a 440VAC capacitor can safely replace a 370VAC unit as it has a higher insulation breakdown voltage

this SPST (Single Pole Single Throw) switch ensures the combustion blower is pulling sufficient static pressure before allowing the ignition sequence to proceed

preventing thermal stress on the heat exchanger
