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.
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.
Altering any HTP, Inc. boiler with parts not manufactured by
HTP, Inc. WILL INSTANTLY VOID the boiler warranty and could
result in property damage, personal injury, or death.
This boiler has been designed to heat potable water ONLY.
Using this boiler to heat non-potable fluid WILL VOID product
warranty, and could result in property damage, personal injury,
or death.
Do not use this boiler for anything other than its intended
purpose (as described in this manual). Doing so could result in
property damage and WILL VOID product warranty.
High heat sources (sources generating heat 100
o F / 37 o C or
greater, such as stove pipes, space heaters, etc.) may damage
plastic components of the boiler as well as plastic vent pipe
materials. Such damages ARE NOT covered by warranty. It is
recommended to keep a minimum clearance of 8” from high
heat sources. Observe heat source manufacturer instructions,
as well as local, state, provincial, and national codes, laws,
regulations and ordinances when installing this boiler and
related components near high heat sources.
A. Improper Combustion
Do not obstruct the flow of combustion and ventilating air.
Adequate air is necessary for safe operation. Failure to keep the
exhaust vent and combustion air intake clear of ice, snow, or
other debris could result in property damage, serious personal
injury, or death.
B. Gas
Should overheating or gas supply fail to shut off, turn off the
manual gas control valve to the boiler.
C. When Servicing the Water Heating System
To avoid electric shock, disconnect electrical supply before
performing maintenance.
NOTE: When inquiring about service or troubleshooting,
reference the model and serial numbers from the boiler rating
label.
To avoid severe burns, allow boiler and associated equipment to
cool before servicing.
Be sure to disconnect electrical power before opening boiler
cabinet or performing service. Failure to do so could result in
electrical shock, property damage, serious personal injury, or
death.

Due to low water content of the boiler, improperly sizing the
boiler in regard to potable water heating load will result in
excessive boiler cycling and accelerated component failure.
HTP DOES NOT warrant failures caused by improperly sized
boiler applications. DO NOT oversize the boiler to the system.
Modular boiler installations greatly reduce the likelihood of
boiler oversizing.
