FOAMING
The
WATER MAZE
uses a high volume of air to operate
the burner, which pushes the heat out of the sparger
tube and into the evaporation tank. There, the air goes
through baffle screens to break the air bubbles down
into smaller sizes. This process can cause excessive
foaming from the detergent used in the washing process
if it has any kind of foaming agents. This foam interferes
with the evaporation process of the
WATER MAZE
and
the foam will go up the stack causing problems with the
venting of the
WATER MAZE
.
The best solution is not to use detergents or cleaning
compounds that cause foaming. An anti-foam pump is
a standard feature on this machine.
WATER BLAZE
has
defoamer chemicals available, developed for use in the
evaporator.
CONVERTING NATURAL GAS
TO L.P. GAS
WARNING: Before converting
from natural gas to L.P. gas, be
certain that the evaporator is shut
down, the water has been cooled,
the gas line is shut off and the
power is disconnected.
The
WATER MAZE
can be ordered
from the factory in natural gas or
L.P. gas. Once they are in the field,
you must order a conversion kit to
change from natural gas to L.P. gas
or from L.P. gas to natural gas.
WB-50/120:
The conversion kit for the WB-50/120, natural gas to
L.P, is # 7-8112.
Remove the SBO-D-7 and replace it with SBO-C-3.
(See items 19 and 21 on pages 42 & 43.) Change the
regulator orifice. Remove the 5/8" orifice and replace
with the 1/2" orifice.
To replace the orifice, disconnect the 3/4" gas line at the
unions above and below the metering orifice. Remove
the section of pipe by unscrewing it from the orifice and
then remove the orifice by unscrewing it from the pipe
above it.
Install the new orifice by applying pipe sealant to the
pipe coming from the gas solenoid valve and screw the
orifice to the pipe. Apply pipe sealant to the section of
pipe that was removed and screw it into the bottom of
the orifice. Reconnect at the unions.
NOTE: Be certain that the orifice is installed right side
up or the system will not work properly. The orifice has
an arrow indicating the flow. If there is not an arrow, look
on the side of the orifice where the plugs are located.
One has green paint around it, the other has red paint.
The plug with green paint goes on the top.
Change the regulator orifice in the gas regulator from
1/2" for natural gas to 3/8" for L.P. gas. Remove the
regulator at the unions. The orifice sits in the tee below
the regulator unions. Use a 1" socket with an extension
to remove the orifice. Put the new 3/8" orifice in. Replace
the regulator.
Replace the
“Natural Gas Only” label with the “L.P.
Gas Only” label.
