WARNING

• Never tamper with the unit or its controls. User MUST contact a

specialized contractor when a failure occurs. DO NOT ATTEMPT
to repair.

• When using a humidifier make sure not to damage the heating

element bank.

• Poor maintenance of air filters OR an unbalanced static pressure

may result in a performance decrease.

• Always use genuine parts for maintenance or service call. The

use of unbranded parts will void the warranty. The use of this unit
without an air distribution duct will void the warranty.

• It is strictly forbidden to use jumpers to simulate heat demand.
• Risk of electrical shock. Disconnect power before installation,

servicing, maintenance or field wiring. Replace all panels before
operating. Failure to do so can result in electrical shock causing
severe injuries or death.

• When performing installation, servicing or cleaning the unit, it is

recommended to wear safety glasses and gloves.

• To assure a proper performance of your furnace, we recommend

that you use high quality name brand thermostats.

• When applicable local regulation comprises more restrictive

installation and/or certification requirements, the aforementioned
requirements prevail on those of this document and the installer
agrees to conform to these at his own expense.

• For your safety, do not store or use gasoline or other flammable

liquids and vapors in the vicinity of this unit or any other appliance.

• These instructions are intended to be used by qualified personnel

who have been trained in installing this type of furnace.
Installation of this furnace by an unqualified person may lead to
equipment damage and/or hazardous condition which may lead
to bodily harm.

• This furnace is not watertight and is not designed for outdoor

installation. This furnace shall be installed in such a manner
as to protect its electrical components from water.

Outdoor

installation leads to a hazardous electrical condition and to
premature furnace failure, thus voiding the warranty.

• Do not block the combustion air openings in the furnace. Any

blockage will result in improper overheat situation and may result
in a fire hazard and/or cause bodily harm.

• The unit must have an uninterrupted or unbroken electrical

ground to minimize personal injury if an electrical fault should
occur.

When performing electrical connection, the ground

conductor must be firmly attached to the ground lug in the
furnace.

• Do not use this furnace as a construction heater.

Use of

this furnace as a construction heater exposes the furnace to
abnormal conditions, contaminated combustion air and the lack
of air filters. Failure to follow this warning can lead to premature
furnace failure and/or vent failure which could result in a fire
hazard and/or bodily harm.

• The owner and/or the user is responsible of the following:

Always maintain the immediate surrounding of the furnace free
from combustible and highly flammables materials.The furnace
ambient air should not have an excessive dust concentration and
humidity. Never operate this central heating appliance without an
air filter.

• Before performing any service functions, unless operations

specifically require the power to be on, make sure all utilities are
turned “OFF” upstream of the appliance. Failure to comply with
this warning will cause a fire hazard and/or bodily harm.

• All questions regarding the operation, maintenance or warranty of

this unit should be addressed to the company where this product
has been sold from.

CAUTION

• Never burn garbage or paper in the heating system and never leave rags or paper around the unit.
• Return air grilles and warm air registers must not be obstructed.

IMPORTANT: All local and national code requirements governing the electrical installation heating equipment, wiring and
flue connections must be followed. Some of the codes that may be applicable are :

ANSI/NFPA 70 NATIONAL ELECTRICAL CODE

CSA C22.1 CANADIAN ELECTRICAL CODE

Only the latest issues of the above codes should be used, and are available from either:
