DESCRIPTION
The Model OT-250 fuel tank is a 250-gallon, single-wall, indoor, UL
listed fuel oil tank. Oil tanks often eliminate needed work and storage
space, but the Model OT-250 oil tank is designed with a work bench
top that allows the tank itself to be used as a work area. The tank has
a large (12-1/2 sq. ft.) work surface with 2” side and rear retainer lips
and 3” legs allowing for “toe space”.
Tank construction is of 12 gauge carbon steel with all welded seems.
The tank painted exterior coordinates with Reznor® oil-red heaters.
The Reznor® Model OT-250 fuel tank is also engineered to faciliate
installation. The 3” tank support legs not only provide “toe space”
but are convenient for forklift handling. Each tank has the following
connection ports - 2”supply, 2”gauge, 2”vent, 4”emergency vent and
1”drain. Each port has heavy duty forged threads.
The model OT-250 tank is UL® listed to UL® 142 Standard. Reznor®
requires the use of UL listed or equivalent tanks with all Reznor® oil-
red heating products.
