PLUMBING CONNECTIONS

WATER CONNECTION

Connect the appliance to quality water (refer to
specs below) via a pressure hose with 3/4" (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:

D Total Dissolved Solids (TDS) content will not

exceed 30 parts per million.

D Water PH must be 7.0 or higher.

WARNING!!

Operating the appliance without the water
restrictor installed will invalidate the warĆ
ranty. The use of poor quality water will inĆ
validate the warranty.

DRAIN CONNECTION

The waste drain assembly must be constructed of
2Ćinch copper and be atmospherically vented. The
venting must have a riser so the steam vents above
the top of the oven. In a stacked oven configuraĆ
tion, the venting on the bottom oven must vent
above the top oven. It is recommended that sepaĆ
rate drain lines be run on stacked ovens. Refer to
FIGURE 3 for a recommeded water drain configuĆ
ration.

DOOR ADJUSTMENTS

INSTALLATION

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 top 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 4C.

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 4C.

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.

4. 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 properly, 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 pull 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.

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
10/24 round head screws. Use stainless
screws and put NEVER SEAZE on the threads
so they won't bind.

2. Next check the closing of the door when the
oven is heated to 374_F.

3. The door should close easily in both condiĆ
tions. If it does not, the door is too tight and
must be readjusted.

TROUBLESHOOTING

BC14G

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 appropriate
troubleshooting schematic to help you
troubleshoot each mode.

NO OPERATION WITH THE MODE SWITCH IN
COOL DOWN

1. Verify the deliming switch is in the on position.

2. Verify power is being supplied at the outlet.

3. 115V only - Check fuses in the small pullĆout
fuse holder under the power plug in the rear of
the oven. See FIGURE 1, location (A).

4. 115V only - Check the input and output of the
stepĆup transformer located in the rear of the
oven in the upper left hand corner. In order to acĆ
cess the transformer you must remove the back
panel. A good place to check the output voltage,
before removing the back panel, is at the delimĆ
ing switch on the left hand side of the oven.

5. Check the mode switch. See FIGURE 1.

6. Check the fan speed switch. See FIGURE 1
location (G).

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 temperature.

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.

4. 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).

7. Check F6 high limit. See FIGURE 3.

8. Check that R204 contacts 9 to 1 are closed.
See FIGURE 3, location (E).

9. Check that R202 contacts 1 to 9 are closed.
See FIGURE 3, location (F).

10. Check XFMR1 input and output power. See
FIGURE 3, location (G).

11. Check THS2 ignition module 24VAC. See
FIGURE 3, location (H). If no hot air boost in
the steam mode, check T5.

12. Check that R205 contacts 10 to 6 are closed.
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 4, 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).

4. Check relay R204, 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 4, 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 T4 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 snapĆdisk is

closed the steam generator is below 160_F
(71_C) and the oven is in the OFF position.

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).

3. Check that relay R206 contacts are closed.
See FIGURE 6.

4. Auto Flush/Drain ć Check T4 flush/drain solid
state timing relay inputs and outputs. See
FIGURE 6, location (H).

5. Manual Flush/Drain ć Check S12 flush/drain
switch input and outputs. See FIGURE 6, locaĆ
tion (D).

6. Check R203 relay coil and contacts. See
FIGURE 6, location (E).

7. Check that R204 contacts are closed. See
FIGURE 6, location (G).

8. Check flush/fill solenoid.

NO MEAT PROBE OPERATION

Synergy oven must be on and the timer set to the
stay on position. The meat probe must also be
plugged into the front control panel.

1. Check mode switch terminals 4, 10, and 22.
See FIGURE 4, location (A).

2. Check S11 fuse. See FIGURE 4, location (J).
