Owner's Manual
Cleanout and maintenance
Grease duct is required by NFPA 96 and many local building codes to be inspected and cleaned (if necessary) at specific intervals. VIP+ Grease
Duct must be inspected and cleaned in accordance with local requirements. It requires no additional internal maintenance. *Canadian regulation
requires that an access opening shall be provided on each section of horizontal duct for duct cleaning. The access opening shall be minimum 505
mm (20") by 505 mm(20"). Where the duct size is such that the opening is not possible, openings large enough to permit thorough cleaning shall be
provided at least every 3.7 m (12ft).
ICC recommends that grease containers connected to drainage points be emptied and washed out daily or more often, if necessary. If needed, the
drain nipples should be checked and cleaned whenever the containers are emptied.
Where the duct is installed outside the building, the Galvalume steel outer casing must be primed and painted. The paint surface should be
maintained regularly to prevent possible deterioration of the casing surface. The use of stainless steel outer casing negates the need for painting.
Creosote and Soot – Formation and Need for Removal (For pizza oven and other solid fuel cooking devices)
When wood is burned slowly, it produces tar and organic vapors which combines with expelled moisture to form creosote. The creosote vapors
condense in the relatively cool grease duct of a slow burning fire. As a result, creosote residue accumulates on the duct. If ignited, this creosote
makes an extremely hot fire. For this reason, the duct should be inspected at least once every two months to determine if a creosote or soot buildup
has occurred. Consult local code and officials as they might require more frequent intervals. If creosote or soot has accumulated, it should be
removed to reduce risk of fire.
A licensed or qualified grease duct cleaner should be contacted to clean the duct. Contact local building or fire officials about restrictions and
installation inspection in your area. Adequate clearance is required around cleanouts to assure accessibility for removal of caps and products
accumulated within the grease duct.
Access Door Section
The Access door section (
Figure 42
and
Figure 43
) is installed in line with
the pipe to provide an inspection and
cleaning access point. It doesn't
require specific tools since the
access panels (both outside casing
and flue) are secured with thumb
screws. The Access Door section
comes pre-assembled from the
factory.
The flue panels can be accessed
after removal of the outside casing
door and insulation pad (for insulated
Grease Ducts). To remove the
outside panel, unscrew and remove
all the thumb screws.
The inside access door is made of 2
panels. The outside flue panel is
screwed into a smaller panel that fits
inside the flue. To remove, unscrew
all thumb screws. The 2 bottom
middle screws can be loosen but
can't be removed. This allows the 2
plates to remain joined together but
gives enough clearance to pull the
inside panel out of the flue opening.
The Access Door is attached and
sealed to other pipe sections in the
same manner as described in
Chimney Joint Connection
Section.
