Stainless Secondary Air Tubes Lopi Endeavor, 1750 wood stove, Revere, 98900233

Description

This listing is for a stainless steel secondary air tube replacement kit for Lopi Endeavor, Republic 1750, and 1750 wood burning stoves, and for the Lopi Revere fireplace insert.  Replaces Travis Industries / Lopi part number 98900233.  Although a bit lengthy, please read the entire listing...
This kit includes the following:  three stainless steel perforated tubes, three steel collars, and six stainless steel spring pins.
I have owned a Lopi Endeavor stove for 11 years.  It is a fantastic stove.  There are three secondary air tubes in the top of the firebox, just below the baffle.  These tubes introduce secondary combustion air through perforations in the tubes, which allows for more complete burning and increased heat output.  However, these tubes will eventually fail (crack and bend) and require replacement.
I am a retired pipefitter, and fabricate these replacement stainless steel tubes myself.  The tubes are type 304L, heavy-wall stainless steel pipe.  I include six stainless steel spring pins in the kit (each tube takes two pins) - my experience has been that the spring pins lose their "springiness" over the years.  I suppose this is due to the many cycles of high heat and cool-down in the firebox.  Also included in the kit are three steel sliding collars which, in conjunction with the spring pins, keep the tubes locked in proper alignment.
Here are some examples of feedback that my secondary air tube customers have left for me:

Installation is not difficult.  You will need a hammer, vice-grips, long-nose pliers, and possibly a punch.  Make note of the orientation of the perforations on each tube - the middle and rear tubes are the same, having 1/8" perforations that face straight forward, while the front tube has 3/16" perforations that face forward, but pointing down at a 45 degree angle.  Use the vice-grips to grasp, twist,  and pull out the old spring pins.  If there isn't enough pin sticking out to get the pliers on, you can use a punch and hammer to drive them up into the tubes.  Slide the collar to the left an inch or so, and lower the right side of the tube, and pull loose from the stationary collar on the left.  Slide the collar over the new tube, insert the left end of the tube into the stationary collar on the left, and slide the collar to the right, over the short pipe stub.  Use the closed long-nose pliers to line up the right-hand hole in the sliding collar with the hole in the short pipe stub on the right (a #2 phillips screwdriver or a punch also works well for this).  Use the long-nosed pliers to grasp the spring pin, and use the hammer to tap it into the hole that you just lined up.  Be sure to keep the spring pin straight.  The spring pin can be a bit difficult to start in the pipe stub, but it will go in, so stick with it.  After you get the spring pin started in the hole in the pipe stub, drive it in with the hammer until about 1/4" or so is still exposed.  Now center the left hole in the sliding collar with the hole in the air tube, and install the spring pin in the same manner.
Helpful hints...
*Shovel out the ashes from the firebox before installing the new tubes.  Trying to find a dropped spring pin in the ashes is like trying to find your car keys that you dropped in the snow.
*The holes in the sliding collars are slightly larger than the spring pin holes in the tubes - the spring pin does not fit tightly in the sliding collar holes.
*Note that the spring pins have a slot down one side.  When removing or reinstalling the pins, if you put the jaws of the pliers on either side of the slot and squeeze the slot shut, it will slide in or out a little bit easier.  You may need to use the vice-grips to get enough force to close the slot in the spring pin.
*If you have to punch the old spring pin up into the pipe stub, it can be retrieved with long-nose pliers.  Or, you can just push it into the secondary air duct, where it will lay harmlessly for the life of the stove.
*If you wear bifocals like I do, you may find it helpful to lay crossways in front of the stove (on you left shoulder, if you are right-handed) to do the work.  Disregard this helpful hint if you can tip your head way farther back than I can, in order to focus properly!
