Hi,
I have a 1998 Commodore 28x64 with the above referenced oil furnace. Over the years the cap and spark suppressor have rusted off. I also needed to have new shingles installed so I wanted to do it all in one shot.
Now, however, I am having trouble finding a replacement for the chimney/roof jack. I have about 12" of the inside pipe still sticking up out of the top of the furnace, and none of the outer wall.

Can I buy a replacement that will just slip over the existing piece? It seems like it goes down thru the top of the furnace and is attached to something else inside.

I can do most basic repairs on the furnace like replacing the nozzle and such, but I think if I cant find a replacement part I am going to have to have an HVAC guy come in and do it. I dont have any issue with that.

I have the opening for the chimney watertight for now, but I cant run the furnace until I get the chimney replaced and it is starting to get chilly in the evenings.

Thanks in advance......

Hi,

You can replace the crown with this assembly: http://www.aberdeenhomerepair.com/store ... n-assembly

Anything else you need to replace the entire roof jack, which you can see among those listed here (ignore anything shown for the CMF furnaces): http://www.aberdeenhomerepair.com/store ... 7/Chimneys

Thanks,
Mark

Thanks, Mark. I have 38" from top of furnace to opening of roof, so should I go with the 903664? Pitch is about 4/12
