System Piping
Important…
INSTALLATION MUST BE PERFORMED BY A TECHNICALLY
QUALIFIED SERVICEMEN.
TRIO COMMERCIAL BOILERS HAVE A MAXIMUM OPERATING PRESSURE OF 58PSI
NOTE: If normal operating pressures are greater than 30psi please contact the manufacturer for required
trim.
Pipes that are connected to boiler fittings must be supported and placed so that they do not create stresses on
the boiler fittings themselves.
The Trio boiler is a highly efficient boiler in which care must be taken to ensure that high volumes of low
temperature water are not introduced into the boiler. Operating at return water temperatures below 130
º
F
for extended periods of time will allow for the accumulation of condensation, scale and increased soot
formation in the boiler. Corrosion and eventual heat exchanger failure will result.
Low water cut off
A low water cutoff integral to the Hydrolevel 3250 fuel smart hydrostat has been provided with the boiler
package. See boiler trim piping
for the recommended location. Always follow the manufacturer’s
recommendations for installation.
Relief Valves
Relief valves are to be properly piped in to conform to code standards. Discharge piping from the relief
valve must be sufficiently supported so as to avoid strain on the safety valve body.
Discharge piping should terminate 6” above the floor to eliminate damage to the structure or personal injury.
It should be piped to a location where it can be inspected for any visible signs of leakage. It must not be
piped to a point where freezing may occur.
Jacket Installation
The boiler jacket is designed so that all piping connections can be made before the Jacket is installed.

Warning:
The discharge of the pressure relief or safety valve must be piped close to the
floor to prevent scalding in the event of a discharge. The discharge piping must be sized the
same as the valve outlet. Never install any valve between the boiler and the safety valve or in the
discharge piping. Failure to comply with this warning can result in an explosion causing property
damage, severe personal injury, or death.
