Before installing the HIVE Mini electric sauna heater, verify that the maximum amperage of the main circuit breaker complies with the parameters of the heater.
Ensure that the power rating (kW) of the heater matches the cubic size (ft³) of the steam room. In case there are any uninsulated brick, tile, or glass walls in the sauna room, an additional volume of 4,8 ft³ must be added to the sauna room for each 1 ft² of such wall.
The minimal safety distance from the ceiling and the walls of the steam room that apply to positioning of the electric sauna heater are presented in Table 1.
Installation of the HIVE Mini electric sauna heater
When choosing a suitable location, ensure that you can conveniently throw water on sauna stones when sitting on the sauna bench.
Observe that the location of the heater would not create hazardous situations during its use. Make sure that people would not have to pass too closely by the hot heater.
Table 1 gives an overview of the minimal safety distance that should remain between the heater and the ceiling and the walls of the steam room.
Power cable inlets are located on the bottom cover of the heater.
Mount the supplied adjustable legs (4 pcs) below the heater.
Connecting the HIVE Mini electric sauna heater to the power supply
Only a certified electrician may connect the heater to the power supply.
The power cable of the heater must meet the requirements of UL 62 in US and CSA 49 in Canada.
It is forbidden to use a PVC-insulated non-heat-resistant cable as the power cable of the heater.
The junction box must be waterproof and located up to 19.7 in (50 cm) from the floor.
It is recommendable to connect the unit to the mains power supply without an earth leakage circuit breaker.
The cross-sectional area of the cable and maximum amperage of the circuit breaker are provided in Table 2 (240V) and Table 3 (208V).

Open the cover of the heater’s electrical box.
Connect the power cable with the terminal board as shown on the circuit diagram.
Close the cover.
Fix the cable to the output part with a cable strap.
Sauna stones with a diameter of 2-4 in (5–10 cm) are suitable for HIVE Mini electric sauna heaters. It is recommendable to use round stones in HUUM sauna heaters. Round stones complement the design of the heaters and provide milder steam. Our product range includes round olivine diabase sauna stones which are sold in packs weighing 33 lb / 15 kg.
Of course, sauna stones from other manufacturers may be used in HUUM sauna heaters, but in such a case it is recommended to choose stones that are specifically meant to be used in sauna heaters and to avoid decorative stones as they may break easily.
Quantity of sauna stones
HIVE Minielectric sauna heater requires 375 lb / 170 kg of sauna stones with a diameter of 2-4 in / 5–10 cm.
HIVE Mini electric sauna heater with air tunnel requires 309 lb / 140 kg of sauna stones with a diameter of 2-4 in / 5–10 cm.
Installation of sauna accessories of HIVE Mini electric sauna heater
Installation of the safety railing of HIVE Mini electric sauna heater
Attach the wooden arcs of the safety railing with screws to the outside part of the bracket.
Install the inner part of the bracket between the upper and the subsequent wire rod of the heater.
Put the inner and outside parts together, and fix them with a bolt and a nut. The safety railing is assembled!
Regular maintenance with a breathable wood preservative helps to extend the useful life of the wooden parts of the safety railing. Use products that are intended for sauna! As a rule, it is sufficient to perform the maintenance once a year, but maintenance interval might be shortened if you use the sauna frequently.
The safety railing of HIVE electric sauna heater is meant to be used only with HUUM electric sauna heaters.
Installation of the embedding flange of HIVE Mini electric sauna heater
The embedding flangeenables one to cover the rims created for mounting the heater.
Maximum extent of embedding the heater into the subsurface is 88 in / 40 cm.
Choose a suitable location for the heater and make an opening with a diameter of 22.9 in / 58.2 cm.
After mounting the heater, place the arcs around the heater to form a solid circle.
Fix the arcs with screws to the corners.
Attach the corners with screws to the subsurface. You’re set to go!
Installation of the reflector of HIVE Mini electric sauna heater
Place the reflector on the collars so that the upper hook of the reflector fits over the upper collar of the heater, and the lower hook goes around the closest collar. Ready!
In case you wish to join several reflectors together, set the external edges of the reflectors against each other, and fasten their upper and lower parts with bolts and nuts.
Installation of the air tunnel of HIVE Mini electric sauna heater
Install the air tunnelbetween the heating elements of the heater.
Remove the cover of the air tunnel.
Stack two layers (approximately 4-5 in) of sauna rocks on the bottom of the tunnel.
Bend the metal retainers under 90 degrees so that they prevent the heating elements from contacting each other.
Put the cover back on.
The air tunnel prolongs the useful life of the heating elements and expedites the heating process.
