Just got back from the hardware store with this: It's apparently similar to Teflon tape that you would use on a water fitting, but made specifically for gas. There is also a compound available, but I chose to use the tape because I was told that the compound can be a bit messy.

Corrugated pipe is generally intended only to be used as the last connection to an appliance, in a living space where it not vulnerable to banging or jostling (usually behind or in a space at the bottom of an appliance), but where it can be seen and accessed if work is being done. It is not intended to be buried in a wall, where it could be pierced by a ...

Use of thread seal tape does not work on the fittings that screw directly into an aluminum propane regulator. I don't know if the changes in seasonal temperature cause the aluminum to contract and expand (or something else) but six months later the fittings will be loose and leaking. I suggest using a hardening compound.

If the house is unoccupied it's likely "winterized", which may include disconnecting the fuel tank. You'll likely have to contact the home owner or fuel supply company, and make an appointment for them to meet you and reconnect the tank temporarily. DO NOT RECONNECT THE TANK YOURSELF. If you do not own the property, it is not yours to muck around with as ...

I cannot fully answer your question, but it seems that New Hampshire simply uses the ICC guidelines for building codes, including for "Plumbing, Mechanical and Fuel Gas" which seems to be the key area here. Not being an ICC member, I can't access the documents, and neither the New Hampshire Statutes website nor the State Building Codes website reprints ...

When I first read this, my first instinct was "don't", and I think that still holds. You are mixing water, electricity and possibly natural gas in a single untested design, and if anything goes wrong your pool could drain out, you could get electrocuted going in the water, or you could even end up with a bomb. It's not worth whatever costs you'd save ...

Where is the tankless water heater to be located? If it is in a space that is heated, then freezing will not likely be a concern as there will be plenty of heat gain through the equipment enclosure. If freezing is still a concern, look for a tankless unit that has a electric element for freeze protection. This will use a lot of energy if the unit is located ...

It's possible, but unless your furnace is way over sized, you can't just stick a heavier box in the same packaging and burn wood in it. You can reuse the duct work and blower, but everything else would need to be replaced. Depending on how much heat you need, it may not make sense to place the fire box where your furnace is. Further more, you may want to ...

You're question is vague and has a couple sub-questions, so let me offer a little Q&A: Q: Are there any central heating furnaces that use propane? A: Yes Q: Can I convert an existing natural gas furnace to use propane? A: Perhaps, but only with a manufactorer-approved adapter. Propane has more energy than natural gas does, so you must not just swap out ...

You are really asking a flow question. How many CFM (cubic feet per minute) does a given size pipe supply. The upper limit will be the meter capacity/ pipe size from the street. Each device has a max flow rating. Add them up and compare to the size piping you are planning to use. Increase the pipe diameter as necessary (up to the size coming in to the ...

If the thermocouple is new, and we assume that it's good, then I'd wonder if it's positioned correctly? I don't know how your boiler is, with some of them you can re-position the TC with respect to the pilot, and it might be too far away. On a similar vein, are you sure it's locked in place and can't move? For instance, if it could vibrate around a bit, it ...

Call suburban, tell them that you don't want the tanks any more. Make sure you are present when they unhook so there is no damage to your connection. I recommend that you use a pair of tanks, so that there is always a spare on hand. One is disconnected and capped. (Bugs love to nest in the opening...) Note that for emergency heating you can go through ...

Certainly you do that and it will work to some measure. However, if the heating equipment is designed for natural gas, it will require some adaptation to work successfully with propane. In many appliances a refit kit is available which alters the gas orifice. However, the practical reason this is not commonly done is that a 40 pound propane tank will ...

One major problem is that most propane regulators are intended for small appliances, mostly less than 75,000 BTUs/hr typical of an outdoor grill. The Rinnai V65EP can use up to 150,000, so a regulator designed for a little more than that would be the desired fit. Shopping around, I notice many don't say what their maximum flow rate is, and of those which ...

Simple answer - yes, it needs to be rated to supply gas. Two reasons: water molecules are bigger, so permeability is less of an issue for water, hence your hose pipe may actually allow gas to escape gas is explosive, so any mistake here may be considerably more serious than getting a water pipe wrong If you need guidance, call your local gas company for ...

The main difference between most torches is the maximum temperature it is capable of handling. So you can use propane as the fuel in MAPP torch (which burns hotter), for example. The second difference will be whether it uses compressed oxygen, or just the air around it. If it uses compressed oxygen it will burn hotter. Approximate burn temperatures ( as ...

The tape you purchased is the correct tape for gas fittings. However, the fitting in your picture is a flared fitting. PTFE (Teflon) tape/pipe dope is only necessary on pipe thread fittings. This is because pipe threads are tapered - as you tighten the fitting, the threads bind together and deform slightly to create a seal. The pipe tape/dope helps ...
