Goodman furnace & plastic vent safety recall:

This document provides residential heating furnace safety information about the Goodman Furnace Heating Vent Safety High Temperature Plastic Vent HTPV Recall By Goodman Manufacturing, a Houston TX air conditioning and heating firm.

To be clear, Goodman did not itself manufacture the HTPV piping but rather obtained it from other HTPV manufacturers. Nonetheless, the Goodman HTPV vent is a serious safety hazard because it risks release of dangerous, potentially fatal carbon monoxide gas in buildings if this defective furnace vent has not been replaced.

Goodman Plastic Heater Vent HTPV Recall Notice, Contact Information, Details

Goodman plastic heater vents were recalled by the company originally in 1998 and in an updated notice in 2009 (as Plexvent™ or Ultravent™) , because of the possibility of carbon monoxide leakage hazards. Cracks in the flue venting system were reported due to corrosion and cracking. Our literature review indicates that there were about 10,000 Plexvent & Ultravent HTPV flue gas venting systems used to vent combustion products from some Goodman mid-efficiency furnaces that were in turn manufactured between October 1988 & July 1994.

CPSC, Goodman Announce Recall to Replace HTPV Pipes

WASHINGTON, D.C. - Since August 1996, Goodman Manufacturing Company, L.P., of Houston, Texas, in cooperation with the U.S. Consumer Product Safety Commission (CPSC), has been conducting a program to replace high-temperature plastic vent (HTPV) pipe used to vent about 8,000 Goodman mid-efficiency gas furnaces. The HTPV pipe used in these vents could be susceptible to corrosion, cracking and joint separation, which could result in the release of carbon monoxide into living areas, presenting a deadly threat to consumers.

Although Goodman did not manufacture HTPV pipe, some models of Goodman furnaces were vented using HTPV material produced by other companies. Goodman voluntarily undertook its replacement program to help ensure the safety and comfort of its gas-appliance customers and has already replaced many HTPV systems.

For each Goodman furnace that is horizontally vented with HTPV pipe, Goodman will continue to arrange for replacement of the vent with a new, approved vent at no charge. Alternatively at the homeowner's option, Goodman will continue to replace the entire furnace and vent with a brand new, high-efficiency Goodman furnace and suitable vent for only the manufacturer's price for the new furnace itself, with no charge for labor, associated materials or dealer markup.

Owners of Goodman furnaces that are vented with HTPV pipe should contact their local heating contractor for more information or call Goodman at (800) 394-8084.

TECHNICAL NOTES on the Plastic Heating Vent Safety Concern:

Ontario, 1-2 yrs ago, 3 mfgs:

  • Plexvent
  • Celvent (selvent?)
  • Ultravent

Coming apart at cemented joint and also general pipe cracking on plastic vents used on mid-range efficiency gas furnaces and boilers.

They had an 8/96 deadline to replace all units - as the entire unit incl. vent was listed as an entire unit, couldn't just replace the vent so replaced a bunch of entire systems. Thousands done that way.

Class action lawsuit against manufacturers, Ontario New Home Warranty Program, &c

Each manufacturer had to get its unit re-listed, some went to stainless steel vents, most went to a new plastic with an exterior additional induced draft fan so even if cracks inside, flue gases won't leak into the house.

OPINION: some furnace blower fans defeat the furnace's heating efficiency by exhausting heat from the house. Some thoughts that are adding complexity - second fan, but it's probably interlocked so will shut down heat if fan fails.

2/7/97 tc Daniel Friedman with Giddings at CPSC:

  • Flexco, Hardin Cooley, mid efficiency furnaces and boilers,
  • GE Resin - Ultratemp - failed in 2-6 years;
  • AGA certified furnaces and boilers -
  • He estimates in US they are in 350,000 homes - boilers in Northeast and Furnaces in more temperate areas.
  • St first boiler mfgs supplied the vent with the heater
  • Later the material was "specified" but not included with the heater

The Fix for these Plastic Heater Vents:

  • Stainless steel and power vent
  • Ontario first observed the failures - before in US
  • a second-generation - 1993-4 - pipe performed better but has no data to prove it's long term performance is ok - UL has changed its standards. Radel -- is a replacement pipe.

How to Identify the problem Plastic Heating Vents:

  • Plex-vent is marked - the revised mix is Plex-vent-2 - both are black
  • Ultra-vent - see date code on the pipe - gray pipe - new is post 8/93
  • CEL-vent - black pipe - revised mix is Celvent-2

CPSC sees fewer field failures with the new stuff - but no long term data yet. Says the second-generation plastic is no longer specified by the heater mfgs.

  • Chevron Sued GE
  • Consumer class action ongoing in Tennessee

He (Giddings) sent ASHI a letter 9/96 - to Paterkevich - will re-fax to me got a mumbled reply from some unknown ASHI guy

Typical cost to cure defective or unsafe plastic heating vent pipes is $400-$600.

Other information sources on the plastic heater vent safety recall:

  • Carson Dunlop tech notes
  • the CPSC letter to ASHI
  • GAMA - Gas Appliance Mfgs Assoc - or maybe AGA or Dan's reference - Doug DeWerth
  • UL had meetings in June '94 on problems with plastic vent piping and the UL Standard 1738 - what were the pre and post revision standard texts?
  • Don Fugler, at Canadian Meeting Association of CMHC - Research and QA - per Steve Bliss at the Journal of Light Construction?
  • Don Fugler, CMHC Canadian Home Mortgage Corp? - 613-748-2658 in Ottowa - ?? what's this note about

2/8/97 Actions Taken by DF

  • ASHI Reporter article (done)
  • Internet article(done)
  • JLC Article - poss extra exposure in tract homes (done)
  • get info first from varied sources and review my notes with CPSC &C
