Alcove Installations
Because of their restricted air flow and heat retention characteristics, specific construction requirements and special clearances apply to installations into alcoves. No stove or chimney connector heat shields are used in alcove installations.
ALCOVE INSTALLATION OF THE DUTCHWEST MODEL #2477 IS PERMITTED IN BOTH THE US AND CANADA.
