- (a) Strainers must be installed in the fuel supply line. Each strainer must be self-cleaning, fitted with a bypass, or be capable of being cleaned without interrupting the fuel oil supply.
- (b) The strainer must not allow a quantity of air to be trapped inside which would affect the rate of fuel flow to the burner or reduce the effective area of the straining element.
- (c) The strainer must meet the requirements for strainers found in UL 296 (incorporated by reference, see [§ 63.05-1](/cfr/46/63.05-1.md)) and the requirements for fluid conditioner fittings found in [§ 56.15-5](/cfr/46/56.15-5.md) of this subchapter.
