Gas Conversion Parts
The FT oor standing, condensing boiler is congured
for Natural Gas (NG) from the factory. A 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 2000ft,
check that the “High Altitude” Installer setting has
been adjusted to suit your installation altitude. See
section 4.14.

qualied service agency in accordance with the
manufacturer’s instructions and all applicable codes
and requirements of the authority having jurisdiction.
The information in these instructions must be
followed to minimize the risk of re or explosion or
to prevent property damage, personal injury or death.
The qualied service agency is responsible for the
proper installation of this kit. The installation is not
proper and complete until the operation of the
converted appliance is checked as specied in the
manufacturer’s instructions supplied with the kit.
Installation must conform to local codes and the latest
edition of the National Fuel Gas Code, ANSI Z223.1
and CAN-B149.1. Failure to follow instructions could
result in serious injury or property damage. The
qualied agency performing this work assumes
responsibility for gas conversion.
CAUTION
This 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 the
proper type of gas is supplied to your combination
boiler.
