PART 1 – GENERAL SAFETY INFORMATION
A. PRECAUTIONS
This appliance is for indoor installations only. Clearance to combustible materials: 0” top, bottom, sides and back. Front must have
room for service, 24” recommended. (A combustible door or removable panel is acceptable front clearance.) This appliance has been
approved for closet installation. Do not install this appliance directly on carpeting. This appliance may be installed on combustible
flooring. For use with 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. Refer to user’s information manual for your
reference. 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.
DO NOT USE THIS APPLIANCE IF ANY PART HAS BEEN SUBMERGED IN WATER. Immediately call a qualified service technician.
The appliance MUST BE replaced if it has been submerged. Attempting to operate an appliance 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 appliance could result in property damage, severe personal injury,
or death.
NOTE: Appliance damage due to flood or submersion is considered an Act of God, and IS NOT covered under product warranty.
NOTE: If the boiler is exposed to the following, do not operate until all corrective steps have been made by a qualified serviceman:

FIRE

DAMAGE

WATER
Any claims for damage or shortage in shipment must be filed immediately against the transportation company by the consignee.
Due to low water content of the boiler, improperly sizing the boiler in regard to heating system 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.
B. GAS
Should overheating occur 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 appliance.
C. IMPROPER COMBUSTION
D. WHEN SERVICING THE BOILER

To avoid electric shock, disconnect electrical supply before performing maintenance.

To avoid severe burns, allow boiler to cool before servicing.
E. BOILER OPERATION

Do not block flow of combustion or ventilation air to boiler.

Should overheating occur or gas supply fail to shut off, do not turn off or disconnect electrical supply to circulator. Instead, shut
off the gas supply at a location external to the appliance.

Do not use this boiler if any part has been under water. Immediately call a qualified service technician to inspect the boiler and
replace any part of the control system and any gas control that has been under water.
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.
