· Do not loosen or remove the fifth nut directly below the burner flange
· Secure suspension chain to eye hook in order to stabilize burner—angle chain back over
burner 6 to 10 inches to allow for heater expansion.
SERVICE ACCESS: ALLOW A MINIMUM OF 6 INCHES (15 cm) FROM THE ACCESS END OF THE
BURNER AND A MINIMUM OF 24 INCHES (60 cm) FROM EITHER SIDE OF THE BURNER TO A WALL
OR ANY OBSTRUCTION THAT WOULD RESTRICT OR LIMIT ACCESS TO THE BURNER FOR SERVICE
OR REPAIRS. (SEE SECTIONS 5 & 6 - PRE-INSTALLATION SURVEY AND MOUNTING CLEARANCES)

burner
12) Mount the Burner to the first tube flange using the four nuts and bolts provided (FIG 12)
a) Insert two bolts through top holes in burner flange
b) Install gasket onto the two bolts to position it between the burner and tube flanges
c) Align burner and tube flanges and secure the two bolts with nuts
d) Install bottom bolts and nuts and snug to align the two flanges
e) TIGHTEN THE BOLTS IN AN OPPOSITE CORNER SEQUENCE AND ENSURE
THAT THE BURNER IS IN HORIZONTAL ALIGNMENT WITH THE TUBE
13) The ‘center of gravity’ of the burner is slightly off-center that of the tube system.
In order to prevent rotation of the burner:
 Install support chain from the burner eye hook to a point approximately 6 to 10
inches (15 to 25 cm) back over the burner away from the first tube hanger to allow
expansion of the system
 DO NOT fasten chain from the burner eye hook to the first hanger suspension point
 The support chain angled back over the burner will allow “straight back” movement
of the burner when the system heats and expands.
