INSTALLATION SPECIFICATIONS/INFORMATION
Before starting to troubleshoot an oven, verify the
oven has been installed correctly. The installation of
the electric and gas connections must be performed
by a qualified installer only. The installation must conĆ
form to all local and national installation standards. A
hood system is required with the BC1 G.

OVEN LOCATION
Certain minimum clearances must be maintained
between the oven and any combustible or nonĆ
combustible construction. See the following table.
The following clearances are recommended for
servicing.
DOven body sides - 12" (30cm)
DOven body back - 12" (30cm)
NOTE: On gas models, routine servicing can usuĆ
ally be accom lished within the limited
movement rovided by the gas hose reĆ
straint. If the oven needs to be moved furĆ
ther from the wall, the gas must first be
turned off and disconnected from the oven
before removing the restraint. Reconnect
the restraint after the oven has been reĆ
turned to its normal osition.
Left Side Heat Shie d
Heat sources should not be near the air vents loĆ
cated on the left hand side of the gas appliance.
Consult the factory for optional protective side heat
shield.

STACKING
WARNING!!
Stacking shou d be performed by qua iĆ
fied insta ation personne on y. The apĆ
p iances are heavy. Take care to use propĆ
er too s and techniques when ifting and
stacking app iances.
1. Remove the drip pan from the top appliance.
2. Attach the legs or casters to the bottom apĆ
pliance.
3. Place the top appliance on the bottom apĆ
pliance. Be sure all four sides are flush.
. Bolt the two appliances together using the
bolts provided.
5. Attach the flue vents as shown.
6. Replace the drip pan.
7. Connect the drain, gas (if applicable) electrical
and water. Refer to page 1-5.
NOTE: An o tional gas lumbing manifold may be
urchased from Blodgett Combi. Order
art number R9570. An o tional drain
lumbing manifold may be urchased
from Blodgett Combi. Order art number
R9381 for single or to ovens.

PLUMBING CONNECTIONS
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.
WARNING!!
Operating the app iance without the water
restrictor insta ed wi inva idate the warĆ
ranty. The use of poor qua ity water wi inĆ
va idate 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.

STEAM CONNECTION FOR BC14GDS
Steam supply line is 3/ " NPT. Steam must be clean,
dry and potable. A particle screen and bucket trap
may be needed and are recommended. 60 lbs per
hour is the maximum usage per oven. Steam supply
pressure should not exceed 0 to 50 psi. The flow
pressure is 1Ć1/2 to 3Ć1/2 psi and is set at the steam
pressure regulator supplied inside the oven.

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.
