3. Install two set screws through the bracket at the
bottom of the boiler to secure the boiler on the
wall.
WARNING
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.
Install the boiler in the upright, vertical
●
position. Installation in any other orientation
will result in improper boiler operation and
property damage, and could result in serious
personal injury or death.
NOTICE
Ensure that the structure of the installation
●
location is sturdy enough to support the full
weight of the installed boiler, including the
water contained in the heat exchanger and
related piping.
The wall must be vertical, and it must be
●
capable of carrying the weight of the boiler.
Do not mount the boiler to drywall that has
●
not been reinforced.
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.
