J. Wall-Mounting (Wall Mount Models Only)
The boiler may be installed on any suitable internal wall (suitable sound-proong may be required when installing onto a stud partition wall).
The boiler must be installed on a wall that can bear its weight (more than 110 lbs. when fully plumbed and full of water). Installing the boiler
on a wall which cannot support its weight could result in property damage, personal injury, or death.
