dry and potable. A particle screen and bucket trap
may be needed and are recommended. 60 lbs per
hour is the maximum usage per oven. Steam supply
pressure should not exceed 40 to 50 psi. The flo w
pressure is 1-1/2 to 3-1 /2 psi and is set at the steam
pressure regulator supplied inside the oven.

The steam vent assemblies are constructed of 2”
DWV copper piping reduced to 1-1/2 D WV pipe. If
the vent system is not purchased as an option
(R9381), Blodgett Combi recommends plumbing
