1. Start 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 at the inlet of the safety
control agree with that given on the dataplate? If so,
no fur ther checking or adjustment is required.
Proceed to section D.
3. If the inlet pressures do 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 LP gas supply
containers.

close fuel supply valves.
2. Allow heater to burn off fuel remaining in gas supply
line.
3. Remove gauge, hose adapter, nipple and tee.
4. Reconnect hose adapter to inlet of safety control
valve and hose to hose adapter.
