1.12 The Condensate Trap

The Brute LX is a high efciency condensating unit. It

requires that the included condensate trap be installed

along with a proper drain.

We recommend that the condensate trap for the wall

mounted Brute LX be installed before mounting it the

wall. For instructions on how to do this, see Figure 10,

Figure 11 and Figure 12 in Section 6 in this manual.

____________________________________________

NOTE: It is easier to install the Condensate Trap to the

Wall Mounted Brute LX before it is mounted to the wall.

1.13 The Pressure Relief Valve (PRV)

The Pressure Relief Valve on the wall mounted unit

must be installed as the rst piping component.

See Section 6.9 'Piping Schematics'

The goal of the control is to operate at a minimum firing rate to match the load on the appliance. 8.7 Pump Control The boiler pump is active anytime there is a call for heat applied to the control.
