CAUTION
Intake PVC piping must be assembled using
cement. This ensures that the intake is air
tight and will not allow contaminants
to enter the boiler from the boiler room.
Cement must be free- owing and contain
no lumps, undissolved particles or any
foreign matter that adversely a ects the
joint strength or chemical resistance of the
cement. The cement must show no gelation,
strati cation, or separation that cannot be
removed by stirring.
Cements for plastic pipe are ammable
and should be kept away from all sources
of ignition. Proper ventilation must be
maintained to prevent cement vapor
hazards. Avoid contact with skin and eyes.

3. All alternative individual venting arrangements must result in an intake
pressure drop not to exceed 2.5" w.c. (Consult factory for assistance.)
4. All common venting arrangements must result in a pressure drop of less
than 0.1" w.c. in the common header. (Consult factory for assistance.)
NOTE: Intake PVC piping must be assembled using cement. This will ensure
that the intake is air tight and will not allow contaminates from the boiler
room into the boiler. The cement shall be free owing and contain no lumps,
undissolved particles or any foreign matter that adversely a ects the joint
strength or chemical resistance of the cement. The cement shall not show
gelation, strati cation, or separation that cannot be removed by stirring.
Cementing Joints
Adhere to the following procedure (per ASTM D2855) (see Figure 13):
FIGURE 13 AIR INTAKE BOILER CONNECTION
1. Measure and cut PVC pipe to desired length.
2. Chamfer end of pipe, removing any ridges or rough edges. If end is not
chamfered, the edge of the pipe may remove cement from the tting
socket and result in a leaking joint.
3. Clean and dry surfaces to be joined.
4. Test t joint and mark depth of tting on the pipe.
