Global Protankless Supply is now carrying the New Bosch Greentherm T9900 & T9800 Condensing Tankless Water Heaters. This is to cover the venting requirements for the indoor model heaters. The Bosch T9900 & T9800 models can be vented horizontally out the sidewall of the home or vertically through the roof. The venting connection and intake hole is on top of the unit and is 2" diameter. The Bosch Greentherm T9900 & T9800 series heaters can be vented using 2", 3" or 4" PVC, CPVC, PP or ABS.
The minimum exhaust pipe length is 1 ft (0.3m) of straight vent pipe. The minimum air intake pipe length is 1 ft or one 90° elbow or an air intake grill cap to prevent debris from falling into the appliance.
See the table below for maximum exhaust and intake lengths:
