Hazard
■
Do not disassemble the gas control valve.
■
Do not attempt to replace any components on the gas
control valve.
■
The gas control valve must be replaced if any physical
damage occurs to the control valve assembly.
■
Failure to follow this warning will result in fire or
explosions, leading to injury or death to humans and
livestock, and building damage.
ATTENTION
■
The following explains a typical procedure to be followed
in checking gas pressures.
■
Consult the dataplate on the heater or page 4 in this
manual for specific pressure to be used in conjunction
with this procedure.
A. Preparation
1. Obtain an L.B. White pressure gauge test kit - Part No.
500-20736.
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.
B. Gauge IInstallation
1. Connect the pressure test kit hose to the fitting at the
inlet of the gas control valve. Tighten securely. See
Fig. 15.
2. Connect the gas supply hose to the hose fitting on the
test kit. Tighten securely. See Fig. 15.
3. Reconnect the heater to its electrical supply.
4. Open the main fuel supply valve to the heater.
5. Open only the gas shut-off on the test kit to which the
main gas supply is connected.
6. Start the heater.
C. Reading PPressures
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.
D. Completion
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 line.
2. Disconnect the heater from its electrical supply.
3. Remove the gauge kit.
4. Reconnect the heater’s gas hose to the heater.
Tighten securely.
5. Reconnect the heater to its electrical supply.
6. Open the main fuel supply valves to the heater and
check for gas leaks.
ATTENTION
■
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.
