This is my first post here. Sorry for this lengthy post, but I want to provide as much info/background as possible to get your advice. This is my NG conversion set up, I've attached two pics below to show the installation:
1. New factory sealed Weber NG manifold p/n 67610
2. New Maxitrol regulator p/n RV47L with ½” NPT connections (0.5 psig, Po 4.0”-8.0”)
3. New MB Sturgis NG/LP 10 ft. 3/8” ID gas hose p/n DG-3874
4. 3 new brass fittings/adapters to interconnect these parts
5. Megaloc blue thread sealant for regulator connections.
I’m the original owner of a Weber CEP-310 LP version bought brand new in Canada in 2008. This bbq has run well over the years, but I’ve moved into a house with an external valved NG quick disconnect. So I finally decided to make the switch from LP to NG. I bought the conversion kit from Majestic in the US (part 2 thru 4). This was my first mistake. I did not find this forum until after having purchased the conversion kit. That was my second mistake. After having found this forum, I purchased part 1.
The burners are still original and are discoloured and have a slightly rusted appearance. I gave them brushing when cleaning the bbq last week. After having installed these parts and passing leak checks, I lit the bbq. I could immediately hear the flow of NG, much more audible than LP. Lighting was easy. The flame burned aggressively and waved around a lot, with the control knob at high. I adjusted the air shutter to wide open, this reduced flame height and burned very blue. But the flame height still seemed too high and aggressive. Reducing the control knob to low did not result in any flameout/sputtering, the control seemed good.
I set the other two burners’ shutters wide open and set their control knobs to high. Easy lighting, with similar flame characteristics. I set all control knobs to high and videoed a heatup cycle. It took 38 sec to go from 200F to 400F. I have not converted a bbq, I have created a blast furnace ;-( This temperature rise seems far too quick for my liking, but flavourizer bars and SS grates are removed from the bbq. Running LP never achieved this type of heating “performance.” Also, I think the flame tip will touch the flavourizer bars at times, not what I want.
I’ve attached a third pic of the flame pattern on high. I’m asking your for your advice on next steps to take. My first instinct is to measure NG pressure, but I have no devices to do this. Note I do have a smooth acting isolation valve my house’s external quick disconnect. It appears to be a ball valve, it has a 90 deg stroke. Could I make use of this to throttle NG to the bbq ?
One final note for you. I want to run a NG extension line 33 ft to where my bbq’s permanent home on the patio will be. Currently, the bbq is moved next to the house’s NG quick disconnect, for testing purposes only. This will introduce some pressure drop and might help tone down my converted bbq’s performance, but I'm not expecting much.
