• A drain cock should be installed at the lowest point in the heating system to allow the water in the
heating system to be drained as fully as possible.
• While the boiler and heating system may be filled from the cold mains water supply, the boiler
must be isolated from the cold mains water supply by a suitable break in the supply pipe during
normal operation.
• Filling Loop- this boiler is not fitted with a filling loop. Any filling loop being fitted should comply
with the water supply (water fittings) regulations 1999 Section G24.1 and G24.2. A filling loop
should be fitted at some point to allow the CH system to be filled.
• The boiler must be installed in an upright position away from nearby objects (see installation
section for clearances) in a clean, dry, frost free place.
