IMPORTANT SAFETY INSTRUCTIONS
SAVE THESE INSTRUCTIONS!
This manual contains important instructions that should be followed during installation and maintenance
of the Gas Vent Valve (valve). The following are general safety precautions that are not related to specific
procedures and therefore do not appear elsewhere in this publication. These are recommended precau-
tions that personnel must understand and apply during many phases of maintenance.
The valve is electrically actuated. Wherever electricity is present, there is the hazard of electrocution. Like
any other electro-mechanical device, the valve can be dangerous if it is improperly operated or maintained.
