conjunction with this procedure.
gas valve is Inlet Pressure and gas pressure
measured at the outlet of the gas valve is Burner
Manifold Pressure.
A. Preparation
1. Obtain two pressure gauges capable of reading
up to 35 in. W.C.
2. Disconnect the heater from the electrical supply
and close the fuel supply valve to the heater inlet.
3. Open the burner access panel.
4. Brush or blow off any dust and dirt on or in the
vicinity of the gas control valve.
B. Gauge Installation
1. Locate the inlet and outlet pressure taps, see
Fig. 27. Remove the pressure tap plug using a
allen key.

2. Securely connect a pressure gauge to each pressure
tap.
3. Open the fuel supply valves to the heater and reconnect
the heater electrical supply.
4. Start the heater

sure to the heater requires adjustment.
4. If the inlet pressures is correct and the burner manifold
pressure does not agree with that specifed on the
dataplate, then the gas control valve's internal pressure
regulator requires adjustment. See Fig. 27 for regulator
location.
5. Remove the regulator pressure tap cap screw and
adjust the internal screw to increase (clockwise) or de-
crease (counter clockwise) the pressure to the desired
pressure.
6. Install the regulator cap back onto the gas valve when
completed. Tighten securely.
