What do you suggest type of combustion intake air pipe for Burnham X-PV 85% efficiency cast iron gas boiler in Massachusetts? PVC vs steel pipe.
Can I reuse 9 year-old PVC pipe used in Buderus 95% efficiency gas boiler? Thanks.

    From page 8 of the install guide...

    Direct Venting – Combustion air is pulled directly from
    outside using the appropriate Direct Vent Conversion
    Kit shown in Table 2.2 with installer supplied PVC
    or galvanized air intake piping. See Appendix A
    for details on installing this boiler with a direct vent
    system.

    Mass. has restrictions on using PVC for the flue gas outlet.

    For the air intake it is fine as long as it is the right size and piped correctly
