VENTILATION
WARNING
Improper ventilation can result in personal injury or death. Ventilation which fails to properly remove flue products
can cause headaches, drowsiness, nausea, or could result in death.
The flue vent, located at the top of the unit, must not be blocked or covered at any time.
All gas appliances must be installed in such a manner that the flow of combustion and ventilation air is not
obstructed. Provisions for adequate air supply must be provided.
NOTICE
Proper ventilation is the owner’s responsibility. Any problem due to improper ventilation will not be covered by the
warranty.
Do not obstruct the front of the cheese melter since combustion air enters through this area. Be sure to inspect
and clean the ventilation system according to the ventilation equipment manufacturer’s instructions.
Canopies are set over ranges, ovens, etc., for ventilation purposes. It is recommended that a canopy extend 6" past
the appliance and the bottom edge be located 78" above the floor. Filters should be installed at an angle of 45° or
more from the horizontal. This position prevents dripping grease and facilitates collecting the run-off grease in a drip
pan, usually installed with a filter.
A strong exhaust fan tends to create a vacuum in the room and may interfere with burner performance or may
extinguish pilot flames. Fresh air openings approximately equal to the fan area will relieve such a vacuum.
The exhaust fan should be installed at least 2" above the vent opening at the top of the cheese melter.
If the cheese melter is connected directly to an outside flue, a CSA design-certified down draft diverter must be
installed.
In case of unsatisfactory performance on any gas appliance, check the appliance with the exhaust fan in the OFF
position. Do this only long enough to check equipment performance. Then turn the exhaust fan back on and let it run
to remove any exhaust that may have accumulated during the test.
GAS REQUIREMENTS
The cheese melter is design-certified for operation on natural gas or propane. The cheese melter is shipped
configured and adjusted for the type of gas specified by the purchaser, which is indicated on the serial plate (see
Figure 1 on page 3). Connect the cheese melter ONLY to the type of gas for which it is configured and adjusted.
