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: 6”
top, bottom, sides, and 0” 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 the boiler over a drain 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.
NOTE:
Obey all local codes. Obtain all applicable permits before
installing the boiler.
NOTE: Install all system components and piping in such a manner
that does not reduce the performance of any fire rated assembly.
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.
Altering any HTP boiler with parts not manufactured by HTP WILL
INSTANTLY VOID the boiler warranty and could result in property
damage, personal injury, or death.
