indicate changes 
in the boiler’s operating efficiency.
6.
  After 5 minutes of main burner operation, 
test for spillage at the draft hood relief 
opening, using a lighted match, candle, 
cigarette, etc.
7.
  Repeat this test for each appliance 
connected to the common venting system.
8.
  If any appliance does not vent properly, per 
the above test, make corrections, so that the 
installation conforms to the National Fuel 
Gas Code
NFPA 54/ANSI Z223.1, and/or 
Installation CodesCAN/CSA B149.1.
9. 
Return doors, windows, exhaust fans, 
fireplace dampers, and any other gas-
burning appliance to their previous condition 
of use.
