WATER CONNECTION
Connect the appliance to quality water (refer to
specs below) via a pressure hose with 3/ " (19mm)
couplings. The water pressure needs to be beĆ
tween 30 psi (min) and 50 psi (max). All ovens are
supplied with a water manifold which allows for
one, cold water only connection to the oven. This
water connector must have a brass water restrictor
attached to it, which is part of the manifold assemĆ
bly. Should a customer wish to supply treated waĆ
ter to the steam generator, a kit can be added to the
oven which supplies a plug for the water manifold
and a separate water flow restrictor.
Water must meet the following minimum requireĆ
ments:
DTotal Dissolved Solids (TDS) content will not
exceed 30 parts per million.
DWater PH must be 7.0 or higher.

DOOR ADJUSTMENTS
NOTE: When making door adjustments, always
adjust the hinge side first.
1. Swing the door so it just hits or runs into the catch
on the left hand side of the door. DO NOT latch the
door handle to the catch on the oven body. The
left hand side of the door should just be touching
the gasket evenly from top to bottom.
Adjusting the Hinges
NOTE: If you need to adjust the hinges, always adĆ
just the to hinge first.
NOTE: The hinges on the door have no adjustment,
you can only adjust the hinge on the oven.
1. Adjust the top hinge as follows:
A.) Loosen the three allen head bolts on the
top hinge attached to the oven.
B.) Tap the hinge in or out as needed. Keep the
hinges parallel as shown in FIGURE C.
C.) Tighten the three allen head bolts
2. Adjust the bottom hinge as follows:
A.) You must remove the weight of the door
from the bottom hinge to adjust it. To reĆ
move the weight from the hinge, slide a
screwdriver head into the gap where the
two top hinges touch and pivot. Lift up the
door slightly.
A.) Loosen the three allen head bolts on the
bottom hinge attached to the oven.
B.) Tap the hinge in or out as needed. Keep the
hinges parallel as shown in FIGURE C.
C.) Tighten the three allen head bolts.
D.) Remove the screwdriver to lower the door.
Adjusting the Catch
Adjust the catch as follows:
1. In the top of the door handle is a round roller.
Swing the door until the door handle is close
to the catch on the oven.
2. Loosen the two bolts holding the latch to the
face of the appliance.
3. Adjust the catch from side to side until the
head of the catch is centered with the roller.
. Adjust the catch up and down. There should
be a small clearance between the wheel on the
door handle and the tooth of the catch on the
oven. See FIGURE 5. In most cases the catch
will be all the way up.
5. Tighten the two bolts that hold the catch in
place.
6. For easy alignment, swing the door close to the
catch. Use a felt tipped marker on the door
handle to mark the catch position.
7. Adjust the top of the catch in and out. Adjust the
top of the catch so that the door closes firmly.
8. Tighten the single catch bolt.

Checking Door Adjustment
NOTE: When the door is adjusted ro erly, you
should be able to close a dollar bill beĆ
tween the door and gasket on all four sides
of the door and still be able to ull it out. If
you cannot, the door is too tight, and must
be readjusted.
1. Check the closing of the door in the steam
mode.
2. Next check the closing of the door when the
oven is heated to 37 _F.
3. The door should close easily in both condiĆ
tions. If it does not, the door is too tight and
must be readjusted.
FINE TUNING A DOOR GASKET
Use the following procedure if the door shuts well
in both hot air and steam, but, you still have a little
steam leaking from the door gasket:
1. Make a note where the steam is leaking.
2. Take a tube of silicone and lay a bead out on
a flat surface. Let it dry.
3. Tack the bead behind the door gasket with a
couple of dabs of silicone. This pushes the
gasket out enough to seal the steam leak and
does not over tighten the door.
OR:
1. If you look behind the gasket, it is held in place
with a metal bar with screws. Change the
screws behind the gasket where it is leaking to
10/2 round head screws. Use stainless
screws and put NEVER SEAZE on the threads
so they won't bind.

BC14G TROUBLESHOOTING GUIDE
In the following troubleshooting guide, the scheĆ
matic is broken down into areas. This allows the
oven to be checked in sections.
When troubleshooting, slide the control panel out
and use your volt meter. The main control circuit
voltage for all Synergy ovens is 230 volts. Once the
problem is determined, it is often easier to remove
the slide out from the oven completely to change
components. To remove the slide out, disconnect
the hot air thermostat probe, ground wire, and
large brown plug in connector.
NOTE: Always troubleshoot a Synergy oven in the
following sequence: COOL DOWN, HOT
AIR, STEAM, and then COMBI. Reference
the text that follows with the a ro riate
troubleshooting schematic to hel you
troubleshoot each mode.

NO OPERATION WITH THE MODE SWITCH IN
STEAM
1. Check power at terminal 6 on the mode switch.
See FIGURE 1, location (H). If no power, return
to NO OPERATION WITH THE MODE SWITCH IN
HOT AIR. Your problem is most likely a bad
mode switch position. If power is 208V, proceed.
NOTE: The hot air is cycled on in the steam
mode to boost tem erature.
2. If the steam logo by the mode switch is illumiĆ
nated, jump to STEP 10.
3. If the low water light in the lower right hand corĆ
ner of the control panel stays on, jump to NO
FILLING OF STEAM GENERATOR.
. If hot air light not lit on P5 check P5 temp conĆ
troller for voltage. See FIGURE 3, location (B).
5. Check thermostat P5. See FIGURE 3, location
(A).
6. Check that relay R205 contacts 9 to 5 are
closed. Check coil and contacts for proper opĆ
eration. See FIGURE 3, location (I).

See FIGURE 3, location (I).
13. Check input and output of T5 solid state timing
relay. See FIGURE 3, location (J).
The rest of the ignition circuit for the HOT AIR boost
was proven when you trouble shot the hot air mode.
NO FILLING OF STEAM GENERATOR
1. Verify water is on to Synergy oven and flowing
through water restrictor.
2. Check mode switch positions , 10, and 22.
See FIGURE 7, location (A).
3. Check input and output to fast LLC (Low Level
Control) float. The LLC is the long float. See
FIGURE 7, location (B).
. Check relay R20 , coil, input and output. See
FIGURE 7.
5. Check fast fill solenoid. See FIGURE 7, locaĆ
tion (D).
6. Verify hot water slow fill is operating. See
FIGURE 7, locations (E) and (F).
NO OPERATION WITH THE MODE SWITCH IN
COMBI
Most of this circuit has already been trouble shot
by proving the HOT AIR and STEAM mode work.
1. Check T2 combi solid state timing relay input
and output. See FIGURE , location (A).
NO ON DEMAND STEAM
Set time out and press ON DEMAND STEAM button.
1. Check S9 on demand steam button. See
FIGURE 5, location (A).
2. Check input and output to T3 solid state timing
relay. See FIGURE 5, location (B).
3. Check relay R202 coil and contacts. See
FIGURE 5.
NO FLUSH / DRAIN MODE / MANUAL OR AUTO
The T flush/drain solid state timing relay is enerĆ
gized when the P11 flush disable snapĆdisk is
closed. Both of these parameters must be met for
the manual flush/drain switch to work.
NOTE: When the P11 flush diable sna Ćdisk is
closed the steam generator is below 160_F
(71_C) and the oven is in the OFF osition.
1. Check the deliming switch (S15) is in the off
position. See FIGURE 6, location (A).
2. Check that P11 contact are closed. See
FIGURE 6, location (B).
