GlobalTowne still has a few of the Bosch FX Termination Hood's (FXHOOD) left in stock. These FX Hood's were used to vent the older Bosch 125FX and 240FX gas tankless water heaters. The FX Hood is a 4" diameter termination hood for venting out the sidewall. The FXHOOD had a flapper inside to keep the cold out when the unit is not in operation. The FX Hood is made of galvanized metal.
The current replacement for the Bosch Aquastar 125FX is the Bosch Therm 520PN with an AQ4 side wall vent kit.
