Control Panel and Fan Assembly
1. Align the control panel with the four small holes in the left front jacket panel. Using sheet
metal screws, attach the control panel to the jacket. Insert the capillary tubes (on
Honeywell controls) into the two 3/4 inch wells previously threaded into the control
tappings #10 and #11. Fasten the Honeywell controls to the well using the screw clamp
on the aquastats. NOTE: You may receive 2 - 3/4” x ½” bushings and 2 – ½” wells in
place of the ¾” wells.
2. Remove top front jacket panel. On the EXCEL 2000 model boiler, plug or install “coin”
air vents in tappings #14 and #15 on top of boiler. On the EXCEL 2200 model boiler,
install a “COIN” style air vent in tapping #15 and a vent or plug in tapping #14.
3. Place the 2” thick insulation material (often shipped in the front top jacket panel or found
in the jacket box) on top of the boiler, matching the cutouts with the tappings.
4. Remove the metal bracket protecting the adjusting screw and the draft blower fan flange.
Using the same screws, attach the draft fan to the flange. Refer to the cut-away boiler
diagram on page 8 for proper fan orientation.
Refer to the wiring diagrams on pages 24 - 25 to proceed.
5. Wire the fan to the control panel. Route the fan wires across the insulation on top of the
boiler, under the by-pass damper rod, and through the hole in the left side jacket panel.
Connect the brown wire from the fan to the “F” (HOT) terminal, the blue fan wire to the
“N” (NEUTRAL) terminal and the yellow and green stripe fan wire to the “G” (GROUND)
terminal on the 120volt terminal strip inside the control panel.
6. Mounting the Draft fan low temperature Flue Gas Sensor
a. Mount the junction box to the left of the control panel. Make sure you have
enough cable to make the connections to the S1 and S2 terminals inside
the control panel.
b. Drill a ¼” hole in the top of the smoke pipe within 6” of the boiler flue
collar.
c. Insert the sensing bulb fully into the smoke pipe.
Be careful not to kink
the capillary tube!
Fasten the capillary tube so that the sensing bulb is
held in position.
NOTE:
•
ALL CONNECTIONS ON THE 120 VOLT TERMINAL STRIP INSIDE THE
CONTROL PANEL HOUSING ARE 120 VOLT.
•
ALL CONNECTIONS ON THE EXTERNAL 24 VOLT TERMINAL STRIP ON
THE OUTSIDE LEFT OF THE CONTROL PANEL HOUSING ARE 24 VOLT.
120 Volt Connections To House, Burner and Circulator
All wiring must be completed as per the wiring diagrams on pages 24 - 25.
NOTE: 1. ALL WIRING MUST BE INSTALLED IN ACCORDANCE WITH NFPA STANDARD
#70 AND THE NATIONAL ELECTRICAL CODE.
2. The electrical system of the boiler shall be supplied from a single branch circuit.
3. The boiler itself must be grounded in accordance with the requirements of the
authority with jurisdiction, or, in absence of such authority, in accordance with
the National Code, ANSI/NFPA #70-1978.
