PART III: OPERATION

Gas valveversion with SKP2 (built-in pressure stabilizer)

To increase or decrease gas pressure, and therefore gas flow rate, remove the cap

T

and use

a screwdriver to adjust the regulating screw

VR

. Turn clockwise to increase the flow rate,

counterclockwise to reduce it.

Adjusting the gas valves group

Multibloc MB-DLE

The multibloc unit is a compact unit consisting of two valves, gas pressure switch, pres-
sure stabilizer and gas filter.
The valve is adjusted by means of the

RP

regulator after slackening the locking screw

VB

by a number of turns. By unscrewing the regulator

RP

the valve opens, screwing the valve

closes. To set the fast opening remove cover

T

, reverse it upside down and use it as a tool

to rotate screw

VR

. Clockwise rotation reduces start flow rate, anticlockwise rotation incre-

ases it.
Do not use a screwdriver on the screw

VR

!

The pressure stabilizer is adjusted by operating the screw

VS

located under the cover

C

.

By screwing down the pressure is increased and by unscrewing it is reduced.
Note: the screw

VSB

must be removed only in case of replacemente of the coil.
