➀ Consult the O.E.M. for replacement type number
➁ Suggested replacement type may have different panel conguration. Some controls experienced
modication. Determine proper wiring with the aid of panel diagrams A through G.
➂ Note: Panel type C features an Electrical Quick Shut-Off Resistor (see diagram)
CONTRACTOR TIP: Mercury ame sensors can only be replaced by cross referencing the
original mercury ame sensor model number. They can not be replaced by gas valve model
number.
