y

  Since  about  35~45kg  of  weight  will  be  placed,  the  installation  wall  should  be 

reinforced if it lacks the capacity to endure such weight. 

y

  Unit weight is specified in the product specification chart of this manual. 

y

  When installing the unit, use the anchor bolt for firm installation to bear the unit 

weight. 

y

  Fix the unit on the wall firmly to prevent any shaking during its operation. 

(to prevent any noise, it is best to use buffer material such as rubber.) 

y

  Gas boiler is for indoor use only and should not be installed outside such as a 

veranda.
