Posted by Don Squire - Hawken Energy Outdoor Wood Furnaces. Now, loop each copper end around each terminal, and tighten the screw on the terminal. The figure below is for outside foot dimensions. You may get yourself in so much trouble that you will have to call a professional. Broken shafts are not covered under warranty unless found and noted before outdoor wood stove installation and startup. There is nothing wrong about using auxiliary relays to control the two heating sources.
Probably simpler to use a single relay to the hot water system and control voltage from the air handler. Once all piping connections are complete, flush about 20 gallons of water into the float stack and drain, repeating until it comes out clean. I found the wiring diagrham on the Central Boiler web site. The mechanical thermostat is very good thermostat because it is pretty much impervious to power surges but a better one is needed in these applications. With that being said, here is my question.
The idea of isolation relays is beginning to make some sense now. Many systems only have a single compressor but if you have two compressors which should only operate off of one thermostat then you need the Y2 thermostat terminal for second stage cooling. The ground temperature below the frost line is 50-55 degrees, even in winter, so heat loss is minimal. Most installers use the color coding as noted but be aware that some do not use the thermostat color coding. For the tank part I used an old fuel oil tank. No more worries about frozen water! This is normal and will occur anytime too much water has been added. On a final note, the venstar thermostat will eventually be replaced with a different thermostat.
It has two forced air draft fans with automatic dampers on them. I ran the first one of these all last winter with no problems at all. I did that with the heater I made from an old gas furnace for the garage. This may raise the water temperature to way over 200 degrees. If it ever falls below 120, the indoor burner will fire again to keep the home warm and also reverse heat the outdoor boiler to keep it from freezing. Never cover the underground ducts and wiring before an inspection, if even needed! But, in the long term, the Venstar unit will be replaced with a Crestron unit. For this, I welded a small pipe fitting in a convenient spot and installed an air valve.
Powering the G terminal on a variable speed fan will not bring the fan up to full speed. See maintenance section for complete adjustment and care instructions. You will need to unscrew that and screw the dry well in its place, using Teflon tape. If you are putting this in an outbuilding as I did, you can wrap it with fiberglass insulation and you are basically done. Use the wire cutters to strip each wire so that there is approximately 1 inch of bare copper showing. Everything is very simple and easy to do. The extra outlet will provide a total of 10amps for convenience use.
One of them will have control voltage at all times, the other will have it only when you have selected Fan-On. In the past, boiler-thermostat wiring used to be rated for 110 volts, but now modern systems are rated for 24 volts. While test fitting try to determine how much tape is needed around the frame of the heat exchanger to seal and keep air from flowing around it. Most installers use the color coding as noted but be aware that some do not use the thermostat color coding. Use the wire snake to pull the wire through closed walls and into your attic or basement depending on the type of home you are working in.
This wire should go directly to the heating source whether it be a gas or oil furnace, electric furnace, or boiler, White for W Terminal. Any higher than this and hot water may push the float out and also cause scalding water to spill out. The water level will rise and fall during operation as water expands and contracts with temperature changes. Slide the heat exchanger carefully into the plenum to check the fit again. For a hydronic radiant system, reverse this order.
If you set your regular furnace thermostat a bit lower than our auxillary themostat, you will have that as a backup. For this reason, it is a good idea to kill the power at the condenser and the air handler before changing or working on the wiring at the thermostat. I dont recommend a drum for the firebox. No boilers or radiant floor heating systems can be hooked up. I do not have a zone valve but would say you could use the G fan output of your single stage thermostat to open your zone valve.
