The Sentinel Ottawa DS Tunnel is a double-sided, steel, multifuel fireplace with clean lines and a cast iron door. The unit is manufactured for durability with a 10mm thick steel top and 5mm thick steel plate sides. Its design makes it suitable for any interior whether it is contemporary or traditional.

The Ottawa DS Tunnel has advanced clean burning with a tertiary clean burning system that re-burns the gases in the stove and results in higher efficiency and an eco-friendly product with lower fuel usage. There are primary and secondary combustion air controls and a pre-heated air wash system to help keep the glass cleaner for longer. The combustion chamber is lined with vermiculite firebrick and comfortably loads 40cm logs. It has a cast iron grate and a removable ash pan for easy cleaning.

Sentinel fireplaces are manufactured and imported from the Jiangsu Province in China for the South Africa market. Fireplaces come with a 3-year limited warrantee.
