3. If the inlet pressures do not agree with that speci-
fi ed on the dataplate, then the regulator controlling
gas pressure to the heater requires adjustment.
4. If the inlet pressure is correct but the burner mani-
fold pressure does not agree with that specifi ed on
the dataplate, then the pressure regulator internal
to the gas control requires adjustment. Refer to
the following instructions. The burner box will need
to be opened and closed/latched as needed to
accurately set the gas control pressures.
5. If manifold gas pressure is different than dataplate,
remove the internal pressure regulator cap and
adjust the internal pressure regulator clockwise or
counter clockwise. See Fig. 31
