DocumentDocumentbarrel sauna heater setup instructions ATTENTION: All electrical wiring for the sauna must be completed by a certified electrician. Where any Nootka Saunas' instructions and the heater manufacturer's instructions contradict each other, defer to the manufacturer's instructions. As per CSA C22.2 No.164-2018, section 1.2 and section 8.1.3, "factory built sauna rooms where the necessary wiring and heater installation is done in the field", require the heater assembly to carry a CSA C22.2 N0.164-2018, but the room itself is exempt from the directive. The homecraft Heaters that are included with all Nootka Sauna kits carry this label. Having trouble? For questions, comments, or concerns, please reach out to hello@nootkasaunas.ca 01 PART 1: ELECTRICAL TO THE REAR WALL OF THE SAUNA APPROX. TIME REQUIRED: DEPENDS ON SITE SETUP* *Note to Electrician: Please let the client know the estimated cost for the scope of work included in Part 1 and Part 2* PARTS REQUIRED (NOT INCLUDED WITH SAUNA) 1. BREAKER (approximate cost: <$100) The breaker requiring for your sauna depends on the size of heater you ordered. 8ft sauna (6'5" room + porch): Standard 9kW Homecraft heater, required 50A NON GFI Breaker or optional: 7.5kW Homecraft heater, requiring 40A NON GFI Breaker 10ft sauna (8'6" room + porch) 9kW Homecraft heater, requiring 50A NON GFI Breaker 2. WATERPROOF DISCONNECT (approximate cost <$50) Most jurisdictions require a disconnect that is visible and within a certain distance of the sauna. A simple weatherproof, pull bar disconnect is typically suitable. Some electricians will mount these on the rear of the sauna, whereas others will mount the disconnect on a house or nearby structure. 3. WIRING AND FITTINGS (approximate cost: $20/meter + fittings and connectors) From your breaker box to the back of the sauna, Electricians will typically run a 8-2 TECK cable (or equivalent AWCU), as this is armoured and rated for outdoor environments. Most jurisdictions require it to be trenched. For installations under covered areas, provided it's up to code for the area, electricians will sometimes run cable inside of PVC or metal conduit. The Electrician will also need to run the wiring and supply the materials to run power from the 884 PVC junction box that's mounted on the rear of the sauna to the disconnect. NOTE ON TRENCHING YOUR ARMOURED CABLE. Most jurisdictions require the armoured cable to be trenched. Several customers choose to dig their own trench or have a landscaper dig the trench. In this case, it's highly recommended that you consult your Electrician first to ensure that your trench is up to code and that a sensible path for the trench is chosen. ALWAYS CALL BEFORE YOU DIG! Never start digging without first calling your local authorities to ensure there are no gas lines, electrical cables, data lines or other such hazards on your property. This can be a very costly and even dangerous mistake to make.

Run the remaining part of the wire out of the bottom hole from step 1. Strip and carefully connect both the 18/2 and the 18/4 cables to the front display panel. The 18/2 conductors connect to the sensor port (bipolar) Two of the 18/4 conductors (usually red/ black) connect to the 24VAC ports on the controller (bipolar). The remaining two (usually white/grey) conductors on the 18/4 cable connect to the control port. Secure the nylon cable gland that both the 18/2 and 18/4 wires run through.

Flip the heater upside down and remove the 4x self-tapping screws from the bottom of the heater. Use the center rear knockout and mount the supplied TECK connector. Then feed in one end of the supplied 18/2 TECK cable and secure the L1, L2, and GND wires. Use the supplied marrettes for the L1 and L2 connectors and for the GND, use the welded lug.

To mount your stove, fasten the two wall-mount brackets (taped to the stove for shipping) to the back wall of the sauna. The stove will slit into these. To determine the exact positioning for the brackets, position the stove such that the circular punch out on the bottom rear of the stove lines up with the upper hole on the back wall of the sauna. Use a level in the basket of the stove to ensure the stove is level before marking the bracket positioning with a pencil. NOTE: Due to slight variations in the stoves and saunas, we recommend following the above method for positioning the brackets; however, they are generally screwed into the back wall approximately 23 3/4" above the floor and 10 3/8" apart. NOTE: The barrel sauna design, including the above-mentioned heater positioning has been approved by the Homecraft Heaters under their CSA certification (see final page of this package). 06 07 8 mount the junction box to rear wall Ensure that all existing wiring is tight before closing the junction box.

Place each additional layer of rocks across the gaps so there will be good airflow. Stack the rocks loose and high NOT tight and low. We send you more rocks than needed, please do not overload the screen. Keep in mind bad rock placement is the number one cause for the heater to malfunction. Note: Rinse the rocks with water before installing onto the heater screen. view of layered rock placement IMPORTANT BEFORE LEAVING THE SITE, THE ELECTRICIAN SHOULD RUN THE HEATER FOR A FULL CYCLE TO ENSURE THE SAUNA IS FUNCTIONING AS IT PROPERLY SHOULD. - Once turned on, the unit should reach temperature (90C) within 15-20 minutes. - Once the room reaches temperature, the heater should naturally cycle off for a few minutes - After a few minutes the heater will cycle back on This cycle allows the heater to keep the sauna hot, without over-heating the heater components. If the unit doesn't reach temperature in the expected time, or if the heater "trips" (shuts off and won't turn back on), see the troubleshooting instructions below. troubleshooting checklist Troubleshooting must be completed by a certified electrician and in accordance with the manufacturer's recommendations. INITIAL CHECKS Is the incoming power actually 240VAC? We've seen issues before where only ~190V is coming in (one of the legs is compromised) and this ends up giving enough power to sometimes show life on the front control power but not enough power to pull in the contractor). Is the power leaving the transformer in the rear wall junction box 23VAC? (use a multimeter to check) Check that all the 18AWG wires in the rear wall terminal block are secured. Also check that the 18AWG wires in the front control panel are connected and secure. TROUBLESHOOTING CHECKLIST 1 Do you see numbers/display on the front wall control panel? YES: MOVE TO 2 NO: 24VAC isn't getting to the controller. Check the incoming power and make sure the 24VAC labeled 18AWG wires are properly seated/connected into the display and into the terminal blocks on the back wall junction box. Also, ensure that the low voltage wiring hasn't been punctured or damaged during the sauna assembly. For example, a screw through the 18/4 wire will short circuit the output side of the transformer. 2 When you hit ON, does the display show a temperature read out? (the current ambient temperature) YES: MOVE TO 3 NO: It reads OPEN. The temperature sensor wires are disconnected (either where they go into the front wall display panel, or near the ceiling above the heater where they are soldered to the thermistor that's mounted to the wall. Check both for good connection. 3 3. When you hit ON/OFF do you hear a dull thud from the back wall junction box? YES: MOVE TO 4 NO: The contractor isn't getting pulled in. It's very unlikely to have a faulty contractor, more likely that the "control wires" that go back to the contractor from the display control panel are not connected well or are damaged. With a multimeter, check the control wires at various points all the way back to the contractor to see if you're getting 24VAC. 08 09 4 Is there any heat being produced in the sauna after a minute? YES: NO: a) The heater wiring might be loose or not connected properly. Dismount the heater THAT'S GREAT! guard, remove the rocks and flip over the heater to inspect the wiring and ensure a YOU'RE GOOD good connection between L1, L2 and GND. TO GO b) When your sauna heater is overworked the high-limit switch will automatically shut the heater down as a safety measure. On the bottom of every Homecraft Sauna heater you will find CSA approved sticker with our heater information. In the very middle of the aluminum sticker is a hole where the high limit switch is located. Steps to reset the heater: 1. Insert a safe (wooden) object 2. You should hear the sounds 3. Go to your control panel and in the hole and push to re- of the switch re-engaging turn the sauna heater on once engage the high limit again Over-heating at the base will most commonly be caused by the following reasons: 1.
