Why the 3/4" LP inlet? I plan 40lb DOT tanks with a Rego switchover regulator, 400k BTU/hr max (plenty!) but the regulators only have 1/2" outlets :-(

As it was explained to me, the gas is working under a low pressure. If you run low pressure though a long 1/2" pipe run, you will starve the heater of enough gas to lower the amount of BTU's it can produce. Yes, the regulator is 1/2" but opens to 3/4" pipe to reduce the friction. I had a short run in my house and did use 1/2" pipe to the heater and used a 1/2" to 3/4" adapter at the heater. Has been working this way for 9 years now with out a hic-up. It is a very reliable heater and have installed several over the years. YMMV

All I can do is tell you for the price , its well worth it. I' ve purchased a different unit but this one blows it away. Hot water any time all the time with easy hook up . Thats what I like. Call the customer help hot line to get the correct dip switch code. Outdoor units have a different code than indoor units.

When the unit fires up it can use up to 144,000 btu/ hr to "instantly get the wAfter up to heat, it then throttles back the burn to maintain the btu needed to maintain heating with the gpm thru put being. Used. This is what I understand . You should call the customer service technical dept and discuss with them.

these were 3/8 inlet and outlet for the tube that goes to thecontrol unit and into the burner. i am using it for a suburban water heater. it did not match for me so i am going to need to modify it. trying to find out the size of the inlet/outlet online is nearly impossible....

Pretty sure the description says "Available with 5/32, 1/4 or 5/16 In. flanges" so it probably isn't 3/8" :) In particular, a quick Google shows this part number is 5/16" inlet and outlet. K&N's website indicates they do not make an inline filter with a 3/8" I/O.

Yep, just get a mid-level regulator and you will be good! I went with a 7psi regulator and can create a ridiculously large flame.

We have an adaptor for a big tank for ours...but never had any problems. All I could imagine is that the tank is not screwed in correctly....sorry prob not very helpful

Where the gas line connects on my pro com 30000 btu heater is for a 3/8 " pipe . I had to get a fitting to go from 3/8" to 1/2" black pipe . Then i could connect my shut off valve using 1 made for 1/2" black pipe. I bought everything i needed at a menards store. Hope this is helpful.

No / This for an (H) tank. I am well pleased with this regulator, but will not work on (M) tank.. Good Luck to you !!!!!!!!

I'm believe not. The manual says to use only standard 20 or 30 pound capacity LP tanks (we also used a 15 lb. tank, too) with type 1 right-hand Acme threads. The hose hook-up that comes with the unit is small and I don't know if it would be the right size to hook up to something that big? I suggest calling their customer care phone number 1-877-338-0999 if you'd like to talk to the company about it. It never hurts to ask, and maybe they customize. Have a nice day.

The actual inlet and outlet outside diameters are 4.5". It could be a typo (I think) by the seller as on the keyboard, the "." and "/" keys are right next to each other. I connect the inlet/outlet to existing PVC pipes using rubber connectors.

Carl G I would like to know why you needed an oil lubricated pump? Changing to wet rotor may be an issue because of the clearances...if it stops it might only a small particle...I once had some system "goo" hat stopped one...it took washing it out with diesel to get it back running. Both engineering submitals indicate the NRF22 is about 2GPM less than the LR20BF at 10ft head...so here's the thing...depending on what system youre installing it on...most systems were designed for 160f DHW or 180f HWH water so by putting this in (I dont know your system but I would do it) you'll have a slighting lower flow rate...in DHW who cares as its no big deal...BUT in a HWH system your control valves will open more and this is a seriously good thing in modulating valves. There will be a larger delta T so I'd also lower my boiler temperature by at least 20f assuming youve some form of condensing boiler...this will help ensure youre in condensing mode. Circulate fluid...not temperature and you'll save a lot of money. Make sure your side stream filter is clean and check it a few times in the first 1-2 months because the more flow means the more crud is likely to get back to your HEX...if there isnt one put a Y strainer in and add a "sock" on the screen for a month or 2). A possible problem is how many zones open/ resistance decreases across too many different circuits/ zones...too many and there wont be enough. The system I installed this on it is actually the primary circulator through a 2xwall HEX serving the HWH off the DHW system...it works so well Ive been promoting it/ its been installed on 3 systems in this last year (its not my J.O.B but I do design energy and conservation projects as is my profession). Last, make sure the expansion tank is on the pump inlet side/ the return (DHWR or HWHR)...these high speed pumps cannot handle even a minimal bit of cavitation. All the best

It looks like the center inlet ones are 3/4 in. and the side inlet ones are 1/2 in. If you're ordering from HomeBrewStuff, contact them and make sure they are sending what you want. I ordered center inlet but they sent side inlet. They did give me a price break when I complained, and side inlet has worked fine for me.

it is 3/4 inch - You do have to use a few extra wraps of sealer tape. Now it does not go by a pressure so much as it does in reference to water flow. The switch on is a higher flow than switch off. The unit is a plunger type and is directional (you have to install correctly). It will not sense a drip - drip -drip but triggers at a low flow. Hope this helps

Both inlet and outlet are 1". Use a reducing coupler for the in, thats what I did. No setting for the pressure, there is only a pressure switch for on and of 30/50 psi.

Hi Edward,Yes, you can still use the gauge. You will need a two stage regulator that has a POL inlet connection. Your gauge would hook inline between your tank and then the regulator.

That's a long haul... Hope the point is not too deep.... Anyway the pump inlet is 1 1/4 so you'll want to adapt down from 1.5 pipe to 1.25 right near the pump

I was using a 3" ABS pipe with a Fernco adapter. The adapter had a 1/4" wall thickness which fit snugly inside the 4" ducting on the ventilator. A Schedule 40 4" PVC pipe at 4 1/2" OD will be too large, but it might fit inside the PVC pipe.

Hmm. I had to have the supply line from the LP tank. Perhaps "installation materials" includes whatever tools you need to cut a hole through the wall to install the intake/exhaust tubes? From my end, everything was supplied that I anticipated. I poked my own copper supply tube through the wall, with appropriate fitting, and connected the sucker. Works just fine.
