Exhaust Vent / Air-Inlet Piping - NTI VM110 Installation And Operation Instructions Manual

│
Introduction
Failure to use the appropriate Natural to LP Conversion Kit and Orifice when operating
the Vmax boiler 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
number.
ATTENTION: LIQUEFIED PETROLEUM (LP) PROPANE
The Vmax boiler 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 Vmax 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 Vmax VM110 and VM110P are 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.
