WARNING
The Model6020 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.
Things to tell the Gas Customer
1
.
2.
Point out the regulators vent to the customer, and stress that
this opening must remain unobstructed at alltimes. Tell the
customer to be sure to check the vent opening after a
freezing rain, sleet storm, or snow to make sure ice has not
formed in the vent.
Show the customer the shutoff valves on the cylinders. The
customer should close these valves immediately if gas can
be smelled, appliance pilot lights fail to stay on or appear
higher than usual, or any other abnormal situation occurs.
3. Tell the customer to call your company to service the
regulator. lf the regulator vents gas or a leak develops in the
system, only a qualified gas serviceman should install or
service the regulator.
Operation
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 ihe inlet fitiing will shuloff gas frcm 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 1 0 psig, the "reserve"
side of the regulator will open and continue to regulate at
1'1"WC. Atthe 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.
lf 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 a soapy
solution, bubbles will show up around the area of the leak.
Never try to repair the leak yourself, always call a registered
gas fitter.
4. lnform the user that the supply cylinder
is not completely
empty untilthe red warning flag is fully visible in the indicator
window.
Exchange of cylinders
r
o
lf the device is enclosed in unvented compartment the relief
valve must be vented outdoors or adequate ventilation of
the 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.
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.
Description
CAUTION
The model 6020 regulator is designed for low-pressure
'11"W.C. vapor service and is not to be used for liquid service.
There will still be pressure in the empty cylinder.
The unit withdraws gas from one cylinder until pressure drops
to 10psig and then automatically switches to the reserve
cylinder.
This unit is for propane use only and only for 2 cylinder systems
The new cylinder now becomes the reserve cylinder, and the
red warning flag will not be visible at the indicator window. lf

other cylinder must be capped to prevent leakage or
contamination.
lmportant
Only qualified persons should install, adjust or service LP
gas regulators, if service is needed, contact your original
dealer or a qualified LP dealer. Always make sure cylinders
are properly filled and never accept cylinders that are over
filled. When replacing newly filled cylinders to the regulator,
check all connections for leaks with an approved leak
detector solution or a mixture of non-ammonia soap and
water. Never use matches or an ope flame. Note: Low
pressure regulators are designed to regulator LP vapor only.
Maintenance
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.
