Recall Remedy – Manifold Bolt and Valve Seal  Replacement

1. Remove the knob on the center burner of the cooktop.
2. Look for an orange sticker on the bracket behind the knob.
   1. If there is an orange sticker, then your cooktop has already had the recall remedy installed. Place the knob back on the center burner and you are done.
   2. If there is not an orange sticker, then proceed with the next step of the recall remedy qualification.

 

3.2 Lift the Cooktop

The model and serial numbers, that determine whether your cooktop is part of the recall campaign, are located on a nameplate on the underside of the cooktop.

2 Remove the Cooktop Screws

1. Using a square bit driver, remove the two screws securing the cooktop brackets. Retain the screws for reassembly.

3 Remove the Cooktop

2. Remove the grate.

4 Replacement

This section describes how to replace the manifold bolts and valve seals in the cooktop.

 

4.1 Remove the Manifold Pipe

5 Remove the Manifold Pipe

The manifold pipe must be lowered to access the valves.

1. Using a socket wrench, remove the four manifold bolts.
2. Lower the manifold pipe from the burner valves.

 

4.2 Replace the Valve Seals

6 Replace the Valve Seal

1. For each burner valve, replace the black valve seal with a red valve seal (provided). Do not replace the black seal for the oven thermostat valve.
2. For the burner valves, make sure the tab on the red valve seal sets in the recess in the valve.
3. Dispose of the removed black valve seals and manifold bolts according to “Disposal” on page 5.

 

4.3 Reassemble the Manifold Pipe

7 Install the Bell Washers

1. Place a bell washer (provided) over each of the four threadlocker bolts (provided). Make sure the bell washer is placed in the correct orientation as shown in Figure 7.
2. Assemble the manifold bracket to each valve while turning the threadlocker bolts finger tight.
3. Torque each threadlocker bolt to 15–20 in-lbs with a torque wrench.

Exceeding recommended torque could damage components and cause a possible gas leak.

 

5 Perform a Leak Test

Before reassembling the cooktop, perform a leak test.

1. Turn on the gas supply.
2. Pressurize the range with propane at 11 inches water column.
3. Spray the manifold around the replaced seals with a mixture of soap and water.
4. Ensure there are no bubbles. Observe for a minimum of 1 minute.
5. Reduce the pressure to 8 inches water column and isolate the range and pressure gauge from the supply.
6. Observe the pressure for 3 minutes and ensure there is zero drop in pressure.

 

6 Reassemble the Cooktop

1. Lower the cooktop to the base and push to slide into place.
2. Secure the cooktop brackets with the two original screws.
3. Replace the grate.

 

The installer of this recall remedy kit is required to complete the recall response card (provided):

 

8 Place Recall Sticker

4. If this recall remedy was performed on a compatible unit in an RV, then:
   1. Place an orange sticker (provided) on the bracket behind the center burner knob.
   2. Place the knob on the center burner.
5. If this recall remedy was performed on a compatible unit that is still in its original packaging from Dometic, then:
   1. Attach the second orange sticker to the label on the outside of the box near the unit model and serial number.
   2. Otherwise, dispose of the second sticker.

 

7 Fill Out the Recall Response Card

Under certain conditions during the cooking stove operation, the piezo ignitor can ignite the propane gas leading to an increased risk of personal injury, and/or fire.

 

What we will do

The remedy is is remove the existing manifold bolts and seals and install new seals and bolts. The service and parts required for this corrective action will be provided at no charge to you.

 

What we need you to do

As soon as possible, please make an appointment to have your RV serviced by your dealership. The labor time to perform this correction is approximately 1 hour. Please ask your dealer if you wish to know how much additional time will be needed to schedule and process your RV for this repair.
