APPLIANCE ADAPTER INSTALLATION:

1. Apply a bead of sealant to appliance collar approx. 1” from end of collar (Figure 5).

2.Remove all oil and grease from the inside of the appliance adapter, and apply a bead

	of sealant to inside of adapter ½” from end (Figure 5).
3.	With a twisting motion, assemble the appliance adapter onto the appliance collar.
4.	Using a mallet and block of wood, drive the adapter onto the appliance collar, using
	care to avoid damaging the appliance collar or the adapter (Figure 6).
5.	Assemble adapter clamp halves using the supplied 5/16” bolts and square nuts, and
	install the appliance clamp onto the adapter and tighten securely (Figure 5).
6.	Install the supplied self-drilling, self-tapping anchoring screws through the 4 holes in	Figure 5
	the appliance clamp into the appliance collar (Figure 6). No pilot hole is required.

7.Apply sealant to the end of the adapter and anchoring screws. (Figure 6).

8.After testing and burner adjustments have been made, apply sealant to the supplied 3/8” sampling port plug screw and install the screw in the sampling port (Figure 6).

9.Maintain the appliance manufacturer's clearances to combustibles. If the appliance collar is within 18" of combustible material, wrap minimum 1-1/5" ceramic insulation (installer-supplied) around the exposed portion of the termination inner pipe and appliance adapter (Figure 10).

JOINT ASSEMBLY: VENT PIPE TO TERMINATION AND APPLIANCE ADAPTER

If necessary, the vent pipe may be cut to length with a hacksaw or cut off saw. CAUTION: Use safety glasses and other appropriate safety gear.

1.Pull outer vent pipe back 1”-2” from inner vent pipe end and remove insulation (Figure 7).

Figure 6

2. Slide Cover Sleeve onto end of vent pipe a few inches back from end of outer vent pipe
	(Figure 7).
3.	Slide Cover Ring over stop bead on termination inner pipe or appliance adapter (Figure 7).
4.	Assemble inner pipe clamp halves using the supplied ¼” bolts and square nuts, and
	position inner pipe clamp ¼” from end of inner pipe (Figure 7).
5.	Remove all oil and grease from end of termination inner pipe or appliance adapter, and
	apply a bead of sealant to between the stop bead and retainer bead (Figure 8).
6.	Apply a thick bead of sealant to inside of inner vent pipe ½” from the end of pipe, working
	the sealant into the corrugations (Figure 8).	Figure 7

7.Push the inner vent pipe onto the termination inner pipe or appliance adapter all the way up to the stop bead.

8.	Tighten the inner pipe clamp bolts until both clamp halves are within 1/8”
	of each other at each end (Figure 9).
9.	Slide the cover sleeve and cover ring together to engage the ring in the
	groove of the sleeve, and tighten the cover sleeve clamp (Figure 10).
10.	To maintain 1" clearance to combustibles, wrap minimum 1-1/5" thick
	ceramic insulation (installer-supplied) around the exposed portion of the
	termination inner pipe
	(Figure 10), and
	secure with foil tape
	(installer supplied).	Figure 8
