Part 1 - General Safety Information
This boiler is approved for indoor installations only and is not
intended for use as a pool heater. Clearance to combustible
materials: 0” top, bottom, sides, and back. Left side has all
boiler mechanical connections. Boiler must have room for
service: 24” front is minimum recommended service clearance.
(A combustible door or removable panel is acceptable front
clearance.) This boiler has been approved for closet installation
and installation on combustible flooring. Do not install directly on
carpeting. Install the boiler in a location where temperature and
pressure relief valve discharge or a leak will not result in damage
to the surrounding area. If such a location is not available, install
an auxiliary catch pan. Use only Category IV vent systems.
Installer -
Read all instructions in this manual before installing.
Perform steps in the given order.
User -
This manual is for use only by a qualified heating installer /
service technician. Have this boiler serviced / inspected annually
by a qualified service technician.
FAILURE TO ADHERE TO THE GUIDELINES ON THIS PAGE
CAN RESULT IN SUBSTANTIAL PROPERTY DAMAGE,
SEVERE PERSONAL INJURY, OR DEATH.
NOTE:
If the boiler is exposed to the following, do not operate.
Immediately call a qualified service technician.
1. Fire
2. Damage
3. Water
Failure to follow this information could result in property
damage, severe personal injury, or death.
DO NOT USE THIS BOILER IF ANY PART HAS BEEN
SUBMERGED IN WATER.
Immediately call a qualified
service technician. The boiler MUST BE replaced if it has been
submerged. Attempting to operate a boiler that has been
submerged could create numerous harmful conditions, such as
a potential gas leakage causing a fire and/or explosion, or the
release of mold, bacteria, or other harmful particulates into
the air. Operating a previously submerged boiler could result in
property damage, severe personal injury, or death.
NOTE:
Boiler damage due to flood or submersion is considered
an Act of God, and IS NOT covered under product warranty.
