Gas Connector Installation Instructions for Moveable Equipment
TM
Featuring the Blue Hose with StressGuard
WARNING Please read the following instruction booklet carefully. Failure to fully read instructions and follow
the cautions and warnings could result in severe injury or death.
CAUTIONS AND WARNINGS
1. The installation MUST BE in compliance with the National Fuel Gas Code (ANSI Z223.1) and all local gas
installation codes.
2. Installation and testing MUST BE performed by qualified personnel. Ensure that the gas supply and all the appliance control
knobs are turned off before connecting to the gas supply.
3. Gas outlet shall be in same room as appliance and the connector must not be concealed within or run through any wall, floor,
or partition. Flexible gas connections shall not come into contact with surfaces at temperatures in excess of 110°C (230°F),
sharp edges or wiring.
4. The final assembly shall be tested for leaks. CAUTION: Open flame or other sources of ignition shall not be used for this
purpose. Leak test solutions may cause corrosion. WATER RINSE AFTER TEST. To check gas supply piping system for
leakage, see National Fuel Gas Code Z223.1, NFPA 54 or CSA B149.1, Natural Gas and Propane Gas Installation Code.
If odor of gas is detected, turn off the gas to the appliance and have a qualified professional correct the
source of the leak.
5. WARNING: STRONG CLEANING SOLUTIONS OR CHEMICAL SUBSTANCES MUST NOT COME IN
CONTACT WITH THE CONNECTOR. These may include acids, solvents, fluxes with zinc chloride, or other
chlorinated chemicals. In case of contact, rinse down the connector with water and dry thoroughly.
6. An accessible manual shut-off valve must be installed at the outlet of the gas supply piping system upstream of the connector.
7. Contact with foreign objects, wiring or substances shall be avoided.
8. Avoid movement after installation on fixed appliances.
9. Bending and flexing of connectors on moveable appliances (e.g. those factory equipped with casters) should be limited to
pulling and pushing the appliance in or out for cleaning or maintenance.
10. Connectors are for use only on piping systems having fuel gas pressure not in excess of 1/2 psi (3.5 kPa) for the US and 1 psi
(7kPa) for Australia. Flexible connections are suitable for use with 1st, 2nd and 3rd family gases only on piping systems
operating at a pressure not exceeding 50 mbar.
11. DO NOT REUSE FOR ANOTHER APPLIANCE OR AT ANOTHER LOCATION.
12. In addition to the main gas supply shut-off valve, an approved accessible manual gas shut-off valve MUST BE installed
upstream of the gas connector (within 6 feet of the equipment it serves). Each piece of equipment must have its own
shut-off valve. DO NOT USE the quick-disconnect coupling is as the primary gas shut off.
13. WARNING: The quick disconnect MUST BE INSTALLED so that the gas enters the coupling half and exits the
nipple half. You must follow the flow direction arrows that are permanently marked on the coupling.
14. NEVER INSERT screwdrivers, probes, etc. into the quick disconnect coupling. The valve seat can be damaged or forced
off center.
15. The connector shall not be kinked, twisted, or torqued when installed.
16. Make sure that all fittings are tightened properly. When installing Safety System
wrenches (minimum size) are recommended as installation tools.
17. Adequate means must be provided to limit the movement of castered appliances. A restraining device is REQUIRED for all
types of moveable gas appliances. (ANSI Z223.1 & ANSI Z21.69).
18. The recommended restraining device for castered appliances is Dormont’s Restraining Device. Installation instructions for this
Dormont product are part of this booklet. This “restrainer” should be inspected as part of the regular maintenance and safety
procedures. Restraining cable MUST BE connected at all times when appliance is in use. Follow the instructions
on page 4.
19. When installing an equipment line-up with dual fed front manifold gas inlets, DO NOT use a quick-disconnect coupling.
20. For installations that require greater mobility, Dormont Swivel MAX gas connector assemblies are recommended.
21. Appliance MUST BE disconnected prior to maximum movement. Warning: DO NOT OVEREXTEND the gas connector
assembly. When moving equipment (for cleaning, maintenance, etc.), follow the instructions on page 8.
22. This connector complies with the standard for connectors for moveable gas appliances ANSI Z21.69/CSA 6.16.

INSTALLATION INSTRUCTIONS (FIGURE 1)
1. Before proceeding, CAREFULLY read this full set of instructions,
including the CAUTION AND WARNINGS section also the
INSTALLATION RIGHTS AND WRONGS section of this
instruction booklet.
2. The manual gas shut off ball valve (B), located in the gas manifold
line (A), must be in the fully closed (off) position. If there is no gas
shut-off valve in the manifold line, the main gas supply line valve
(not shown) must be turned off. DO NOT CONTINUE
UNLESS THE GAS IS TURNED OFF.
3. Remove the gas connector and contents from the bag or box.
4. The location of the two connection end points for the gas appliance connector, the gas supply line and the
equipment stub-out – can vary greatly. It is not practical to show every possible installation combination. These
instructions include several examples of common installations. The installer must always take great care to
ensure that the connector is not kinked, twisted or torqued when installed - and that the end fittings of the
connector are not subjected to sharp bends. (Please refer to Installation Rights and Wrongs). For installations
that may result in a sharp bend, Dormont Swivel MAX
®
gas connectors are recommended.
5. It is recommended that the main gas supply manifold be located 30''- 42'' off the ground. There should be pipe
tees pointed in the downward direction.
6. To facilitate moving equipment as close to the wall as possible, the two ends of the Dormont gas connector
should be offset to the side from each other. (+/–3'' offset recommended, see drawing 1).
7. Each piece of equipment MUST have its own approved manual shut-off valve. If there is not an accessible
manual gas shut-off valve for each piece of equipment, make sure that the gas has been shut off at the main gas
shut-off valve for each piece of equipment before continuing.
8. MANUAL SHUT-OFF VALVE INSTALLATION:
Female x Female valve ends
a. If the pipe tee is a male thread: Apply thread sealant (pipe dope) or thread tape to accessible pipe threads
located at the gas supply line. Thread the gas shut-off ball valve onto the male iron pipe and tighten wrench
tight. Locate ball valve as close as you can to the manifold leaving enough clearance to turn on and off.
Preferred valve position is vertical. (see Figure 1).
b. If the pipe tee is a female thread: Apply thread sealant (pipe dope) or thread tape to the threads of a pipe
nipple (not supplied/preferred length is three inches). Thread pipe nipple into female pipe tee off main gas
line. Then thread the shut-off valve onto the pipe nipple and tighten wrench tight.
9. WARNING: The SnapFast
®
Quick-Disconnect coupling (D) MUST BE oriented so that the gas enters
the female (valved) coupling half and exit the male nipple half. FOLLOW the flow direction arrows
permanently marked on the coupling.
FIGURE 1
OPTION 1
QD Device Installed at the Appliance:
This installation method, commonly used in North America, shows the
quick-disconnect coupling attached at the appliance side. The nipple
MUST
always be on the appliance side, attached to the appliance stubout or external regulator. This enables the operator to move the equipment away from the wall in an equipment line-up and safely disconnect
the gas connector from the back side of the appliance.

How to Use the Safety Quik®Quick-Disconnect Protection Valve
TO DISCONNECT:
1. Turn the easy turn valve handle to the off position (Diagram 1). Handle should be
perpendicular to the gas appliance connector.
2. Push the Safety Sleeve toward the handle. This will cause the unit to disconnect.
NOTE: The gas appliance connector cannot be disconnected until the valve is in the
off position.
TO RECONNECT:
1. Firmly push the quick-disconnect nipple, attached to the gas appliance connector, into the
coupling body (Diagram 2). This will allow the safety sleeve to return to its original position.
2. Turn the valve handle to the on position to allow gas flow to the appliance (parallel with the
gas appliance connector).
