Verify that the chosen HIVE Heat wood-burning stove model complies with the dimensions of your sauna room. Nominal heating power (kW) of the sauna stove must be in accordance with 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.
HIVE Heat is suitable for sauna rooms sized 212 – 459 ft³ / 6–13 m³.
Verify that the cross-section of the chimney flue is at least 0.1 ft² / 102 cm2.
The minimal safety distance between the ceiling and the walls of the steam room and flammable materials are presented in Table 1.
Installation of the sauna stove
Mounting of the sauna stove must conform to all local normative documents, including relevant national standards concerning installation.
Before installing the sauna stove, check the safety distances provided in Table 1. Safety distances A, B and 47.3 in / 1200 mm above the sauna stove apply to flammable materials.
If the stove is installed in a niche made of non-combustible material (stone, concrete), at least 4 in /100 mm should be left between the wall and the stove for air movement.
Safety distance from flammable materials may be reduced to 1/2 when a single heat barrier (heat reflector) is used and to 1/4 in the case of a double heat barrier. Heat barrier is included within the safety distance, and clearance between its outer surface and the protected area must be at least 1.2 in/30 mm.
Install the sauna stove on a non-combustible surface that has sufficient load-bearing capacity.
There should be no electrical devices, wires, or cords in the safety area of the sauna stove.

The furnace bushing of the sauna stove must be made through a non-combustible wall (stone, concrete, etc.).
In addition, it is recommendable to use insulation with mineral wool or a similar material.
The furnace bushing of the sauna stove must be made through a non-combustible wall (stone, concrete, etc.) that extends 600
mm / 23.63 in to the sides of and 1 400 mm / 55.1 in above the opening.
Leave at least 2 in/50 mm between the bushing and the stove for air movement. When calculating the dimensions of the opening, add 4 in/100 mm to the height D and width C provided in Table 1.
If the floor in front of the furnace is made from combustible material, fire-resistant floor protection (thermal plate) must be installed in front of the furnace door. The protection must be 23.63 in/600 mm wider than door width G, with a depth of at least 15.75 in/400 mm.
Connecting the sauna stove with the chimney flue
The sauna stove must be connected to the chimney flue by a specialist.
The Flue gas outlet is on the top of the sauna stove. The sauna stove is connected to the chimney flue with special metal flue pipes that may be caulked with heat-resistant sealing rope when necessary.
The curves of the elbows of the connection pipes must be smooth in order to minimize draught loss.
The pipe is inserted through the wall of the chimney and then sealed with mineral wool.
The flue gases of the stove must be directed into a separate flue. It is forbidden to use a common flue that is utilized with other furnaces.
Important! Utilization of forced extract ventilation might cause problems with air exchange of the room and insufficiency of furnace combustion air; therefore, designing and constructing such ventilation systems is permitted only on the sole responsibility of a licensed specialist.
Sauna stones with a diameter of 2-4 in /5–10 cm are suitable for HIVE Heat wood-burning stoves. It is recommendable to use round sauna 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.
You can also use granite fieldstones, or other commercially available stones that are specifically meant to be used in sauna stoves. It is not recommended to use ceramic stones in sauna stoves as they break easily and shorten the useful life of the sauna stove.
Quantity of sauna stones
HIVE Heat 12 wood-burning stove requires 198 lb / 90 kg of sauna stones with a diameter of 2-4 in / 5–10 cm.
Installation of sauna accessories of HIVE Heat wood-burning stove
Installation of the thermal plate
Choose the desired location for the thermal plate. When positioning the plate, pay attention to ensuring the safety distances stipulated in the user manual of the sauna stove.
Adjust the height of the legs so that the thermal plate is level and stable and does not sway on the floor. If possible, use a spirit-level.
Place the sauna stove in the center of the thermal plate so that the distance from all sides of the plate is equal.
After placing the sauna stove on the plate, verify again that the safety distances of the sauna stove are proper.
Installation of the heat exchanger (water jacket)
Before mounting the heat exchanger(water jacket), install the HIVE Heat burning stove, but don’t stack it with sauna stones yet. You will need a separate water tank that will be connected to the heat exchanger.
Heat exchanger may be placed at the rear side of the sauna stove, or at one of the lateral sides.
Heat exchanger must be fitted on the triangular frame, tightly against the sauna stove.
When connecting the heat exchanger with the water tank and filling the sauna stove with stones, observe that the water jacket remains snugly against the furnace.
Water tank must be located higher than the pipe connections of the heat exchanger to ensure its proper functioning. The minimum diameter of the water pipe is ¾ inches. Pay attention to the inclinations of the pipe – air bubbles should not get trapped in the circulation.
Important! You can place several cages around the chimney pipe. Use 3 bolts for connecting two cages. The maximum diameter of the bolts is M6, and the minimal length of the threads is 2 in / 14 mm. Choose nuts that are suitable for the bolts.
Use approximately 66 lb / 30 kg of sauna stones with a diameter of 2-4 in / 5–10 cm for filling the stone cage.
Installation of the reflector
Place the reflectoron the collars so that the upper hook of the reflector fits over the upper collar of the stove 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.
