FTV I&O Manual

FTV boilers are factory set to operate with Natural Gas;
BEFORE OPERATING
WITH PROPANE
, the boiler must be converted using the appropriate
Natural Gas to
LP Conversion Kit
; see below. Failure to properly convert the unit to safely operate with
Propane will cause dangerous burner operation, resulting in property damage, serious
injury or death.
ATTENTION: LIQUEFIED PETROLEUM (LP) PROPANE
Liquefied Petroleum (LP) propane gas is heavier than air; therefore, it is imperative that your FTV boiler is not
installed in a pit or similar location that will permit heavier than air gas to collect. Local Codes may require
boilers fueled with LP gas be provided with an approved means of removing unburned gases from the room.
Check your local codes for this requirement.

Exhaust Vent / Air-Inlet Piping
The FTV is certified as a “Category IV” boiler, and require a “Special Venting System”
designed for pressurized venting. The exhaust gases must be piped directly to the
outdoors using the vent materials and rules outlined in these instructions. Failure to
follow these instructions will result in serious injury or death.
