Installation Prestige Triangle Tube Solo 110

Hello Members,
I am having contractors give estimates for the intallation of a Prestige Triangle Tube Solo 110 and I want them to use the chimney as a chase for venting. My chimney height is approx. 35-37 feet. One installer told me anything higher than 20 feet, I need an assisted blower motor and the efficiency of the boiler will be reduced. Is this True?

Call Triangle Tube and ask. I thought they listed the total allowable equivalent venting length in the manual, but didn't find it in a quick glance.

You want to look in the VENT SUPPLEMENT MANUAL.

You can go up that chimney NO PROBLEM.
I suspect that the boiler will be close to the chimney ?

Also you can pull your combustion air from the outside wall, the vent and intake DO NOT need to be in the same pressure zone as some of the others do as there are NO air switches to get all messed up.

GREAT boiler, we install 30 or more a year...
Little to no call backs

Ah yes, that's where I've seen it. Thanks TO.

Couldn't find it at TT, but here it is:

http://www.houseneeds.com/shop/manua...vcventsupp.pdf

Table 1 on page 3 sets out the limits. With 3" pipe, you can have a total equivalent length of 60 feet. "Equivalent" length means that elbows count more than straight pipe. They say 90-degree elbows count as 5 feet of equivalent length, and 45-degree elbows count as 3 feet of equivalent length.

So for a 38 foot vertical chimney, you've got 22 feet of equivalent length left to play with. If you can do the whole run with two 90s (10 equivalent feet), you have 12 feet of additional straight pipe left to go from the boiler to the chimney.

Or any combination of straight and elbows that doesn't add up to more than 60 feet....

But they also say that if you use 4" pipe, the limit goes to 100 equivalent feet from the 60 equivalent feet with 3" pipe.

Make sense?

For example

1 ft straight up off boiler = 1 ft
90 elbow to go across basement to chimney = 5 ft
straight pipe across basement = 8 ft
90 elbow to go up chimney = 5 ft
straight pipe up chimney = 38 ft

Total = 1+5+8+5+38 = 57 ft

Chimney venting

Thanks for the help Xiphias and ToHeating!
The space for the boiler is right next to the chimney approx 2 feet. My first contractor wants to charge me an additional $1300 to vent up the chimney. (I have not seen any others yet because of the Labor Day weekend but I'm setting up appointments for next week). I think that is expensive.
I'll see what the other contractors quote me.

Also would you use concentric venting for my application?
Appreciate your help.
