C. Reading Pressures
1. Open the fuel supply valve to the heater and position
the heater's power switch to ON. The heater should
light. With the heater operating, the pressure gauge
should read the pressure specified on the dataplate.
2. Does the reading on the gauge agree with that speci-
fied 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 the
gas supply pressure to the heater(s) needs to be
adjusted or the gas supply piping must be verified of
proper size
for the heaters installed.
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 hose.
2. Position the ON/OFF switch to OFF.
3. L-40: Remove the gauge kit and install the 3/16 in.
allen plug, tightening securely.
H-40: H-40 remove the gauge and reconnect the gas
hose to the solenoid valve.
4. Open the fuel supply valves and position the heater's
switch to ON. Check for proper operation after the
heater lights.
