INTRODUCTION
The US 7910 adaptor baseplate together with an MMI 810
model 32 / 33 or TTI 790 model 33 can be used to replace
an old GBR 681 unit.
It is not necessary to rewire the burner system. In two-stage
burners, valve 2 can be connected to terminal A on the
adaptor baseplate.
The MMI 810 control box then gives the release signal to
the burner second stage approx. 12 sec. after flame establishment.
