Gas appliance technology center test methods investigations: Direct vent gas fireplaces. Topical report, September 1991-January 1993

OSTI ID:5168391
Two issues in regards to direct vent gas fireplaces are addressed: (1) Reported field incidents of explosive breakage of glass panels of direct vent gas fireplaces were evaluated. It was determined that the incorporation of a simulated explosion test in the ANSI appliance certification standards would be appropriate. Significant design differences between the direct vent gas fireplaces and other direct vent gas appliances are discussed; (2) Potential for accelerated corrosion of vent systems due to low temperature combustion air in the outer annulus of coaxial combustion air/vent systems. The potential for corrosion of the vent wall, as evidenced by length of time the vent wall was set during startup, was found to have an inverse relationship to the combustion air temperature.
