General Information

Installation
  • We recommend having your professional heating and air contractor install your furnace.
  • You can dig the line, lay the pipes, etc. Follow guide lines in the owner's manual.
  • You do not have to have a poured concrete pad to set this furnace on. You may set it level on solid concrete blocks or pour a pad, whichever you like.
  • Know your local building codes, wiring codes and restrictions.
  • If you wish to pour a concrete pad make it 5' x 8' & 4" to 6" thick.
  • Insert a 5" to 6" PVC pipe up through the concrete, coming up in the rear door work area, preferably on one side, at a 45 degree angle for ease of water pipe entrance to the hook-up area.
  • Dig a 24" to 36" deep line or deeper in extreem northern sites.
  • You can use factory Pex pipe or build your own system using Pex line, insulation & 4" heavy PVC. 
  • In this ditch line, run your electric and water source line along with your Pex loop lines. Do it to local code or better.
  • Pump: You can discuss with your installer or us which pump brand you want. It can be placed in your home, or at the back of the Earth Furnace. We recommend a pump that runs 24-7. If you are over 50 ft. from your house, you may want to consider 1" water pipes that carry more volume, and a larger pump than normal, especially if you are over 100 ft. and if you are pumping water up an incline.
  • Return Line: Your outgoing line is a little over half way up, on the left as you stand looking at the rear service panel. Your return line is on the right side, at the bottom. This return line port takes the returning de-heated water to the front for a true mix before it is taken out again.
  • You can go through or under the foundation with your Pex line, into your existing furnace area.
  • Your heat exchanger shoud be duct worked just beyond the exisitng fan, so that it  blows heat through the existing ducts into your home. If you do not have a duct system, you can pipe directly into a radiant floor system or simply blow direct with a fan.

 

What Size Furnace Do I Need? 

  • BTU usage is the critical factor.
  • Example: If you are using (1) 20"x20" coil, that is 140,000 BTU + Domestic Hot Water Heat Exchanger that is 80,000 BTU, then you need a 220,000 BTU furnace
  • At this point you are nearly at normal max on a Rancher 360 or 365.
  • Don't under-size yourself. Better to have a little extra than too small.
  • Talk to your dealer, or our factory, and do an estimate on your BTU usage before you order.

 

Heating Your Hot Water 

  • Your furnace is capable of heating your hot water for your home. We suggest one of these two methods.

        1. Order your furnace with a copper coil on the inside to which you hook 
             your hot water line. 
                                                OR

        2. Install a separate heat exchanger near your hot water heater in
             your house. 

Servicing Your Furnace

  • Periodically (once a month or so) clean the chimney pipe. The Earth Furnace does not have "elbow" or angle areas to collect condensation or rust out. Cleaning is very simple. Use a rod with a 4" flat round piece welded on to drop down the pipe. One or two up and downs and your done! 
  • Watch your ash pan. Usually once per week clean out will do. Not cleaning the ash pan will hinder your air flow from underneath. Use a regular flat shovel turned upside down for quick clean out.
  • Check your water level once or twice a week. It's easy! Turn the valve above your furnace door to "on". It will quickly fill and run out the side overflow; then turn to "off".

Opening Your Furnace Door

  • Your furnace is equipped a double latch safety system and 18" handle. When opening the door the latches will "catch" before completely opening.
  • If you burn only regular wood, you should never have any "blow back" when you open the door.
  • It is unlikely in the Earth Furnace to ever have "blow back"... but it is always wise and prudent on any type of furnace to be aware of any potential and use reasonable care when opening.
  • Always keep your facial area away from or close to the door area. That fire is hot! Sometimes a rush of air on a simmering furnace can cause pretty quick combustion. Always use care.

Only Burn Approved Materials

  • Caution! Never burn un-approved materials. First, it negates your warranty.
  • Second, there could be substances that could cause combustion, or otherwise damage to persons, property, or the furnace.

What Can Tear Up, Wear Out, Or Break Down

  • The Earth Furnace is designed to last well beyond the purchasers life! We hope your grandchildren can use it.
  • There is really not much that can go wrong with the furnace; fans, thermometer, pumps, light switch. But that's about all.
  • You have factory warranty on thermostats, pumps, etc. Your warranty on everything from the connections to your house & buildings and in them is between you and your installation contractor.
  • In the very rare occasion of a water leak, we will either send a repairman, or replace the furnace. Note: There can and will occasionally be water condensation in the door frame. This is from high moisture wood, or the furnace running at low temperature. It is not a leak!
  • If your furnace does not seem to be working satisfactorily... First visit with your installation contractor. Then, if it is not resolved, and you really believe the problem is with the furnace, call us or have your contractor call and we'll help every way we can.

Custom Furnace Colors

  • It's nice to match your current buildings, but consider that you will have smoke from both the door and chimney that will be a factor over time. Darker colors usually work out for the better. Standard colors are emerald green, dark brown, charcoal gray and country red.

Furnace Covering Ideas

  • Your furnace will come with a corrugated metal covering. You can order flat metal covering too. Pick your colors!
  • You can add brick or rock, or otherwise appropriate type siding to match your existing buildings.
  • Our covering makes our furnaces snug against the 2" dense insulation board and makes for a super tight box. And as mentioned above makes it easy to brick or rock, or use appropriate siding for matching.

Receiving and Unloading Your Delivered Furnace

  • It can be lifted by forks from underneath...BUT!... use care! We recommend using 2"x6" lumber between the forks and the furnace. Make sure the forks are under both sides of the furnace angle iron. DO NOT puncture the bottom with careless handling! Also, use a ratchet strap to hold the furnace to the loader unit while moving and use something to pad between the furnace and the loader fork back to prevent from scratching or other damage. Handle it slowly and carefully and keep people away! This furnace is heavy and could crush someone if it fell off in moving.

What Comes With Your Earth Furnace

  • Automatic damper
  • Water Filled Valve System
  • Exterior Light
  • Customized total packages available with heat exchanger, water pump, Pex line, and ball valves.

How The Furnace Works     

 

  • The firebox is surrounded by water.
  • That hot water is pumped (by a small pump located either on your furnace or in your house) through a pipe loop to the heat exchanger in front of your blower fan.
  • The blower fan blows the radiated heat from the hot water into your duct system, into your home for clean, non-dry, even, comfortable heat.
  • The "heat-reduced" water returns to your furnace, is re-mixed with the "hot" water, and continues the circle, providing you with consistent, clean, efficient heat that won't dry out you, or your home!
  • You can utilize your existing blower, duct work, and house thermostat!

Burn Time - Facts & Fiction

  • "Burn Time" is a term used to gauge the time your furnace will operate before re-loading it with wood.
  • Be very careful about deceptive "Burn Time" advertising!
  • The Facts: "Burn Time" is affected by several factors:

        (1) How many square feet are you heating?
        (2) Daily temperature variations & fluctuations.
        (3) Type of water system (Pex) you install.
        (4) Distance from the furnace to the home.
        (5) Incline of water flow.
        (6) Type of wood and amount of moisture in the wood you are burning.

        (7) Insulation quality and value of the house or building.

  • The Truth is... most furnaces, you will have 12-18 hours burn in average conditions, so figure on putting wood in morning & evening. If you have your furnace in a handy location like I do, I fill it before I get in my truck to leave and fill it when I get home before I go in for the evening. In severe cold and wind chill weather, you may need to fill before going to bed at night.
  • These are the facts & truth. The main thing is... make it handy. Enjoy your furnace. Save money! Keep your home cleaner & safer! Enjoy that consistent, even, steady comfort & warmth, & smile when you want to turn the thermostat up!
