In a BlazeMaster CPVC fire sprinkler system, sprinkler heads are attached to the system using an approved or listed solvent cement. A medium amount of solvent cement should be applied to the inside of the adapter and exterior of the adjoining pipe.

Push the adapter in place while giving it a quarter turn to ensure even solvent cement application. Allow the adapter the proper amount of time to set and cure. The force of turning the sprinkler head in place can damage a joint that hasn’t been properly cured.

Check the solvent cement manufacturer’s label for proper set and cure times based on environmental conditions.

Always attach the adapter before inserting the sprinkler head. This helps to avoid wet solvent cement dripping into the sprinkler head and clogging the opening.

2. Prepare the Sprinkler Head

Examine the sprinkler head outlet threads to ensure they are clean and free of anything that can disrupt the seal or damage the gasket. This may include sealant, paint and/or tape.

Once inspected, if needed, apply a compatible thread tape sealant to the outlet’s connecting threads. TFE thread tape is the recommended sealant for CPVC connections. This sealant creates a watertight seal, preventing leaks and maintaining system pressure.

DO NOT use a combination of tape and thread sealant on the same joint.

Insert the sprinkler head into the adapter socket and hand tighten in place. Next, take an open-ended or sprinkler head wrench and give a maximum of one to two full turns until the head is properly aligned with the covered area.

Over torquing the sprinkler head can damage and even crack the adapter, rendering it useless.

After all the sprinkler heads have been installed, you can pressurize the system and inspect all the sprinkler heads to ensure leak free installation.
