INSPECTION OF WINNTEC MODEL #6020 LP REGULATOR

1. Only the Winntec Model #6020 – Dual Stage Double Cylinder – Automatic Changeover Regulator with Pigtails is affected. Replace the regulator and pigtails if the manufacturing date code stamped into the regulator is 2018 or 2019. Example shown below.

2. File a claim for inspection only if the unit does not have a Winntec model #6020 LP regulator or if the date code stamped into the regulator is not 18 XX, or 19 XX. Only replace regulators with date codes 18 XX and 19 XX.

 

REPLACING THE WINNTEC MODEL #6020 LP REGULATOR

1. Close the LP bottles and unscrew the pigtails from the LP bottles.

2. Remove the regulator from the unit.

3. Attach the new regulator to the unit.

4. Connect pigtails to LP bottles.

5. Check fittings, regulator, and connections using approved LP leak detection methods.

6. Proceed with a Drop Pressure Test:

a. Insert manometer into LP system.

b. Turn on both LP tanks.

c. Turn off both LP tanks.

d. Bleed system down to 8” water column.

e. System must hold 8” water column for a minimum of 3 minutes.

7. Ensure system operating pressure is at 11” (+-0.5) water column with 50% load and lockout pressure does not exceed 14” water column.

 


11/4/20–Grand Design RV informs THOR Ind. of three incidents involving Winntec Model 6020 regulators, where the regulators were suspected as the cause of fires. The Thor companies reviewed the issue internally and found no issues with these regulators at that time.

 

12/4/20–KZ RV informs THOR Ind. of two issues under investigation with the same suspect regulators.

 

12/22/20–Grand Design performs lab analysis on two failed regulators and finds they contain an oily substance inside. There is a belief that the oily substance is machining oil from a manufacturing process.

 

2/24/21–Grand Design informs THOR Ind. they are investigating several more fires, and will be sending regulators from those incidents for lab inspection.

 

3/16/21–Lab analysis performed on six regulators from Grand Design, including one exemplar and one from KZ RV. In the lab setting, the KZ RV regulator operated within allowable parameters, although it contained the same oily residue seen on the field samples.

 

4/19/21–THOR Ind. engages Exponent Engineering to conduct analysis of regulators to determine source of oily substance.

 

5/10/21–Safety Committee Meetings conducted at KZ RV, Keystone RV and Jayco RV, to update them on regulator investigation. All committees request further investigation of specific claims and confirmation of Exponent findings.

 

5/12/21–Exponent provides written report/presentation on regulator analysis.

 

5/14/21–Meeting held with Grand Design, Dehco, Winnspec International, and Chen Fong to discuss regulator issue. Winnspec given until May 18, to return information regarding issues with their regulators.

 

5/19/21–Safety Committee Meetings conducted at KZ RV, Keystone RV and Jayco RV to update them on the regulator investigation.

 

5/21/21–THOR Ind. Discussed regulator issue with the Medium Heavy Duty ODI office.

 

5/24/21 & 5/25/21 – Meeting with Grand Design, Dehco, Winnspec International, and Chen Fong at Livonia, MI testing facility, to discuss regulator investigation. Chen Fong agrees the regulator is allowing higher pressure than expected with a compromised second stage seal.

 

5/27/21–Safety Committee Meetings conducted at KZ RV, Keystone RV and Jayco RV.  All safety committees decide to move forward with a recall for safety for units built with a defective Winntec Model 6020 regulator.
