Installation:
1.The Relief Valve (RV) should be located in the beginning of the system.
2. The orientation of the Relief Valve must be positioned upright, as shown on the Figure
75b with a 45°Tee (T45) or on Figure 75c with a 90° Tee (T90).
3. The Relief Valve must be connected to our ANSI Flange Adaptor (FA). Bolts, washers,
nuts, and gasket (supplied by others) will provide a complete gas tight connection to
the 125/150 lb. ANSI flanged Flange Adapter.
4. The Relief Valve and the ANSI Flange Adpator Mus tbe connected to one of our tees
(T90 or T45).
5. The Relief Valve (RV) must be supported independently of the rest of the exhaust
system. The best method to accomplish this is to locate an Anchor Plate (AP) support
at the joint between the ANSI Flange Adaptor (FA) and the adjacent Tee (T45 or T90).
It is crucial that the Anchor Plate (AP) is properly secured to building structure so that
it can withstand the forces generated in case of delayed fuel ignition.

APPLIANCE AND FLANGE CONNECTIONS
SINGLE WALL ADAPTOR (SWA)
The Single Wall Adaptor SWA is the most commonly used appliance connector.
It is designed to clamp with a Retaining Band and Locking Band (BS) over a shank
type flue gas outlet.
Installation:
1- Slide the Retaining Band over the appliance outlet and tighten it with supplied bold.
2- Add a bead of sealant about 1/8" on the flange of the Retaining Band and another
bead on the flange of the Flue of the Adaptor SWA and mate those two flanges together.
Be sure to fill all the gap with the right sealant, depending on what appliance it is used
(See SEALANT Section ).
3- Put the Inner wall on the Retaining band.
4- Tighten the Locking Band (BS) to hold and seal the adaptor in place. See Figure 76
SINGLE WALL ADAPTOR WITH NOZZLE (SWAN)
The Single Wall Adaptor with Nozzle SWAN is the same as the SWA, but it has a nozzle
for test port. See Figure 77
