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 con-

form to all local and national installation standards. A

hood system is required with the BC14G.

OVEN LOCATION

Certain minimum clearances must be maintained

between the oven and any combustible or non-

combustible construction. See the following table.

The following clearances are recommended for

servicing.

Oven body sides --- 12” (30cm)

Oven body back --- 12” (30cm)

NOTE: On gas models, routine servicing can usu-

ally be accomplished within the limited

movement provided by the gas hose re-

straint. If the oven needs to be moved fur-

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 re-

turned to its normal position.

Left Side Heat Shield

Heat sources should not be near the air vents lo-

cated on the left hand side of the gas appliance.

Consult the factory for optional protective side heat

shield.

STACKING

WARNING!!

Stacking should be performed by quali-

fied installation personnel only. The ap-

pliances are heavy. Take care to use prop-

er tools and techniques when lifting and

stacking appliances.

1. Remove the drip pan from the top appliance.

2. Attach the legs or casters to the bottom ap-

pliance.

3. Place the top appliance on the bottom ap-

pliance. Be sure all four sides are flush.

4. 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 optional gas plumbing manifold may be

purchased from Blodgett Combi. Order

part number R9570. An optional drain

plumbing manifold may be purchased

from Blodgett Combi. Order part number

R9381 for single or top ovens.

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 be-

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 assem-

bly. Should a customer wish to supply treated wa-

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 require-

ments:

Total Dissolved Solids (TDS) content will not

exceed 30 parts per million.

WaterPHmustbe7.0orhigher.

WARNING!!

Operating the appliance without the water

restrictor installed will invalidate the war-

ranty. The use of poor quality water will in-

validate the warranty.

FIGURE 2

DRAIN CONNECTION

The waste drain assembly must be constructed of

2-inch 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 configura-

tion, the venting on the bottom oven must vent

above the top oven. It is recommended that sepa-

rate drain lines be run on stacked ovens. Refer to

FIGURE 3 for a recommeded water drain configu-

ration.

FIGURE 3

STEAM CONNECTION FOR BC14GDS

Steam supply line is 3/4” 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 40 to 50 psi. The flow

pressure is 1-1/2 to 3-1/2 psi and is set at the steam

pressure regulator supplied inside the oven.

INSTALLATION

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 ad-

justthetophingefirst.

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 re-

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.
