or repairing the heater onsite or at our factories including materials, parts, travel and labour. Electric and

warranty is limited to 80% of cost of repair at The Company’s then current rates and is limited to the cost
of labor, material and parts required for repair only. Only the manufacturer at address on this certificate will
determine in its sole and absolute discretion all warranty issues, and work claimed under warranty must be
approved in writing by The Company prior to any repairs being started.
If repair is not feasible for any reason as judged by The Company our obligations under this warranty are

General Conditions.
The warranty contained herein shall be voided if the heater is not installed and operated as instructed in the
owner manual. The hand over checklist must be signed by the customer and dealer and submitted along with
the warranty registration for this warranty to be valid. Heater must never be pressurized and pressurizing the
heater voids this warranty. A properly qualified tradesperson/s should perform all installations. If chimney
needs be extended an appropriately certified and approved insulated chimney must be used. Your dealer
may charge you for a service call to do warranty work. Parts will be replaced on an even exchange basis.
Polar Furnace updraft heaters are not intended to be the only source of heat. A backup system should be
in place to prevent resultant damage due to a lack of heat. Door seals, light bulbs, fire tending tools, heat
shields and any other wear items are not covered under this warranty. The insulated chimney is not covered
under this warranty. High temperature refractory materials are warranted for 1 year under this warranty.
In use, small cracks can occur in high temperature refractory and will not affect the performance of the
heater. Damaged caused by abuse, accidents, improper use, improper installation, excess creosote buildup,
overheating, freezing, corrosion, negligence, accidents in transit, and pressurization are not covered under
this warranty. Damage resulting from modifications or alterations will not be covered under this warranty. If
the serial number on the equipment is defaced, altered or removed this warranty is void. Damage caused by

e: [email protected] ph: 1.204.626.3381 f: 1.204.626.33264
burning flammable materials (such as petroleum products) or any other material besides properly prepared
wood will void this warranty. This warranty is limited to defective parts repair and/or replacement only,
and excludes any incidental and consequential damages. Only nontoxic antifreeze that meets and/or is
approved per all applicable regulations and standards may be used. The Company will not be responsible
for any environmental damages or charges resulting from use of toxic and or unapproved types of antifreeze.
Antifreeze will breakdown over a period of time and therefore should be tested annually. Always dispose
of antifreeze per federal, state, provincial, local or any applicable laws and regulations. Loss of antifreeze
under any situation and condition is not covered under this warranty. The Company is not responsible for
replacement of water, water treatment, antifreeze, removal, disposal, costs of transportation, or shipping
charges. Warranty does not include any plumbing, boiler piping, valves, controls or any other component
or system external to the boiler package. WARNING, The Company will not warranty the inside of the
fire drum due to ash corrosion. Rotation of ashes and/or stirring of firebox corners must be performed as
per the operator manual instructions and as displayed on the maintenance list located on the side of the
heater. WARNING, The Company will not warranty the water jacket due to corrosion from corrosive or
improperly treated water. An appropriate water treatment must be added and receipt retained for proof of
use to establish any warranty claims. We will not be liable to any contingency beyond our control including
war, strikes, floods, government restrictions or short supply of material. We will not be liable for any labor
cost, except above schedule. This warranty replaces and supersedes any and all other warranties, expressed
or implied, directly and or indirectly whether at law, common law, equity and/or statute and constitutes
the only warranty of The Company and the only liability of The Company. This warranty constitutes the
entire agreement between the parties with respect to the subject matter and supersedes all prior agreements,
negotiations, discussions, undertakings, representations, warranties and understandings, whether written
or verbal. This Warranty is governed by, and is to be construed and interpreted in accordance with the laws
of Manitoba and the federal laws of Canada applicable in Manitoba. The purchaser and The Company
each irrevocably agree to submit to the jurisdiction of the courts of Manitoba. The Company’s limitation of
liability pursuant to any warranty shall be equivalent in all respects to the sum of $1.00.
WARRANTY VOID IF NOT REGISTERED
