Gp burner, Warning – I.C.E. GIDM-325 User Manual
GP TYPE C FORCED DRAFT BURNER C-6.2 TO C-12.9
INITIAL START UP
1. Make sure burner power switch is off and manual main and pilot valves are closed.
2. Make proper settings on limit controls.
3. Have on hand CO and CO
tester, stock thermometer, 0” to 30”W.C. gas pressure gauge, u- tube manometer and
D.C. volt meter.
4. Turn on burner power switch momentarily to check blower rotation.
5. Check gas tightness of main and pilot safety shut off valves (if used) by connecting a pressure gauge to the
pressure tap located between the safety shut-off valve and the test firing valve. When the test firing valves are
closed and the manual shut-off valves are opened, no pressure rise should show on the pressure gauge.
6. The air damper has been factory set approximately during test firing if need to adjust see linkage set up sheet
provided with unit. Turn on the burner switch, while the main and pilot gas firing valves are closed. After the
prepurge the ignition transformer and solenoid valves will be energized. Observe the ignition spark for proper
location and firmness. After the trial for ignition time, the ignition transformer and solenoid valve are
deenergized and the burner will lock out.
7. Open the pilot test firing valve and turn on the burner switch, while the manual main shut-off valve stays closed.
After the prepurge, the ignition transformer and the pilot solenoid valve are energized. Observe the pilot flame
and if necessary, adjust the pilot pressure regulator to obtain a stable flame with the highest steady flame signal.
For flame signal readings, see attached flame safeguard manual. With the main manual shut-off valve still closed,
the flame safeguard will lock out after approximately 10 seconds, only with high/low and modulating burners
which use an interrupted pilot. Repeat the ignition cycle a few times to ensure a fast ignition and stable pilot
8. Open the main manual shut-off valve and set the high/low limit switch and the modulating controller so that after
establishing a main flame, the burner will travel to high fire. Start the burner. In high fire, check the manifold
pressure with the required pressure for the firing rate, (see suggested inspection list) and if necessary, adjust
pressure regulator. Readjust the air damper if fire looks to lean or too rich.
9. Take a gas meter reading and readjust manifold gas pressure if necessary. Take a CO
and a CO reading.
should be between 8-1/2 and 9-1/2 % and O
should not be more than 5%, both with a maximum CO reading
of .04%. Readjust air damper accordingly.
10. With high/low and modulating burners, mark the high air damper position and set the high/low limit control or
modulating control so that the burner travels to low position. Visually adjust the input adjuster on the main gas
shut-off valve actuator if low fire is too rich or too lean. Take gas meter reading and readjust the input adjuster
according to the required low fire input, but not less than indicated in the specifications table. In order to keep
the high fire setting unchanged when adjusting the low fire air damper position, drive the burner to high fire,
change the positioning of the linkage as indicated in “Low Fire Adjustment”, drive the burner back to low fire
and check the CO
readings. Repeat this procedure until a satisfactory setting is obtained.
11. Make sure all linkage connections are tight and check the readings in high and low fire again.
11a. The motor is allowed to over run with the spring linkage. Set the travel on the Johnson motor to ensure it does
not go too far, or damage to the motor could occur.
12. Reset controller and limits to their desired settings.
DO NOT ADJUST FLAME VISIBLY. INSTRUMENTS ARE THE ONLY SAFE AND
RELIABLE MEANS TO DETERMINE THE PROPER ADJUSTMENTS.
