DO NOT store ammable or combustible materials near this
boiler. DO NOT use spray paint, hair spray, or any other ammable
sprays near the boiler or near the exterior fresh air intake pipe
termination. DO NOT place any items in or around the exterior
exhaust vent termination and/or fresh air intake pipe that could
restrict or block the ow in or out of the vent system.
All safety devices must be tested by the installer / qualied service
technician after the boiler is installed.
Always verify proper boiler operation with the qualied service
technician after servicing.
The gas ignition system components must be protected from water
(dripping, spraying, rain, etc.) during boiler operation and service
(circulator replacement, condensate trap, control replacement, etc.)
This boiler features a factory installed overheating prevention device.
This limit will shut down the boiler in the event that the boiler water
temperature exceeds the set point of the limit control. Certain local
codes require additional water temperature limiting devices.
Call a qualied service technician if repair of the gas pipeline or
replacement of the gas regulator is necessary.
Exhaust gas entering the living space can cause carbon monoxide
poisoning. If exhaust gas should leak into the living space:
• Shut down the boiler.
• Close the gas valve.
• Open windows for ventilation.
Immediately call a qualied service technician to inspect the boiler
and exhaust vent pipe. Any damages to the exhaust vent pipe
should be repaired immediately.
DO NOT shut o the boiler for long periods of time during
potentially freezing conditions. If the boiler must be shut o
during potentially freezing conditions (is not to be used for an
extended period of time), shut down the system and drain it of
water. Shut o the gas and cold water supply valves.
Ensure exposed water pipes are thermally insulated to prevent
damage due to freezing conditions. If the boiler is not to be used
for an extended period of time during freezing conditions, shut
down the system and completely drain the boiler.
If the water pipes should freeze, thaw the pipes with a hair dryer or
other electric heating device. If this does not work, call a qualied
service technician.
DO NOT touch the exhaust vent or hot water pipes during boiler
operation.
A. Before Operating the Boiler
1. Check the Gas Type
When operating the boiler for the rst time, ensure the connected
gas type matches the boiler gas type. HTP boilers are factory set
to operate on Natural Gas. BEFORE OPERATING WITH PROPANE
the boiler must be converted to Propane operation by a qualied
service technician, using the conversion kit specic to the boiler
model.
2. Check the Power (120V / 60 Hz)
Ensure the boiler is connected to a properly rated power supply.
Attempting to operate this boiler on Propane when it has not been
correctly converted to Propane operation will result in improper
boiler operation resulting in property damage, personal injury, or
death.
3. Check the Automatic Feed Valve
Ensure the automatic feed valve to the boiler is providing the
proper pressure to the central heating (CH) loop.
4. Check the Gas Shut-O Valve
Ensure the manual gas shut-o valve is open. The boiler will not
operate unless it is supplied with gas.
Failure to connect the boiler to the properly rated power supply
described above (120V / 60Hz) could result in property damage,
personal injury, or death.
It is the user’s responsibility to know the location of the gas shut-o
valve and how to operate it. Immediately close the gas shut-o valve
if the boiler is subjected to re, overheating, ood, physical damage,
or any other damaging condition that might aect the operation of
the unit. Have the boiler checked by a qualied technician before
resuming operation.
5. Check the area around the boiler.
Remove any combustible or ammable materials from the area
around the boiler and do not hang anything from the exhaust vent
pipe.
Do not operate the boiler if its combustion air intake is located
in or near one of the areas or in the vicinity of products listed in
Table 1. These areas will always contain hazardous contaminants
that can form strong acids while passing through the burner and
vent system. These acids will corrode the boiler’s heat exchanger,
burner components and vent system, resulting in ue gas spillage
and/or water leakage, possible substantial property damage,
severe personal injury, or death. If the boiler combustion air intake
is located in any area likely to cause or contain contamination, or
if products which would contaminate the air cannot be removed,
the intake must be re-piped and terminated to another location.
DO NOT re-pipe ventilation system on your own. Call a qualied
service provider for assistance.
B. Primary Water
• Do not attempt to clean the heating system. Call a qualied
service technician for service.
• If you notice any leaks, immediately call a qualied service
technician. Leaks in boiler or piping must be repaired at once.
Closed loops that use glycol as heat transfer uid must be serviced
periodically. Glycol can break down over time, become acidic,
and attack gaskets and seals in boilers. This can result in property
damage, severe personal injury, or death.
Each glycol manufacturer has dierent recommendations for
testing and replacement. Do not test glycol quality yourself. Have
your qualied service technician check glycol quality during
annual servicing. If you are unsure when your glycol was last
tested, call a qualied service technician to test and replace glycol,
if necessary.
C. Freeze Protection
D. Combustion Air Contamination Prevention
DO NOT attempt to install, repair, or service this boiler. Contact a
qualied technician if the boiler needs repair or maintenance. Ask
your gas supplier for a list of qualied service providers.
DO NOT attempt to disassemble this boiler. If repairs are required,
contact a qualied service technician.
