TROUBLESHOOTING

SYMPTOM

POSSIBLE PROBLEM

CORRECTIVE ACTION

SMOKE LOSS

Smoke Loss - Hood is not exhausting

properly.

Low Airflow - Static pressure at the

hoods static tap. Static values should

be in accordance with Figure 21.

Broken or slipping belt on the exhaust

fan.

2. Proper rotation of the exhaust fan

wheel.

3. Proper size of the exhaust fan (fan

must deliver nameplate rating).

Ductwork inspection panel left open.

Exhaust duct fire damper not open or

in proper position

B. The hood must have its own exhaust

system and no other exhaust, such

as dishwasher hoods, should be tied

into it.

Inspect duct system and verify that

there are no other non hood systems

tied in. If so, they must be removed.

C. Improperly placed make-up air

diffusers

Make-up air directed at the hood will

likely create cross drafts disrupting

the airflow into the hood. Adjust the

louvers to direct the make-up air away

from the hood.

2. Make-up air should be delivered

through the registers at ceiling height,

and distributed throughout the kitchen

area.

3. Make-up air registers located near the

hood, the louvers should be adjusted

to direct the air away from the hood.

Directing or forcing make-up air at the

hood typically creates cross drafts

resulting in smoke loss. Ceiling make-

up air should not exceed 150 FPM at

the inlet.

Exhaust fan discharge.

There should be no screen over the

discharge. If one is found, it should be

removed.

2. The direction of discharge should

not be into the prevailing winds nor

downward onto the roof. A vertical

discharge is highly recommended.

GREASE EXTRACTION

Poor Grease Extraction

Hoods with too much air being pulled

through them can have grease pull

through.

To see if you are pulling the proper

amount of air through the system, see

Figure 21.

2. Wash XG Extractors more frequently.

3. Noise

B. Hoods pulling too much air through

the extractor can cause excessive

noise.

Adjust motor / fan speed down to

eliminate excessive noise. After

doing so, verify the hood is properly

capturing all smoke.

2. Adjust GBD damper up or down as

needed to eliminate noise. Watch for

changes in other hood’s flow rates as

a result of damper manipulation.
