9.
Check the operation of the burner; start and stop it several times with the thermostat
or operating control.
10. With the burner running, check the operation of all limit and associated controls.
11. Perform the following final adjustments for combustion and flue gas temperature. Take the
flue gas samples and temperature immediately upstream of the draft control.
A.
The flue gas temperature should be above 325°F but not exceeding 550°F.
Excessive flue gas temperatures will result in low efficiencies. Low flue gas
temperature may cause excessive condensation. Reset gas input, if necessary, to
adjust stack temperature.
B.
Make the final setting of the combustion air shutter by checking the flue gases
with an
ORSAT or
similar combustion testing instrument. The carbon monoxide
content should conform to local codes, or in their absence, to the level specified
in the United States or Canadian Standard referenced on the front cover of this
manual; and the carbon dioxide content should be approximately 9.5% for
NATURAL or 12% for propane , or within the limits prescribed by local codes.
12. Check the draft control to make sure there is no spillage of flue products into the room.
13.
FILL OUT THE INSTALLATION ADJUSTMENT DATA TAG
and affix to the burner or
gas utilization equipment.
NOTE:
For subsequent normal starting and shut off procedure, refer to
CONSUMER
INSTRUCTIONS
, located in part 3 of this manual,
or to the instruction plate mounted
