The FT Series, fl oor standing, condensing boiler is confi gured
for Natural Gas (NG) from the factory.
A Natural Gas to Propane
Conversion Kit is included with every FT. The gas conversion kit will
show you how to convert your FT boiler to propane gas. If your FT
does not have the bag containing the conversion kit, a replacement kit can be
obtained. Contact the manufacturer and request a replacement conversion kit.
NOTICE
If your installation altitude is greater than 2000 ft, please check that the ‘High Altitude’
Installer Setting has been adjusted to suit your installation altitude.
CAUTION
This combination boiler has already been set to burn natural gas,
but can be converted to burn LP gas. Before placing the combination
boiler into operation, verify that your fuel source is natural gas. Or
verify that your fuel source is propane if you are converting this
combination unit to propane.
