•
Due care should be taken when lifting the
boilers, with respect to their weights, see
Table 2 on Page 6. Also refer to Section 1.4
Safe Handling.
1. Lift the boiler onto the wall mounting plate as
shown. Note: It is not necessary to hold the
boiler at an angle to engage the wall mounting
plate.
2. Using the remaining coach screws, secure
the bottom of the boiler to the wall through the
attached brackets.
IMPORTANT NOTE It is essential that these bolts
be fitted prior to making up the flow and return
connections to the boiler to prevent the boiler
becoming detached .
