19 - turn the power on to the heater;
20 - turn completely counter clockwise
the screw “E” of Figure 12-6;
21 - Checking gas supply pressure
following Section 13.7. The minimum
gas supply pressure must not be
less than 3”WC (7.6 mbar) and the
maximum gas supply pressure must
not be higher than 13”WC (33 mbar).
22 - Verifying the CO2 rate and its
eventual adjustment following Section
13.8: The heater during its normal
operation, within a maximum altitude
of 4500 ft, has a CO2 exhaust rate
as shown in Figure 12-7. If not within
range of value shown, malfunctions
will occur.
WARNING!!!
The CO
(carbon monoxide) level should
not exceed values given in
Figure 12-7, when combustion is
correct. Failure to comply with
this requirement could result in
severe personal injury, death or
substantial property damage.
WARNING!!!
All combustion
measurements must be
performed with calibrated
equipment to ensure proper
reading and accuracy. Failure
to comply with this requirement
could result in severe personal
injury, death or substantial
property damage.
WARNING!!!
If the
combustion levels are not within
the range given in Figure 12-7
for the fi ring rate, shut the heater
down and contact your distributor
or the heater manufacturer
(see reference in the last cover
page). Failure to comply with
this requirement could result in
severe personal injury, death or
substantial property damage.
23 - check the capacity of the heater
following Section 13.9
24 - Attach to the front of the heater the
appropriate conversion label, found in
the conversion kit (see Figure 12-8 or
Figure 12-9), stating the new type of
gas adjustment of the heater.
a - Apply the label in Figure 12-8 if the
heater has been converted to
LP
GAS
;
b - Apply the label in Figure 12-9 if
the heater has been converted to
NATURAL GAS
.
