Dovre is actually an old gas stove manufactured by what is now Hearth and Home Technologies. This is a discontinued model. visit www.quadrafire.com for technical support. If they won't or can't help you let me know I think I have the older tech manuals somewhere.

Powers on, then immediately shuts off. More detailed in comments below This is too aggravating!!!!!!! Characters characters


Hello Kathy: All clothes dryers work on the same basic principle...
1.) Air Flow
2.) Heat
3.) Rotation

Your problem may lie in your duct work configuration and how the exhaust gases are vented; the mere fact that you had blockage could have overheated the dryer's high limit thermostat and/or the thermal fuse...BUT, before I go any further...I need to talk to you about safety!

Gas dryers give off combustion gases that are toxic and DEADLY; DO NOT VENT YOUR DRYER UNDER YOUR HOUSE SLAB to the outside! Especially that you report that it gets WET inside that underground slab- it's against NFPA fire codes (municipal and state building codes, as well) to do that. If that slab ever collapses partially or fully, you'll have no way of knowing it and the toxic gases will back-up into your house.

The safer venting method should be done with 4 inch solid wall vent pipe; and should be vented directly outside. Maximum duct work (straight run of ducting without the use of any elbows) for your model gas dryer, is 65 feet.

If you are using 1- 90 degree, the total length reduces to 55 feet, including the elbow in that measurement

The use of 2- 90 degree elbows, 47 feet; for 3- 90 degree elbows, 36 feet, and for 4- 90 degree elbows, 28 feet- maximum length.

These are per your manufacturer's installation specifications.

Although you should not use more than 4- 90 degree elbows in your configuration, in the event you do, you would deduct 6 feet for each additional elbow used. You want to make sure that you can visibly see the vent pipe (to visually inspect it for defects or for ease of access to clean and service)- and never keep flammables of sorts near the vent pipe due to the heat that they radiate.

I choose solid vent pipe over foil or plastic (in my home, rental properties, and when I do installs) because lint does have a tendency to burn inside the duct work...which could lead to perforation and/or fire. Plus many manufacturers recommend solid vent pipe over other types; and I do not recommend using screws to connect solid vent pipe together with, since lint can catch on the exposed screw that protrudes into the duct. Use a combination of, heat rated duct tape and dryer vent clamps.

Some installers or readers of this will think that this is excessive, costly, and not necessary; through my life's experiences, I have seen unfortunate yet avoidable tragedies. (Don't forget to check & clean your dryer ducts at least once-a-year!- I do mine at the start and end of DST- the same day we change the clocks and the batteries on our smoke and carbon monoxide detector alarms.)

Now, concerning the rest of the troubleshooting process, are you getting any trouble code errors on the electronic panel? If so, what are they?

You have several choices, you can disconnect and remove the high limit thermostat and thermal fuse and check them for continuity or call tech support using their smart diagnosis procedures as outlined on page 35 of you owner's manual. Or you can disconnect the dryer at it's power source (outlet or circuit breaker) and wait a half hour; see if the electronic computer panel resets. Then try running the dryer.

Please let me know how you made out or if you need more help.

Have 75 gallon gas water heater. Can I run 90 PVC off top power vent without vertical PVC first? Have Richmond unit.


1) I believe you can immediately elbow the PVC pipe.
There is a limit for how many elbows can be used between blower and termination, and limit is determined by diameter of PVC pipe.

2) Copy following link for venting resources and typical Rheem and Richmond power vent manuals, and diameter-elbow pdf from Bradford White.
http://waterheatertimer.org/How-to-troubleshoot-gas-water-heater.html#venting

3) Richmond is Rheem. Product manual will show specifications for venting.
Product warranty is voided if installation does not follow specifications shown in manual.

Woodstove smokes into the house


I've never used a ceramic chimney, or seen one for that matter. I know that the dual walled vent pipe works better when warn/hot. Can't explain it real well but the inner pipe gets hot while venting the heat and smoke. And between the inner and outer wall is cooler air, which is drawn down towards the wood burner. Creates a suction by the exhaust out of the center pipe. Mine smokes up the house when I leave the doors open and when it's a low flame inside. I'm sure you've checked on the manufacturers' specs for venting but, if you don't already know, look into the thermal dynamics of a dual walled vent pipe. And also a ceramic as you have. Has to be something with your stove install or vent pipe. Hope this couch advise helps!

I boughta vermont castings model # 2610 cast iron radiance franklin stove it came w/pipes .............is it a direct vent or a b vent..reason why i am asking is he gave me a "t" pipe w/ screen...


It the opening on the stove is on top of the stove, it's a 'B' vent. If the opening is in the back of the stove it's a "Direct Vent". However, some models have a connection on the back that's facing up,. A 90 degree elbow can be used to convert it to a horizontal run to enter an existing chimney, but then it must elbow up to connect to the pipe that is required to line the chimney. You should not just stop the pipe above the damper. It needs to run all the way to the top of the chimney, then have flashing seal the chimney's clay liner and a termination cap on the top.

here is a link to the Owners Manual/Installation Instructions for a Model 2600. It installs the same way as the 2610. http://homeappliance.manualsonline.com/mdownloads/62b85343-a800-4898-85a1-3d6d3c524259.pdf

Hope this helps you sort things out and do a proper installation.

Is the gas stove Dovre model DV450, by heatilator, serial # GA384694 a B -Vent or Direct Vent?


Janny, generally with Heatilator gas fireplaces, the letters in the Model Numbers indicate whether it's a Direct Vent or a B-Vent. In your case, it's a Direct Vent. Had it been a B-Vent the Model Number would be BV450.

Hope this answered your question. Please be knid enough to rate my reply to you. Thanks.

Vent free wall heater starves for gas


The 3/4 pipe will provide enough gas provided that it does not have a lot of elbows in the run. The more elbows you have, the less gas you have at the end of the run.

I recommend that you call the company which provides you with the gas and have them come out and look at your problem. They will be able to analyze your situatioin and make a recommendation to you. This is a free service. Good luck with it.

Need to move the unit by dismantling


Remove the two screws on the side trim. Remove the two top screws from the filter panel. Reach behind the heater and pull the sock down on the vent pipe. unclip the two clamps holding the vent pipe together. Remove the plastic elbow off of the vent termination. Slide the heater to the left to slide the vent pipe off of the vent termination. Remove the gas line after shutting the gas off.
