PROBLEM TO BE SOLVED: To prevent the halfway fire break which occurs when starting plural units of boilers at the same time, in a multiunit installation system for gas stoking boilers. SOLUTION: This multiunit installation system for gas stoking boilers, where a plurality of boilers 1 for controlling the combustion in three positions of high combustion, low combustion, and stoppage are installed and the supply of gas fuel is performed through a common gas fuel supply passage 7, is provided with an operation controller 5 which performs the control of starting the high combustion after going through the starting operation period consisting of an ignition process and a low combustion process, in the case of changing the operation state of the boilers from stoppage to high combustion, and a delay device which starts the combustion of the boilers, leaving an interval equivalent to a waiting time being set to a time over the above flame-stable period, in the case of starting the plural units of boilers at the same time.
