User Responsibilities
This appliance must be installed and serviced by a qualified installer or service technician. This appliance must be serviced and
inspected annually when operating in normal residential applications. Demanding applications or extreme conditions (i.e.
commercial) may require more frequent service and inspection. As the User/Owner of this equipment, you are responsible for
ensuring the maintenance is performed at the required intervals. It is also the Users responsibility to ensure the Vent and
Combustion-Air Intake termination is kept clear of ice and snow or any other obstruction. Failure to follow these instructions
could result in fire, serious injury, or death.
Failure to have the appliance properly serviced and inspected on a regular basis may result in property

Failure to keep the Vent and Combustion Air Intake clear of ice, snow, and other debris may result in
property damage, serious injury, or death.
Installer Responsibilities
As the installing technician it is your responsibility to ensure the installation is performed in accordance with this instruction
manual as well as any applicable local or National installation codes. It is also your responsibility to inform the User/Owner of
their obligation with respect to the above description under “User Responsibilities”. Failure to follow this warning could result in

ATTENTION: LIQUEFIED PETROLEUM (LP) PROPANE
The Trinity Ti is factory set to operate with Natural Gas. BEFORE OPERATING WITH PROPANE, the specified LP
Conversion Kit must be installed to convert the appliance so it will operate safely with LP Propane. Listed below is the
correct Natural to LP Propane Conversion Kit number for Trinity Ti100-200 boiler models. Note: kit number 82650-1
contains two LP conversion orifices. The smaller orifice, labeled 34, must be used in the Ti100, while the larger orifice,
labeled 52, must be used in the Ti150 and Ti200.
Liquefied Petroleum (LP) propane gas is heavier than air; therefore, it is imperative that your Trinity Ti boiler is not
installed in a pit or similar location that will permit heavier than air gas to collect. Local Codes may require appliances
fueled with LP gas be provided with an approved means of removing unburned gases from the room. Check your local
codes for this requirement.
