temperature. Main burners and pilot burner should
extinguish, and blower should stop.
3. Adjust limit to setting above observed temperature.
Ignition sequence should begin.
4. Adjust thermostat to lowest setting. Adjust limit to
desired setting.
P.
Adjust gas input rate to boiler.
1. Adjust thermostat to highest setting.
2. Check manifold gas pressure. See Table 5 or rating
label located in the boiler’s vestibule compartment.
Adjust gas valve pressure regulator as necessary
(turn adjustment screw counterclockwise to
decrease manifold pressure, or clockwise to increase
manifold pressure). If pressure cannot be attained,
check gas valve inlet pressure. If less than minimum
indicated in Table 5 or boiler’s rating label, contact
gas supplier for assistance.
3. Clock gas meter for at least 30 seconds. Use Table
13 to determine gas flow rate in Cubic Feet per
Hour.
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.
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 IX: Service.
ii.
Remove gas orifices. Drill one (1) drill size
larger (drill size is stamped on orifice, or see
Section X: 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.
