Concentric V ent Adapter Kit Installation 1) The Concentric V ent Adapter Kits include: Where the use of “silicone” is called for in the following instructions, use GE R TV106 for the vent adapters and any general-purpose silicone sealant such as GE R TV102 for the air inlet pip[...]

10 e) On the male end of the stainless vent adapter , apply a ¼” wide bead of silicone approximately 1/2” from the end of the pipe. f) Insert the male end of the stainless vent adapter into the boiler vent collar until it bottoms out. g) Apply an additional bead of silicone over the outside of the joint and smooth out. h) Replace and tighten t[...]

C. Assembly of Crown Concentric V enting W ARNING Failure to follow the instructions could r esult in fl ue gas leakage into the combustion air or indoor air , resulting in unsafe or unreliable operation. • Do not lubricate concentric gaskets with anything other than water . • Do not attempt to cut any piping except as permitted in this sectio[...]

a) Determine the required length of the outer pipe. When doing this allow an additional 1” of length for insertion into the female end of the adjoining pipe. Mark the cut line on the outer pipe. b) Remove the plastic inner pipe by pulling it out from the female end. c) Cut the OUTER PIPE ONL Y at the point marked in Step (a) using aviation shears[...]

a) Start assembly of the vent system at the boiler . Lubricate the brown gasket in the boiler vent collar with a few drops of water . b) Push the male end of the fi rst fi tting into the boiler collar until it bottoms out. The male end of cuttable sections should go 1” into the collar until the insertion mark (made in Step 2d above) is covered.[...]

a) Cut a 5-1/2” diameter hole through the exterior wall at the planned location of the horizontal terminal. b) Measure distance “L” from the outside surface of the exterior wall to the end of the last fi tting as shown in Figure 1.12a. c) Add 1-1/4” to distance “L”. Carefully mark this length on the pipe as shown in Figure 1.12b. d) Re[...]

6) V ertical T erminal Installation - In addition to the vertical terminal, either a Flat Roof Flashing (80/125 PN 230533, 100/150 PN 230571) or Sloped Roof Flashing (80/125 PN 230535, 100/150 PN 230572) is required for this installation. a) Determine the center line of the terminal location on the roof. If the roof is fl at, cut a 5-1/2” diamet[...]

19 8) Condensate Drain Line - In systems where a concentric vent is used, all condensate which forms in the boiler or vent system collects in both the condensate vent adapter and the sump under the heat exchanger and leaves the boiler through the condensate trap. This trap allows condensate to drain from the boiler and vent while retaining fl ue g[...]
