Unpacking

RISK ASSESSMENT - Before commencing the
installation it is recommended that the 'Five Steps to
Risk Assessment' document published by the HSE is
consulted, and an assessment performed as described.
GAS SUPPLY - The gas supply, gas type and pressure
must be checked for suitability before connection.
1. See 'Section 2.3.1 Handling' before unpacking or lifting the
boiler.
2. Follow the procedure on the carton to unpack the boiler or see
Fig. 14a.
3. If pre-plumbing (Fig. 14) - the wall jig and fitting kit can be
removed without removing the carton sleeve. Simply slide
banding to the edge and open the perforated flap, lift out the jig,
fitting kit and instructions. If the boiler is to be install at a later
date, close the flap and reposition the banding straps, the boiler
can now be store safely away.
A small amount of water may drain from the boiler in the
upright position.
