High Pressure Gas Gauge capable of

reading up to 35 PSIG

1/4 in. Tee

1/4 in. Nipple

A. PREPARATION

1. Close fuel supply valve at LP gas supply container.
2. Allow heater to burn off gas remaining in it’s gas

supply line..

3. Close manual main burner valve on heater.
4. Remove gas hose from heater.
5. Remove hose adapter from inlet of pilot safety control

valve.

B. GAUGE INSTALLATION

1. Connect the following materials together in the order

as given. See Fig. 10.

-- Tee to inlet of pilot safety control.
-- Nipple to tee.
-- Hose adapter (as removed earlier) to nipple.
-- Gas hose to hose adapter.

2. Tighten all connections securely.
3. Connect gauge to tee.

C. READING PRESSURES

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 further 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.
-- Blockage in gas hose.
-- Insufficient size or quantity of LP gas supply

containers.

D. COMPLETION

1. Once the proper inlet pressure has been confirmed,

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.

5. Tighten all connection securely and check for gas

leaks.
