Pad Preparation:

Pad dimensions for Clean Fire furnaces can be acquired at …..https://woodmastermn.wpenginepowered.com/wp-content/uploads/2021/09/CleanFire-Furnace-Base-and-Dimensions.pdf

Pad Dimensions for Commercial Furnaces can be acquired at…….https://woodmastermn.wpenginepowered.com/wp-content/uploads/2021/09/Traditional-Furnace-Base-Dimensions.pdf

Pad construction can be concrete or 6’ min depth gravel. If using gravel, the material should be contained by pressure treated lumber to mitigate any erosion or wash out. Gravel pads should also be supplied with solid cap blocks for each corner of furnace. If using concrete, a ¾” shim material placed between furnace base and concrete (optional) will keep furnace metal from contacting moisture held on top of concrete. Trex weatherproof decking works ideal for this application. Pad should be level between all corners and have ample access for installation and routine maintenance. If customer is laying insulated tubing prior to our delivery, It is imperative that tubing exits through plumbing notch at 90 degrees (straight up and down) to mitigate kinks which can restrict flow and cause failure.

Trenching:

Trenching between furnace and house wall should be between 12” to 18” deep. If any heavy equipment will be driving over area where tubing is buried, we recommend at least 24” depth. If we are doing a ground set installation, we will need to know this distance in order to bring the correct length of thermopex insulated tubing along. Trench depth should be a min of 36” within 4’ of furnace in order for tubing to flex and exit top of pad at 90 degrees. Otherwise, if tubing exits pad at an angle additional flexible plumbing connections may be necessary.

Electric:

12/2 to 14/2 wire should be supplied from a dedicated 15 amp circuit. If supply is coming from inside house, be sure to allow sufficient connection length to furnace. Wire must be run inside flexible or rigid conduit between house and furnace.

Wall Breach:

The wall breach can be achieved with a core drill or a hammer drill, masonry, bit, and stone chisel

The diameter of the hole should be 3 1/2 “ for residential 25mm Thermopex or 4 ½” for Commercial Thermopex. If you are running elecrtrical conduit through same hole, a masonry bit slightly larger than the conduit size can be used to notch this space. Once Thermopex and/or conduit is installed through breech hole, we recommend it is sealed with caulking and/or mortar cement.
