Ts Series Installation and Operation Instructions

Treatment -
Boiler water that falls outside of the conditions listed above must be treated with a corrosion
inhibitor. Each Trinity Ts boiler is provided with a bottle of “Fernox F1” corrosion inhibitor, adequate to treat a
26.4 gallon (100 liter) heating system to a minimum required concentration of 0.5%. Systems with greater
volume will require more inhibitor. For information on performing the treatment, follow the instructions
included with the Fernox F1 Protector. See Table 10-1 for a list of recommended boiler system cleansers and
corrosion inhibitors.
To maintain protection, the level of corrosion inhibitor must be monitored periodically
for the correct concentration.
Anti-freeze
- For systems requiring freeze protection, use only inhibited propylene glycol, specially formulated
for hydronic heating systems; use of other types of antifreeze may be harmful to the system and will void the
warranty. Note: the use of glycol may reduce the usable output capacity of the boiler, thus requiring the unit to
be “down-fired” by limiting the maximum operating capacity and/or the maximum water temperature. NTI
recommends against exceeding 35% concentration of glycol.

Pressure Relief Valve -
A Pressure Relief Valve is factory supplied with each unit. Trinity Ts boilers have a
maximum allowable operating pressure of 160PSI. A pressure relief valve with a higher discharge pressure
rating (up to the MAWP of the boiler) may be used as long as the relieving capacity is in excess of the maximum
input capacity of the boiler.
The pressure relief valve must be installed at the boiler outlet and in the vertical position, as shown in Figure 10-
1, with the drain pipe outlet exiting the side of the pressure relief valve horizontally and elbowing down.
If installed with the incorrect orientation (horizontally with drain pipe out the bottom) the
relief valve may not function properly resulting in property damage or personal injury.
Ensure the discharge of the pressure relief is piped to a location where the steam or water
will not cause property damage or serious injury.
Pressure Gauge –
Trinity Ts units come with a factory supplied Pressure Gauge. The pressure gauge must be
installed at the boiler outlet prior to any circulators and in the vicinity of the pressure relief valve. See Figure 10-
1.
Flow Switch / Low Water Cutoff
– Trinity Ts boilers are not provided with a LWCO or Flow Switch. Check
with your local authorities for the requirements of these devices prior to installing the boiler. If a Flow Switch is
installed it must be located in series with the boiler and in accordance with the instructions provided with the
flow switch. NTI recommends installing the flow switch in a 1”diameter line.
When external safety devices are used, such as a LWCO, Flow Switch, or a Temperature
Limiting Switch, they must be wired as per the instructions provided in this manual.
