1.2 General safety instructions
If you hear gas leaking
▶ Leave the building immediately.
▶ Prevent others from entering the building.
▶ Notify the police and fire department from outside the building.
▶ From outside the building, call the gas supply company and a trained
and certified installer or service company.
If you smell gas
▶ Turn off the gas shut-off valve.
▶ Open windows and doors
▶ Do not touch any electrical switch, telephone, and do not use outlets.
▶ Extinguish all open flames.
▶ Do not smoke!
▶ Do not use lighters!
▶ Warn all occupants of the building that they need to leave the
building.
▶ Do not ring doorbells!
▶ Notify the police and fire department from outside the building.
▶ From outside the building, call the gas supply company and a trained
and certified installer or service company.
If you smell flue gas
▶ Switch off the heating system by shutting off the emergency shut-off
switch.
▶ Open windows and doors.
▶ Call a trained and certified installer or service company.
DANGER: Risk of fatal injury from failing to consider your own
safety!
▶ Never risk your own life. Your own safety must always take the
highest priority
NOTICE: Risk of appliance damage from improper operation of the
boiler!
▶ Only use the boiler for its intended purpose.
▶ Only operate the boiler if it has been installed and maintained per the
instructions provided in the Installation Manual.
▶ Do not attempt to operate an appliance if any part of it is not in
working order or is damaged.
▶ Use only original spare parts! The use of parts not supplied by the
manufacturer may cause damage to the boiler, other property and
personal injury. Also, boiler damage caused by the use of
unauthorized parts is not covered by the warranty.
DANGER: Risk of fire when soldering and brazing!
▶ Take appropriate protective measures when soldering and brazing
around combustible and flammable material.
NOTICE:
▶ The installation must comply with all applicable national, state, and
local codes, rules, and regulations.
▶ The operator is responsible for the operational safety and regulatory
compliance of the heating system.
▶ In the Commonwealth of Massachusetts, the appliance must be
installed by a licensed plumber or gas fitter.
DANGER: Risk of personal injury or death from flue gas poisoning!
▶ Do not install a thermostatic flue gas damper downstream of the draft
hood.
▶ Do not tamper with, remove, or attempt to repair the blocked vent
switch.
▶ When replacing the blocked vent switch, install the new part in the
original location.
▶ A blocked vent switch tripping more than once indicates a problem
with the venting system or chimney which must be repaired
immediately.
▶ Ensure none of the vent pipes and chimneys are damaged or blocked.
▶ Connect only one appliance to each venting system or chimney.
▶ The venting system must not feed into or route through another air
extraction duct.
▶ The venting system must be inspected annually. All parts that show
any signs of damage or corrosion must be replaced.
▶ Never close off or reduce the size of the combustion air openings.
▶ The boiler must not be operated until any obstructions have been
removed.
DANGER: Risk of personal injury or death from explosion!
▶ Work on gas components may only be carried out by a trained and
certified installer or service company.
▶ Appliance installation, the connection of gas and vent piping, initial
commissioning, electrical connections, and service and maintenance
must only be carried out by a trained and certified installer or service
company.
DANGER: Risk of personal injury or death from fire!
▶ Do not use flammable or combustible material in the boiler room.
▶ It is recommended not to store any items within 16 inches (415mm)
of the appliance
CAUTION: Appliance damage from contaminated combustion air!
▶ Keep the combustion air free of corrosive substances, e.g.
halogenated hydrocarbons from painting operations or beauty
salons.
▶ Keep combustion air free from dust and lint, e.g. from laundry or
agricultural operations.
▶ If clean room air is not available, fresh outdoor combustion air must
be provided
DANGER: Risk of personal injury or death from electric shock.
▶ Before removing the front panel, disconnect the heating system from
the electrical power supply by shutting off the emergency shutoff
switch or the heating system circuit breaker.
▶ It is not enough to switch off the control panel. Power to the panel
must be disconnected! Ensure that the power is not restored
unintentionally by following proper lock out/tag out procedures.
▶ Only qualified electricians are permitted to carry out electrical work.
DANGER: Safety devices!
▶ Never shut off safety valves!
▶ Hot water may escape from the safety valve at any time when the
appliance is running.
DANGER: Risk of personal injury or death after a flood!
▶ Do not attempt to operate an appliance if any part of it has been
under water.
▶ An appliance that was subject to flooding must be replaced.
NOTICE:
▶ Upon completion of the installation, these instructions should be
handed to the owner and operator of the appliance.
▶ The installer must instruct the owner and operator on the
functionality of the components and the proper operation of the
boiler and the heating system.
▶ The boiler must be serviced annually including the main burner,
ignition burner, the entire venting system, and the combustion air
supply. All parts that show any signs of damage or corrosion must be
replaced.
