In Duct Mounting
When laying out the duct, allow enough length downstream of
the burner to avoid flame impingement; see page 2 of Data 135
for flame lenghts.
Provide at least 3” (76 mm) clearance between the burner and
the top, bottom and sides of the duct.
Profile plates are not required for good burner operation, but
uniform velocity must be maintained for the full length of the
burner. If velocity is not uniform, profile plates can be used to
correct this condition.
Caution
Profile plates should be positioned flush with the firing
end of the burner. If necessary, the plates can be located
up to 1/2” back from the firing end, but under no
circumstances should they be in front of the burner.
BURNER MOUNTING
(CONTINUED)
c
Slot Firing
Firing end of the burner must extend into the duct.
Continuous Mounting (Sealed Firing)
Provide an opening in the duct 1/2” (12mm) larger than the
external burner dimensions. (1/4” (6mm) gap on all 4 sides.)
Customer must supply a suitable gasket between the mounting
flange and the duct wall.
If insulation is 1” (25mm) or greater in thickness, it must be
beveled away from the left and right end plates at approximately
45°.
Burner Piping
The burner is factory assembled and shipped as ordered.
Note:
If it is necessary to redirect piping, the burner may be
inverted. Burner, fuel control BV and blower are not
position concious. All other items i.e. valves, switches
actuators etc. must be installed in accordance with
manufacturers requirements.
