●Check and adjust pressure regulator
Supplied gas pressure regulator is factory set at 4”Natural Gas W.C,
and L.P. Gas pressure is factory set at 10”Natural Gas W.C;
Use a pressure gauge which is equipped with liquid (such as U-type
pressure gauge, the minimum value is 0.1mbar)
or a digital pressure gauge to test. Steps are
as following:
1、Open cabinet door, remove needle type
pressure joint screw arbor (Fig.8), then slip
rubber tube of pressure gauge over needle type
pressure joint;
2、Start the equipment in accordance with the
instructions, measuring gas supply pressure
(dynamic pressure) in the work state;
3、Access to the equipment if measured data
within the limits of Table 1, otherwise, you
will need to adjust gas pressure regulating
valve or contact gas supplier; Fig.8
4、Unplug pressure gauge after you accomplish pressure testing, then install
needle type pressure joint screw arbor.
Important: must screw joint arbor
in order to avoid gas escaping!
●Check and adjust thermostat calibration
All thermostats have been debugged before delivery, such as properly debugged
a variety of detailed parameters. Debugging by authorized off-sale service
technicians only.
1、Test equipment temperature with thermometer, put its thermocouple in middle
of boiler.
2、Adjust control details in place, read number when temperature stabilizes.
3、If the set temperature and measurement temperature difference at 10 degrees
Fahrenheit, please remeasure.
4、Delete number on the “B”, make sure reading drive is the initial state.
5、Keep B stable, adjust A by a bolt driver clockwise, dropping in temperature,
or increasing temperature anticlockwise.
6、Reset dial scale, remeasure temperature, confirm temperature whether adjusted
completely.
7、If modify successfully, please recover sealing screw.
