Where can I find Temco fireplace replacement pipe? Had a chimney fire. Need 22 feet. Model #TCH4125 serial #AF291082
Unfortunately, we do not have any Temco chimney available as this company has been out of business for quite some time and all stock of their manufacturer-specific chimney lengths have been depleted.

I bought a used gas fireplace/stove that came with more chimney vent pipe than I will need to install in my manufactured home. The double wall vent pipe chimney is 7" diameter with a 4" pipe inside. The chimney will go through the ceiling and then through the roof. I believe it will be exactly vertical from the stove through the roof with no bends. Can you tell me what to look for in your store for a piece to keep the vent pipe away from the ceiling and going through the 4" of insulation above?

what venting parts are needed for the mirage outdoor with BBQ
If you are referring the the Mirage Stone line of outdoor fireplaces we offer, these should not be connected to any chimney system and should simply be placed at least 10' away from a home or structure and not underneath any sort of covering.

I am constructing a class B-type flue system for a Williams furnace 6551921. I plan to place it on top of a wooden room in my all metal RV barn. It is 60" to the metal roof and I have obtained 7' of B-type exhaust piping. Is there any recommendation on how to deal with the area where the flue pipe goes through the metal roof?
If you are going through a metal roof without contact to combustibles along the way, then you only need to cut out a hole with the proper clearance required for your pipe as listed by manufacturer. Above the roof, you will need a flashing, storm collar, and cap.

I have a direct-vent gas fireplace and live in a very snowy area. Is there a vertical chimney cap designed for heavy snow, or do I need to use a horizontal vent cap? Thank you.
On Direct Vent unit you have the choice to either vent the unit vertically or horizontally. In a heavy snow area you will have to watch for high build up of snow on the roof which can also block the cap. Some units have a horizontal "snorkel termination" that also may help your situation.

I need to replace the plastic screen and cover on the outside brick wall for a fresh air vent for a fireplace. The existing broken cover fits inside a pipe that is 3.5 inches. The closest size I can find for a replacement is 4 inches. It would take masonry work to replace the 3.5 inch pipe with one that is 4 inches. Is there a solution or smaller size cover available?
Unfortunately, we do not offer replacement outside air kit covers that will work with 3.5" diameter flexible duct.

My fireplace flue is not of the conventional type (picture below). I've had birds and squirrels come in and even an owl. What type of screen can I put on it?
While we do not have anything that would fit your chimney, we would suggest having a screen fabricated from stainless steel.

With wood-burning stoves and fireplaces, creosote will build up in the chimney. Creosote is a sticky residue that adheres to the inside of the firebox and chimney and often associated with higher pollution rate. The buildup is usually caused by using firewood with a high concentration of resin or wet firewood. If you are dealing with first or second stage creosote, check out our chimney brushes and cleaners to find what you need to take care of the mess.
Although maintaining pellet and gas stoves is much simpler than the wood-burning variety, consistency is the key to keeping it straightforward. It is recommended that you perform an in-depth inspection annually. As a note, unless you are very familiar with the parts and operation, it is a good idea to hire a professional to do this job. In addition, you should regularly empty the fire box and clear out any dust or soot; also, make sure that the door is secure to avoid leaking carbon monoxide into your home!
