the LA22RA100 replaces several legacy part numbers

but shorter trials are generally safer for smaller combustion chambers

effectively breaking the electrical circuit to the gas valve or heating elements if the plenum temperature exceeds safe operating thresholds

a dedicated vacuum-to-electric transducer is necessary

this specific model is a heat-only configuration with an "Off" position
