Design according to: ANSI Z21.13-2017 CSA 4.9-2017 – Gas-
Fired low pressure hot water boilers. Direct vent boiler, Cat-
egory IV.
− SCAQMD Rule 1146.2
1.3.1 General warnings
9
DANGER: Make sure the gas on which the boiler will operate is
the same type as that specified on the boiler rating plate and
on the colored sticker near the boiler gas connection.
9
WARNING: Should overheating occur or the gas supply valve
fail sto shut off, turn off the manual gas control valve to the
appliance.
9
WARNING: Do not use this boiler if any part has been under
water. Immediately call a qualified service technician to in-
spect the appliance and to replace any part of the control sys-
tem and any gas control which has been under water.
9
WARNING: Automatic filling systems are not recommended
with this product as they will continually add fresh water to
the system if there is a leak resulting in the addition of new
contaminants that could reduce the lifespan of the boiler.
9
WARNING: To minimize the possibility of improper operation,
serious personal injury, fire, or damage to the boiler:
− Always keep the area around the boiler free of combusti-
ble materials, gasoline, and other flammable liquids and
vapors.
− The boiler should never be covered or have any blockage to
the flow of fresh air to the boiler.
9
WARNING: Risk of electrical shock. More than one disconnect
switch may be required to de-energize the equipment before
servicing.
9
WARNING: Failure to comply with the previous warnings could
result in severe personal injury, death or substantial property
damage. Failure to adhere to the guidelines on this page can
result in severe personal injury, death or substantial property
damage.
9
WARNING: Installation and service must be performed by a gas
supplier or a licensed qualified installer/service Technician.
9
CAUTION: This boiler requires forced water circulation when the
burner is operating. See minimum and maximum flow rates.
Severe damage will occur if the boiler is operated without
proper water flow circulation.
9
NOTE: When the boiler has been filled for the first time or the
system has been drained and refilled, it will be necessary to
release any air that may have become trapped within the ap-
pliance heat exchanger. Loosen the bleed screw until water is
released and then close. IMPORTANT, THERE ARE NO OTHER MAN-
UAL AIR RELEASE VALVES LOCATED ON THE APPLIANCE.
The following instructions must be observed
− The boiler must only be used for its designated purpose,
observing the Installation Instructions.
− Only use the boiler in combination and with the accessories
and spare parts listed in the
catalog.
− Other combinations, accessories and consumables must
only be used if they are specifically designed for the in-
tended application and do not affect the system perfor-
mance and the safety requirements.
− Maintenance and repairs must only be carried out by a
qualified service agency at regular intervals.
− You must report the installation of a condensing gas boiler
to the relevant gas and plumbing inspection authority and
have it approved.
− You are only allowed to operate the condensing gas boil-
er with the combustion air/flue gas system that has been
specifically designed and approved for this type of boiler.
You must also observe:
− The local building regulations stipulating the installation
rules.
− The local building regulations concerning the air intake and
outlet systems and the chimney connection.
− The regulations for the power supply connection.
− The technical rules laid down by the gas utility company
concerning the connection of the gas connection to the lo-
cal gas main.
− The instructions and standards concerning the safety
equipment for the water/space heating system.
− The Installation instructions for building heating systems.
− The boiler must be located in an area where leakage of the
heat exchanger or connections will not result in damage
to the area adjacent to the boiler or to lower floors of the
structure. When such locations cannot be avoided, it is rec-
ommended that a suitable drain pan, adequately drained,
be installed under the boiler. The pan must not restrict
combustion air flow.
− The boiler must be installed such that the gas ignition
system components are protected from water (dripping,
spraying, rain etc.) during boiler operation and circulator
replacement, condensate trap, control replacement, etc.).
− The boiler must not be installed on carpeting.
− Do not restrict or seal any air intake or outlet openings.
− If you find any defects, you must inform the owner of the
system of the defect and the associated hazard in writing.

DANGER: Flammable gas explodes. Beware if you smell gas:
there may be an explosion hazard!
9
WARNING: RISK OF CARBON MONOXIDE POISONING OR FIRE DUE TO
JOINT SEPARATION OR PIPE BREAKAGE. Ensure all of the venting
system is properly supported and secured per these instruc-
tions, venting manufacturer's instructions and with the Na-
tional Fuel Gas Code, ANSIZ223.1/NFPA 54, CAN/CSA B149.1, and/
or applicable provisions of local building codes. Failure to do
so may result in substantial property damage, severe personal
injury or death.
