GAS PRESSURE CHECKS
AA.. PPrreeppaarraattiioonn
1. Obtain an L.B. White pressure gauge test kit -
Part # 20736.
2. Disconnect the heater from the electrical supply and
close the fuel supply valve to the heater.
3. Brush or blow off any dust and dirt on or in the vicinity
of the gas control valve.
4. Disconnect the gas hose from the heater.

1. Connect the pressure test kit between the heater and
gas supply hose. See Fig. 17. Insure both gas shut-
off valves on the test kit are in the closed position
when connecting the kit to the heater and gas supply.
2. Reconnect the heater to its electrical supply and open
the main fuel supply valve to the heater.
3. Open only the gas shut-off on the test kit which is
connected to gas supply.
4. Light the heater.
CC.. RReeaaddiinngg PPrreessssuurreess
1. With the heater operating, the pressure gauge should
read the pressure specified on the dataplate.
2. Does the reading on the gauge of the test kit agree
with that specified on the dataplate? If so, then no
further checking or adjustment is required. Proceed
to Section D.
3. If the pressure does not agree with that specified on
the dataplate, then the regulator controlling gas
pressure to the heaters requires adjustment.
DD.. CCoom mpplleettiioonn
1. Once gas pressure has been confirmed and/or
properly set, close the fuel supply valve to the heater
and allow the heater to burn off any gas remaining in
the gas supply hose.
2. Disconnect the heater from its electrical supply.
3. Remove the gauge kit and reconnect the gas hose
and electrical supply to the heater. Tighten securely.
4. Open the fuel supply valves and set building
