INSTALLATION
WARNING: The Massachusetts State Board re-
quires all installations be performed by a Licensed
Plumber or Gas Fitter. Massachusetts state code re-
quires all vent dampers be welded open or removed.
CAUTION: Do not remove the data plates at-
tached to the burner pan. The data plates contain
important warranty information.
WARNING: Before installing in a solid fuel burn-
ing fireplace, the chimney flue and firebox must be
cleaned of soot, creosote, ashes and loose paint by
a qualified chimney cleaner. Creosote will ignite if
highly heated. A dirty chimney flue may create and
distribute soot within the house. Inspect chimney
flue for damage.

ance must be performed by a qualified installer, ser-
vice agency, company or gas supplier experienced

tions and all codes and requirements of the authority
