J.
Check thermostat or operating control operation
.
Raise and lower temperature setting to start and stop
boiler operation.
K.
Check ignition system shut-off.
1. Standing Pilot (24V): Disconnect thermocouple
lead at Gas Valve. Gas Valve must close and pilot
and main burners extinguish. If not, replace the gas
valve.
2. Honeywell EI: Disconnect ignitor/sensor cable from
ignition module. Gas valve must close and pilot and
main burners extinguish. If not, measure voltage
across gas valve terminals “TH” and “TR”.
a. If voltage is not present, replace gas valve.
b. If voltage is present, replace ignition module.
3. EP: Refer to instructions supplied with the
Honeywell RM7890 Burner Control.
L.
Check Limit(s).
NOTE: If using Model 805, see
Installation and Operating manual for Hydrostat 3200,
packed in envelope taped to top of boiler for packaged
boilers and in parts and control carton for KD boilers
for maintenance.
1. Adjust thermostat to highest setting.
2. Observe temperature gauge. When temperature
exceeds limit set point main burners should
extinguish.
3. Adjust limit to setting above observed reading. Main
burners should reignite.
4. Adjust thermostat to lowest setting. Adjust limit to
desired setting.
M.
Adjust gas input rate to boiler
. Natural Gas.
1. Adjust thermostat to highest setting.
2. Check manifold gas pressure. Manifold pressure
is listed on rating label. Adjust gas valve pressure
regulator as necessary (turn adjustment screw
counterclockwise to decrease manifold pressure, or
clockwise to increase manifold pressure). If pressure
can not be attained, check gas valve inlet pressure.
If less than minimum gas supply pressure listed on
rating label, contact gas supplier for assistance.
3. Clock gas meter for at least 30 seconds. Use Table
12 to determine gas flow rate in Cubic Feet per
Hour.
4. Determine Input Rate. Multiply gas flow rate by gas
heating value.
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.
5. Compare measured input rate to input rate stated on
rating label.

Table 12: Input Rate
a. Boiler must not be overfired. Reduce input rate
by decreasing manifold pressure. Do not reduce
more than 0.3 inch w.c. If boiler is still overfired,
contact your Burnham distributor or Regional
Office for replacement Gas Orifices.
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
Key No. 4E).
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.
