Cleaning heat exchanger ﬂ ue side, 155

(continued)

Figure 106

Accessing the burner or heat exchanger (see Legend on page 124 )

NOT

attempt to remove the burner from

the heat exchanger cover plate without first
removing the heat exchanger cover plate from
heat exchanger. Damage to refractory will result.
This damage is difﬁ cult to detect without the
removal of the cover plate.
