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 hazardous atmosphere for fusion.
Use a clean non-synthetic cloth to clean the butt fusion heater
adapter surfaces.
Verify heater temperature by noting the reading on the dial
thermometer.
Insert heater between the pipe ends.

Heat Pipe
Shift the selector valve (A) to the center position, and set the
heating pressure (if required). If heating pressure is not required,
set the pressure reducing valve (B) at its lowest setting, or the
drag pressure, whichever is higher.
Shift the selector valve (A) to the fusion position and move
the carriage control valve (C) to the left to bring pipe ends
in contact with the heater. Move selector valve (A) to middle
(heating mode) position. If heater pressure is not required by
pipe manufacturer or joining standard, or opposing forces are
not great enough to move the carriage away from the heater,
shift the carriage control valve to neutral.
IMPORTANT: Always shift into the heating mode before
returning carriage valve to neutral.
Follow the pipe manufacturer's suggested heating and soaking
procedure or joining standard.
