you use the word Country? may i ask which one you mean? many of us are in the USA where codes might be way different than where you are
The county I live in insist a standby generator MUST be a minamum of 5 feet away from any construction, period. When I point out the generator I would like to install is approved for 18" from non-combustable construction, they give me no recourse to appeal the rule. They would not even consider 24" space between the generator and a stone wall.
I would be interested if anyone has been successful perswading their building inspector to reconsider a 5 foot rule?
