Warranty 

limited 3 year Warranty

MHSC warrants that this woodburning stove will be free of defects in mate-
rial and workmanship for a period of three years from the date you receive 
it, except that the catalyst, thermostat assembly, handles, glass door pan-
els, cement, and gasketing shall be warranted as described below.
MHSC will repair or replace, at its option, any part found to be defective 
upon inspection by a Vermont Castings, Authorized  Dealer.  The cus-
tomer must return the defective part or the stove, with shipping prepaid, 
to the Authorized Dealer or pay for any Authorized Dealer in-home 
travel fees or service charges for in-home repair work.  It is the dealer’s 
option whether the repair work will be done in the customer’s home or 
in the dealer’s shop. If, upon inspection, the damage is found to be the 
fault of the manufacturer, repairs will be authorized at no charge to the 
customer for parts and/or labor.
Any woodburning stove or part thereof that is repaired or replaced dur-
ing the limited warranty period will be warranted under the terms of the 
limited warranty for a period not to exceed the remaining term of the 
original limited warranty or six (6) months, whichever is longer.

limited 1 year Warranty

The following parts of the woodburning stove are warranted to be free 
of defects in material and workmanship for a period of one year from 
the date you receive it:  The thermostat assembly, handles, glass door 
panels, cement, and gasketing.  Any of these items found to be defec-
tive will be repaired or replaced at no charge, upon the return of the part 
with postage prepaid to a Vermont Castings Authorized Dealer.
Any part repaired or replaced during the limited warranty period will 
be warranted under the terms of the limited warranty for a period not 
to exceed the remaining term of the original limited warranty or six (6) 
months, whichever is longer.

limited catalyst Warranty

The catalyst will be warranted for a six year period as follows:  If the 
original catalyst or a replacement catalyst proves defective or ceases to 
maintain 70% of its particulate emission reduction activity (as measured 
by an approved testing procedure) within 24 months from the date the 
stove is received, the catalyst itself will be replaced free.  
From 25 - 72 months a pro-rated credit will be allowed against a re-
placement catalyst and the cost of labor necessary for its installation at 
the time of replacement.
For stove purchases made after June 30, 1990, a third year  
(25 - 36 months) of no charge replacement will be made when combus-
tor failure is due to thermal degradation of the substrate (crumbling of 
ceramic material).  The customer must pay for any in-home travel fees, 
service charges, or transportation costs for returning the stove to the 
Authorized Dealer.

Any replacement catalyst will be warranted under the terms of the 
catalyst warranty for the remaining term of the original warranty.  The 
purchaser must provide the following information in order to receive a 
replacement catalyst under the terms of this limited warranty:

1.  Name, address and telephone number.
2.  Proof of original purchase date.
3.  Date of failure of catalyst.
4.  Any relevant information or circumstances regarding determina-

tion of failure.

5.  In addition, the owner must return the failed catalyst.

exclusions & limitations

1.  This product must be installed or serviced by a qualified installer, 

preferably NFI or WETT (Canada) certified, as prescribed by the 
local jurisdiction. It must be installed and operated at all times in ac-
cordance with the Installation and Operating instructions furnished 
with the product any alterion, willful abuse, accident or misuse of 
this product shall nullify this warranty.

2.  This warranty is transferable; however, proof of original retail pur-

chase is required.

3.  This warranty does not cover misuse of the stove.  Misuse includes 

overfiring which will result if the stove is used in such a manner as 
to cause one or more of the plates to glow red.  Overfiring can be 
identified later by warped plates and areas where the paint pigment 
has burned off.  Overfiring in enamel fireplaces is identified by bub-
bling, cracking, chipping and discoloration of the porcelain enamel 
finish.  MHSC offers no warranty on chipping of enamel surfaces. 
Inspect your woodburning stove prior to accepting it for any damage 
to the enamel.

4.  This warranty does not cover misuse of the stove as described 

in the Owner’s Guide, nor does it cover an stove which has been 
modified unless authorized by a MHSC representative in writing.  
This warranty does not cover damage to the stove caused by burn-
ing salt saturated wood, chemically treated wood, or any fuel not 
recommended in the Owner’s Guide.

5.  This warranty does not cover a stove repaired by someone other 

than a Vermont Castings Authorized Dealer.

6.  Damage to the unit while in transit is not covered by this warranty 

but is subject to a claim against the common carrier.  Contact 
Vermont Castings Authorized Dealer from whom you purchased 
your stove or MHSC if the purchase was direct.  (Do not operate the 
stove as this may negate the ability to process the claim with the 
carrier.)

7.  Claims are not valid where the installation does not conform to local 

building and fire codes or, in their absence, to the recommendations 
in our Owner’s Guide.

8.  The salt air environment of coastal areas, or a high-humidity en-

vironment, can be corrosive to the porcelain enamel finish. These 
conditions can cause rusting of the  cast iron beneath the porcelain 
enamel finish, which will cause the porcelain enamel finish to flake 
off. This warranty does not cover damage caused by a salt air or 
high-humidity environment. 

9.  MHSC shall have no obligation to enhance or update any unit once 

manufactured.

IN NO EVENT SHALL MHSC BE LIABLE FOR INCIDENTAL AND CON-
SEQUENTIAL DAMAGES. ALL IMPLIED WARRANTIES, INCLUDING 
THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS, 
ARE LIMITED TO THE DURATION OF THIS WRITTEN WARRANTY. 
THIS WARRANTY SUPERCEDES ALL OTHER ORAL OR WRITTEN 
WARRANTIES.
Some states do not allow the exclusion or limitations of incidential and 
consequential damages or limitations on how long an implied warranty 
lasts, so the above limitations may not apply to you. This warranty gives 
you specific rights and you may have other rights which vary from state 
to state.

how to obtain Service

If a defect is noted within the warranty period, the customer should 
contact a Vermont Castings Authorized Dealer or MHSC if the purchase 
was direct with the following information:

1.  Name, address, and telephone number of the purchaser.
2.  Date of purchase.
3.  Serial number from the label on the back.
4.  Nature of the defect or damage.
5.  Any relevant information or circumstances, e.g., installation, 

mode of operation when defect was noted.

A warranty claim will then start in process.  MHSC reserves the right to 
withhold final approval of a warranty claim pending a visual inspection 
of the defect by authorized representatives.
