Operations and deliveries are expected to be back on schedule today at Saint-Germain Bakery in Kalihi after an early morning fire yesterday that caused about $20,000 in damage.

The fire began before 1 a.m. at a 1930 Dillingham Blvd., and was brought under control about a minute after firefighters arrived.

Lorraine Yamada, the bakery’s administrative manager, said the fire damaged an oven exhaust vent, which serves two ovens in the three-story bakery.

She said production and deliveries were delayed for about an hour and half yesterday morning to its seven retail and wholesale outlets since many of the bakery products were damaged and had to be remade.

However, bakery operations should be back to normal today.

A fire investigator determined the fire was unintentional and began in the duct system used to direct heat and smoke from the ovens. Flames spread to roofing material and insulation on the roof.

All occupants of the building escaped without injury.

About 25 firefighters from four companies, including three engine companies, one ladder company, and a battalion chief, responded to the blaze and were on scene for about two hours making sure the fire was fully extinguished.
