Equipment Installed At High Altitudes; Air Supply And Ventilation - Dean SM20 Installation & Operation Manual

2.5 Pre-Installation (cont.)
Installation Standards
C.
1. CE/EXPORT STANDARDS: Fryer installation must conform with local codes, or in the
absence of local codes, to the appropriate national or European Community (CE) standards.

2.6 Equipment Installed at High Altitudes

A. The fryer input rating (kW/hr) is for elevations up to 2,000 feet (610-m). For elevations above
2,000 feet (610-m), the rating should be reduced four-percent for each additional 1,000 feet (305-
m) above sea level.
B. The correct orifices are installed at the factory if the operating altitude is known at the time of the
customer's order.

2.7 Air Supply and Ventilation

Keep the area around the fryer clear to prevent obstruction of combustion and ventilation airflow.
A. Do not connect this fryer to an exhaust duct.
B. Correct installation and adjustment will ensure adequate airflow to the fryer system.
C. A commercial, heavy-duty fryer must vent its combustion wastes to the outside of the building.
A deep-fat fryer must be installed under a powered exhaust hood, or an exhaust fan must be
provided in the wall above the unit, as exhaust gas temperatures are approximately 427-538°C
(800-1000°F). Check air movement during installation. Strong exhaust fans in the exhaust hood
or in the overall air conditioning system can produce slight air drafts in the room.
D. Do not place the fryer's flue outlet directly into the plenum of the hood, as it will affect the gas
combustion of the fryer.
E. Never use the interior of the fryer cabinet for storage or store items on shelving over or behind
the fryer. Exhaust temperatures can exceed 427ºC (800°F) and may damage or melt items stored
in or near the fryer.
F. Adequate distance must be maintained from the flue outlet of the fryer(s) to the lower edge of the
filter bank. Per NFPA Standards No. 96, a minimum of 18-inches (45-cm) should be maintained
between the flue(s) and the lower edge of the exhaust hood filter.
G. Filters and drip troughs should be part of any industrial hood, but consult local codes before
constructing and installing any hood. The duct system, the exhaust hood and the filter bank must
be cleaned on a regular basis and kept free of grease.
