C
If the rod travels less than1/2", the piston is not
moving freely within the liner and they must be
cleaned:
1. Remove the control section assembly, top
cap and thermostat.
2. Unthread the liner from the cap (it is glued
together; the o-rings must be removed and
heat should be applied to melt the glue and
loosen the liner).
3. Clean the piston and liner with any cleaner
suitable for brass and stainless steel (400-grit
sandpaper may be used to polish and hone
the piston and liner).
WARNING To prevent injuries, use proper protective
equipment for eyes and skin when using
a propane torch.

Insert a 7/16" dia. rod into the valve and into the
piston overheat chamber. Mark the length of the
rod inside the valve. Push the rod until the piston
stops and mark the new length.

Push the mechanism up and down several
times to make sure the piston moves smoothly
and consistently. If it is not consistent, repeat
Procedure C until it moves freely, or replace.
Contact your Bradley representative and ask for

Remove the valve’s top cap and pull out the
