6 APPLICATION DATA

The Gas 310/610 ECO can be used on all new and retrofit projects in both single and multiple
configurations. Conventional and sealed combustion venting system capability means that the boiler can
be sited almost any-where within a building.
External control systems (BMS) can be interfaced with the boiler to provide on/off – high/low or
modulating (0-10 V dc input) firing control options.

7.2 Delivery and installation

The De Dietrich Gas 310/610 ECO is supplied fully assembled, plastic wrapped and crated on a pallet.
The overall dimensions of the crate are 31.5" [80cm] wide and 68.9" [175 cm] high with the length
dependent on the number of sections (5 & 6 sections: 66.9" [170 cm], 7 to 9 sections: 82.3" [209 cm]).
At the base of the packaging is a 30" [76 cm] wide pallet enabling it to be transported with a pallet truck,
forklift truck or 4-wheel transport boards. Excluding the crate, the boiler is 28.4" [72cm] wide c/w casing
panels and 27 5/8" [70 cm] without casing and will fit through most standard doors (minimum door
opening width 31.5" [80 cm]. The boiler itself has wheels so that, once the packaging has been removed,
it can easily be moved around on a smooth surface. The packaging lid includes a rocking ramp, which
can be used to negotiate obstacles such as doorsteps and small plinths. Once in position the boiler is
fixed into position using the fitted jacking bolts which both raise the wheels of the ground and level the
boiler. Technical documentation is supplied in a holder on the inside of the boiler casing (beneath the
instrument panel). A number of small loose components, such as the 4 support pads and the siphon for
the boiler have been placed in the flue gas discharge.
The Gas 610 ECO boilers consist of a Gas 310-L and a Gas 310-R. Please refer to page 11 for
