No draft?

If there's something wrong with the chimney like blockage, a power venter wont fix it. Fix the problem. A chimney in poor condition might put smoke and CO into the house. Have it checked and lined would be the best solution.

This is just the lastest chapter....

in an install not well thought out. The gas steam gas boiler he has was installed into a chimney that was not large enough for the new unit w/ the gas water heater.Power venting the boiler w/ forced draft drops the flue size down...although he will more than likely have the line the chimney w/ Z-flex the entire length...Field makes a unit to do this. kpc

It would depend on...

the chimney.I know burnham has an adapter for their 2PV to then vent into a chimney.I have seen a few JVi's vented into b-vent. And plenty of induced draft furnasties the same way. Now, that does not mean it was done proper....This job the whole thing(near boiler piping and venting) has had issues if I am not mistaken. The flue would have to be lined. kpc

As far as I know, the adapter may be obtained, but the chimney must be properly lined. Hope this helps.

Thanks Glenn...

I thought that you guys had one. You say properly lined...tile lined, Z-flex,b-vent ?I have been reading the Handy heating helper and it says no to the masonary as a cat3 appliance.I presume that is unlined masonary...kpc

My chimney has a new stainless steel liner. I will check with city inspector before allowing this install. I am not sold on the power vent being the correct way to solve my problems.

That is

no to a masonry chimney with a clay liner or unlined. It must be a properly sized, installed and approved metal liner and this only with the 2PV and no other boilers of ours that are draft induced. I personally would rather see it vented through the wall and would prefer to see a direct vented boiler to ensure proper combustion air.

Power venting will not meet code but the city inspector will pass it if it passes inspection of a qualified engineer.
