NTI Matrix Installation And Operation Instructions Manual page 4

Matrix
ATTENTION: LIQUEFIED PETROLEUM (LP) PROPANE
The Matrix 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 Matrix 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.
Model Number

Boiler Vent / Air-Inlet Piping
The Matrix 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.
