established. If more than 2 tries for ignition are needed,
it will be necessary to press the reset button to restart
the boiler. Once a flame has been established for the
first time, subsequent calls for burner operation should
result in a flame on the first try.
I. Check Burner Flame
Inspect the flame visible through the window. On high
fire the flame should be stable and mostly blue (Figure
33). No yellow tipping should be present; however,
intermittent flecks of yellow and orange in the flame are
normal.
J. Check Gas Inlet Pressure
Check the inlet pressure and adjust if necessary. Verify
that the inlet pressure is between the upper and lower
limits shown on the rating plate with all gas appliances
on and off.
WARNING
Asphyxiation Hazard. The outlet pressure for
the gas valve has been factory set and requires
no field adjustment. This setting is satisfactory
for both natural gas and propane. Attempting to
adjust the outlet pressure may result in damage
to the gas valve and cause property damage,
personal injury or loss of life.
K. For LP Gas, perform procedure
as described
in Paragraph Q “Field Conversion From Natural Gas to
LP Gas”.
L. Perform Combustion Test
WARNING
Asphyxiation Hazard. Each Phantom
Series boiler is tested at the factory and
adjustments to the air fuel mixture are
normally not necessary. Improper gas
valve or mixture adjustments could result in
property damage, personal injury or loss of
life.
Any gas valve adjustments (throttle and/
or offset) specified herein and subsequent
combustion data (%O
2
, %CO
2
, CO ppm)
collection must be performed using a
calibrated combustion analyzer.
Failure to use combustion analyzer could
result in property damage, personal injury
or loss of life.
1. Remove flue temperature sensor
from vent
connector (see Figure 9) and insert combustion
analyzer probe through flue temperature sensor
cap opening. If required, also remove the flue
temperature sensor silicon cap and insert the
analyzer probe directly into flue sensor port.
Reinstall the sensor and the cap upon combustion
testing completion.
2. Verify O
2
(or CO
2
) and CO are within limits
specified in Table 22 (natural gas) or Table 23 (LP
gas) at both high and low fire as described in the
following steps.
IX. System Start-up
(continued)
Status
Control Action
Initiate
Power-up
Standby Delay
This state is entered when a delay is
needed before allowing the burner control
to be available and for sensor errors.
Standby
Boiler is not firing. There is no call for
heat or there is a call for heat and the
temperature is greater than setpoint.
Safe Startup
Tests flame circuit then checks for flame
signal.
Drive Purge
Driving blower to purge rate setting and
waiting for the proper fan feedback.
Prepurge
Purges the combustion chamber for the
10 second purge time.
Drive Light-off Driving blower to light-off rate setting and
waiting for the proper fan feedback.
Pre-ignition
Test
Tests the safety relay and verifies that
downstream contacts are off.
Pre-ignition
Energizes the igniter and checks for
flame.
Direct
Ignition
Opens main fuel valve and attempts
to ignite the main fuel directly from the
ignition source.
Running
Normal boiler operation. Modulation rate
depends on temperature and setpoint
selections and modulating control action.
Postpurge
Purges the combustion chamber for the
30 second purge time.
Lockout
Prevents system from running due to a
detected problem and records fault in
Lockout History.
