6.2.3 Water drain
Rules for safely installing the drain connection
In order to prevent hazards related to an improperly installed drain connection, make sure to observe
the following rules:
■
The drain pipes must be made of PVC or copper and must be able to withstand a temperature of
140 °F.
■
The drain pipe must not taper or have any other diameter-reducing deformations at any point.
■
The drain pipe's minimum diameter will depend on the pipe's total length and the number of elbows
used. For a pipe length of up to 6 feet and a maximum of two elbows, the minimum inner diameter
will be 1½". For a pipe length of 6 to 12 feet or a maximum of three elbows, the minimum inner
diameter will be 2".
■
The drain pipe must have a downward slope of at least 5% (3°).
■
The unit drain must not be directly connected to the sewer system vertically.
■
The connection between the drain pipe and the sewer system must be located outside the perime‐
ter of the unit's base area. Due to potential wastewater vapors, there must not be a drain connec‐
tion or open sewer line below the unit's base area.
■
The drain connection must be implemented using a rigid, naturally ventilated pipe.
■
A ventilation clearance of at least 1" must be maintained between the end of the drain pipe and the
upper edge of the drain or pan.
■
No other units may be connected to the combi oven's drain pipe.
■
The combi oven must not be connected to any other units' drain pipe.
