Page 4: Venting
2.1 Location In all cases, the Trinity boiler must be installed indoors, in a dry location, such that the gas components are protected from dripping or spraying water or rain, during operation and servicing. The boiler location ambient temperature is maintained to a minimum of 50°F. Determine the best location of the vent termination, and if possible locate the boiler as close to the termination point as possible. - Page 5 3.2.2 Concentric Vent Termination (No longer approved for Canada) • Ti100-200 Only (Not for use with Ti400) • NTI part number 82666 (York part number 1CT0303) • Instructions included with vent terminal contain more detailed assembly and installation instructions. •...

2. Air for combustion must be drawn from outdoors from an area free of dust and contaminants. Combustion air containing chemicals such as chloride, fluoride, bromine or iodine, will cause corrosion damage of the heat exchanger voiding your NTI warranty. Avoid drawing combustion air from the vicinity of swimming pools, laundry facilities, workshops, or other areas where the air may contain chemicals or dust. - Page 8 Within 6’ of a mechanical air supply inlet to any building, or roof eve containing soffit openings.

The Trinity boiler comes in two versions, Heating and Combi. Heating Version – The standard heating version is designed to operate in a hydronic heating system and can operate with an indirect water heater. Combi Version – This special version is equipped with internal components to provide hydronic heating and domestic hot water heating. See Sections 6.1 and 6.3. - Page 14 • Models Ti100-200 A certified LWCO or Flow Switch is not provided in the package, however one is to be field installed in any application where the boiler is located above the radiation or where local authorities require it. NTI recommends installing a LWCO or flow switch to prevent the boiler from firing without water in the heat exchanger.

Once the room thermostat is satisfied, it breaks power to the TT terminal of the pump controller, which opens the X –X contacts, which opens the T-C circuit. The Pumps and burner turn off. In an injection system, it is important to understand the effect of flow and temperature set points. It may be necessary to program the Sentry controller higher than the desired Mix temperature of the Hottest Loop. - Page 27 8.2 Sentry 2100 Operation The Trinity boiler employs a pneumatic modulation system. This modulation system increases or decreases the velocity of the blower, to meet the demand for heating. The gas valve, senses this change, in blower pressure, and introduces the required amount of gas, to ensure correct combustion.
