1. GENERAL INFORMATION
1.1 General warningsInstallation
Read all safety warnings in the “Instruction Manual”. The additional safety issues outlined below must also be
followed completely when installing this FLOWMAX Combination Water heater.
Failure to remove or maintain the area free of combustible material, gasoline and other flammable liquids or vapours
can result in severe personal injury, death or substantial property damage.
All applicable local, state, national and provincial codes, ordinances, regulations and laws must be observed.
For installations in Massachusetts code requires the units to be installed by a licensed plumbing or gas fitter.
The appliance cannot operate without the correct amount of air for combustion. Please make sure there is sufficient
inflow and outflow of air for ventilation, never obstruct the flow of ventilation air. Failure to provide the proper amount
of combustion air can result in a fire or explosion and cause death, serious bodily injury or property damage.
If an external electrical source is utilized, the appliance, when installed, must be electrically grounded in accordance
with local codes or, in the absence of local codes, with the National Electrical Codes ANSI/NFPA 70 and or the CSA
C22.1 Canadian Electrical Code.
Follow all local codes and/or the most recent edition of the National Fuel Gas Code (ANSI Z223.1/NFPA 54) in the
USA or the Natural Gas and Propane Installation Code in Canada (CAN/CSA B149.1).
This unit is designed for indoor installations. DO NOT operate this unit without the vent piping connected. Exhaust
gases must be completely expelled out of the building.
Do not use this appliance if any part has been underwater. Immediately call a qualified service technician to inspect
the appliance and replace any part of the control system and any gas control which has been underwater.
Be sure not to reverse the water and gas connections as this may damage the gas valves.
Water temperatures over 125F can cause severe burns instantly or death from scalding. If the proposed water
heater outlet temperature is above 125F, a thermostatically controlled mixing valve (or a temperature limiting valve)
for reducing point of use water temperature is recommended to reduce the risk of scald injury. Contact a licensed
plumber or the local plumbing authority for further information.
The appliance should be located in an area where leakage within the unit or at its connections will not result in
damage to the area adjacent to the appliance or to lower floors of the structure. FLOWMAX will not be responsible
for any damage resulting from leaking if adequate drainage is not provided. When such locations cannot be
avoided, it is recommended that a suitable drain pan, adequately drained, be installed under the appliance.
Do not use this combination water heater for any purpose other than water heating and space heating.
The flow of combustion air and ventilation to the water heater must not be obstructed. The water heater area must
be kept clear and free from combustible materials, gasoline and other flammable vapours and liquids.
If the water quality is known to be highly acidic and/or extremely hard, water treatments (ie water softeners and
filtration) are recommended to maintain full warranty. Consult the local water authority.
DO NOT over-tighten fittings, as pipe and/or fitting damage may occur causing leakage.
DO NOT install water heater where subject to vibrations.
For other than a direct vent appliance, the appliance must be located as close as possible to a chimney or gas vent.
Should overheating occur or the gas supply fails to shut off, turn the manual gas control valve to the appliance.
Contact a Service Technician immediately.
Clearance must be in accordance with the local installation codes and the requirements of the gas supplier.
GENERAL INFORMATION
2
Never operate the heater unless it is vented to the outdoors and has adequate air supply to avoid risks of improper
operation, fire, explosion or asphyxiation.
DO NOT install this water heater directly on a carpeted floor. A fire hazard may result. The water heater shall be
installed on a metal or wood panel extending beyond the full width and depth of the water heater by at least 3 inches
(76.2mm) in any direction or, if the water heater is installed in an alcove or closet, the entire floor shall be covered
by the panel.
For safe operation, an ample supply of air must be provided for proper combustion and ventilation in accordance
with the National Fuel Gas Code ANSI Z223.1/NFPA 54 National Fuel Gas Code CSA/B149.1 Natural Gas and
Propane Installation Codes or applicable provisions of the local building codes. An insufficient supply of air may
result in a yellow, luminous burner flame, carboning or sooting of the heat exchanger, or create a risk of
asphyxiation. Do not obstruct the flow of combustion and ventilation air.
This unit is not intended to operate at gas supply pressures other than those shown on the rating plate. Exposure to
higher gas supply pressure may cause damage to gas valves, which can result in fire or explosion. If over-pressure
has occurred, such as through improper testing of gas lines or emergency malfunction of the supply system, the gas
valves must be checked for safe operation.
A thermostatic mixing valve must be added to this system to prevent scalding, if regulated by local codes and
authorities.
Check the Rating Plate
FLOWMAX units come from the factory configured for use with natural gas. Prior to installation, check the rating
plate of the water heater to ensure the unit matches gas type, gas pressure, water pressure and electrical supply. If
the unit does not match the requirements, do not install.
Be sure the gas type and electricity voltage match the rating plate.
There is a risk in using fuel burning appliances in rooms or areas where gasoline, other flammable liquids or engine-
driven equipment or vehicles are stored, operate or are repaired. Flammable vapours are heavy and travel along
the floor and may be ignited by the igniter or main burner flames causing fire or explosion. Some local codes permit
operation of gas appliances if installed 18 inches or more above the floor. This may reduce the risk if location in
such an area cannot be avoided. Flammable items, pressurized containers or any other potential fire hazardous
articles must never be placed on or adjacent to the water heater. Open containers of flammable materials should
not be stored or used in the same room with the water heater.
Do not install the FLOWMAX water heater in areas with excessive high humidity.
Do not install the unit in location where there is excessive humidity, such as a bathroom, damp crawl space, and
other areas with high levels of humidity. This may cause the unit to malfunction.
To avoid possible electrical shock, DO NOT touch the internal components of the water heater or the power cord
with wet hands.
DO NOT splash excessive water on the water heater when cleaning, as they are water resistant, not water proof.
Professionally qualified personnel in accordance with current laws and standards and in line with the manufacturer’s
instructions must install the appliance.
The commissioning of the water heater and any subsequent works carried out on the appliance must be effected by
an appropriately qualified technician.
The appliance must be used solely for the purpose for which it has been designed and manufactured: central
heating and domestic hot water production. Any other use is deemed as improper and as such dangerous. Under
no circumstances will the manufacturer be held responsible for damage or injury to persons or animals caused by
errors in the installation and/or use of the appliance, or through non-compliance with current local and national
standards and/or the manufacturer’s instructions.
The installation, operation and maintenance manual forms are an integral and essential part of the product and must
be kept with the appliance always.
