**This value can vary depending on how the unit is 
operated, and the type and moisture content of the fuel 
used. Figure shown is based on maximum fuel con-
sumption obtained under laboratory conditions and on 
average efficiencies.
***These values are based on operation in building-
code conforming homes under typical winter climate 
conditions. If your home is of nonstandard construction 
(e.g. unusually well insulated, not insulated, built under 
ground, etc.) or if you live in a more severe or more 
temperate climate, these figures may not apply. Since 
so many variables affect performance, consult your Ver-
mont Castings’ Authorized Dealer to determine realistic 
expectations for your home.
