INSTALLATION AND ASSEMBLY

Warning
- Observe current Regulations.
- Size and design the chimney for the LAIA GTA, GTAX & GTAF Heating Units in
compliance with current local Regulations for Heating Systems in Buildings
which apply.
- The installation should include a switch, a circuit breaker or other omnipolar
disconnect switch to isolate all power supply lines to the Heating Unit.
- Ensure there is a 230V-50Hz single-phase, earthed power point as well as a
water supply and drain facility near the installation site of the unit.
- When fitting approved chimneys, please observe the manufacturer's specifications.
- To remove possible residue from the chimney, it is advisable to have a handhole
at the base for this purpose.
Location
As a rule, the location should be chosen according to conditions such as access
of fuel, flue gas removal, ventilation, drain, etc.
Always check that the boiler is level on its chosen installation base and that there
is sufficient clearance from surrounding walls to permit future maintenance
operations.
