LP-754 Instructions 1

Preparing for Installation:

When working on heating equipment, observe all precautions in the

literature, on tags, and on labels attached to the boiler. Follow all

safety codes. Wear safety glasses and work gloves. Have a re

extinguisher available.

DO NOT power or ll the boiler with water. It is best practice to install

this kit BEFORE powering or lling the boiler.

If the boiler IS powered and/or lled with water, turn o power to the

boiler, and valve it o to isolate it from the system. Then drain the

boiler. Close the drain valve after draining.

Valve Orientation:

The valve can be oriented in any position as long as the actuator does

not go below the horizontal plane. See the orientation guide from

Belimo attached to the valve.

Installing the Valve on ELX-400 - 1000 Models:

1. Use pipe dope / tape to thread one of the 2” anges onto the

supply pipe of the boiler.

2. Install the isolation valve using the supplied bolts and washers.

3. Install the other 2” ange to the isolation valve using the supplied

bolts and ange. See Figure 1.

NOTE: A separate service valve MUST be installed for each boiler.

Do not overtighten any of the bolts as this may damage the

threads and prevent the bolts from turning. Replacement bolts are

not included in this kit.

These valves DO NOT qualify as service valves.

Installing the Valve on ELX-1500 - 2000 Models:

Install the isolation valve using the supplied bolts and washers. See

Figure 2.

NOTE: A separate service valve MUST be installed for each boiler.

Valve Wiring:

The valves are supplied with 16 feet of power cable. The power cable is

permanently connected to the valve and cannot be removed.

NOTE: Avoid excess wire length. The power cable may be cut, stripped,

and connected to reduce length. Ensure enough slack to avoid wire

damage.
