2. Turn the inner adjustment screw clockwise to decrease
or counter-clockwise to increase the pilot flame.

possible gas leakage.
Gas Vents
Gas heated machines are supplied with flues. These flues
do not need to be connected to any external vents. The
flue temperature is controlled by the thermostat located
inside the control box.
Steam Injected Heaters
Incoming steam supply line must be connected to the
steam connection (line strainer) labeled “incoming
steam”. Blakeslee recommends installing a steam shutoff
valve and steam regulator (not supplied) close to the
dishwasher to aid in servicing. The wash tank water
temperature is controlled by the thermostat located
inside the control box.
Steam Coil Heater
Incoming steam supply line must be connected to the
steam connection (line strainer) labeled “Steam Supply”.
Blakeslee recommends installing a steam shutoff
valve and steam regulator (not supplied) close to the
dishwasher to aid in servicing. The wash tank water
temperature is controlled by the thermostat located
inside the control box.
Connect the condensate return line or drain (depending
on local codes) to the steam trap.
CAUTION
The condensate return line must run parallel or
on a downward slope from the dishwasher. If the
condensate must be run vertically, a condensate
pump system (not supplied) must be installed.

WARNING
Before performing any service that involves electrical
connection or disconnection and/or exposure to
electrical components, always perform the Electrical
LOCKOUT/TAGOUT Procedure. Disconnect all circuits.
Failure to comply with this procedure can cause
property damage, injury or death.
Note: The dishwasher will supply a switch signal only. A
relay must be installed. The switched signal is used
to energize the relay coil. The Normally Open (NO)
contacts on the relay can be powered by L1 and
ground. Normally this would be a neutral if available.
