Have a certified technician install all parts to prevent product damage and personal injury.
The model 6020 must be installed, operated and maintained in accordance with federal, state and local codes. The installation in most states must also comply with LPGA Codes of Practice.
Instructions Manual Information
1. Remove all parts carefully from the carton and attach the brackets to the underside of the regulator with two self tapping screws supplied.
2. Mount the regulator and brackets in suitable position firmly with screws supplied.
3. The outlet thread on the regulator is 3/8” FNTP and care should be taken to ensure clean and suitably sealed fittings are firmly attached.
4. The two pigtail hoses should be attached on either side of the auto changeover valve. Attach the TYPE I ends of the pigtail hoses one to each cylinder.
5. Ensure all appliances are turned off prior to the following tests being carried out.
The unit withdraws gas from on cylinder until pressure drops to 10 psig and then automatically switches to the reserve cylinder.
Regulator vent opening must remain unobstructed at all times. Check the vent opening after a freezing rain, sleet storm or snow and make sure no ice has formed in the vent.
Know where your shut-off valves are located on your cylinders. Close valves immediately if gas can be smelled, appliance pilot lights fail to stay on or appear higher than normal or any other abnormal situation.
Supply cylinder is not completely empty until the red warning flag is fully visible in the indicator window.
If the device is enclosed in non-vented compartments the relief valve must be vented outdoors or adequate ventilation of compartment must be supplied.
When the device is to be used outdoors, it shall be positioned or protected against direct penetration by any trickling water.
Place one of the two cylinders in “supply” by rotating the changeover lever (A) either way as far as it will go. The arrow will denote the “supply” service side. Open both cylinder valves slowly.
Gas will now flow from both cylinders through the pigtails into the model 6020 by way of the inlet fittings. When a pressure of 10 psig is reached beneath the 6020 diaphragm, the closing spring in the inlet fitting will shut-off gas from the “reserve” cylinder
The “supply” side of the regulator will continue to supply gas as long as sufficient gas remains in the “supply” cylinder. When pressure in the cylinder drops to about 10 psig, the “reserve” side of the regulator will open and continue to regulate at 11” W.C. At the time the “supply” cylinder becomes exhausted a red warning flag appears in the indicator window. This red flag indicates that a cylinder exchange can be made.
If a leak is smelt or detected the cylinders should be turned off at the handwheel valve and your gas supplier consulted. Never search for leaks with a naked flame. Always use soapy water solution, bubbles will appear around that area of a leak. Never try to repair the leak yourself, always call a registered gas fitter.
Exchange of cylinders
Before removing the empty cylinder, be sure to rotate the changeover lever (A) so that it points to the other cylinder Then close the valve of the empty cylinder to prevent air from entering the cylinder and disconnect the cylinder. Clean the cylinder valves outlet in the new cylinder. After the new cylinder is in place, slowly open the cylinder valve.
CAUTION there will still be pressure in the empty cylinder.
The new cylinder now becomes the reserve cylinder and the red warning flag will not be visible at the indicator window. If only one cylinder is left connected the pigtail or hose to the other cylinder must be capped to prevent leakage of contamination.
To avoid personal injury or equipment damage do not attempt any maintenance or disassembly without first isolating the regulator from system pressure and relieving all internal pressure.
