INSTALLATION

7)InstalltheBackingPlateintothewallpenetra- tion heat shield and attach using 4 screws. Dia. 4.

8)Connect all pipe sections to unit and install into wall:

a)Measure pipe length required and cut to length. Hint: use the cut end of the 6-5/8" dia. outer pipe at the vent terminal end.

b)Push the pipe sections completely together, the minimum pipe overlap is 1-1/4". Secure all outer pipe joints by using at least two screws. Locate the screws at the bottom of the pipe so that the screw heads are hidden on the fi nal installation. Apply sealant "Mill- Pac" to inner pipe and high temp silicone sealant or "Mill-Pac" to outer pipe on every joint.

Hint: Apply sealant to female end.

c)Before connecting the vent pipe to the vent termination, slide the black decorative wall thimble cover over the vent pipe, then slide the Wall Penetration Heat Shield (Part # 946-202) over the vent pipe. Dia. 3.

d)Slide the appliance and vent assembly towards the wall carefully inserting the vent pipe into the riser vent terminal assembly. It is important that the vent pipe extends into the Riser Vent Backing Plate a suffi cient distance so as to result in a minimum pipe overlap of 1-1/4 inches. Secure the con- nection between the vent pipe and the vent cap by attaching the two sheet metal strips extending from the Riser Vent Backing Plate into the outer wall of the vent pipe. Use two aluminum screws provided to connect the strips to the pipe section. Bend any remaining portion of the sheet metal strip back towards the vent cap and cut off any excess, it will be concealed by the decora- tive wall thimble cover. See diagram 5.

8)Slide the decorative wall thimble up to the wall surface being careful not to scratch the paint. See diagram 5.

9)Back outside: Apply sealant to the 4" inner fl ue and slide the Riser Vent Front into the Backing Plate and fasten with 8 screws.

IMPORTANT:

When connecting the pipe to the Riser Vent, apply Mill-Pac to the inner pipe on theRiserVentTerminal,aroundthebead. Ensure that the vent pipe is pushed past the bead for a secure fit.

10)Seal around the outer edge of the Riser Vent Backing Plate.

VERTICAL

TERMINATIONS

1)Maintain the 1-1/4" clearances (air spaces) to combustibles when passing through ceil- ings, walls, roofs, enclosures, attic rafter, or other nearby combustible surfaces. Do not pack air spaces with insulation. Check the "Venting Arrangement" section for the maximum vertical rise of the venting system and the maximum horizontal offset limita- tions.

2)Set the gas appliance in its desired loca- tion. Drop a plumb bob down from the ceiling to the position of the appliance fl ue exit, and mark the location where the vent will penetrate the ceiling. Drill a small hole at his point. Next, drop a plumb bob from the roof to the hole previously drilled in the ceiling, and mark the spot where the vent will penetrate the roof. Determine if ceiling joists, roof rafters or other framing will obstruct the venting system. You may wish to relocate the appliance or to offset, as shown in diagram 8 to avoid cutting load bearing members.
