Question about Dyna-Glo Double Tag-a-long Heater

1 Answer

Could not get more then 72hours using 20lb tank on low

I bought two thinking I would get the advertised 110 hour running time on each thinking maybe it would make a difference if the tanks were filled at a different place but it still ran out around 70 to 78 hours. The tanks are 20 lb. tanks. The low setting claims to be 7,000 BTUs on this size tank. How come after using four tanks I still only get 70 to 78 hours per tank? What's wrong with these heaters? Is this a case of false advertising to sell a product? I also own a Big Buddy portable propane heater. It advertises its low setting at 4,000 BTUs and will run 120 hours on low using a 20 lb. tank and I am always in the ball park when I use that one. The reason I bought the Dyna Glo was the advertised 7,000 BTU setting on a 20 lb. tank and an advertised running time of 110 hours. I didn't think I could go wrong with nearly twice the BTUs using the same 20 lb. tank.

We bought a Colomen Road trip BBQ and only used it twice. Now it will not stay lite. We bought a new regulator to no avail. It is clean so it's not plugged. Please advise

Are you connecting to a 20lb tank or a 1 lb throw away? If you are connecting to a 20 lb tank, it sounds like the tank "checked" meaning the OPD valve shut down. Do you get a low flame? Let me know so we can further assist you.

I have a 20lb propane tank fells half full or better grill lights but won't heat up why? Put new tank on works fine.

Gas may have settled. Turn it upside down several times. Usually happens when it gets cold outside.

I have a Vermont Casting VM450SSP Grill that needs a new Hose Regulator-S/B Valve Assembly. I have ordered two separate times what "Appliance Factory Parts" thinks is the part I need and both...

This ma=y be a case of changes in parts for your VC Grill. The ownership of Vermont Castings changed 6 years ago, when Majestic Fireplace, who was then the owner went bankrupt and Monesson Hearth products bought VC in the bankruptcy. Shortly there after, Monesson made some sweeping changes to the grill line (your model was discontinued) and really up graded what Majestic Fireplace had done with that line of grills. Overall, they started building a better quality grill.

Unless you have a piped in high pressure propane gas system, the one that Appliance Factory Parts furnished you should work fine (based on what I saw on their website). In addition, if you purchased your grill, prior to the change in 20lb LP Gas Grill Tanks Valves, 6 years ago. Some manufacturers changed their grill hoses to conform with the new OPD Valve grill tanks. It wasn't required, they just did it, to avoid regulators locking up, when the tank valve is opened to fast.

Hope this helped answer and solve the problem for you. Happy Grilling!!

My7 Baby q doesnt get hot enought to sear steaks

Their are several things that can cause this problem:

1. The burner(s) need to be removed and thoroughly cleaned.
2, Low amount of gas in the tank.
3. The grill's gas regulator is partially seized.

The first two are easy for you to solve, The third one is to if you do the following:

Turn the gas tank valve OFF. If you're using a 20lb LP Gas grill tank, disconnect the hose from the tank and wait 5 minutes, If you're using a small 1 lb cylinder, turn it OFF and remove it from the grill. after 5 minutes, reconnect the hose to the tank or reinsert the small cylinder and turn the tank valve ON VERY, VERY SLOWLY (Slow motion, slow). Once the valve is fully open light the burner(s) and turn it to the highest setting. Did the burner light and does the flame height look correct? If so, you solved the problem. Just remember to always turn the tank valve ON very, very slowly.

If the above didn't solve the problem, you will need to replace the grill's hose/regulator assembly (if you're using a 20Lb LP Grill Tank). Which you can find at any home center or hardware store that sells gas grills and accessories. If you're using the smaller insert-able tank, you will need to replace the tank's hookup and regulator mechanism.

Hope this helped you to troubleshoot and solve the problem. Happy Grilling!!

Does not start. manual start doesnt work either.

First, is your grill on a cart or built in to an island? Secondly, are you using a 20lb propane tank to fire the grill or is it hard piped to the grill from your house? And finally, has it been converted from Propane to Natural Gas?

If you're using a 20lb LP Grill Tank are you sure there's still gas in the tank? Did you just installed a new, full tank recently and the problem started after that?

If the latter is the case, turn off the grill tank valve and disconnect the hose from the tank. Wait 5 minutes and reconnect the hose to the tank. Turn the tank valve ON VERY, VERY SLOWLY, until it's fully open. Light each burner one at a time and turn then to high flame. Do the flames look normal? Are they the proper height? Is so, you just solved your problem. Remember to turn the tank valve on very, very slowly after turning it off each time.

If you grill is hard piped from your house, be sure that the gas line shutoff valve is turned ON.

Hope this helps solve your problem.

How do i set the low pressure on the flotec switch

your pump should have a 20lb seperation ie. pump turns on at 20lb and off at 40lb or on at 50lb off at 70lb. under the cover of the switch theres two screws with springs under them.dont mess with the small one.the large one if you screw it down (right) will increase the pressure while maintaining the 20lb separation. one thing to keep in mind its fine to adjust the pressure BUT at the same time the air pressure in the tank needs to be adjusted to two lbs below the cut in pressure of the pump.

I believe the directions are in the top of the cover of the switch

Regulator Repeatedly Reduces The Gas Flow

The new regulators will automatically shut down or reduce flow if the it senses that the flow is too high (as in a line leak or break). It can also be folled if you open the valve too quickly. There is a special plastic plug that can reset a tripped valve in the new tanks. (Mosquito Magnet supplies one with their product).

The other thing is that there is a recall going on at Char Broil of defective thermometers that are reading too low.

2000 grand am died

Have you tried a new fuel filter? Or try putting two bottles of heat or fuel line cleaner in your tank some times when the tank gets low theres moisture or debris in the tank when it gets that low some times its good to run it completely dry and start over on a full tank. Maybe check the oxygen sensor or the catilletic convertor.

20 lb tanks

Yes you can use a 20lb tank to run the heater. I purchased a adaptor hose it hand screws into heater & screws onto tank works fine. Bought the adaptor hose at HD.
