3 Product Description
3.5.5 Common Technical Data for Pilot Burner GFI35/48/70/89
NOTICE
The electrical data are identical for all devices, only the air and gas volume flows differ.
1
The product is not permitted to be transported, stored or operated outside the specified range.
Doing so will invalidate any guarantees with regard to safety relevant functions.
2
Provide external spark quenching for inductive loads, do not connect any capacitive loads.
