Does any one know the minimum clearances under porch?
I have openings on three sides and 4' above grade, reason I'm asking is to keep hidden from view, as requested.
Also, I know there is a finished product out there, sits close to wall and has very clean look,nicer than the white pvc cap its is ok'd by Buderus for the G142, but not sold by them,I can't remember the manufactures name.

I would contact the manufacturer

of the venting device, but to be totally honest based on the insurance claims I've seen, a lot, I wouldn't do it, period, JMEO!

Termination

The vent termination needs to be above the deck, not underneath. If left underneath, there will be risk of rot from the condensation, and the UMC is very specific as to correct venting. There are no products that I'm aware of that can be directly terminated under a deck, with code or mfg's approvals. Buderus will also advise you of the particulars for warranty. Yes, they make a termination plate to make a more attractive exterior VT.

Regretfully, it is

allowed in MA for a heat only application.

12. The vent system shall not terminate under outside decks or porches. Exception: If the appliance served by the vent system does not provide domestic hot water and the vent termination is at least four feet below the deck or porch. The porch or deck where the vent terminates shall not be enclosed so as to inhibit the dilution of flue gases.

Sorry about that!

Although

Although it may be allowed in this case as Firedragon pointed out, I would suggest against it. I have seen far to many customer's who try and do this to hide it and then complain of odors and end up having it relocated anyway. The company I work for (propane supplier) will not accept this setup. I would suggest even if the code allow's you check with your supplier and local authority to make sure they will. They have the final say..:)

I have concerns also about going under deck,and rather exhaust out front, but home owners not liking termination,I suggest the finish exterior trim that is more attractive, but can't remember the manufacturer or product #, it is stainless about 12x8 and has two three inch screened openings, one for intake and exhaust.What is it?
I'll call Buderus this week, maybe they can give me model.
Thanks

As stated already

Two concerns are at stake here. First, the appliance manufacturers test and certify their equipment with various types and brands of venting options and products and would desire that the installers utilize these configurations and products only. Variance from these approvals can become a liability issue.

Second comes the problematic conditions that can occur when discharging byproducts of combustion under a deck or porch. Water vapor is the biggest concern and ice buildup on or around the porch is most certainly a big concern....once again for liability reasons. You have seen the pictures posted here in the past of venting appliances, in particular condensing appliances, in close proximity of a porch. These pictures had the vent discharging beside the porch and not under it and had massive amounts of ice buildup happening on the porch. Go ahead and check with the manufacturer but I would reckon that they will probably say the same. Hope this helps.

Termination under deck

Buderus does not recommend and urge strongly not to install the termination under a deck. As stated by Glenn, code may state it can be done, but it can be (and has been) considered a nuisance and liability would be on the installer. Please work with the home owner to re-locate the termination.
The wall thimble supplied with the GA124 boiler is the only approved thimble. Please contact us if there are any questions. 1-800-283-3787.
Glenn and George - Thanks for the input.

You're welcome Joe

I really didn't think that your company's stance on this would be any different than any others. Liability is liability and certification is certification.

Aha!

I was waiting for someone to pick up on that one George and as usual you noticed the fine print. Just a word to let you know that nothing has changed. Better than a year or so ago Burnham Corp. took on a couple of more acquisitions. At that point in time, the Corporate name became Burnham Holdings and the residential products name became Burnham Hydronics, U.S. Boiler Co., Inc.. We did this because every company within the Burnham Holdings family of heating companies is individually operated and managed independantly from the others. We now stand at 11 plus companies dedicated entirely to the heating industry. I must say that I am flabberghasted that you picked up on that so quick! I only added that this afternoon!

Wow,

I knew of three, but eleven? You guys are on the way to being another Mestek?

I know what you mean about noticing, but it's part of what I do, LOL!
