BOILER PIPING
Boiler Water
Pressure - Triton boilers are intended to solely for use in pressurized closed-loop heating systems operating with
a "fill pressure" between 12-15 psi at the boiler outlet and a Relief Valve pressure of 30 psi (maximum
working pressure of the boiler).
Oxygen Elimination - The Triton boiler is designed to operate in a pressurized closed-loop heating system, free
of air and other impurities. To avoid the presence of oxygen, ensure all of the air is removed from the system
during commissioning via strategically placed, adequately sized air-removal devices located throughout the
heating system and the boiler piping (Figure 6-1). Immediately repair any leaks in the system plumbing to
avoid the addition of make-up water; make-up water provides a source of oxygen and minerals that may lead
to heat exchanger failure, poor performance, unnecessary wear of system components, and premature failure.
The Triton is not approved for operation in an "open system", thus it cannot be used for
direct potable water heating or process heating of any kind.
Antifreeze - If using antifreeze, use an inhibited propylene glycol specifically designed for hydronic
systems.
Near Boiler Plumbing
Install boiler piping for central heat and domestic hot water as shown in Figure 6-1.
Gauges – The temperature and pressure gauges (Tridicator) is factory supplied and must be field installed in the
front of the boiler or on the coil plate.
Relief Valve – A 30 psi relief valve is factory supplied and must be field installed.
Piping – The closed loop piping system must be in accordance with the central heat piping illustration. All piping
joints must be secure and water tight or the boiler warranty is void.
Water Supply - Pressure regulating "fill valve" (12-15 psi) and back flow preventer are required (Figure 6-1).
Boiler Venting - Hot waters boilers are designed to operate with the airless water in the system. The NY Thermal
boilers are designed with a built-in air trap, to purge air at the ¾" relief valve nipple. An air vent must be
installed here or the boiler warranty is void.
Low Water Cut Off (LWCO) – The HydroStat 3250, when installed in a Triton boiler,
cannot be used as a LWCO due to it's location in the boiler; therefore, a standard well is
factory supplied with the unit. If a LWCO device is required, an external LWCO must be
field installed to provide protection against firing with low water levels. Failure to follow
these instructions may result in fire, serious injury or death.
Removing Air - Do not fill the boiler with water until you are ready to fire the burner.
Once filled with water, bring the boiler up to temperature and remove the air.
Removing Air from the Boiler:
1. Open automatic air vent 1 turn.
2. Bleed air from system. Starting at the lowest point in the building, open air vents one at a time and leave them
open until water comes out. Close all air vents, except the automatic air vent.
3. Refill to correct pressure, 12-15 psi.
