LP-387 REV. 12.15.14
PART 1 – GENERAL SAFETY INFORMATION
A. PRECAUTIONS
This boiler is for indoor installations only. Clearance to combustible materials: 6” top, bottom, and sides, 0” back. Left side has all boiler
mechanical connections. Front must have room for service, 24” recommended. (A combustible door or removable panel is acceptable
front clearance.) This boiler has been approved for closet installation. Do not install this boiler directly on carpeting. For installation on
combustible flooring. Category IV vent systems only.
INSTALLER – Read all instructions in this manual before installing. Perform steps in the order given.
USER – This manual is for use only by a qualified heating installer/service technician. Have this boiler serviced/inspected by a qualified
service technician annually.
FAILURE TO ADHERE TO THE GUIDELINES ON THIS PAGE AND HAVE THIS BOILER SERVICED/INSPECTED ANNUALLY
CAN RESULT IN SUBSTANTIAL PROPERTY DAMAGE, SEVERE PERSONAL INJURY, OR DEATH.
NOTE: When inquiring about service or troubleshooting, reference the model and serial numbers from the boiler rating label.
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.
Be sure to disconnect electrical power before opening boiler cabinet or performing service. Failure to do so could result in an electrical
shock that could result in property damage, serious personal injury, or death.
NOTE: If the boiler is exposed to the following, do not operate until all corrective steps have been made by a qualified serviceman:
1. FIRE
2. DAMAGE
3. WATER
Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee.
Due to the low water content of the boiler, improper sizing of the boiler with regard to heating system load will result in excessive 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.
B. IMPROPER COMBUSTION
C. GAS
Should overheating or gas supply fail to shut off, do not turn off or disconnect electrical supply to the circulator. Instead, shut off the gas
supply at a location external to the boiler.
D. WHEN SERVICING THE BOILER
To avoid electric shock, disconnect electrical supply before performing maintenance.
To avoid severe burns, allow boiler to cool.
E. BOILER SYSTEM
Thoroughly flush the system (without boiler connected) to remove sediment. The high-efficiency heat exchanger can be
damaged by build-up or corrosion due to sediment. HTP recommends a suction strainer in all systems.
Do not obstruct the flow of combustion and ventilating air. Adequate air must be provided for safe operation. Failure to keep the vent
and combustion air intake clear of ice, snow, or other debris could result in property damage, serious personal injury, or death.
