fisher Posted February 13, 2013 Report Share Posted February 13, 2013 (edited) Just bought a natural gas BBQ with 74000 btus and am getting different opinions on size of hose to run from the gas line to the BBQ. One guy says with 74000 btus I should use 3/4 hose whereas another guy says 1/2 inch is fine . There is a significant difference in price ...anyone have any insight? I want maximum heat output but don't want to go bigger on hose size if not needed Also any idea of what should I expect to pay (the connection iwould be from my basement with a T on the man line already capped to be connected to thehose. He would need about 15 feet of hose from the cap to where the bbq would rest . he will need to drill to the outside (which is easily accessible). Thanks Edited February 13, 2013 by fisher Link to comment Share on other sites More sharing options...
John Posted February 13, 2013 Report Share Posted February 13, 2013 Can you provide a little more info? If it's a commercial unit with multi burners etc., chances are you will need 3/4" to provide enough LPG to the unit to fire all of the burners at max. What is the make? What hose is recommended by the manufacturer? BTW there shouldn't be a huge difference between 1/2" LP hose and 3/4" LP hose...PM me if you like..

fisher Posted February 13, 2013 Author Report Share Posted February 13, 2013 (edited) Hi John, thanks for the reply. it is a Napoleon with 4 burners (residential unit) that I bought at Canadian Tire. Your suggestion of contacting the manufacturer is a good one and I am a little embarrassed that I did not think of that myself. I guess I was just too excited that I'd be grilling again after my propane bbq bit the dust over 2 months ago and never thought of that! I just tried their number and they are closed. Will give them a shout in the morning. Edited February 13, 2013 by fisher Link to comment Share on other sites More sharing options...
livinisfishin Posted February 13, 2013 Report Share Posted February 13, 2013 I work for a napoleon dealer. 1/2 " hose will be fine. Is it a prestige 450? Also it sounds like you are running the hose through the wall. Thats a no no. Hard pipe from your basement to out side then you can attach the hose. Typically bbq lines run $150 for the first 10 ' and $10 a foot after. Thats what my company charges. Link to comment Share on other sites More sharing options...
livinisfishin Posted February 13, 2013 Report Share Posted February 13, 2013 Just read its from canadian tire..it wont be a prestige 450. Link to comment Share on other sites More sharing options...
fisher Posted February 13, 2013 Author Report Share Posted February 13, 2013 Thanks for your reply. This is the unit I got... http://www.canadiantire.ca/AST/browse/2/OutdoorLiving/BBQs/NaturalGasBBQs/PRD~0853073P/Napoleon+Legend+RSIB+Natural+Gas+BBQ.jsp?locale=en Could you confirm the above unit would only need a 1/2" pipe? As for the gas fitter (if that is their professional name), I am not sure what their plan is (ie. they may in fact be tying into the cap in my basement with a hard pipe to the outside and then the rubber hose..but I will make sure they actually do that..thanks for that info.) So in that case, I would say it is a 5 foot pipe to outside and then maybe another 10 foot hose from that point to the bbq (just in case I need to move it around for some reason).

pidge Posted February 13, 2013 Report Share Posted February 13, 2013 Yup you got it Fisher. The guy would likely come off the already capped "T" in the basement, run some pipe from "T" to outside wall. Secure pipe on outside wall with hangers/clips and install an outdoor shutoff valve. On the downstream side of that valve goes a quick disconnect and thats about it. Plug the rubber hose supplied with the BBQ into the quick connect and VOILA!!! your cooking with gas. For 5' of pipe and labour maybe $300 or so I'd say. Link to comment Share on other sites More sharing options...
livinisfishin Posted February 13, 2013 Report Share Posted February 13, 2013 Pidge is right the natural gas model should have the hose and quick disconnect included. It should be a 10' hose. Not sure of the diameter of it but i would guess that its half inch. If its the regular stlye hose you have to reduce the main line down to a 3/8" nipple in order to adapt your gas line to the hose fitting. Link to comment Share on other sites More sharing options...
fisher Posted February 13, 2013 Author Report Share Posted February 13, 2013 I was quoted $300 for 1/2 inch and then $400 for 3/4 inch..is there any benefit of going with the 3/4 inch? It seems that there will not be since I have to scale back down to less than 1/2 inch where it gets connected to the bbq line anyway. Link to comment Share on other sites More sharing options...
livinisfishin Posted February 13, 2013 Report Share Posted February 13, 2013 Ok i thought you were talking about the hose size..not your main line size. 3/4" pipes carrying capacity is higher then 1/2". How far away is the farthest Gas appliance located from the meter? I need to know a pretty accurate measurement of longest measured run in the house. For instance if its 50' a half inch line off of the main will supply 95000 btu/h Link to comment Share on other sites More sharing options...
fisher Posted February 13, 2013 Author Report Share Posted February 13, 2013 Thanks again...and sorry for the confusion. From what I gathered here and also speaking to Napoleon, and based on the short distance from the main line to the barbecue,it looks like I would only need 1/2 inch pipe to connect to the hose. I also found another guy that a friend of mine used that is TSSA ceritfied/insured.. that would do it for $225. Much better. Link to comment Share on other sites More sharing options...
pidge Posted February 13, 2013 Report Share Posted February 13, 2013 Yeah it's handy to know a gas fitter. Wouldn't hurt to ask for a 2nd shutoff installed inside as well. When you go out fishing no one creeps around your backyard and for dirt throws on the outside valve. Just sayin. Link to comment Share on other sites More sharing options...
torco Posted February 14, 2013 Report Share Posted February 14, 2013 learned alot here...planning to go natural gas this year as my propane bbq is almost done. Looks like a sweet grill Link to comment Share on other sites More sharing options...
danc Posted February 15, 2013 Report Share Posted February 15, 2013 I could do my own gas fitting but prefer to stick with propane for portability. I bar b que a lot, both summer and winter, so I move my machine around quite a bit. In summer it's out on the patio. Depending on the heat and time of day, I might roll it over to a shady spot. In winter it's right outside the back door. Not worth the savings in my opinion. Link to comment Share on other sites More sharing options...
