Start-Up Procedures

SMOKE CANDLE TEST – VENTILATION SYSTEM
VERIFICATION
Performance will be evaluated during Start‑up Checkout
by conducting a smoke candle test. The hood must capture
all smoke from the oven. This is required to assure proper
performance of the oven and to eliminate additional service
calls that occur when ambient temperatures are too high.
In all cases, the ambient temperature around the oven
must be less than 95°F/35°C when the oven is operating.
In certain localities, other chemical or gaseous methods
of detecting adequate capture will be the requirement to
meet the local code authority.
Oven Setup for this Test:
• This test is to be done on the bottom oven of a multiple
oven system, or a single oven.
• The conveyor must be off.
• The oven temperature must be set and operating at
550°F/288°C.
Test Procedure:
NOTE: Use Lincoln Smoke Candle #369361 (in Australia, an
alternate method of coloring the air may be used).
1. Wear heat resistant gloves to prevent burns to your
hands.
2. Put the smoke candle in a cake pan approximately
8 inches (200 mm) x 8 inches (200 mm) x 2 inches
(50 mm) deep or equivalent.
3. Open the optional access window in the oven door, or
insert candle through conveyor opening.
4. Light the fuse of the smoke candle and immediately
put the pan and candle into the center of the oven
cavity, on the conveyor belt. (Close the access window
or door.)
5. Observe the smoke pattern coming out of the oven
openings and the collection of this smoke by the
ventilation system.
6. The ventilation system must capture all the smoke from
the oven.

FINGER HOUSING BAFFLE PLATE ADJUSTMENTS

The finger housing has a baffle mounted inside to balance
the air flow to the rear and front of the oven. If the product
is cooking more or less in the rear of the oven than in
the front, it is possible the finger housing baffle needs
to be adjusted. If it is deemed necessary to adjust the air
balancing baffle, be sure to adjust all eight finger housings
to exactly the same opening. Determine if more air (heat)
is required at front or rear of oven, then open or close
off that air by bending the baffle in the proper direction.
For additional information on how to adjust the Finger
Housing Baffle Plate, contact the Lincoln Technical Service
Department at 1‑824‑724‑2273.
