e. If necessary, turn the screw on the ratio regulator, see Figure Midco 1
below, in order to adjust the manifold pressure. This is done by
removing the black plastic cap, and using a flat head screwdriver to
adjust the set point. Turn clockwise to increase the pressure.
13. Set High Fire adjustment:
a. With the burner off, install a barb fitting on the 1⁄8
′′
NPT pressure tap
for manifold pressure test point, See Figure GT1, Item 3
b. Set the burner power to 100%
c. Verify that the manifold pressure is the same as marked on the Burner
Rating Label(s) for the actual firing rate, for the IAQH-1000 unit, this
should be set at 2.2 inH20 or 5.5 mBar for Natural Gas or 1.2 inH20 or
2.98 mBar for Propane Gas
NOTE: At elevations above sea level increases in manifold pressure
settings may be required to achieve full rated input BTU - contact factory
for more information
d. If necessary, adjust the Fhi (fan high) setting on the SCEBM-2 module
(Figure RTC) until the desired manifold pressure is achieved. To adjust
Fhi:
i. Press and hold the enter key on the RTC controller to enter the
program menu, hold the enter key down for 3 seconds until
“APP” is displayed. Use the up and down arrow keys to navigate
to the desired parameter as shown in column 1, in this case fHi.
To edit a menu parameter, press the right arrow key once on the
desired parameter. The current value of the parameter will be
displayed. Use the up and down arrow keys again to edit the
parameter. Press the enter key to save changes made or press
the left arrow key to cancel without saving and return to column
1. If a key is not pressed for 20 seconds or the enter key is held
for 3 seconds while in program mode, the control will return to
normal mode.
NOTE: Only adjust Fhi settings from factory settings, this number
does change with elevation and should be set for each and
every installation.
e. (See figure RTC 2 for a full menu map and layout)
