INSTALLATION

SL 28-160 MODULATING GAS BOILER

WATER PIPING

1.6.1 General Piping Issues

The SL 28-160 boiler was designed to be easy to install in almost any application. 

Its unique multi-port piping design allows connection from either side or both 

sides at once. 

Primary/secondary piping, or the use of a hydraulic separator is recommended 

for maximum flexibility in multi-load applications, but piping loads in parallel 

is also encouraged in systems that only have two loads, or when loads are 

operating simultaneously. The extremely low pressure drop through the SL Series 

heat exchanger allows many options not available in other designs. In short – 

IBC has built a boiler that will allow you to pipe the system the way you prefer, 

rather than try and dictate your piping practices from boiler to radiator.
There are some important details to consider however, and this section of the 

Installation and Operating Manual will walk you through them so you can enjoy a 

trouble-free installation.
