GE APPLIANCES ZGU366 Propane Conversion Instructions

GE APPLIANCES ZGU366 Propane Conversion

WARNING: Explosion Hazard

Death or serious injury can result from failure to follow these instructions.

• Service by a qualified service technician only.
• Shut off the gas supply and disconnect power before servicing.
• Reconnect all grounding devices after service.
• Replace all parts and panels before operating

The pressure regulator and the burner orifices are set for natural gas. To use propane gas, the regulator and burner orifices must be converted. The orifices must be replaced for propane.

WARNING: Do not operate the cooktop or oven burners of this range when using propane (bottled) gas before converting the pressure regulator and burner orifices for propane gas use. Failure to do so could cause high flames and toxic fumes which can result in serious injury.

The propane orifices for the cooktop burners are shipped on the back of the range in the location shown.

TOOLS REQUIRED

• Adjustable wrench
• Socket wrench with 1/2″ socket and extension
• Phillips head screwdriver
• Flat-bladed screwdriver (blade approximately 3/32″ across)
• Nut drivers: 1/4″, 9/32″ or 7mm
• 7mm open-end wrench
• Phillips screwdriver
• Large flat blade screwdriver

To adjust your range for use with propane gas, follow these instructions:

1. Disconnect all electrical power, at the main circuit breaker or fuse box.
2. Shut off the gas supply to the range by closing the manual shut-off valve.

CONVERTING THE PRESSURE REGULATOR

NOTE: Location varies by model.

If gas is detected at the regulator use a liquid leak detector to verify the location.

NOTE: 48″ All Gas ranges have two regulators. All other ranges only have one regulator.

Cooktop Regulator

1. Use a large flat blade screwdriver to remove the cap from the pressure regulator.
2. Turn the brass cap over for propane gas and reinstall into the regulator.

CONVERTING THE COOKTOP BURNERS

• Remove the top grates, burner caps, and burner heads.
• Use a 7 mm or 9/32″ nut driver for the Dual Stack burner, or a 7mm or 9/32″ open end wrench (only for Multi-ring) to remove the top burner orifices. These may be accessed through the burner opening in the base. The Multi-Ring orifice is accessed by removing the orifice cover using a Phillips screwdriver.

NOTICE: Save these orifices for future conversion back to natural gas.

• Remove the propane orifices from the bag provided.

• Install the propane orifices in their precise locations. To prevent leakage, make sure the orifice spuds are securely hand tightened into the gas supply tubes. The orifice cover must be reinstalled.
• Install the old orifice spuds into the bag along with these instructions, and replace onto the back of the range for possible future conversion.

CONVERT GRIDDLE ORIFICE

Locate the 3/4″ long griddle orifice. Select the proper orifice size for your gas and burner from the conversion chart.

• Lift off the griddle flue cover. Remove the 2 inside clamping screws.

NOTE: Remove the 2 screws positioned on the inside only. Do not remove the outermost screws they are for leveling.

• Lift out the cast-iron grease trough. Remove by sliding the griddle toward the rear and out of the hold-down tabs along the bottom.
• Remove the 4 screws on the capillary bracket and set the bracket and capillary aside.
• Remove the 2 hold-down screws at the rear of the burner. Pull the burner straight back toward the rear and out of the gas inlet.
• Use a 1/2″ deep well socket to remove and replace the orifice.
• Reverse these steps to reassemble the griddle. Push excess capillary back into the entry hole. Place the unused orifice in the holder for possible future use.

CHECK SURFACE BURNERS

Push and turn a knob to the LITE position. A clicking sound indicates the proper operation of the ignition system. When lighting any burner, sparks will appear at all burners but gas flows from only the one selected. Once the air is purged from the supply line, the burner should light within 4 seconds. After burner lights, rotate the knob out of the LITE position. Try each burner in Succession until all burners have been checked.

Quality of Flames

• Determine the quality of flames visually. Normal burner flames should look like (A) or (B).
• Long, bright yellow flames are not normal.
• Normal flames may show signs of an orange tint when well heated or signs of flickering orange due to particles in the gas or air.

ADJUSTING THE LOW FLAME SETTING ON COOKTOP BURNERS

Low setting adjustments must be made with other burners in operation on a medium setting. This procedure prevents the low flame from being set too low, resulting in the flame being extinguished when other burners are turned on.

• Turn on all surface burners to medium setting.
• Multi-Ring Burners -Outer Ring and Inner Ring

1. Rotate the knob to the MED setting.
2. Remove the knob and insert a small flat blade screwdriver into the valve shaft and turn clockwise to tighten down the bypass set screw. Hold the outer shaft while turning the inner screw.
3. The OUTER RING flames should be adjusted so that they barely curl over the top edge of the burner cap as shown.
4. If the flame appears too low or unstable, slowly turn the bypass screw counterclockwise until a stable flame exists for each burner. Remember, another burner must be turned on to MED.
5. To further test the OUTER RING flame, set the burner to MED for at least 4 seconds, then turn to HI. If the flames turn yelloW, slowly increase the OUTER RING flame by turning the OUTER RING by-pass screw slightly counterclockwise and check again.
6. Replace the knob and rotate the knob to the LO setting.
7. Remove the knob AND the right side bezel screw as shown.
8. The INNER RING flames should be adjusted by inserting a small flat blade screwdriver into the bezel screw hole and turning clockwise to tighten down the bypass set screw with the knob at the LO setting. Locate the screw through the hole with a flashlight if necessary.
9. If the flame appears too low or unstable, slowly turn the bypass screw counterclockwise until a stable flame exists for each burner. Remember, another burner must be turned on to MED. When adjusting, make sure the low flame is contacting the ignitor and the burner head is grounded properly or the spark module will continue to attempt to reignite the flame.
10. Reinstall the right side bezel screw, Do not over-tighten, and Replace the knob.

C. Dual-Flame Stacked Burners: Upper Flames

1. Rotate the knob to the MED setting.
2. Remove the knob.
3. The upper ring of flames should be adjusted with the knob at the MED setting by adjusting the set screw in the center valve shaft. Hold the outer shaft while turning the inner screw. The flames should be adjusted so that they barely Curl over the top edge of the burner cap.
4. Replace the knob.

• Additionally quickly open the door while observing flame. If the flame is extinguished, continue adjusting the set screw for a larger flame. Repeat door openings until the flame are stable.

SPECIAL NOTE: To convert the oven back to natural gas, reverse the instructions given in making propane adjustments. Save these orifices for future conversion back to natural gas.
