18 Installing the Boiler
WARNING
Ɣ The boiler is heavy. Always lift the unit with assistance. Be
careful not to drop the boiler while lifting or handling it to
avoid bodily injury or damage to the unit. It is recommended
to use a lifting device when lifting the product. The
maximum load of the device should be based on the weight
of the appliance with water.
Ɣ
Do not rest the boiler on the bottom end after removing it
from the shipping carton. Doing so may result in excessive
pressure on protruding pipes and resulting in product
damage. If you must put the boiler down, lay it on its back or
put it inside the protective shipping base.
Ɣ
If a separate installation structure is provided, it must be
fixed on the floor with a stud.
Ɣ Make sure that the wall bracket is installed horizontally
using a spirit level.
Ɣ
Be careful not to drop any foreign objects into the intake or
exhaust vents during installation.
CAUTION
Do not mount the boiler to drywall that has not been
reinforced.
