Burner Tube Through Rear Base Panel; Burner Tubes On Manifold; Burner Tube Locked To Rear Base Panel - Smith Cast Iron Boilers GB300 Installation & Operating Manual

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.
