1. INTRODUCTION
The Siemens electro-hydraulic gas valve actuators are used in combination with VG series gas
valves to provide safety shut-off control for industrial and commercial burner applications. It is
featured in all double-block and double-block-and-bleed gas trains used in AERCO boilers.
The electro-hydraulic actuator consists of a cylinder filled with oil, a piston containing an electric
oscillating pump, and a relief system. When power is supplied to the actuator, the relief system
closes, and the pump moves oil from the reservoir into the pressure chamber. This action
causes the piston to move downward in the cylinder, opening the gas valve. When power to the
actuator is interrupted, the relief system opens and the gas valve closes in less than 0.8
seconds. A position indicator, visible through the transparent portion of the terminal cover,
shows the entire stroke range of the actuator. A light, which is visible through the lower left
transparent portion of the terminal cover, indicates when the actuator receives power. An
optional, non-adjustable SPDT proof of closure over travel switch signals the closed position
after the gas valve has closed. An optional SPDT auxiliary switch is adjustable between 40%
and 100% of the stroke. The adjustment screw and scale are located on the right side in the
terminal box, and are visible through the transparent portion of the terminal cover.

6. PREPARATONS
To prepare the boiler for the retrofit, perform the following:
• Remove power from the unit by shutting off electrical power upstream from the boiler.
• Turn off the supply gas upstream from the boiler.
WARNING
HIGH VOLTAGES OF 120 VAC, 220 VAC OR 460 VAC
ARE USED IN AERCO BOILERS. IT IS REQUIRED TH AT
ALL POWER APPLIED TO THESE BOILERS IS
REMOVED FIRST BEFORE PERFO RMING ANY OF THE
PROCEDURES DESCRIBED IN THIS DOCUMENT. USE
EXTREME CARE WHEN ACCESSING CIRCUITS AND
ELECTRICAL CONNECTIONS WI THIN THE EQUIPMENT.
SERIOUS PERSONAL INJURY OR DE ATH MAY OCCUR
IF THIS WARNING IS NOT OBSERVED.
IMPORTANT!
Observe local requirements and lockout procedures when working
on the boiler.
Personal injury or loss of life may occur if procedures are not
followed as specified. All installations must be performed by
qualified personnel only.
Do NOT pull the actuator shaft of the actuator.

7. REPLACEMENT PROCEDURE
Replacement instructions for the actuator are as follows:
1. After ensuring that all electrical power is removed from the boiler, remove boiler side panels
as necessary to access the actuator. Depending upon the boiler model, the actuator may be
installed at any angle except upside down. The example shown in Figure 2 is a double-block
gas train.
2. Use a standard Phillips head screwdriver to remove the screw holding the semi-transparent
wiring compartment cover of the old actuator and make a note of all wire connections.
3. After making a note of the wire connections, release the wires from the connections by
pushing down on the spring loaded lever under each wire terminal and remove wires.
4. Pull all loose wires from out of the wire conduit in the side. A spare bushing for the wiring
conduit hole is included in the kit in case it is needed.
5. Remove the four 4mm Allen bolts that hold the actuator to the valve body (Figure 2) and
then remove the actuator.
6. Install new actuator from replacement kit and affix to valve body with 4mm Allen bolts
captured in the body of the new actuator.
7. On all BMK 1.5 – 3000 models, and on BMK 6000 units with the newer actuator shown in
Figure 4, remove the new actuator cover, punch out the holes in the plastic to accommodate
the wiring, then insert the wires through wire conduit and wire it identically to the old
actuator. Skip this step on older BMK 6000 units with the original actuator (which included
an Auxiliary Switch Adjustment Screw) as shown in Figure 5, and complete Step 8, below.

8. Complete this step ONLY on BMK 6000 units with the original actuator, as shown in
Figure 5. Remove the new actuator cover, punch out the holes in the plastic to
accommodate the wiring, then insert the wires through wire conduit and wire it as follows:
• Wire Terminals 4, 5, N, N, L and L identically to the old actuator
• Remove & dispose of the two wires attached to Terminals 1 and 2 and wire nut, and the
wire connecting Terminal 3 to the Low Gas Pressure Switch (dashed lines)
