GB300 BOILER INSTALLATION AND OPERATION INSTRUCTIONS

Install the supplied 1/8" stainless steel bleed line on continuous pilot boilers equipped with V88A gas valves. The bleed line must be located in a fixed position relative to the pilot burner and allowing for the escaping gases to be readily ignited by the pilot. Use the supplied fasteners to connect the bleed line to the valve bleed orifice and to the pilot-mounting bracket on the burner tube. Intermittent pilot boilers must vent the V88A bleed orifice to atmosphere external to the building. The bleed line and provisions to locate the line are supplied by the customer. The bleed line on intermittent boilers does not need to be stainless. Aluminum tubing is recommended, but all installations must follow local laws and codes. The burning vent gas must not in any way affect the pilot flame sensor on the pilot burner.

Follow all applicable local codes.

Install the burner tubes by sliding the flattened ends through the slots in the rear panel, Figure 62.

Pull the tubes forward over the brass orifices in the manifold engaging the notch in the flattened part of the burners with rear panel, Figures 63 and 64.

Table 3 has the proper location for the burner tube with pilot assembly(s).
