That is a great idea, you should be able to sell that one for enough money to fund the cost of a new propane unit.

140,000 BTU is the smallest. I would get some bids for propane and see what you would be looking at for costs.

I would not go smaller than 45,000 BTU or larger than 60,000 BTU. Both of those can be purchased for well under $1,000. A new CB-140 is going to run you $4,950 maybe cheaper if your dist is running any kind specials. That is a big price gap for a shop that only gets occasional use.

If you were my customer I would try to talk you out of buying a heater. I believe in being honest with customers is more important that making a couple of $$. For that small of shop I would go with NG/Propane or even electric depending on rates in your area. 

What is the height of your shop and level of insulation ? Lets try to narrow down your BTU # and see what would work best for you.

36x28 is that a misprint ? If not that is going to play a big part in the formation of rust on the firebox. I am going to ballpark your BTU needs @ 60,000 or less and your heater is 185,000 BTU. That much overkill is not good for fireboxes.

A new CB-140 @ 140,000 will be a little closer to your needs but still overkill. Size wise it is only about 12" longer and HxW are similar. Much easier to clean to with the swing away door. Metered oil pump so you never have to adjust oil pressure again.

Hello Jerry,
                 That is something that happens with fireboxes over time. They will eventually rust out  and need replacement. I would clean the heater then remove the fan and sheet metal top of heater. Do a visual inspection to check for cracks and holes in firebox/tubes. I then hit each tube with a hammer to make sure each one rings and if you get a thud that tube is bad.

27 years is a very good lifespan for a firebox. Unfortunately it was discontinued several years and there is no replacement fireboxes. The new style burners and fireboxes are a huge improvement you might want to check out.

If there is anything I can do help let me know.

If no one has a manual take some pics and we can get it figured out.

Waste Motor Oil / Re: Oil not igniting
« on: February 14, 2017, 07:08:15 pm »
Water goes to the bottom of tank so it can be easily drained. Your pickup screen should be at least a couple of inches off the bottom.

The nozzle comes apart and there is 3 pieces. Hold it upright with a pair of pliers on the stem and unscrew the top with your 5/8". Spray out the 3 pieces with brake clean onto a paper towel to see if anything comes out. If black carbon pieces come out you need to do a burner rebuild. Clean burn recommends burner rebuilds every year and I say every 2-3 years is good as long as the power is turned off in the Summer.

Waste oil does not need continuous spark. The latest primary controls on commercial waste oil heaters actually turn off the ignitor when cad cell sees flame.

Sounds like you are sucking air.

That heater had like a 77" long firebox. I think a better option would be a Shenandoah B5 burner with J-pump. That way you could dial in the flame perfect for your size firebox.

They epoxy the heating element into the preheat block forcing you to buy the entire assembly. What size heater did the burner/pump come off of ? With that short firebox you might over fire big time since that is a metered pump.

Sparkles could be a variety of things. Water/anti-freeze will usually throw out big sparkles. Smaller ones could be lean from to much compressed air/combustion air or not enough oil. Also make sure both heating elements are working good.

Air 12-14 psi ?

What color is the flame ? Should be bright yellow with orange tips.

Waste Motor Oil / Re: synthetic mix 50/50?

Hydraulic oil will not help. You are going to have to mix it since there is no way to adjust preheat temp on a EnergyLogic.
