GAS PRESSURE CHECKS

C. READING PRESSURES
1. Light the heater. With the heater operating, the
pressure gauge should read the pressure specified on
the dataplate or in the specification section of this
owner's manual.
2. Does the pressure reading agree with that given on the
dataplate? If so, no further checking or adjustment is
required. Proceed to section D.
3. If the pressures does not agree with that specified on
the dataplate, then check the following:
-- Improper regulator for heater.
-- Regulator out of adjustment.
(Replace if necessary).
-- Blockage in gas hose.
-- Insufficient size or quantity of propane gas supply
containers.
D. COMPLETION
1. Once the proper pressure has been confirmed, close
fuel supply valves.
2. Allow heater to burn off fuel remaining in gas supply
line, and allow the heater to cool.
3. Remove the gauge.
4. Install allen plug into manifold, tightening securely.
5. Check for gas leaks.
