Trinity Lx │Installation and Operation Instructions Lx Series
Failure to use the appropriate Natural to LP Conversion Kit and Orifice when operating
the Trinity Lx with Propane will result in extremely dangerous burner operation leading
to property damage, serious injury or death. Refer to section titled ATTENTION:
LIQUEFIED PETROLEUM (LP) PROPANE for applicable conversion kit and LP
orifice numbers.
ATTENTION: LIQUEFIED PETROLEUM (LP) PROPANE
The Trinity Lx is factory set to operate with Natural Gas. BEFORE OPERATING WITH PROPANE, the
specified LP Conversion Kit and Orifice must be installed to convert the boiler so it will operate safely with
LP Propane. The correct kit and LP orifice is listed below (Each kit comes with conversion instructions).
Liquefied Petroleum (LP) propane gas is heavier than air; therefore, it is imperative that your Trinity Lx 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.

Boiler Vent / Air-Inlet Piping
The Trinity Lx is certified as a “Category IV” boiler, and requires 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.
