CAUTION
Before you attempt to use the BTU measurement system, isolate the main unit, open the bypass
and flush the entire system so that it is free of flux, solder, pipe and tube cuttings and any other
free moving particles.
Installing the meter body
1. Make sure the unions are free of nicks or scratches on either end of the flow
meter body and on the process connections.
2. Spray the union faces with a silicone spray or apply a thin coat of beeswax to enhance
seating. Do not use paste thread sealant on union faces.
3. Orient the flow arrow on the meter with the direction of flow.
4. Recommended torques for union seal: 70 ft/lbs minimum
5. Make sure alignment of pipe does not put lateral stress on either joint.
