Page 29: Maintenance And Safety
B36LA & B36RA Woodburning Fireplaces MAINTENANCE & SAFETY Fuel Storage Wood can be dried sufficiently for burning within a few weeks if protected form rain in a low humid- ity area. It is far better to cut wood and allow it to dry for a year. In all cases, the wood should be stacked so that both ends of the sticks are exposed to the air and protected from rain. -
Page 30: Fireplace Maintenance
B36LA & B36RA Woodburning Fireplaces MAINTENANCE & SAFETY Fireplace Maintenance At the end of each heating season or when the fireplace will not be in use for an extended time, the ashes should be removed and the hearth area should be swept as clean as is practical. The slow ab- sorption of moisture into the ashes over a long period of time could cause a condition which would be corrosive to the metal fireplace parts. - Page 31 B36LA & B36RA Woodburning Fireplaces MAINTENANCE & SAFETY DONT’S 1. Don’t allow other installations or operation considerations to take priority over safety considerations. 2. Don’t attempt to use the fireplace until the installation is complete. 3. Don’t use unlisted parts and accessories with the fireplace except for special flashings that may be fabricated locally.
