Butt Fusion Procedure
Check Heater Temperature
NOTICE: Incorrect heating temperature can result in questionable fusion
joints. Check heater plates periodically with a pyrometer and
make necessary adjustments.
Check heater surface temperature.
Refer to the pipe manufacturer's recommendations for proper heater
temperature.
IMPORTANT: The dial thermometer on the heater indicates internal
temperature which varies from the actual surface temperature.
The dial thermometer can be used as reference once the surface
temperature has been verified.

Inserting Heater
Heater is not explosion proof. Operation of heater
in an explosive atmosphere without necessary safety
precautions will result in serious injury or death.
If operating in an explosive atmosphere, heater should be brought up to
temperature in a safe environment, then unplugged before entering the
explosive atmosphere for fusion.
Use a clean nonsynthetic cloth to clean the butt fusion heater surfaces.
Verify heater temperature by noting the reading on the dial thermometer.
Insert heater between the pipe ends.
