Heatmor / Refurbishing older model 400 css
« on: November 23, 2014, 08:46:54 PM »
Had a few questions from anyone out there that has re-worked any of this model of boiler. What type of smoke tube insulation will prevent burn thru of the mild steel 3/16" plate for both tubes? What I removed looked to be waffle shaped with a yellow fiberglass center core and was completely hard as a rock. Was possibly thinking of using 1/4" thick 409 S/S without any insulation or 1400 degree 3/8 high temp glass?? Smoke tubes were both 2/3 full of ash which probably contributed to the burn thru with acidic action?? Also has anyone used firebrick to line the perimeter around the gratebox instead of using masonary sand? Thinking the bricks would hold a lot more heat as a heat sink than sand and would not plug the grating??? Plan on stripping down the exterior sheet metal next spring and checking the insulation and water jacket exterior, top of smoke tubes and welds in general, smoke stack, annode rod, fill/overflow porting. Both acqua stats, temp guage, door gasket & hoses will be replaced and 1/4 turn valves will be added for the door hoses. General cleaning with pressure washer and new high temp. primer and paint job added. Ash box/air tube and fan box seem to be in good shape/some rust-will be cleaned and re-painted-grates are not warped and no cracks-seem to be in excellent shape. Water overflow inner tube was plugged up with some rust and particles-looked to be additive substance-no dry rot-cleaned up and was pressure checked-no leakage. No cresote build up inside to speak of and none on the roof from overflow so stove was in pretty good shape. Would appreciate any pointers from any/all WoodMor owners as I will post more as I move thru this project-not in a big rush as my time frame is over the next two years for a total install.

General Outdoor Furnace Discussion / Heating with OWB fired with high density partical board
« on: April 04, 2014, 06:11:33 PM »
Anyone out there using/have used in the past? Was wondering what type of unit would be able to fire and burn off all the binders used to hold it together? Basically this is pressed sawdust with epoxy binders. Have seen it for sale as cheap as 3500#/$90.00-you have to haul from their mfg. facility. Might be able to mix with good dry oak/maple to get thru those cold days when three loads are needed? Mfgr. claims 8 to 10% moisture content??

Plumbing / Question on SDR9 Pex A
« on: March 25, 2014, 12:05:55 PM »
Newbie here-just trying to get some information about the type of Pex need for my lineset from house to OWB. I have what I call clear(Whitesh color) tubes of 1/2" comming out of the floor-all are marked with the following letters stamped on side--1/2" SDR9 PEX A 100 psi 180 degree F. 180 PSI @ 200 degrees F. also NSF-RFHASTMF876-F-877. Am in process of making a decision on what TYPE & SIZE of Pex would be the BEST type for the lineset run of 100' to boiler & 60' from boiler to garage. Would there be any advantages buying the more $$ Pex-AL or oxygen barrier due to cost for Iron circulators vs SS/Brass? What type of adverse water problems if I run treatment in the system w/anode rod in boiler?? My boiler WJ is 409 SS. Not trying to stump the pro's here-just looking for general information before I make the wrong purchases. I am trying to keep things simple without a lot of bells & whistles. Any and all comments appreciated-Goo-Bad-or-Indifferent. Thanks....Cranky

General Outdoor Furnace Discussion / Newbie here-long time lurker
« on: February 28, 2014, 01:20:15 PM »
Don't know if this is the correct procedure for a introduction--older retired fart here looking to purchase a used(pressure tested) OWB later this winter/early spring. Figured I would start by asking a few questions about how to go about a complete re-furbishment on a older unit? Has any other member here done this? I'm thinking that one should disassemble/inspect all the parts and replace as necessary? From reading many previous posts-a heat assesment of the home and other structures would be in order prior to getting parts or even a quote from a plumber/contractor to install same. This is planed on my part for the forth comming summer time as well as wood gathering and stock pileing. Aforementioned OWB will be a large Woodmor (5-10K) BTU unit of the standard non-gasser type-unknown model # at this point and unknown age. Not trying to throw wet wood in the conversation(Firebox), just would like some informative, constructive vibes/critisimem-good bad or otherwise. Trying to keep this project to a mininum cost factor without breaking the bank. Any comments appreciated
