WARNING
Failure to properly adjust gas input rate will result
in over firing or under firing of the appliance.
Improper and unsafe boiler operation may result.
4. Determine Input Rate. Multiply gas flow rate by gas
heating value.
5. Compare measured input rate to input rate stated on
rating plate.
a. Boiler must not be over fired. Reduce input rate
by decreasing manifold pressure. Do not reduce
more than 0.3 inch w.c. If boiler is still overfired,
contact your U.S. Boiler distributor or Regional
Office for replacement Gas Orifice.
VIII. SYSTEM START-UP (continued)
b. Increase input rate if less than 98% of rating
plate input. Increase manifold gas pressure no
more than 0.3 inch w.c. If measured input rate is
still less than 98% of rated input:
i. Remove Main Burners per procedure in
Section XI: Service.
ii. Remove gas orifices. Drill one (1) drill size
larger (drill size is stamped on orifice, or see
Section XII: Repair Parts).
iii. Reinstall gas orifices and main burners.
Measure input rate.
6. Recheck Main Burner Flame.
7. Return other gas-fired appliances to previous
conditions of use.
8. Measure and record air free carbon monoxide
(COAF) must be less than 50 ppm.
