Bradford White 544-B User manual

Residential Combi2™
Energy Saver Oil-Powered Water Heater
Combi2™ Oil-Powered Model Features:
■Dual Purpose Heating—Provides domestic potable hot water and hydronic
heating in one energy saving system.
■Heat Exchanger—Double wall 11⁄2"O.D. glass coated (Vitraglas®)steel coil.
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®lining provides a tough
interior surface for our hot water tanks.
■Factory Installed Hydrojet®Total Performance System—Cold water inlet
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 areCompatible 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.
■Water Connections—3/4" NPT factoryinstalled true dielectric fittings
extend water heater life and eases installation.
■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 portion of tank. Reduces air movement in the heater during standby
periods to retard heat loss up the flue.
■Steel Tank—Heavy gauge steel automatically formed, rolled and welded.
■T&P Relief Valve—Installed.
■Brass Drain Valve.
■Design Certified by CSA International (formerly AGA/CGA).
