What it is
Sensing tubes supplied by Main for use with the air pressure switch on the Multipoint FF water heater family. The tubes carry the pressure signal from the fan or flue path to the pressure switch so it can prove air flow before ignition. They are a service part for the Multipoint FF and Multipoint FF ErP appliances.
Signs this part needs replacing
- Tubes are cracked, split, perished or hardened with age
- Tubes are kinked, collapsed or restricted internally
- Tubes are blocked with debris, condensate or dust
- Tubes are loose or slipping off their connection points
- The pressure switch fails to prove air flow, causing lockout or failure to ignite
Before you order
- Confirm the appliance model is a Multipoint FF or Multipoint FF ErP
- Check the GC number on the appliance data badge against the model listed
- Inspect the existing tubes and their connection points for damage or blockage
- Check the air pressure switch itself before replacing the tubes alone
