2. Detach the thermocouple from the interrupter block by unscrewing the
thermocouple nut.
3. Detach the two leads from the interrupter block making sure to pull on the base of

with the larger tag (From the receiver) is furthest away from the valve body.
4. Remove the interrupter block by unscrewing from the gas shut-off tap.

block when it is fully tightened to the gas shut-off tap, slacken it and rotate to allow
the leads to be fitted. Retighten making sure that the leads remain in place in the
interrupter block. Fit and tighten the thermocouple nut making sure that the leads are
secured in the interrupter block to give a good electrical contact. Do not over tighten
the thermocouple nut.
