Using a propane-sized orifice on a natural gas system will result in an insufficient pilot flame and system failure

technicians should always install a fresh run capacitor (check motor nameplate for specific MFD rating) when replacing the blower motor to ensure proper starting torque and prevent premature winding failure

while the high-efficiency 3-phase design reduces operational costs

Use only in applications where the control board facilitates dual-speed venting requirements
