exclusions & Limitations

1.  This warranty is non-transferable.

.  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 pig-

ments has burned off. Overfiring in enamel stoves is 

identified by bubbling, cracking, chipping and discolor-

ation of the porcelain enamel finish. MHSC offers no 

warranty on chipping of enamel surfaces. Inspect your 

woodburning stove prior to accepting it for any dam-

age to the enamel.

3.  This warranty does not cover misuse of the stove as 

described in the Owners Guide, nor does it cover a 

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 Owners 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 Autho-

rized 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 ab-

sence, to the recommendations in our Owners Guide.

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

humidity environment, can be corrosive to the porce-

lain 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.

8.  MHSC shall have no obligation to enhance or update 

any unit once manufactured.  

IN NO EVENT SHALL MHSC BE LIABLE FOR INCIDENTAL 

AND CONSEQUENTIAL DAMAGES.  ALL IMPLIED WAR-

RANTIES, INCLUDING THE IMPLIED WARRANTIES OF 

MERCHANTABILITY AND FITNESS, ARE LIMITED TO THE 

DURATION OF THIS WRITTEN WARRANTY.  THIS WAR-

RANTY 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 limi-

tations 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 cus-

tomer should contact a Vermont Castings Authorized 

Dealer or MHSC if the purchase was direct with the fol-

lowing information:

1.  Name, address, and telephone number of the pur-

chaser

.  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., instal-

lation, mode of operation when defect was noted.

A warranty claim will then start in process. MHSC re-

serves the right to withhold final approval of a warranty 

claim pending a visual inspection of the defect by autho-

rized representatives.
