SAWO Dragonfire DRF3-90NS [11/20] Heater stones

Heater Stones

NOTE! Never use the heater without stones as it may cause fire. Use

only manufacturer recommended SaWo-stones. Using unsuitable

stones may lead to heating element damage and will void the

warranty. Never use eramic stones or other artificial stones of any

type!

The main purpose of the stones in the heater unit is to store enough energy to

efficiently vaporize the water thrown on top of the stones to maintain correct

humidity in the sauna room. The stones must be removed at least once a year

or every 500 hours which ever occurs first. All stone crumbles must be

removed from the heater unit and replaced with new ones as described in the

heater manual. The required amount of stones is also listed in the manual

provided. See page 18 (Technical Data).

Loading stones into the heater

It is recommended that all stones should be rinsed to remove any stains or dust

that can cause unpleasant odor during the first few times of using the heater. It

is important that the stones are loaded carefully in a way that they do not block

air circulation through the heater. Load the stones to the heater so that the

heating elements are not visible from any angle. Make sure that the elements

don’t get bended or touch each other as a result of the loading by properly

installing the heating element spacer. Larger stones that won’t fit between the

heating elements must not be forced in place instead they must be completely

removed. Small crumble or stone pieces smaller than 35mm in diameter must

not be loaded into the heater because they will block the air circulation and will

cause overheating and possible heating element damage. Use the three

addtional heating element separator to make sure that heating elements are in

no contact with each other. Do not place stones inside the heating element

holder, but only around and on top of it. If heating elements touch each others,

it will significantly reduce the life span of heating element.(fig.4) Do not lay

stones on top of the heaters collar. It will block the ventilation and causes a fire

hazard.

NOTE! Heating element damage due to overheating caused by

wrong kind of stones or stones which were wrongly loaded into the

heater is not covered by the factory warranty.

Before the heater is filled with stones, electrician should test that the

heater works. Testing can be done by turning on the heater for a

short time without any stones and verifying that all heating elements

are heating up.
