Replacing D80B, D892 or Competitive
Control with D896
WARNING
Bodily harm and/or death possible. Prevent
unsupervised gas flow.
Improper wiring (device malfunction) of the D80B,
D892, D896 or competitive devices can cause
unsupervised gas flow.
A wiring harness is included with most D896 models. Use the
harness to wire the D896 according to the furnace or boiler
manufacturer wiring instructions, if available; otherwise, follow
these instructions. If field wiring is required, see appliance
manufacturer instructions or see Fig. 8 for a typical wiring
example. See Table 1 for competitive wiring cross reference.
Always cycle system through at least two appliance
operations.
