a-Burners
All units use an inshot burner (see figures 10 and 11). A
flame retention ring located in the burner end is used to
keep flame from lifting off the burner. The flame is aimed at
a round flame spreader located in the combustion cham
ber. The spreader distributes the flame evenly around the
circumference of the heat exchanger. Burners in 50,000
and 75,000 Btuh heat exchangers use a separate nonad
justable endcap (see figure 10). Burners in 100,000 and
125,00 Btuh heat exchangers do not use an endcap (see
figure 11).

b-Orifice
All GCS16 units use an orifice which is precisely matched
to the burner input. The burner is supported by the orifice
and will easily slide off for service.
Each orifice and burner are sized specifically to the unit.
Refer to Lennox Repair Parts Listing for correct sizing in
formation.
3-Burner Enclosure
The following units are equipped with a burner enclosure
surrounding the burner assembly:
GCS16R-510-125, GCS16-510-125,
GCS16R-650-125, GCS16-650-125,
GCS16R-411-100, & GCS16H-311-75.
The enclosure is used to reduce sound levels in the burner
area. The enclosure consists of a metal wrapper sur
rounding the burner assembly and a glass flame viewing
window (see figure 12).
The burner can be inspected and the spark/sensor elec
trode removed by removing the burner enclosure sight
glass plate. If the burner must be removed or the orifice
accessed, the burner enclosure must be removed. Burner
enclosure and burner removal is detailed in the mainte
nance section of this manual.
Units equipped with burner enclosure are also equipped
with flame rollout switch. The switch provides unit protec
tion by shutting down the unit when flame rollout is sensed.
