1. Use this unit only in the manner intended by the manufacturer.
If you have questions, contact the manufacturer at the address
or telephone number listed in the warranty.
2. Before servicing or cleaning unit, switch power off at service

warning device, such as a tag, to the service panel.
3. Installation work and electrical wiring must be done by qualified
personnel in accordance with all applicable codes and standards, including fire-rated construction codes and standards.
4. Sufficient air is needed for proper combustion and exhausting
of gases through the flue (chimney) of fuel burning equipment to prevent backdrafting.Follow the heating equipment
manufacturer’s guidelines and safety standards such as those
published by the National Fire Protection Association (NFPA),
and the American Society for Heating, Refrigeration and Air
Conditioning Engineers (ASHRAE), and the local code authorities.
5. When cutting or drilling into wall or ceiling, do not damage
electrical wiring and other hidden utilities.

cause smoking and greasy spillovers that may ignite. Heat oils
slowly on low or medium settings.
b) Always turn hood ON when cooking at high heat or when
cooking flaming foods.

to accumulate on fan or filter.
d) Use proper pan size. Always use cookware appropriate for the
