- If the pressure value is greater then 0.8''W.C.
(or nears this value) there is an obstruction in
the flue pipe
- If the vacuum value is greater then 0.8''W.C.
(or nears this value) there is an obstruction in
the air inlet pipe.
The total pressure must be more then 0.15 '' W.C. If it
is not the case, there is not enough restriction in the
system. Verify the conformity of flue pipe, air inlet
pipe installation and size of the diffuser of the side
wall venter (two sizes exist: 1.688'' and 2.000'' model).

at ¼ Hz (2 seconds on, 2 seconds off). The burner
will try to start again after 60 seconds. The number of
recycle trials (for each call for heat) is limited to three
trials. After that the R7184 enters Lockout state. Led
flash at 1 Hz (1/2 second on, 1/2 second off).
