2.2.4 Boiler Connections
Upon delivery, the Modulex Boiler has all the connections on its R.H. side (Figure
2-3). Note that the R.H. orientation is the right hand side when viewed facing the front of the boiler. These
connections include: water supply and return, gas, combustion air intake and flue collector outlet. The
locations of the air intake and/or the flue collector outlet can be changed on site by removing knock-outs on
the boiler right, left or back side panels. To attach the exhaust connector to the flue collector, use the
screws and the gaskets supplied inside the plastic bag and use a cross-tip (Phillips) screwdriver at least 12
in. (300 mm) long.

Boiler Connections
Water supply and return and gas connections can also be moved to the boiler’s L.H. side by inverting the
flow (supply)/return manifold on the left side using the following procedure:
1. Remove the front, side and rear panels from the boiler.
2. For reversal of the water flow (supply) and return manifolds from the R.H. to the L.H. side, remove
the small plates securing the flow (supply) and return global temperature sensors (Figure 2-4).
