Carbon monoxide and combustible gases are dangerous, and in high concentrations can be fatal. It is important to the safety of the customer
and technician to test for both. Measuring CO levels and testing for combustible gas leaks should be part of a routine maintenance schedule
and performed regularly. Remember, CO is odorless and can only be detected using the proper test instrument.

Use the 621C3 to:
Single Input
adjust appliance regulators; set delivery pressures; make regulator
adjustments for pressure and lock-up tests; test pressure switch
operation on 2-stage gas furnace in positive and negative pressures;
test air flow static pressure drop; draft pressure measurements; and
check static pressure in exhaust stack when installing high efficiency
gas hot water heaters.
