Description

This 4kW PDR Titanium Heater is the current replacement for all 2003-2009 4kW No-Fault Heaters. If you’re replacing a 76228 Titanium Heater (pressure switch version) you’ll need to add a pressure switch bypass jumper 72768. For the 6kW (6000 watt) version, please see the 73790.

Note:  It is highly recommended to purchase new thermistors, 79006and 79005, with this heater. The inlet thermistor port on these style heaters may require a wrench to thread in the thermistor. If your existing thermistors plug in to the OUTSIDE of your control box, please use item 78970 and 78969 as replacement thermistors. This heater comes with new thermistor o-rings.
