BLODGETT 900 Series Roasting Baking Amp Pizza Oven Instruction Manual
Installation
Oven Description and Specifications
The 900 Series enjoys the distinction of having the lon- gest continuous
production run of any oven manufactured by the G. S. Blodgett Company since
its founding in 1848.
The first 900 oven was marketed in 1940 and while ad- vancements in metallurgy
and more convenient and reli- able controls have been incorporated over the
years, the basic design of this unit has remained unchanged since its
inception.
In establishing this record, the 900 Series has set industry wide standards
for excellence in baking characteristics, performance, and reliability. In its
primary applications, it remains unsurpassed for product quality. Simplicity
of de- sign and quality construction throughout assure years of trouble-free
service if equipment is installed properly and given minimal periodic
maintenance.

Oven Assembly
CASTER ATTACHMENT
- Bolt supports to oven with 1/2-13 hex head bolts (casters with brakes should be facing front of oven.)
- Carefully place oven onto the casters. (It will be necessary to have several persons lift oven off the pallet and set it onto the casters). Engage brakes on front casters.
NOTE: A fixed restraint must be provided if casters are used in conjunction
with a flexible connector for movable appliances.
This restraint must secure the oven to a non-movable surface to eliminate
stress on the connector. If the oven is moved, the restraint must be
reconnected after the oven is returned to it’s normal position.
DOUBLE SECTION ASSEMBLY
- Place lower section in predetermined place of installation.
- Attach the legs (and casters if applicable) as previously described.
- Using two 1” boards, place one near the edge of the oven and the other at the far side of the flue collar.
- Lift the upper section and place on the boards. Push the top section across until the sections are even.
- Remove the board from one side by placing a 2” x 4” approximately four feet long under the angle frame. Lift to remove the board.
- Remove the other board in the same manner as above, allowing the upper section to come gently to rest in the proper position.
- Install gas back-pipes and pressure regulator.
- Install the canopy or direct type vent as appropriate.
- Remove all tags.
- Level the ovens side to side and front to back by placing a spirit level on the base frame of the lower section and screwing the adjustable leg feet in or out as appropriate.
ULTRA ROKITE DECK
- Slide the Ultra Rokite shelf through the door opening. Rest the shelf on the deflector and slide to the rear of the oven until it drops into the shelf support.
- Refer to pre-heating instructions supplied with Ultra Rokite.
NOTE: Because of the weight of the Ultra Rokite shelves, take care to avoid
injury to yourself or damage to the shelves when sliding sections into the
oven.
NOTE: For model 981, Ultra Rokite is only available as a bottom deck. DO NOT
install the Ultra Rokite in the top baking compartment of a 981.
STEAM INJECTION
As an optional feature, all 900 Series ovens may be sup- plied with steam jets for baking hard rolls, and vienna, french or other hard crusted breads. This item is also available as a kit which may be installed in the field. To a baker, steam actually means an atmosphere of water vapor. Therefore, it is very important that the steam be low pressure (2-1/2 to 3 PSI), that condensate be taken from the steam line before it enters the oven, and that the steam be sufficiently saturated to give the vapor cloud effect required.
At least one quarter boiler horsepower for all large 900 Series compartment (42” x 32”) or two small 900 Se- ries compartments (33” x 22”) is recommended. Several firms manufacture electric and gas fired steam genera- tors ranging in size from 1/2 boiler horsepower upward. If the steam generator is mounted adjacent to the oven, line transmission losses will be insignificant. If the steam source is located a considerable distance from the oven, line transmission losses must be considered in determin- ing the proper size of the steam. Please refer to the ac- companying diagram for the recommended installation of the steam injection system.
WARNING!!
Gas Flame in oven must be turned off when steam is in use.
Ventilation
Blodgett gas deck ovens are direct fired. Heat and flue products from the
burners are introduced directly into the baking compartment. As a result,
improper venting can have a detrimental effect on the baking characteristics
of the oven. A properly designed ventilation system will allow the oven to
function properly, while removing un- wanted vapors and products of combustion
from the op- erating area.
This oven may be vented using either:
- A mechanically driven, canopy type, exhaust hood, or
- A direct flue
U.S. and Canadian installations
Refer to your local ventilation codes. In the absence of local codes, refer to the National ventilation code titled, “Standard for the Installation of Equipment for the Remov- al of Smoke and Grease Laden Vapors from Commercial Cooking Equipment”, NFPA-96-Latest Edition.
General export installations
Installation must conform with Local and National instal- lation standards.
Local installation codes and/or require- ments may vary. If you have any
questions regarding the proper installation and/or operation of your Blodgett
oven, please contact your local distributor. If you do not have a local
distributor, please call the Blodgett Oven Company at
0011-802-658-6600.
The Blodgett Oven Company cannot assume responsi- bility for loss or damage
suffered as a result of improper installation..
WARNING:
Failure to properly vent the oven can be haz- ardous to the health of the
operator and may result in operational problems, unsatisfactory baking and
possible damage to the equip- ment.
Damage sustained as a direct result of im- proper ventilation will not be
covered by the Manufacturer’s warranty.
CANOPY TYPE EXHAUST HOOD
A mechanically driven, canopy type exhaust hood is the preferred method of
ventilation.
The hood should be sized to completely cover the equip- ment plus an overhang
of at least 6” (15 cm) on all sides not adjacent to a wall. The distance from
the floor to the lower edge of the hood should not exceed 7’ (2.1m).
The capacity of the hood should be sized appropriately with provisions for an
adequate supply of make up air. Capacity is generally expressed in ft3/min
(CFM). 1 CFM of natural gas burned with just enough air for complete
combustion produces 11 CFM of combustion products. In virtually all appliances
some excess air is used. This volume of excess air is added to the flue
products flowing from the appliance.
NOTE: Consult your local exhaust hood contractor for your specific installation.
Installing the canopy hood draft diverter
Ovens ordered for hood venting are supplied with a draft diverter. Install the draft diverter as follows:
- Place the diverter over the flue connector with the open area facing the front of the oven.
- Secure both ends with the sheet metal screws pro-
DIRECT FLUE ARRANGEMENT
When the installation of a mechanically driven exhaust hood is impractical the oven may be vented by a direct flue arrangement
WARNING!!
It is essential that the direct flue be installed as follows. Incorrect
installation will result in unsatisfactory baking and oven damage.
The flue must be class B or better with a diameter of 6” (15 cm). The
height of the flue should rise 6-8 ft (2-2.5 m) above the roof of the building
or any proximate structure. Never direct vent the oven into a hood. The flue
should be capped with a UL Listed type vent cap to isolate the unit from
external environmental conditions.
The direct vent cannot replace air consumed and vented by the oven. Provisions
must be made to supply the room with sufficient make-up air. To increase the
supply air en- tering the room, a ventilation expert should be consulted.
Installing the draft hood
Ovens ordered for direct venting are supplied with a draft hood. Install the draft hood as follows:
- Place the draft hood over the flue
Secure both ends with the sheet metal screws pro- vided.
VENTING PROBLEMS
Blodgett gas deck ovens use the natural principal of heat rising as the basic method of ventilation. If the venting of any deck oven is either restricted or forced in any way the baking characteristics of the oven will be adversely affected.
Examples of forced venting include:
- installation of a fan in a direct vent pipe
- use of a canopy type hood without the draft diverter
Examples of restricted venting include:
- use of tees and elbows
- long horizontal runs

GAS PIPING
A properly sized gas supply system is essential for maxi- mum oven performance. Piping should be sized to pro- vide a supply of gas sufficient to meet the maximum de- mand of all appliances on the line without loss of pressure at the equipment.
Example:
NOTE: BTU values in the following example are for natu- ral gas.
You purchase a Model 911 deck oven to add to your exist- ing cook line.
- Add the BTU rating of your current
Pitco Fryer 120,000 BTU
6 Burner Range 60,000 BTU
Deck Oven 50,000 BTU
Total 230,000 BTU
- Add the BTU rating of the new oven to the
Previous Total 230,000 BTU
911 20,000 BTU
New Total 250,000 BTU
- Measure the distance from the gas meter to the cook This is the pipe length. Let’s say the pipe length is 40’ (12.2 m) and the pipe size is 1” (2.54 cm).
- Use the appropriate table to determine the total ca- pacity of your current gas
The total capacity for this example is 320,000 BTU. Since the total required
gas pressure, 250,000 BTU is less than 320,000 BTU, the current gas piping
will not have to be increased.
NOTE: The BTU capacities given in the tables are for straight pipe
lengths only. Any elbows or other fittings will decrease pipe capacities.
Contact your local gas supplier if you have any questions.
