Crown Boiler CWD083, CWD220, CWD060, CWD165 Vent / Intake System Assembly, USE of Condensate Traps

FIGURE 16: USE OF CONDENSATE TRAPS

C. Vent / Intake System Assembly

1)General Assembly Notes:

a)Where the use of “silicone” is called for in the following instructions, use GE RTV 106 for the vent collar and coaxial terminal. Air inlet piping sections are sealed with any general-purpose silicone sealant such as GE RTV102. PVC air inlet piping sections are connected with PVC cement.

b)Longitudinal welded seams should not be placed at the bottom of horizontal sections of exhaust pipe.

c)Do not drill holes in vent pipe.

d)Do not attempt to mix vent components of different vent system manufacturers.

e)In some cases, there are differences between the vent system installation instructions in this manual and those in the vent system manufacturer’s manual. Where such differences exist, this manual takes precedence over the vent system manufacturer’s manual.

CAUTION

Vent systems made by Heat Fab, Protech, and Z-Flex rely on gaskets for proper sealing. When these vent systems are used, take the following precautions:

•Make sure that gasket is in position and undamaged in the female end of the pipe.

•Make sure that both the male and female pipes are free of damage prior to assembly.

•Only cut vent pipe as permitted by the vent manufacturer in accordance with their instructions. When pipe is cut, cut end must be square and carefully deburred prior to assembly.

2)Vent Collar Installation – The vent collar is shipped loose in the accessory bag along with two collar gaskets, the outlet orifice, and four 10-32 mounting screws. Verify that the 6 digit part number model number marked on the outlet exhaust orifice matches that shown in Table 6. Mount the collar and orifice as shown in Figure 17. If desired, the first piece of exhaust pipe can be connected to the collar before mounting the collar on the boiler.
