Installers servicing compatible Rheem models

This part suits technicians replacing the gas control on heaters using part numbers G75-75N-2, G75-75N-3, T75-75N-2, T75-75N-3 or 2VRE3. It is not for technicians working on propane-fired units or heaters with different connection sizes or control interfaces.

75,000 BtuH maximum heating capacity

The thermostat is rated for a maximum heating capacity of 75,000 BtuH. Verify that the appliance nameplate matches this rating before installation. A mismatched capacity will prevent proper burner modulation and safety shut-off.

Questions about this item

What size NPT inlet and outlet connections does the AP14732A gas control thermostat require for mounting?

The unit has a 1/2 in NPT inlet and a 3/4 in NPT outlet for piping connections.

How is the AP14732A installed on a compatible water heater and what step is often missed?

Thread the control into the tank's gas inlet using the 1/2 in NPT connection, then attach the 3/4 in NPT outlet to the burner line; the step often missed is setting the temperature dial to the desired level up to 180 Degrees F before lighting the pilot.

When will the AP14732A need replacement and what indicates it?

Replace the thermostat if the water temperature cannot be held at the set point up to 180 Degrees F, if the pilot will not stay lit, or if the gas valve fails to open when the control calls for heat.
