can a do it your it selfer install this unit
Asked by: mike
I am sorry I don;t think I can answer that as I don;t know your mechanical abilities or the codes in your area. If I was thinking about doing this myself I would certainly check with the code enforcement authority in my area first to make sure this is allowed and make sure my work was inspected by them before operating it.,

Can a home owner legally hook up a natural gas boiler, in Dauphin County Harrisburg, Pa 17112?
Asked by: Green
I can not speak with certainty on code issues in specific geographies. I would put that question to the building inspector, code enforcement officer or in some cases the fire department; in your area. In my experience many states do not have requirements for heating installation but do require permits, inspections and licenses to do gas piping as well as the connection of the water supply to the boiler. These should always be inspected and tested.

Is there a power vent available for a Sentry Stantfin gas boiler

Asked by: charger67
Yes you could put an after market power vent on this product. Or you could use the VSPH-150 which is another Slant Fin boiler but with a factory installed power vent. It is SKU number 202783247. If you go on the Home Depot web site and put that number int he search block it will come up. If you have further questions please feel free to give me a call Chris 978 651 3301

Can Gas & Zone Hookup be Moved to Left Side of Unit?

My gas line, water hook-up and zone feed lines are all to the left of my current boiler I'm looking to replace. Your picture shows what looks like all the hook-ups on the right side of the boiler. Are these switchable?
Asked by: Jim
The casting is fixed so you can not change the location of the gas connection or the tappings for the feed and return. So your options would be to 1.Utilize a different boiler that happens to match your installation better. 2. Turn the boiler around so the orientation would be better. 3. Plumb the gas line along with the feed and return over to the other side. Feel free to give me a call if you have more questions. Chris 978 651 3301

can this unit be converted to lp

Asked by: joey2112
Hi Joey2112, I contacted the manufacture to get you an answer. The manufacture stated this model can converted to LP. You will need a conversion kit. Part number is 414546. I did not find the kit on our web site. You would have to have your local Home Depot call the manufacture and order it for you. You would have to order M-F, Closed (Sat. & Sun.)

Can unit run on gravity

Can unit run on gravity
Asked by: Gerry
You are asking a very esoteric question that is much to complicated to fully address here and would require a knowledge of your specific system which I obviously do not have. However I find it intriguing and will try to give you some direction towards finding a solution. First, gravity systems were based on large thermal mass. This meant a large amount of water in the system as well as big pipe diameters and very specific piping configurations. In many ways this is a forgotten art. All of this was done so that the process of heat chasing cold would create flow. Today you will not find a residential boiler with water content and tapping sizes to accomidate this. I suspect that the current Dept of Energy rules would not even allow such a product due to modern efficiency mandates. Using any current residential boiler will not work in this way. They are intentionally built with less water and utilize pumps to create flow. So in a way the challenge you face is How do you put a modern engine in your model T. The magic will be how a modern boiler will be coupled to the older distribution system. That piping configuration will be critical in preventing the new boiler from cracking due to thermal shock, and would utilize a pump. I can;t tell you how to pipe it because I can;t see it. Now, I am speculating here, but I suspect there is a possibility you don;t want a pump because you don;t want or have electricity. That is going to be difficult. I do know that Amish communities have exemptions to the DOE laws and special boilers are made for them that do not use electricity and still utilize gravity. I am not in such a community and do not provide product to them but am aware of. As we are communicating over the internet I assume you are not either. However this information may help with internet searches for answers. I don;t know how much more help I can be, but if you want to call me you can. Chris 978 651 3301

Although I can answer technical questions do not have direct info on the Home Depot install programs. I would suggest you call your local store. They can answer questions specific to install programs in your area.
