DRAIN CONNECTION
The steam vent assemblies are constructed of 2”
DWV copper piping reduced to 1-1/2 DWV pipe. If
the vent system is not purchased a s an option
(R9381), Blodgett Combi recommends plumbing
the oven as show n in Figure 7.
The steam vent should be run to an open floor
drain avoiding flexible hose that could sag and al-
low trapped water to accumulate. The customer
must supply the piping from the oven to the drain.
Connect the drip pan drain to the steam vent with
1.125 I.D. hose.
Use the drain vent assembly and a 2” (50.8mm)
pipe for drain connection.
