3 INTRODUCTION
3.1 DESIGN & OPERATION
The Gabarron MATTIRA COMBI boilers are
electrically heated combi boilers providing wet central
heating through a standard radiator system (or
underfloor system with special kit) and domestic hot
water (DHW) delivered from an integral unvented
store at mains water pressure.
Outputs are from 2 to 15kW. Maximum output can be
adjusted to match the heat requirement of the system
or the limitations of the incoming available power
supply. Operation is possible on three phase
N or single phase 230V - 50Hz.
The boilers are designed for internal installation on a
suitable wall with consideration for the total weight of
the appliance when full.
A digital control panel provides user control to adjust
the temperatures of heating and hot water. A power
modulation feature automatically adjusts the heating
output to the demand to ensure economic operation.
A suitable external time clock/room
thermostat should be fitted (not supplied).
An adjustable thermostatic blending valve
should be fitted on the hot water supply to
ensure a safe and economic supply of hot
water (not supplied).
