heating in one energy saving system.

■ Heat Exchanger—Double wall 1

Two pipes guarantee that the potable water will stay separate from the
hydronic fluid. A positive leak path between the inner and outer pipes is
used to indicate leaks of either the domestic side of the coil or the hydronic
side of the coil.

■ Low Heat Exchanger Head Loss—Up to 10 GPM flow, with less than 5 ft.

of head loss. Greatly reduces the required pump size for heat exchange.

■ High Recovery Rates—Oil heats water 3 to 4 times faster than other

methods. This model is designed to assure a constant supply of hot water
provided the draw-off rate is within the recovery capacity of the unit.

■ Vitraglas

®

Lining—Bradford White water heater tanks are protected from

the corrosive effects of hot water by an exclusive ceramic porcelain-like
coating. The Bradford White high silica Vitraglas
interior surface for our hot water tanks.

■ Factory Installed Hydrojet

sediment reducing device helps prevent sediment build up in tank.
Increases first hour delivery of hot water while minimizing temperature build
up in tank.

■ Oil-Powered Burner—Beckett Burner with dual aquastat wired 120 Volt

1-stage with a firing rate of 0.85 GPH (Shipped with heater in a separate
box).

■ New Beckett Burners are Compatible with Biofuel—Up to B5

(5% Biofuel) can be used with water heater, provided the Biofuel meets
ASTM D6751.

■ Thermostatic Mixing Valve—Supplied with unit to help prevent injury due

to scalding.

■ Space Heating Connections—3/4" NPT female tappings on the front of

the water heater for easy pipe connections.

■ 1" Non-CFC Foam Insulation—Covers the sides and top of tank to save

energy by retarding loss of heat. Also increases jacket rigidity.

■ Two Protective Aluminum Anode Rods—Provide added protection

against corrosion for long trouble-free service.

■ Flue Baffle—Designed to maximize the amount of heat absorbed in the

lower por

tion of tank. Reduces air movement in the heater during standby

periods to retard heat loss up the flue.
