Installing a type 2 manifold
If you are replacing a Type 1 manifold with a Type 2 manifold, order the
accessory kit, G1570-60720. This kit contains a new pneumatics control board
bracket that is required for the Type 2 manifold. See also Replacing the PCB
bracket.
WARNING Hydrogen gas is flammable and potentially explosive. Before replacing the
manifold, turn off the hydrogen gas at the source.
WARNING Before proceeding, turn off the oven and any heated zones and let them cool
down. Turn off all detector gases at their supply, then turn off the main power
switch and unplug the power cord.
Caution Always hold the manifold as shown below to avoid damaging board
components.
