VENTILATION PREPARATION
/ Ventilation preparation / Specifi cations
This cooktop will best perform when installed with Bertazzoni exhaust hoods. These hoods have been designed to work in conjunction with the Bertazzoni cooktop and have the same fi nish for a perfect look. Before installation of the exhaust hood, consult lo­cal or regional building and installation codes for additional specifi c clearance requirements. Refer to the cooktop hood installation instructions provided by the manufacturer for additional infor­mation.
Select Hood and Blower Models:
• For wall installations, the hood should be equal or larger width than the cooktop. Where space permits, a hood larger than the range may be desirable for improved ventilation performance.
For island installations, the hood width should overhang the cooktop by a minimum of 3” (76 mm) on each side.
Hood Placement:
• For best removal of smoke and odors, the lower edge of the hood should be installed between 25 1/2” (65 cm) and 31 1/2” (80 cm) above the range cooking surface.
If the hood contains any combustible materials (i.e. a wood covering), it must be installed at a minimum of 36” (914 mm) above the cooking surface.
Consider Make-Up Air:
Due to the high volume of ventilation air, a sour­ce of outside replacement air is recommended. This is particularly important for tightly sealed and insulated homes. A qualifi ed heating and ventilating contractor should be consulted.

PRESSURE REGULATOR
Since service pressure may fl uctuate with local demand, every gas cooking appliance must be equipped with a pressure regulator on the inco­ming service line for safe and effi cient operation. The pressure regulator shipped with the applian­ce has two female threads ½” NPT. The regulator shall be installed properly in order to be accessible when the appliance is installed in its fi nal position.
/ Gas connection
Manifold pressure should be checked with a ma­nometer and comply with the values indicated be­low: Natural gas 4.0” iwc LP/Propane 10.0” iwc Incoming line pressure upstream from the regula­tor must be 1” iwc higher than the manifold pres­sure in order to check the regulator. The regulator used on this cooktop can withstand a maximum input pressure of 1/2 PSI (13,8” iwc or 3,5 kPa) If the line pressure exceeds that amount, a stepdown regulator is required. The appliance, its individual shut-off valve, and the pressure regulator must be disconnected from the gas line during any pressure testing of that sy­stem at pressures in excess of 1/2 PSI (13,8” iwc or 3,5 kPa). The individuaL manual shut-off valve must be in the OFF position during any pressure testing of the gas supply piping system at test pressures equal to or less than 1/2 PSI (13,8” iwc or 3,5 kPa).

/ Gas conversion
LP
The conversion is not completed if all 4 steps have not been concluded properly.
Before performing the gas conversion, locate the package containing the replacement nozzle ship­ped with every range.
IMPORTANT: Each nozzle has a number indica­ting its fl ow diameter printed on the body. Consult the table number 1 for matching nozzles to bur­ners. Save the nozzles removed from the rangetop for future use.
Step 1: pressure regulator
The pressure regulator supplied with the applian­ce is a convertible type pressure regulator for use with Natural Gas at a nominal outlet pressure of 4” iwc or LP gas at a nominal outlet pressure of 10”iwc. and it is pre-arranged from the factory to operate with one of these gas/pressure as indica­ted in the labels affi xed on the appliance, package and Instruction booklet. To convert the regulator for use with the other gas: Unscrew by hand the upper cap of the regula­tor, remove the white plastic attachment from the cap, reverse its direction and screw it again fi rm- ly against the cap. The white plastic attachment has arrows indicating the position for natural gas (NAT) and LP gas (LP). Screw by hand the metal cap in the original posi­tion on the regulator.

/ Gas conversion
Step 3: visula checks
Surface burners
The burner fl ame color should be blue with no yel- low on the tips. It is not uncommon to see orange in the ame color; this indicates the burning of airborne impurities in the gas and will disappear with use. With propane (LP) gas, slight yellow tips on the primary icone are normal. The fl ame should burn completely around the bur- ner cap. If it doesn’t, check that the cap is posi­tioned correctly on the base and that the ports are not blocked. The fl ame should be stable with no excessive noi- se or fl uttering.
Step 4: minimum fl ame adjustment
WARNING! These adjustments should be made only for use
of the appliance with natural gas. For use with li­quid propane gas, the choke screw must be fully turned in a clockwise direction.
SURFACE BURNERS Light one burner at a time and set the knob to the MINIMUM position (small fl ame). Remove the knob. The cooktop is equipped with a safety valve. Using a small-size slotted screwdriver, locate the choke valve on the valve body and turn the choke screw to the right or left until the burner fl ame is adjusted to desired minimum. Make sure that the fl ame does not go out when switching quickly from the MAXIMUM to the MINI­MUM position.
For the gas valve of dual burner the choke valve is located on the valve body, the A screw adjust the outer ring, the B screw adjust the inner ring.
yellow fl ames: further adjustment is required
yellow tips on outer cones: normal for LP gas
soft blue fl ames: normal for natural gas
After performing all these visual checks, reinstall the bottom panel of the oven compartment and proceed to setting the minimum for each burner.
