GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

Make sure that the sections are square with the burner base. Align the bottom front edge of the sections so they’re flush with the face of the burner base front panel, Figure 39. Lift the next section into place being careful not to damage the ceramic blanket or hydronic seals and install the draw rods, washer and nuts.

Use a spirit level to ensure that the first two sections are plumb, Figure 39. Once plumb, open the Flue Collector Box. The box will have a number from 63203 to 63210 on it, Figure 40. Remove the flue baffles and install them as shown in Figure 41. The flue baffles must be inserted so they’re as high in the openings as possible. Once all the flue baffles are installed, evenly torque each washer backed draw rod nut to 30 ft lbs, 42 Nm Figure 42.

WARNING: The flue baffles must be installed as shown in Figures 40 and 41.The flue baffles must not be changed or altered in any way. Failure to comply with this warning can result in excessive levels of carbon monoxide which can result in severe personal injury or death!

Repeat this process for the remaining sections. Once the draw rods have been torqued install the four “J” bolts, washer and nuts from the X1 Box that fasten the heat exchanger to the burner base, Figure 43.
