Simple Fireplace Termination Chimney Cap Installation Options.

mounting the fireplace chimney termination cap from the top

Install on to the top of the chimney when the chimney tiles are extended from the mortar of the roof top. Start each mounting bolt before pressing in place and tightening.

Insert One screw into the lower hole located in each mitered corner of the chimney cover band.  Just start the screw in the hole a few turns until all four corners have screws started.  The termination chimney cap is designed to press the support screws into the corners of the chimney tiles because the flue tile is strongest at the corner which makes this the best place for the attachment.

With all four installation screws started press the termination chimney cover onto the flue.  Press to secure evenly onto the flue and only tighten all four screws evenly once the chimney cap is deeply set in place.

Adding the leg kit to the chimney cap termination.

Adding the leg kit to the chimney cap termination. Use pliers to bend the edge straight where the legs will install into the chimney cap.

If the flue tile is not sticking more than 3/4″ above the mortar and will not allow the cap to tighten securely from above then we will need to add the leg-kit.

Installing the chimney cap with the leg kit is also very simple.  Place the chimney cover upside down and remove the four screws in the corners of the base.  Using pliers (I usually use a vice-grip wrench) flatten the “V” shaped metal strip inside the base at each corner.  Only flatten the edge; do not flatten or bend the slot directly below the V-shaped strip of metal.

Once the legs are installed as shown, insert 2 legs and press to compress and insert other 2 installation legs.

Installation legs insert inside the opening so the bolts hold tightly within the diameter of the cap.

Installation legs insert inside the opening so the bolts hold tightly within the diameter of the cap. All four legs mount tightly and then insert 2 about an inch to press other side in place.

The installation legs insert into the corners of the chimney cap cover as shown here and the bolts return to the corners to tighten the legs into the termination cap.

Insert a leg into the slot and align the holes.  Make sure the leg is positioned towards the inside of the chimney cover.  Use the bolts to tighten the leg to the base of the cover.  Tighten each bolt completely so the bolt-head is flush against the leg and repeat for all 4 installation legs.

Install the cover by placing Two legs inside the flue liner approximately One Inch.  Carefully press to compress the remaining two legs to insert them into the flue liner an equal depth.   Firmly press the chimney cover straight down until the base of the termination cap base is pressed against the flue liner edge — or as close as possible.

 

Before the chimney cover is installed your chimney should be inspected to be sure your chimney has been constructed properly.  A chimney and inner flue piping has to be installed by determining the amount of draft and pull necessary for the type of fireplace to ensure a proper draft.  An inspection will determine that a venting flue is constructed properly and is not in need to cleaning or repair and is clear of any obstructions.   Hazardous conditions have been commonly caused by bird, squirrel and other animal nests in addition to tree limbs, leaves, fallen brick or tile lining.

The vent pipe leading from the furnace/fireplace to the chimney should be thoroughly checked for deterioration, blockage and/or soot accumulation which can cause dangerous chimney fires.    Even though installing this simple chimney termination cap is usually easy for a non-professional, it is always a good idea to have a licensed chimney company install the termination cap so the chimney and flue are checked for safety.

When wood burning units are being vented the chimney should be inspected as often as every few days.  If the cover or screening appears dirty or sooty it follows that the inside of the ventilation flue is also dirty and sooty which can cause a chimney fire.

The top of the chimney termination is angled in the center and again at the edges so no moisture collects.

The build up could be something as simple as the type of wood being burned as fuel on the fireplace but the cause could also be slow venting; a slow draft that needs to be addressed.  Once this is noticed, use a Certified Chimney Sweep to inspect and clean the flue and make any suggestions to minimize further future build up.

If this chimney is venting a Gas Furnace or Gas Fireplace Extreme caution should be taken when temperatures fall below freezing.  Visually check the chimney cover daily for possible frost, snow, freezing rain or ice build up.   If venting properly the hot draft of venting air and flue gases from burning fuel should prevent any frost build up on the chimney, piping, and termination chimney cap.  However, improper burner settings or conditions, obstructions or restrictions that could develop in the chimney could cool these escaping gases.   If the gases venting are cooled down in the drafting there could be a build up of frost and ice on the cap.  This kind of obstruction can become deadly dangerous immediately.  If there is ever any frost build up in a chimney termination cap in use often, call a licensed chimney sweep immediately.

Carbon monoxide build up in doors due to a blockage or poor drafting in the chimney flue may cause drowsiness, headaches, and/or nausea in its early stages which is a minor discomfort serving as a warning of carbon monoxide danger.   Carbon Monoxide Exposure Can Be Fatal if Chimney venting and termination is not properly established and maintained.

Please Be Safe.

Contact us with any questions — We would like to be able to help but since we’re in South Florida you are probably going to be better served by locating a local fireplace company that can inspect the flue and chimney and clean the lining as necessary while testing the ventilation drafting.
