Crown Boiler BWC225, BWC150 manual

5.Installation of Optional Crown # 230873 concentric vent terminal - This terminal may be used for either horizontal or vertical venting. Do not attempt to use this terminal on a BWC150 or BWC225. All CPVC supplied with the vent kit must be used prior to connection of the vent system to this terminal. If the vent system is too short to permit this, do not use this terminal:

Horizontal Installations-

a.Cement the 4” diameter section of PVC pipe supplied with this kit to the Wye fitting using a primer and cement listed for use with PVC.

b.Cut a 4-5/8” dia round hole in the exterior wall at the location of the terminal (see Section A of this manual for permitted terminal locations).

c.If desired, the terminal can be shortened. If this is done, cut the 4” (outer) pipe so that it protrudes between 1-1/4 and 2-1/4” from the exterior surface of the wall. Cut the pipe squarely and de-burr both the OD and ID of the cut edge.

d.If the terminal is shortened, “dry-fit” the inner pipe in the Wye fitting. Cut the inner pipe so that it protrudes between 5-1/8 and 5-1/4” from the outside edge of the outer pipe.

e.Cement the inner pipe to the Wye, being careful, to keep the opposite end centered inside the outer pipe.

f.Slip the partially assembled terminal through the wall from the inside and orient so that the side outlet on the Wye is on or above the horizontal plane.

g.Seal the gap between the OD of the “outer pipe” and the exterior side of the wall with RTV sealant.

h.Cement the rain cap onto the inner pipe. If desired, the rain cap can be attached to the inner pipe with a field supplied stainless steel screw so that it can be later removed for cleaning and inspection. If this is done, drill a clearance hole in the rain cap and a tap hole in the inner pipe to accept this screw. A 1/2” mesh field supplied rodent screen may also installed between the rain cap and the inner pipe (Figure 1.21)

Vertical Installations -

a.Cement the 4” diameter section of PVC pipe supplied with this kit to the Wye fitting using a primer and cement listed for use with PVC.

b.Cut a hole in the roof large enough to clear the concentric terminal at the location of the terminal (see Section A of this manual for permitted terminal locations).

c.Use a roof flashing and storm collar to prevent moisture from entering the building. Seal the roof flashing to the roof using generally accepted practice for the type of roof on the installation.

d.Slip the partially assembled terminal through the roof from the inside.

e.Install the storm collar after verifying that the bottom of the rain cap will be at least 12” above the normal snow line. Apply RTV to seal the storm collars to the terminal.

f.Cement the inner pipe to the Wye, being careful, to keep the opposite end centered inside the outer pipe.

Cement the rain cap onto the inner pipe. If desired, the rain cap can be attached to the inner pipe with a field supplied stainless steel screw so that it can be later removed for cleaning and inspection. If this is done, drill a clearance hole in the rain cap and a tap hole in the inner pipe to accept this screw. A 1/2” mesh field supplied rodent screen may also installed between the rain cap and the inner pipe (Figure 1.22)

WARNING

•Do not attempt to use this terminal on a BWC150 or BWC225

•All CPVC supplied with the vent kit must be used prior to connection of the vent system to this terminal. If the vent system is too short to permit this, do not use this terminal

•Do not operate boiler without the rain cap in place.

•Method of securing and sealing terminals to the outside wall must not restrain the expansion of vent pipe.
