NOTE

The 1/8” street elbow shown in Figure 19 was previously removed in step 4(f)
and attached to the 3” nipple on the Low NOx Burner Shell.

The outlet side connection for the Staged Ignition Assembly is the same regardless which type
of SSOV (Siemens or Honeywell) is installed on the KC1000. Proceed as follows:

(a) Loosen the 1/4“ NPT union on the Staged Ignition Assembly (Figure 19) provided in the kit

and separate the 9” nipple and 1/4” to 1/8” reducing coupling from the assembly.

(b) Connect the reducing coupling to the 1/8” street elbow already attached to the Low NOx

Burner (Figure 20).
