The recall bulletin is dated March, 1975.
Number: 75 Special Issue
Group: 24 Miscellaneous
Subject: Type II Suburban Furnaces, 22,000 BTU and 30,000 BTU
Models: Certain 1973 and 1974 ZE05000 Motor Homes

"Suburban Manufacturing Company has determined that a defect which related
to motor vehicle safety exists in some Dynatrail model NT-22 and Model NT-32
furnaces that were manufactured between Jan 4, 1973 and August 31, 1973.
The serial numbers of the involved furnaces range between 0282292 and
0364780. Included within these serial numbers are furnace models not
included in the recall."

"The defect involves corrosion stress cracks which can develop in both the
3/8" brass machined flare nut downstream of the furnace inlet, and in the
3/8" brass machined compression nut ahead of the main burner. Such a
condition can, in the extreme, permit a combustible gas mixture to
accumulate in the vehicle."

"Suburban Manufacturing Company has initiated this recall campaign with
respect to the furnaces and GMC Truck and Coach has provided them with the
owner names and addresses of the vehicles involved. Fittings and related
gas lines must be replaced on all affected vehicles."

If anyone would like a copy of the bulletin, you can send me your fax number
or snail mail address off-net.

My 77 has a DouTherm.
