prevents the burner from starting up.
- Performs leak test of the gas shut-off valves before start-up
and/or immediately after burner shut-down
- No inlet gas pressure limitations
- Easy-to-read dial indicates progress of test program
- Ability to eliminate or leak test the vent valve
- Cost effective control improves system safety
- Globally Approved ?cULus, FM, CE
