Brute Elite Page 13 INSTALLATION STANDARDS MATERIAL UNITED STATES CANADA Stainless Steel UL 1738 Venting must be ULC-S636 certified for use as PVC, sch 40 ANSI/ASTM D178 venting material. The venting material must be chosen CPVC, sch 40 ANSI/ASTM F441 based upon the intended application of the boiler.
B RADFORD W HITE C ORP. Page 14 units unless the vent system meets this requirement. Brute Elite units are never permitted to share a vent with Category I appliances. A condensate drain trap is built into Brute Elite. Connect a 3/4" PVC pipe between the drain connection and a floor drain (or condensate pump if a floor drain is not accessible).
Brute Elite Page 15 1. Figure 12 shows the requirements for mechanical vent terminal clearances for the U.S. and Canada. 2. Vent terminals for condensing appliances or appliances with condensing vents are not permitted to terminate above a public walkway, or over an area where condensate or vapor could create a nuisance or hazard.

B RADFORD W HITE C ORP. Page 40 SECTION 9. Modes of Operation The Brute Elite control allows the boiler to operate in many different modes of operation. The mode must be selected based upon the requirements of the installation. The following sections describe the basic operation of the Brute Elite in each of the different modes.
Brute Elite Page 41 setpoint is used to limit the maximum water temperature leaving the boiler only. The modulation rate is controlled by a 4-20mA (0-10Vdc using converter) signal supplied by an external control.
B RADFORD W HITE C ORP. Page 42 firing rate is controlled by the DHW setpoint temperature and the water temperature at the heat exchanger outlet. Once the DHW call is supplied the control starts the boiler and DHW pumps and begins the ignition process.
Brute Elite Page 43 13. Check gauge for correct water pressure and also check water level in the system. If the height indicated above the boiler insures that water is at the highest point in the circulating loop, then the system is ready for operation.
B RADFORD W HITE C ORP. Page 44 in Table 16 . If the CO 2 is not within the range shown, adjustments may be made. To adjust the low fire CO 2 , locate the low fire adjuster screw according to the appropriate figure. Slowly make adjustments in 1/16 of a revolution increments until the CO 2 is within the range identified.
