Check Pilot Burner Flame.
1. Continuous Ignition (Standing Pilot), Models 30
through 70. See Figure 18. Pilot burner produces a
single flame. The flame should be steady, medium
hard blue enveloping 3/8 to 1/2 inch of
thermocouple.
2. Continuous Ignition (Standing Pilot), Model 80. See
Figure 19. Pilot burner produces three (3) flames.
The center flame should be steady, medium hard
blue enveloping 3/8 to 1/2 inch of thermocouple.
3. Intermittent Ignition (EI). See Figure 20. The pilot
burner should be lit only if thermostat is calling for
heat. The pilot burner produces three (3) flames.
The center flame should be steady, medium hard
blue enveloping 3/8 to 1/2 inch of thermocouple.
G.
Check Ignition System Shutoff.
Gas valve should close
and pilot and main burners should extinguish.
1. Continuous Ignition (standing pilot). Disconnect
thermocouple at gas valve.
2. Intermittent Ignition (EI). Disconnect sensor cable
from Terminal 4 SENSE on Ignition Module.
H.
Check Vent Damper Operation.
Vent Damper must be
in open position when main burners are ignited.
I.
Check Limit.
1. Adjust thermostat to highest setting.
2. Observe temperature gauge. When temperature is
indicated, adjust limit to setting below observed
temperature. Main burners should extinguish.
3. Adjust limit to setting above observed temperature.
Ignition sequence should begin.
4. Adjust thermostat to lowest setting. Adjust limit to
desired setting.
J.
Check Thermostat Operation
. Raise and lower
temperature setting to start and stop boiler operation.
Adjust thermostat to normal setting.
K.
Combustion Chamber Burn-Off
1. The mineral wool combustion chamber panels
contain a cornstarch based binder that must be
burned out at installation to prevent odors during
subsequent boiler operation.
2. Ventilate the boiler room, set the high limit to its
maximum setting, set the thermostat to call for heat.
Allow the boiler to fire for at least an hour or until
the odor from the cornstarch has dissipated.
3. Return the high limit and thermostat to their desired
settings.
L.
Review User's Information Manual
and system
operation with owner or operator.
M.
Post instructions
near boiler for reference by owner and
service personnel.
