Frequently Asked Hood Questions

1. The hood lights burn out often.
  Excessive vibration will cause standard incandescent bulbs to fail early. Replace with rough service bulbs. Another cause is poor contact with the brass tab in the bottom of the light socket. This will cause the bulb to overheat at the point of contact. This is usually a small amount of solder at the base of the bulb. This solder may melt allowing air to enter the bulb. Once air replaces the inert gas in the bulb the tungsten element oxidizes and the bulb fails. You can tell this has happened by the smoky grey deposits inside the bulb Adjust the tab in the light socket so that it is about 1/4" above the bottom of the socket. Loose wires in the light socket may also result in bulb failure.

2. The stainless is rusting.
  Stainless steel doesn't rust under normal conditions. Stainless gets its non corrosive properties from the chromium in the alloy. The chromium atoms form a passive surface film over the base steel very much like the paint protects your car. Once this layer is removed the base metal is exposed to the moisture in the atmosphere and rust forms. Chlorine in any form combines with the chromium and removes this protective layer and exposes the base metal and rust will occur. NEVER use any chemicals that contain chlorine near any stainless. This includes any cleaners, acids to clean quarry tile or brick, and some detergents. Even the vapors can attack stainless steel. Never use steel wool to clean stainless. Particles of the steel wool will get trapped in the grain of the stainless and these steel particles will rust.

3. The grease doesn't drain into the collection cup.
  There could be something in the grease trough that is preventing the grease from draining. Remove filters and check the trough. Grease troughs should be cleaned frequently to remove any solid sediment that accumulates restricting the flow of grease.

4. Water is collecting in the light fixtures.
  This water is entering the fixture from above. The glass globe is gasketed and if it is on tight water cannot enter from below. The probable cause of this is the duct is leaking. Look at the top of the hood above the ceiling and if you see puddles of water and grease on top of the hood, the duct has a leak. If the duct in not insulated you will probably see some areas, especially in the corners, that look wet.

5. How do I clean the hood?
  Only use mild detergents to clean stainless. DO NOT use any cleaner with chlorine. Use a soft rag. DO NOT use any abrasive pads or steel wool.

6. How often should I clean the filters?
  Filters should be cleaned daily. Clogged filters don't work efficiently and are more difficult to clean. Keeping them clean makes cleaning easier and prevents the build-up of caked on grease and eliminates a potential fire hazard.

7. Grease is leaking outside the hood or collecting in the light fixtures.
  There is probably a leak in the duct allowing grease to collect on top of the hood and it is draining into the fixtures. Check the top of the hood above the ceiling. Any puddles of grease or water indicate there is a leak in the duct.

8. Is ETL the same as UL?
  Yes, both are Nationally Recognized Testing Laboratories that test, certify and inspect products for safety and performance for manufacturers. The standard to which our hoods are tested is UL 710, Exhaust fans are tested to UL Standards UL 762 & UL 705 . You can visit this link for a comparison.

9. What type or replacements bulbs do I need to use?
  • Incandescent light bulbs: 100 Watts max, clear bulb (not frosted)
  • 3' Fluorescent: F25T8, 25 Watts, T-8 Ballast
  • 4' Fluorescent: F32T8, 32 Watts, T-8 Ballast
  • Compact Fluorescent:
    • Lamp type: Compact Fluorescent - Self-Ballasted
    • Bulb: T3
    • Base: Medium Screw (E26)
    • ENERGY STAR® Qualified: Yes
    • Wattage: 26

10. My filters won't come out of my hood, how do I remove the filters?
A. My hood only has 2 filters.
    First lift one filter in the track and moving it toward the back of the grease plenum rest it in the trough with the top leaning o the back of the grease plenum, filter should be standing near vertical and away from filter track. Next side remaining filter over and remove this filter as normal, then reach into plenum and remove the first filter.
B. My hood is a Self Cleaning style hood
    Consult your hood manual to locate the “key” filter, Self cleaning hoods have drip blanks installed on all but one filter to prevent water dripping between the filters. The filter without drip blanks should be removed first (the same filter should be replaced last)
C. Neither A or B describe my hood.
