limited lifetime warranty

MHSC warrants that all refractory brick and material used in this product 

will be warranted against deterioration not resulting from physical dam-

age or overloading of the woodstove for the lifetime of this product. This 

coverage  includes  the  components  of  the  2N1  System:  “engine,  inner 

cover, access cover and fireback.” In addition all cast iron parts are war-

ranted against breakage, cracking or burn-through and glass door panels 

against thermal breakage. Coverage is provided only to the original pur-

chaser. MHSC will also pay labor associated with repairing or replacing 

the component described above for up to five years. 

limited 5 year warranty

The porcelain finish is warranted to be free of defects in material and 

workmanship for a period of five years from the date you purchase the 

stove. Warranty excludes chipping, scratching or other surface damage 

to the porcelain that might result from normal wear and tear and also 

excludes failure of porcelain coating due to misuse or overfiring.

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 purchase the stove: handles, gasketing and thermostat assembly
As designated in the descriptions above, MHSC will repair or replace, at 

its option, any part found to be defective upon inspection by a Vermont 

Castings, Authorized Dealer. The customer 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 au-

thorized at no charge to the customer for parts and/or labor. Labor rates 

will be determined by MHSC’s published labor rates in effect at the time 

labor is performed.
Any parts repaired or replaced during the limited warranty period will be 

warranted under the terms of the limited warranty for a period not to ex-

ceed 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 replace-

ment catalyst and the cost of labor necessary for its installation at the 

time of replacement.
A  third  year  (25  -  36  months)  of  no  charge  replacement  will  be  made 

when combustor 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 determination 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 lo-

cal 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 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 identi-

fied later by warped plates and areas where the paint pigment has 

burned off. Overfiring in enamel fireplaces is identified by bubbling, 

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.

3.  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 burning salt saturated 

wood, chemically treated wood, or any fuel not recommended in the 

Owner’s Guide.

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

than a Vermont Castings Authorized Dealer.

5.  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.)

6.  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.

7.  The salt air environment of coastal areas, or a high-humidity environ-

ment, can be corrosive to the porcelain enamel finish. These condi-

tions 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-humid-

ity environment. 

8.  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 incidental 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 con-

tact 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.
